Hike with a Botanist at Rough and Ready Botanical Wayside 

Rough and Ready Creek near the start of the trail.

Hiking along the dry, dusty trail that leads out onto the Rough and Ready Flat on a hot summer day, it is hard to fathom how ecologically significant it is. Strewn with rocks and sparse vegetation, including a few straggly-looking trees, it is no Amazonian rainforest. Yet, it hosts a spectacular array of botanical delights that deserve a closer look.

Rough and Ready is one of only about 200 biologically outstanding areas in the United States and is home to the greatest amount of plant biodiversity in the State of Oregon. So, though it may appear desolate, it is a botanist’s dreamscape—full of a variety of native and endemic species!

Of course, I had to check it out! This is what brings me back to that dry dusty trail, where I met with BLM Botanist, Amanda Snodgrass, to learn more about Rough and Ready Botanical Wayside near Cave Junction, OR, and what it is like to be a botanist.

The Hike

  • Trailhead: Rough and Ready Botanical Wayside
  • Distance: 0.3 mile interpretive trail with the option to extend the hike by following established road tracks.
  • Details: Ample parking at trailhead. Covered picnic table is available at the trailhead with another table near the end of the trail. No restroom.

On Being a Field Botanist

It was early morning but already warm as Amanda and I strode across Rough and Ready, taking the only trail out onto the flat lands.

Energy high, Amanda told me a bit about her background as a Botanist.

Originally from Iowa, Amanda moved to the area in 2018 and only recently, about eight months ago, took up her post as a Field Office Botanist for the BLM Medford District. She had become fascinated by plants at a young age during a trip to Hawaii and has enjoyed studying and learning about them ever since.

“I like plants. I am a plant person,” Amanda remarked. “They are pretty and resilient, and they don’t talk back.”

Zingers, like this one, seemed to tumble out of Amanda. For a self-professed plant person, she was rather personable. Even though she claimed, “plant people usually aren’t people, people.”

I asked Amanda to explain more about what it is like to be a “plant person,” or more professionally speaking, a field botanist.

“I oversee the botanist program for the Grants Pass field office,” Amanda explained. “I do a lot of fieldwork, but I also do a lot of paperwork.”

Most of that paperwork is around managing botanical resources in terms of NEPA (National Environmental Policy Act). BLM land is managed for multiple uses, so that means it may be used for a variety of activities, like recreation, mining, or extracting forest products. Amanda’s job is to ensure important botanical resources are protected while still allowing for these activities.

“I still get to do a lot of fun stuff, too,” said Amanda, “like plant surveys, monitoring, restoration work, and a lot of invasive species management.”

According to Amanda, the job is “50/50,” about half of her day-to-day is paperwork and the other half is with the plants. It was clear what part is her favorite.

Meandering

As we meandered down the trail, Amanda described some of what goes into surveys and monitoring for a field botanist.

One of the hallmark surveys she conducts is a “clearance survey.” These are done whenever there is going to be a disturbance in the areas to check for rare species, as well as gather basic information on habitat type and species associations to measure overall ecosystem health.

Long-term monitoring, revisits, plots, and transects… all of these are part of a botanist day to day fieldwork.

Perhaps most intriguing was Amanda’s mention of a “meandering survey.” “It is intuitively controlled,” she explained. Essentially, you are looking at the habitat and predicting what species may be present, and then wander around to see if you can find said species.

“It’s a botany special,” smirked Amanda.

Rough and Ready

We ambled further into Rough and Ready.

I began to take notes of the ecosystem around us.  We passed by a view down to wide and braided, Rough and Ready Creek rushing over a bed of cobbles. Low shrubs, mostly ceanothus ran in clumps along the trail with wide sections of open ground where grasses and herbaceous plants grew in scarce quantities. A few pine trees marked the canopy, separated by 10s-of-feet. Flashes of color came from a few wildflowers. The ground itself was gritty, and rocky, appearing less than hospitable to the vegetation—yet stuff was growing.

According to Amanda, Rough and Ready is a part of the Klamath-Siskiyou ecoregion known as the Illinois River Valley. To start, these ecoregions are known for their botanical diversity. But when you add in the unique characteristics of Rough and Ready, the biodiversity is even more amplified.

“It is one of the most botanically biodiverse ecosystems in North America,” said Amanda. While in Oregon, is considered the most botanically diverse. That is nothing to snuff at.

So, I asked Amanda, “Why?” What is it about Rough and Ready?

“It has its own special characteristics,” Amanda responded.

She went on to explain how it is the unique geology, hydrology, and climate that help provide opportunities for diversity to flourish. 

Geologically speaking it has serpentine soils—“aged metamorphic soil, high in minerals like magnesium and nickel.”

Heavily mineralized, ultramafic soil is difficult for most plants—making important nutrients like calcium and nitrogen unavailable, while subjecting plants to heavy metals at toxic levels. 

“Many plants can’t grow in it and the ones that do often can only grow on it,” Amanda elaborated. 

Additionally, Rough and Ready is unique hydrologically, receiving more rainfall compared to adjacent areas.

“It can get over 100 inches of rain a year!” Amanda exclaimed.

Water is carried down from the mountains and distributed onto a broad alluvial floodplain and alluvial bench which hosts a variety of species.

The climate at Rough and Ready is also variable throughout the watershed.

“It has several elevations,” stated Amanda.

With influences from the Pacific Ocean, Coast Ranges, Cascade peaks, and the deserts of the Great Basin, the area has a variety of habitat zones, determined by the physiology and changes in precipitation levels that shift with elevation.

All in all, this makes Rough and Ready “second in North America for endemism,” according to Amanda. In other words, there are a lot of unique species here that you wouldn’t find anywhere outside the region.   

“Are we going to find any of them?” I asked.

 “Yes, they are all around!” exclaimed Amanda jubilantly.

Pining for Pines

At this point, we reached a tall berm of ultramafic, heavily mineralized soil.

“Well, the trail work must have stopped here,” smiled Amanda, as we climbed over the barrier.

After successfully navigating over the dry sluff of soil, it was time to get down to business—the business of plants.

Are these all Jeffery Pines?” I asked Amanda, pointing to the nearest tree that stood a few feet off the trail.

“Yes,” she responded, “we have a really high percentage of Jefferey Pines. Though in this spot they tend to be straggly.”

Again, the soil was doing its thing—binding the nutrients and stunting growth.

Amanda was a bit surprised by my enthusiasm for the trees, but she was willing to humor me.

Jefferey Pine (Pinus jeffreyi) is one of only two species of pine that has needles bundled in groups of three in Oregon. The other species, Ponderosa Pine (Pinus ponderosa), is much more common and also found at Rough and Ready. So, how can one distinguish between these two look-alikes?

“Gentle Jeffery,” Amanda mused… “and Poky Ponderosa.”

She went on to explain that one of the best ways to tell these two pines apart is by their cones. Ponderosa Pine’s cones tend to be larger, at least 6 inches with more pronounced sharp prickles on their scales; while Jeffery Pine’s cones are usually smaller than 6 inches, with scales that point inward. The needle colors can also be a distinguishing factor—Jeffrey Pines have greenish gray needles and Ponderosa have bright green to yellow needles.

“Sometimes you can smell them,” she added. Ponderosa Pine usually has a sweet scent like pineapple or vanilla.

Of course, this is one place where relying on all your senses might come in especially handy.

“A lot of places there is only one type of pine,” Amanda extolled. But, “Oregon is home to roughly 30 species of conifers, and the Klamath-Siskiyou Ecoregion is home to 36 species of conifer across Southern Oregon and Northern California.

Ah, for the love of conifers! This is my sort of place.

Jeffrey Pines are common at Rough and Ready

Keying in on Family Ties

Head out of the trees, Amanda soon directed my attention downward. Colorful puffs of yellow and bright white grew from long stems along the trail.

“Buckwheat,” Amanda confirmed.

But how can you tell? It isn’t easy. For the buckwheat family, in particular, you may even need a microscope to get down to the species level.

“It can take hours to key out a plant,” Amanda explained. “One thing that happens in this ACEC (area of critical environmental concern) is there is a lot of hybridization.” In other words, a lot of mixing of genes between species that can make keying out a species even more difficult.

However, with the right tools, including a good identification book or app, it can be done. Amanda recommended the “Oregon Wildflowers” App put out by Oregon Flora, as well as several regional books, including A Flora of California by Munz and The Jepson Desert Manual by Baldwin, et al. 

Amanda pulled out a species list to help narrow things down, and after some careful study and using the wildflower app, was able to identify the yellow buckwheat as ternate buckwheat (Eriogonum ternatum) and the white as sulfur buckwheat (Eriogonum umbellatum).

Okay, so getting down to species may at times become challenging, especially in biodiverse areas. There is at least eight known buckwheat in Rough and Ready, for example. But there is something to be said for identifying to family-level as well. 

Family groups often share some common characteristics. This is true of the buckwheat family as well.

“A lot of the times buckwheat have a basal rosette and then bare stems that come up with these puffs of flowers that turn color over time,” Amanda described. “The leaves are also often spoon-shaped,” she added.

“Spoon leaves,” I let it roll off the tongue. What a way to keep things straight!

“There is all the formal terminology,” continued Amanda, “but I think it is helpful” to use your own terms as well to help distinguish and remember individual plants.

Other families share other characteristics. A few of the families found at Rough and Ready Amanda described include: The Allium Family with their clusters of flowers and pungent linear leaves. The Asparagus family with lance-shaped leaves and parallel venation and often bell-shaped flowers. And the Lily family with 6 petals with three to 6 stamen and leaves often arising from low to the ground.

Spring Flowers

Amanda and I continued to note the various wildflower species along the trail as we hiked—lavender, spiky-looking ookow (Dichelostemma congestum) and purple with sharp, curved petals, Harvest Brodiaea (Brodiaea elegans). We also discovered a small rock fern called Indian’s dream (Aspidotis densa)—what a name!

Eventually, we reached a junction and headed left, following the powerlines on an old roadbed toward the river.

Speaking of colorful wildflowers, I asked Amanda when should people visit Rough and Ready for the best wildflower show.

Though there was plenty to see in these early summer months, Amanda recommended returning in spring.

“Spring is nice because you get the first wildflower blush,” she said. “Early spring wildflowers have a high percentage of endemic species.”

Many of the Irises and Calochortus (including mariposas) show up in spring—both of which have endemic species.

However, according to Amanda, any time is a good time to visit.

“What is cool about this site is it changes throughout the year and as you head up in elevation.”

Shrubs

However, there are some species that can be seen year-round. In addition to the conifer species, hardwood trees and shrubs are also year-round residents of Rough and Ready.  And we saw a lot of them on the trail! So many that, of course, I asked Amanda about it.

She patiently humorous me as we walked along noting species, like deer brush (Ceanothus integerrimus), birchleaf mountain mahogany (Cercocarpus betuloides), and spicy-smelling California Yerba Santa (Eriodictyon californicum).

“It is known as ‘holy weed’ or ‘holy herb’ and is the borage family,” shared Amanda regarding the California Yerba Santa.

We walked past an unusual-looking oak. 

Whipping out the plant list, Amanda stated: “We have seven oaks here in Rough and Ready.”

She then pulled open her Oregon Wildflower App to see if she could narrow things down.

“I think it is Brewer’s oak,” said Amanda after some deliberation. “The Brewer’s Oak is a hybrid of the Oregon White Oak.”

It looked Oregon White Oaky to me.

Possible Brewer’s oak leaves.

Amanda admitted she rarely spends much time on shrubs, as we ran across a myriad of manzanita.

“There are three types of Manzanitas here,” said Amanda.

Again, she worked to narrow down the ones surrounding us. “I think it is hoary manzanita,” she proclaimed, noting the wooly twigs and branches.

 We didn’t attempt to identify any of the others. Apparently, manzanita are known to hybridize, making identification even more complicated. Those darn shrubs!

Waters Edge

We continued down the “powerline trail,” passing a cluster of California poppies (Eschscholzia californica). Soon, we reached the rocky shores of Rough and Ready Creek.

Here we decided it was best to loop back. So, we carefully, balanced along the rocky creek edge, passing by a camas lily as we went.

Following the water’s edge, our garden of flowers was even more sparse. We focused on the rocks under our feet as we hopped along.

“So, these are all very serpentine rocks,” remarked Amanda as she picked up a rock to show me. “See the green color. There is asbestos in these rocks.”

There were also a lot of reddish rocks—another serpentine rock, only derived from peridotite, instead of serpentinite which yield the more dazzling green colors. 

All these rocks weather to a reddish-colored soil characteristic of serpentine geology.

Adaptations

We carefully clambered over the colorful rocks, careful to avoid the delicate desert soil. It was hot with the sun and only a few clouds dancing overhead.

Which brings us right back to the question: how do species adapt to this harsh environment? How do they deal with, as Amanda called them “asbestos rocks,” among the many other challenges?

Amanda and I discussed the problem throughout our hike—touching on the various challenges of the region.

As discussed earlier, serpentine rocks are characteristically high in certain minerals, like heavy metals. To overcome this, many species of plants might exclude heavy metals, reduce their transfer through the plant, or concentrate it in certain tissues at unusually high levels. 

When it comes to living in a relatively dry, sunny environment—where evapotranspiration is high—plants take different approaches to reduce water loss and protect from the sun.

“Many of them have leathery leaves or coatings…” said Amanda, and/or “different types of furry leaves and stems.”

Leathery or coated leaves help reduce water loss by reducing evaporation, as well as provide insulation from the sun and cold. While the hairs of furry leaves are helpful for reflecting sunlight and reducing airflow and drying. 

Wildfire

Wildfire is another challenge for species in the Klamath-Siskiyou ecoregion.

“There are three kinds of species—species that tolerate wildfire, those that don’t, and those that require it,” said Amanda. “Here, many require it.”

Those that require fire might need it for a variety of reasons. Some conifer species have serotinous cones—cones that require fire to open and release seeds. Many herbs and forbs have seeds with hard seed coats that need fire, or some other harsh environment, to break that coat to germinate.

“A lot of plants are adapted to fire because it makes nutrients available,” Amanda continued. “After a burn, big blooms of vegetative growth often occur.”

Other species, like oaks, will resist fire. Oaks have thick bark that protects them from lower-intensity fires. While, manzanita, on the other hand, burns fast and hot, but can regenerate easily—resprouting from burls at the base of the shrubs.

However, Amanda warned that changes in the fire interval—the amount of time between fires—could have negative effects on some species and their ability to tolerate fire.

“Burn too frequently, nothing reestablishes,” she said, “not enough, and there is too much competition.”

Non-native species also often arrive following a fire which can complicate things further. Non-native grasses, for example, often come in following fire. The problem is that these grasses create an ecosystem prone to more fire. More fire means more grasses, and on and on.

To sum up, native species are adapted, not only to fire, but to a specific fire regime and a very specific plant community. Changes in either of these can lead to native ecosystem loss. 

Why Plants Matter

As we continued to traverse the cobbles, having seen some of the diversity of species to discover at Rough and Ready, I asked Amanda why we should care about all these plants anyway? Do plants really matter?

This was her response:

“Plants are foundational components in high-functioning systems that support other species and the human population. They are the fundamental backbone. All our materials come from plants, they are the source of food, clothes, drugs, material, and they are also an indicator of ecosystem health.”

She went on:

“Diversity is stability. It is easy to overlook plants because they don’t make any noise. But, they are all around us and necessary for the survival of all species. I like them because they are quiet underdogs. But really, they are important and we need to preserve the diversity of different species.”

Amanda continued to explain how, despite their immense value to the ecosystem and our human societies, plant populations are being threatened by climate change, habitat loss, and many other stressors.

“We need people to speak for them,” proclaimed Amanda. “It is important to have people that care and are willing to support the plants and their communities because we all depend on them for survival.”

You could really hear the passion and concern behind Amanda’s words.

“Cheese-fest?” she smiled, then shrugged. “It’s just how I feel.”

I smiled and kept on rock hopping. Did I just hear a mic hit the floor? 

Keep a Close Watch

Looking out for the botanical resources on BLM is a big part of Amanda’s job, but this has proven difficult as threats are often mounting.

Amanda expressed concern for the plants at the Rough and Ready.

“The other thing about plants is because they are slower at migrating, it is easier for them to just be gone.”

She used several examples of how species tend to be closely connected to their environments. Again, she reminded me how serpentine species need serpentine soils to survive. Then there are saprophytic plants, like snow plants and ground cones, that need specific trees with a specific microbiome to be happy.

“Everyone loves the calypso orchids,” she expounded, “but you can’t pick them up and move them…they are connected with the mycorrhiza of the soil.”

Then, there are threats from “their own kind”—invasive species take up a lot of Amanda’s time.

“They are a major threat to the integrity of the ecosystem and it takes a lot of time and energy to make progress on it,” she explained regarding her efforts.

“What else?” I asked. “What are the biggest threats to the plants here?”

Amanda spoke of the challenges that her district specifically faces, including illegal marijuana grows, offroad recreation, and illegal dumping.

“French flat is one of our highest intact pieces of habitat for Lomatium cookii, a federally listed species,” said Amanda. “And we are constantly having trouble with off-road vehicles.  There are a lot of burned-out cars there, ”she sighed.

As if on cue, we crossed by some trash on the trail. 

“I lose faith in humans sometimes,” she remarked as she bent down to pick it up.

Enjoy Plants

At this point, we decided to begin veering back to the normal trail, but before we made it over the rocky rise, I asked Amanda for advice—how can people enjoy plants?

She had a lot of ideas, but her main message was simple—leave a place better than you found it. Care about plants and share how your care with others.

She also suggested making small goals to help plants.

“Think of your own yard. Do you have some native flowering plants?  That is your base. There is a food chain that connects all the way up from there.”

And, of course, spending time with plants, was her last piece of advice.

“Visit a local park or somewhere nearby and instead of just walking, stop in a spot and look around. Count how many different plants you think you see.”

Amanda recommended reaching out to organizations, like a local native plant society, to learn more about the plants. 

“Peak curiosity… “ After all, once you have truly seen a plant “you can’t unsee it!”

Species List

Amanda and I carefully made our way up the hill and back to the main path. As we walked, I asked Amanda if she could give me a short list of species for the area that she “can’t unsee.” What species could someone visiting the Klamath-Siskiyou learn to appreciate first?

This proved to be the most difficult question of the day—she came up with a few, but later sent me her complete list.

First, the trees. Pacific Madrone (Arbutus menziesii), Brewer’s Spruce(Picea breweriana), Port Orford Cedar(Chamaecyparis lawsoniana), and Pacific Yew (Taxus brevifolia) were Amanda’s picks. 

“They are easily recognizable, native, and all have some personality or rich history,” said Amanda.

Pacific Madrone, for example, has a hard, dense wood with “eucalyptus-like bark,” both smooth and peeling.

Later she added knobcone pine (Pinus tuberculata) to the list—as it is one that is especially dense at the Oregon/California border.

Next, shrubs. Oregon Grape (Mahonia aquifolium) was her first pick.

“It is an indicator of a native ecosystem,” said Amanda of the Oregon Grape. “It’s fruits edible, roots medicinal, and pollinators love it!”

Later she added: Huckleberry Oak (Quercus vacciniifolia), Deer Oak (Quercus sadleriana), and Hupa Gooseberry (Ribes marshallii).

Finally, the flowers!

Originally, Amanda suggested beargrass (Xerophylllum tenax) and Cobra Lily (Darlingtonia californica) to add to the list. Both are unique enough to identify easily and have unique life histories and/or cultural significance.

“Beargrass has a unique flower stalk,” said Amanda. “It is culturally significant to a number of native tribes and is an indicator of the Pacific Northwest Coast Region.”

Later she added: Clustered Lady Slipper (Cypripedium californicum), Gentner’s Fritillary (Fritillaria gentneri), Howell’s Camas (Camassia howellii), Siskiyou Iris (Iris bracteata), and Splithair Indian Paintbrush (Castilleja schizotricha)

Botanical Discoveries

It was still morning when we made it back to the trailhead, so we decided we would check out the Eight Dollar Mountain site just a short drive away before taking parting ways.

At Eight Dollar Mountain, we found a lot of other interesting species, including an amazing view of a Darlingtonia fen in bloom, and many endemics. 

However, my favorite moment on this pit stop was when we first arrived and headed up the road to the boardwalk. Amanda suddenly made a beeline off the side of the road. I followed.

A scattered patch of beautiful large white blooms with hairy petals and pink stamen ringed in a reddish brown grew there from their tall thin green stems. Neither of us had seen these flowers before. The excitement was palpable.

Giddy with our new find, Amanda dove into her reference materials and shortly was able to identify it as Howell’s Mariposa Lily (Calochortus howelii)—a local endemic. We would soon find out it was very common to the site—a lot of it grew along the boardwalk trail—but at that moment, it was new, fresh, and exciting.

And there it was—botany in action, the joy of discovery.

Howell’s Mariposa Lily (Calochortus howelii).

I discovered a lot on my hike with Amanda.

Though, I started out the day loving botany (Yes, I am a plant nerd). Experiencing Amanda’s passion and persistence was both heartening and renewing—like seeing a new plant for the first time. Seriously, it doesn’t get better than that!

Hike with a Sports Product Designer

Looking down the Wildwood Trail near the Newberry Trailhead

One thing that I love about hiking is its simplicity. You don’t have to invest in a bunch of gear to become a hiker—although some people do. All you need are a good pair of shoes and a pack filled with necessities, and you are off to the races.

At the same time, the sport of hiking is ripe for product innovation. Hikers are ready for products that improve performance, safety, and overall function. I mean, honestly, a good pair of shoes can be difficult to come by.

Which begs the question, how do hiking products come to market? What is the design process for a hiking shoe or pack?

On a cool spring day, I met with Susan Sokolowski, director of the Sports Product Design Program at the University of Oregon, and Henry Gilbert, one of her students enrolled in the program, for a hike on the Wildwood trail to find out.

The Hike

  • Trailhead: Newberry Road Trailhead (45.605640, -122.823430)
  • Distance: 5.1 miles out and back with longer options
  • Elevation Gain: approximately 531 feet
  • Details: Limited parking at the trailhead which is a pullout on the side of the road. No restrooms are available. Roads to the trailhead are paved making access easy. This is the northern terminus of the 31.1-mile Wildwood trail.

It was raining hard right just a few minutes before I pulled up to the trailhead. The trees still glistened with fresh drops clinging to the tips of the branches. I found Susan and Henry just down the road a bit from where I parked, and we got started. A trail running event looked to be coming to an end as we arrived, and a table of volunteers welcomed us to the forest.

We took off at a moderate pace down the trail.  The green conifer forests promising some level of protection if the sky decided to open again.

What it takes

We started with introductions.

Henry introduced himself as a student, originally from Salt Lake City, in his first year in the Sports Product Design program at UO. His background is in electrical engineering.

“I heard about this program, and I was super excited about it,” said Henry, “I have a passion for hiking.”

Susan introduced herself as the professor and director of the sports product design program. Her background is in design, as well as human factors engineering and kinesiology. She earned her master’s degree at Cornell University under Susan Watkins, the mother of functional design, and from there entered the sports design space at the University of Minnesota, co-majoring in biomechanics and design.

“When I went to school, I was definitely an oddball student,” Susan laughed.

Susan (left) and Henry (right) after walking through some mud on the trail.

The Design Process

We continued along the well-worn path under the canopy of Douglas-fir and western redcedar. Sword fern dominated the understory along with a myriad of herbaceous forest plants, including vanilla leaf and yellow stream violet. 

As we hiked, I asked Susan for an overview of what she does as a sports product designer.

She began her explanation with a mission statement:

“Our mission is to push the field with game-changing solutions for athletes that push performance and society.” She continued, “we are looking at performance, but also in the sports industry, especially sports products, there is a large movement to look into equity in sport—and that is part of it as well.”

This is what sports product design—at least how she does it—aims for. But how does it get there?

“We use a design process that it similar to the scientific process,” entertained Susan.

As Susan explained, the process starts with a line of inquiry based on “how could we” or “how might we” statements—something akin to a hypothesis of sorts. From there ideation begins and the process of prototyping.

“Our program really values creating concepts and physical prototypes,” Susan expounded.

Once the prototypes are built, they are tested. This usually involves athletes or users trying the product and giving feedback.

Of course, just like in science, testing doesn’t always lead directly to the production and marketing of a product. Often the results of testing may require a step back or two. The design process is not linear. 

Product Testing

We soon crossed over a small wooden footbridge as we made our way further into the forest.

I asked Susan to elaborate more on the product testing side of things.

“There are infinite ways to test products,” Susan replied. “We could be testing for ease of use, regulation, impact protection, a feeling, accuracy… anything you can want an athlete to do, or have a better experience with, you can be testing for.”

On the practical side of things, the most common method used for testing is calling in a focus group. Asking people to experience the product and give feedback is the minimum expected for testing.

Then there are more complex methods using equipment, like thermistors or environmental chambers, for example.

Things get even more complicated if you are making a claim or in the business of making products that are more dangerous, like helmets. It is in these instances that, according to Susan, “testing becomes very important.”

“Companies have been shut down,” said Susan, “when testing wasn’t up to snuff.”

So, depending on the product, testing could take a long time, even years.

Hiking Shoes

At this point, we were beginning to encounter a good deal of mud on the trail. I could feel the traction of my hiking shoes failing as the slick clayey mud started to gum things up.

“What about hiking shoes?” I asked, “Let’s say you want to design hiking shoes.”

Susan was quick to admit that hiking shoes are not only a challenge for people to shop for but also a challenge to design. On top of that, there hasn’t been the level of effort put into hiking shoes as there has been for other products, like running shoes.

“Hiking is complicated,” said Susan, “because, like we are hiking on mud today which is different than hiking on something like snow or ice…”

In general, certain features should be considered to deal with the all-terrain use of hiking shoes, including traction performance, flexibility, water migration, waterproofness, and stability.

Methods for testing will often vary by company. Though there is some standard testing. A wear test—where a group of people wears and compares the product to a baseline is another possible method.  Wear tests can be as short as trying a product for an hour of exercise, for as long as a few weeks or even a month. Longer than that and designers can’t meet product timelines that very much rely on a season product launch cycle.

According to Susan, the sizing and fit of hiking shoes are also important to test.

Even though shoes are often built to a particular size model, the materials and how they respond to wear vary a lot.  Thicker material might make the size envelope a bit smaller.  Stretchy material may make it larger.

Duct Tape

We walked further down the trail.

Henry chimed in regarding his experience with product testing shoes. “It was interesting to see what they (the designers) were looking for,” he said.

One such “look for” were hot points and blisters—a common ailment among hikers, especially in certain conditions.

Susan told me about a time she did a hiking race on hot asphalt.  “My feet were burning!” She exclaimed. “I had to wrap them in duct tape.”

I told the group about a backpacking trip on sand that had a similar effect.

The good news?

“I learned duct tape is amazing,” said Susan.

I mean duct tape does fix everything. And in the design world what better tool can you turn to in a time of crisis?

“We aren’t afraid of duct tape,” Susan agreed.

Testing Woes

The weather continued to hold up as we walked along. Thought the mud only seemed to pick up. I told Susan and Henry we could go as far as they wanted.

“We won’t go 30 miles,” was Susan’s comical reply. These two were just plain fun to hike with.

Henry is not the only design student to be recruited for product testing.

“Companies know that they (her students) understand product,” confided Susan. “It is hard to get good product feedback,” she went on. 

If one thing is “wrong” with the product, often time feedback will come back negative, and the positive qualities of a product will be lost. Susan told me how countless times she has had testers come back with comments about the color of a product.

“I didn’t like the purple ones,” Susan mimicked a difficult tester. “It can be really polarizing.”

If even there is a more substantial complaint, like an uncomfortable high top on a boot, often all other feedback is lost on this one major complaint.

Research

Of course, before product testing, comes a different type of feedback—research.

“If the research isn’t there, then the design is completely invalid,” Henry confessed.

Research usually comes in the form of interviews with potential users and looking at existing products on the market. Science also supports and informs product design.

Henry shared a project he worked on designing a base layer for visually impaired skiers using haptic technology to communicate with their guides. He interviewed several visually impaired skiers to determine where best to place the haptics.

Research is imperfect though.

“Sometimes you will design something fully based on science,” said Susan, “but then someone will put it on, and it can nullify the invention.”

Looking uphill on the forested Wildwood Trail

Synergy

Soon we reached a large, upended tree—its roots sticking out at us onto the trail and a sticky, thick mud bath below. As we carefully picked our way around it, or in some cases slid our way, I asked Susan to tell me more about how science informs product design.

She laughed because in a lot of ways it doesn’t.

“There is a lot of research that happens in the lab that never gets applied,” said Susan. “In the pure sciences, you get a finding and move on.”

Pure sciences are often funded that way. Scientists are supported for the initial body of work—to answer a specific question. Once that knowledge is obtained the funding dries up.

However, at least at the University of Oregon, Susan is seeing a change—a shift to more collaboration between pure and applied science that seems to really be paying off.

Susan is part of the Wu Tsai Alliance—a group comprised of scientists from a variety of backgrounds with the common goal of understanding human performance.

“The group formed last year, but we are already seeing the synergies,” said Susan. “For example, a biomedical engineer designed and sensor, and one of my students is taking the sensor and putting it into footwear for their thesis project,” she elaborated.

Fighting for Women

Like the obstacles to collaboration, the Wildwood trail continued to throw log hops in our way. As we clambered over another one, I asked Susan to share a bit about the projects she is involved in.

“I have my fingers in a lot of different things,” was her unsurprising response. She didn’t seem the type to take life sitting down.

“I am finishing some research on size and fit issues for women firefighters,” Susan shared one of her projects.

“Gear for women isn’t really designed for women,” she explained. As a result, women firefighters are getting hurt. A fact that has been known for over a decade but hasn’t been acted on until now.

Susan hopes to change all that by identifying important knowledge gaps.

As a next step, she is also working with another scientist that does machine learning to analyze 3-dimensional body scans of athletes.  The goal is to understand geometries beyond the basic chest-waist-hip measurements and interpret findings into better product performance.

Runners High

Susan is also using machine learning and body scans to better understand women’s running. She plans to survey thousands of runners and pair that data with scans to look for unknown patterns that relate to running performance. She hopes to tease out what is talked about in the common press when it comes to performance—to identify what works and what is just hype.

Innovate

At this point, Susan, Henry, and I reached a trail sign near a fire lane. Having gone a few miles, we decided to turn around. Thankfully the rain continued to hold off as we retraced our steps back.

Then I asked Henry, what he wanted to do with his career. His answer boiled down to one word—innovate.

“In our field, there is true athletic product innovation,” said Susan.

However, the focus of that innovation has shifted over the years, leaving many sports neglected. According to Susan, outdoor sports, like skiing and climbing, are ripe for innovation.

Hiking is another one.

“Running shoes are designed for environmental and biomechanical needs,” Susan explained. “Hiking shoes haven’t really gotten there yet….that is why people go to trail running shoes.”

Environmental Wear

Another area ripe for innovation is waterproofing.

Though there are some products that work better than others, waterproofing than be challenging. For one, it doesn’t last. And secondly, the chemistry is bad for the environment.

“It is part of the Teflon family of chemicals,” said Susan.

So, companies turn to more environmentally friendly alternatives, but at a cost—a loss in product quality.

Walking through a beautiful green Douglas-fir Forest, it is hard not to want to protect it. So, I asked Susan, how we are doing in the sports industry with making environmentally safe products?

“We are not doing well,” was her blunt response. As the sports product industry shifted from cotton and wool materials to synthetics in the 1960s and 1970s, sustainability went out the window.

“It is concerning when you learn more about it,” said Henry.

However, there is some hope for the future. According to Susan, natural fiber companies are working on innovating to create more biobased products.

In addition, there has been an uptick in transparency regarding the sustainability of products. For example, Marmot now ranks products for their sustainability versus performance.

“Companies are going to be held accountable, “Susan commented. She mentioned a panel she was on in Europe where there was a discussion on taxing people for purchasing unsustainable products. “I think we may see things like that in the future,” she continued.

Recycle, Reduce, Reuse

A few other ways companies are combating the issues of sustainability and durability are through the reuse and recycling of products. Companies like Patagonia will buy back products and repair them for resale. Other companies will recycle products to make something new.

Repair is another major movement. Susan mentioned Fjallraven in Portland’s Pearl District providing repair and waxing stations for waterproofing.

Keep it Simple

We continued working our way back to our cars, climbing the logs and sliding over the same mud slicks we encountered on our way in.  As we were nearing the trailhead, I asked Susan and Henry for some consumer tips for buying products.

“For me, it is not to overdo it,” said Susan. She recommended choosing clothing that is comfortable, fits well, and allows for mobility. It isn’t necessary to have high-tech gear on a day hike. Even jeans may be acceptable in most conditions.

“There is a lot of discussion around equity in sport,” Susan said, “especially hiking.” According to Susan, people see it as a “white sport” and only for the “affluent,” but hiking is for everyone.

By keeping things simple, she hopes more people will see themselves on the trail. 

Wear and Tear

Another tip Susan emphasized was wear.

“If you haven’t fully worn in something, you can have a really bad experience,” said Susan.

“Your body changes when you are hiking,” she continued. “Feet and hands can swell, for example.”

Taking the time to try out gear in a low stakes environment and wear it in is key to an enjoyable outdoor experience.

Luckily, some companies are creating return policies that allow consumers to really try out products before they fully commit to purchasing.

Functional Innovation

Innovative products that improve functionality is something else to look out for and consider when purchasing items.

Susan mentioned innovation in hydration as another example. Camelback and other bladder systems allow for a hands-free experience, while filters allow for longer and safer outdoor experiences. Both innovations have revolutionized outdoor sports.

Even something as simple as having the right size or style of pockets can make or break a product.

Keep Improving

As we neared the trailhead, I asked Susan one more question—Why does sports design matter?

According to Susan, sports product design is about maximizing human potential. It is also about the benefits of engaging in sport –  like health and happiness, available to everyone.

“There are an infinite number of problems to solve,” said Susan, referring to the sports product industry.

Fortunately, the process of product design is iterative. And with new tools for design, products are improving.

Body scanning and machine learning are changing how products can be made. It may be that mass production changes in the future and more personalized sizing will become available to everyone.

“The tech is already there,” Susan remarked. “I know scientists that can look at your Facebook picture and tell what your body scan looks like.”

Hike Happy

In the meantime, consumers and hikers have a lot of options to choose from when it comes to sports product design. There are still some problems to solve. But, by keeping it simple and choosing products that function and wear well, you can still enjoy the benefits.

So, take a hike through the woods. Climb a mountain if you will. Paddle or float. Whatever sport you engage in, keep it simple and wear what works for you.

Perhaps Henry’s advice is most apt and to the point: “You got to wear what makes you happy.”

Hike at McCully Mountain with a Wildlife Biologist

View of the McCully Mountain meadows

Open prairie grasslands, hummocky wet meadows, meandering rivers, and magnificent branching oak woodlands—before European settlement, Oregon’s Willamette Valley was a very different place. A place blackened by fire and awash in waves of wildflowers. A sea of purple camas covered the hillsides, along with irises, cat’s ear lily, golden paintbrush, and more. Grand Oregon white oaks, with their spreading branches, grew singly or in woodland patches, completing the look.

Now, very little of these habitats remain in the Willamette Valley—lost to human development. It is a place dug up by plows and awash in pavement. A sea of houses covers the hillsides with agricultural fields everywhere in-between.

In recent years, as scarcity has increased, oak habitats in Oregon have been given more attention. Even sites on the edge of the valley are being considered for restoration by conservation groups and land management agencies.

McCully Mountain, just east of Salem, is one such site. A parcel of BLM land with a bit of oak on a wet meadow surrounded by private lands, and in need of a little elbow grease. 

So, with the help of volunteers and other staff, Corbin Murphy, BLM wildlife biologist, has been working for the last few years to restore the parcel. Or as he put it, “create some habitat on the landscape.”

I met with Corbin on a wet spring day to take a look at the progress. 

The Hike

  • Trailhead: No official trailhead.
  • Distance: varies
  • Details: Park at the pullout on East McCully Mountain Road. No trailhead or signage. There are no amenities at this site.

Classic BLM

Corbin and I carpooled out to the McCully site along some backcountry roads, before reaching a small pullout. A faint trail led us through a Douglas-fir Forest a short distance.

“This is kind of classic BLM,” said Corbin. In other words, a parcel of public land, abutted by private lands.

You see, in the late 1800s, as part of a settlement plan for the west, the federal government granted every other square mile swatch of land to the Oregon and California Railroad Company to fund the building of public transportation through the state, the other half was to be sold and distributed to settlers.

Unfortunately, fraudulent sales led to the reinvestment of the O&C lands where they were put under the jurisdiction of the U.S. Department of the Interior, General land Office (GLO). Today these lands are now managed by the Bureau of Land Management (BLM).

The problem is this “checkerboard pattern” of land ownership is a “nightmare for management.” Though there has been some consolidation of ownership, public and private lands still share extensive boundaries.

“Access and road problems are reoccurring,” Corbin explained. And McCully is no exception. “Folks can walk down the spur road to get to the BLM, it is public access,” despite warnings from signs posted on the gate.

ACEC

Eventually, the conifer forest peters out along a grassy ridge with views onto the surrounding hillside.

“This is the property line right here,” said Corbin.

Oregon white oak grow in huddled bunches along the ridge—mostly smaller trees trying to get a foothold. A soggy meadow lays quietly below.

“For the BLM this is one of our Areas of Critical Environmental Concern—an ACEC,” said Corbin. As such, McCully receives special management attention to protect its natural resources.

ACECs are established for a variety of reasons. Some are established for geology; others for their cultural or scenic value; and others for habitat, for example.

McCully was designated an ACEC for its scenic value, natural systems, and wildlife value.

“Special habs,” as Corbin put it—McCully is “not just some conifer forest… it is 80 acres of oak meadow.”

Views from the grassy ridge at McCully Mountain

Inverts

As we continued down the ridge, Corbin and I were cognizant of the wildlife all around us.

A Northern pigmy owl called out in the distance. Deer and elk scat lay in darkened clumps on the bed of green grasses and herbaceous plants at our feet. I nearly trip over a mountain beaver burrow entry hidden on the ground.

However, it was the smaller, less conspicuous critters that Corbin is really jazzed about.

“There has been a lot of work on megafauna, and especially rare species,” Corbin explained, “but there are a lot of critters that are new to science and not studied. A lot of these are inverts.”

Invertebrates—animals without a backbone, like insects, spiders, and worms—play many important ecological roles. Many are pollinators; others are decomposers, for example. And all are key parts of food webs—supporting vertebrate species, like birds.

Thus, studying invertebrates can tell us a lot about the functioning of an ecosystem.

Moths

One group of invertebrates that hasn’t recieved a lot of attention are the moths. Which is why Corbin was thrilled to have McCully Peak included in a moth study organized by researchers at Oregon State’s Arthropod Collection.

The study was intensive with survey data collected every two weeks from light traps set up at four different points acrooss the meadow.

“Guess how many species we found?” asked Corbin, a twinkle in his eye.

“I don’t know, twenty,” I guessed reluctantly.

“Two hundred!” Corbin exclaimed. “And a bunch were for the first time documented in this county in Oregon,” he went on gleefully.

Of course, these results were collected before restoration work got underway.

“We will come back and do some post-treatment monitoring,” Corbin assured me.

Competition

Corbin and I continued to circle the forested meadow’s edge. Douglas-fir logs lay abandoned near their stumps along the ridge. Other conifers have been girdled—a strip of bark removed in a ring around their trunks.

“The down wood and snags are important for wildlife,” Corbin explains. Offering habitat for many species, including many of Corbin’s beloved invertebrates.

Perhaps even more importantly, Oregon white oaks are slow-growing species and can easily be shaded out by fast-growing conifers. So, a big part of oak restoration involves getting rid of the competition—in this case, Douglas-fir. But rather than simply harvesting the Douglas-fir trees and hauling them off, the trees are left in place to decay.

Corbin was also quick to note that, though the Douglas-fir have a foothold now, the shallow soils in the meadows make it difficult for the trees to succeed long term.

“Many are dying,” Corbin points out, but while they live, they make it more difficult for the oak.

Down logs and girdled Douglas-fir trees

Invasive Species

In addition to competing with conifers, oak habitats face encroachment from alien invaders—a.k.a. invasive species.

“This was all ringed with scotch broom,” Corbin shared as we cut along the meadow’s edge, dodging poison oak as we went. Shiny geranium, another invasive species, grew in large uniform patches at our feet.

“We pulled and cut all the scotch broom about 2 years ago,” said Corbin.

As Corbin and I headed down the hillside, we spotted a few new scotch broom sprouts. When it comes to invasive species, the work never really ends.

“It is going to be a constant battle,” resigned Corbin.

Volunteers

A lot of the restoration work, including removing invasive species, was done by volunteers using clippers and machetes.  At McCully, several volunteer groups came out to help with the restoration work, including Northwest Youth Corps and Linn County Juvenile corrections, as well as a group from Backcountry Hunters and Anglers.

Volunteers also helped with basketing oaks—encircling young oak with netting to protect against browse.

“Deer are funny,” Corbin chuckled, “they love oak.”  At one point, Corbin pointed out an oak that had been heavily browsed—nary a leaf could be seen.

Thanks to volunteers, more of the oaks can escape these pressures and have a chance to make it to maturity.

“I do love the opportunity to get the volunteers out,”  said Corbin. “Something like this is really fun too,” he went on.

Corbin reminisced about the time the Backcountry Hunters and Anglers visited. Elk ran through the meadow and they saw a ton of wild turkey.

“We are coming back!” they told Corbin after a long day of volunteering.

“Good! This is your public lands, enjoy it!” was Corbin’s reply.

Suspected Species

The sky is gray, threatening rain. Corbin and I continued past more young oak and patches of scotch broom toward the meadow below. 

Tracking down the hill, we followed a wide muddy path littered with deer and elk hoof impressions.

At the bottom of the hill is a wet meadow where yellow monkey flower grows in a wet seep. Fist-sized rocks lay scattered on the meadow that has been heavily grazed. The vegetation is clipped close to the ground in most areas. The scenery is beautiful, and wildlife clearly abundant.

Transfixed by the open, rocky expanse, I asked Corbin what sort of wildlife might use the space?

Well apart from the usual deer, elk, and other generalist species, Corbin mentioned several “suspected” species that he is hoping to find in the space. Streaked Horned Lark and Fender’s Blue butterflies, for instance—are two species associated with oak prairie in the Willamette Valley.

“We say ‘suspected,’” said Corbin, “If it is within the range and habitat requirements are all there.”

Boulder-strewn meadow

Desert Life

Another suspected species Corbin is excited about finding is the pallid bat.

“The pallid bat is a desert species that used to exist in the Willamette Valley,” explained Corbin. Other desert species, like ponderosa pine, jackrabbits, Northern Pacific rattlesnake, and burrowing owls were also once present in the Valley. But, like the pallid ba, these have all but been eliminated.

According to Corbin, the pallid bat is unique from other bats in that they don’t typically use echolocation but forage for ground-dwelling insects, like scorpions by sound. This can make them trickier to identify in the wild using passive acoustic recording units since they are not making ultrasonic calls to locate food.

“This is part of its historic range,” Corbin noted, so they could be here, or move here, even if they haven’t been identified yet.

Woodpeckers

The rhythmic thumping of a Northern Flicker sounded against the high-pitched songs of other bird species as we continued toward the forested edge of the meadow.

“What about woodpeckers?” I asked.

“It should be a feeding frenzy,” said Corbin, looking out on all the girdled conifers. “There are a lot of downy and hair woodpeckers, flickers, and pileated woodpeckers.”

Woodpeckers forage in dead and decaying trees, making the wooded edges of the meadow with newly developing snags, a great place to feast.

Lewis’s Woodpecker is another suspected species for the area, though none have been spotted yet. They were once widespread however due to habitat loss of mostly snags in oak, pine, and cottonwood woodlands their numbers are low. However, for all these species, Corbin is hopeful.

“If we create the habitat, they will come,” he tells me.

Making Habitat

Dark clouds continued to gather, as Corbin and I walked adjacent to the forest, looking up at more girdled conifers. Corbin admitted that girdling is not the ideal way to create snags but it is quicker and cheaper than topping them.

“It is expensive to top them,” he said, but “it creates an opportunity for spores to land on top and heart rot to enter.”

Ultimately, cavities form, making the tree not only an excellent foraging site for woodpeckers but useful for nesting as well.

Legacy Tree

Soon a large snag came into view. This was no restoration project tree—it’s open-top reached toward the sky.

“That is what we call a legacy tree,” said Corbin. “It was probably part of a previous cohort,” he speculated. “A stand-replacing fire came through and that was the only one that lived.”

Snags are excellent habitat for many species. Legacy trees are even more exceptional. Their large girth can support species that depend on a larger diameter tree.

“Those are great for bats,” Corbin exclaimed. “We have another bat that is out here,” he went on, “the fringed myotis.” Named for the fringes of hairs that can be found between their back legs.

“It loves snags,” said Corbin. “It roosts in the sloughing bark,” he continued.

However, in this case, size does matter. They need a larger diameter snag—”61 inches on average,” according to Corbin for roosting. “It is one of the limiting factors for fringed myotis.”

Large Down Wood

The life or death, as it were, of a legacy tree does not end there. When snags eventually fall to the ground, they continue to support species dependent on larger trees for survival. For example, Oregon slender salamander, an endemic to the Cascades, has only been found in large down wood.

Corbin expressed concern about these species. “Maybe around the turn of the century there were really big trees,” but… “fast forward and much of our forests are on a 30-to-40-year rotation.”

Large trees begat large snags begat large down wood. If we don’t have enough large trees, where does that leave us?

So, perhaps it is not surprising that Corbin called legacy trees “gems on the landscape.” They are both valuable and rare.

Legacy tree

Intersection

We continued to follow the forest down to the property line, where BLM land abuts private. As we reached the fence, we could see another clear cut could be seen through the trees.

“Well, I guess there is more meadow now,” Corbin smirked.

A turkey sounded in the distance. Surprisingly, Corbin called back. The turkey gave no response. It remained silent, even after I gave a half-hearted gobble-gobble.

We passed a girdled tree that had fallen over. A few purple calypso orchids grew near its base. Then a bit later, Corbin spotted invasive mullein that gave him pause.

Eventually, we began to edge our way back through the meadow at the back end of the property. It was at this point, that it began to shower.

We had reached a point of intersection—between forest and meadow, public and private, and wet and dry—a confluence in more ways than one.

“Anytime you have the confluence of conifer forest, oak woodland, and prairie,” Corbin stated, “that is where you are getting cover, forage, and nesting opportunity.”

That is where you find wildlife.

Secret Garden

We soldiered on over the soft hummocks of grass and herbaceous plants. Rocky outcroppings and undulating hills gave the walk dimension. Prairie stars and rosy plectritis also made an appearance in these lower meadows.

 “There is a lot of BLM ground like that that people just never really get to,” Corbin remarked as we passed by a patch of popcorn flower. “A fun part of my job is getting to explore these areas.”

This certainly rang true for McCully. There was no one around but us… and the deer.

Looking up from the lower meadows

Boundaries

As the rain picked up, Corbin and I decided to turn and loop back up to our vehicles. Corbin led the way—following the path of least resistance and least poison oak.

I was really starting to feel an affinity for the place—wildflowers have a way of doing that to me. Inspired by the unique landscape, I wondered just how much land BLM has designated as areas of critical environmental concern (ACEC). So, I asked Corbin.

“It is hard to tell,” he responded, “different field offices have different amounts of ACEC.”

For the Cascades field office, running from the Columbia River Gorge to Sweet Home, where Corbin works, he estimated a figure—“there are roughly fifteen thousand acres out of one-hundred-seventy thousand acres, about 8 percent in the Cascades Field office and about 2 percent across Western Oregon BLM.”

In short—there is not a lot.

Each ACEC is specifically delineated to encompass just the small area of land that contains a unique feature, like a rock garden or bog. ACECs are by definition scarce. Anything that isn’t unique makes up BLM timber reserves, some of which are open to timber sales and sustainably harvested.  

Heading Home

We continued up the hill, passing by deer beds… “1, 2, 3, 4, 5…” Corbin counted as we walked by. We followed a creek bed that looked more like a slip and slide where you could see just how shallow the soil was above the exposed bedrock.

“Not even a couple of inches of soil on that,” Corbin exclaimed.

Eventually, we re-entered the familiar forest that we had walked through at the beginning of our hike—back into the ordinary.

Looking back through the trees at the oak meadow, it appeared almost magic against the grey sky—a secret tucked away in the west hills of the Cascades.

But McCully Peak isn’t a secret. It is one of many unique places scattered throughout our public lands—welcoming a visit.

Corbin Murphy is a Wildlife Biologist for the Salem District of Bureau of Land Management. He has been with the BLM for 13 years and currently works in the Cascades Field Office. He has also worked for the U.S. Forest Service.

Hike with a Bee Scientist

Creek running through Kingston Prairie

Nothing heralds spring and summer better than the vibrating hum of bees on the wing. Bees are a group of winged insects probably best known for their role as pollinators. We praise bees for their important role in our food systems. We depend on them.

However, if you ask Andony Melathopoulos, coordinator for Oregon Bee Project and OSU Pollinator Health Extension Specialist, there is more to bees than pollination.

There are estimated to be about 700 different species of bees in Oregon, each one with a unique life history. There are solitary bees and social bees; bees that nest in trees or on the ground; bees that are very reluctant to sting and those that will get you crying to your mother—the diversity is incredible. So incredible, in fact, that it has inspired a statewide movement to document all of Oregon’s bees.

The Bee Atlas program is a community science effort to inventory Oregon’s native bees, track populations, and educate Oregonians about bee biodiversity. Andony is part of that effort—helping coordinate events, including Bee School for those interested in becoming part of the project.

I met Andony at Kingston Prairie Preserve just outside of Stayton to go on a bee hunt and learn more about his work around bees. 

Preserve

It was late afternoon when I arrived just ahead of Andony and wandered out onto the mounds of soft wet soil. The ground was patchy with wildflowers and shrubs growing among the hummocks of grass.  A small babbling creek ran across the nearly flat open terrain. I walked tentatively toward the creek to look around before circling back, as there is no trail system at Kingston Prairie Preserve.

Soon Andony pulled up and we continued our journey deeper into the preserve together.

“This is my favorite one,” Andony stated, referring to the collection of properties managed by Green Belt Land Trust, a conservation non-profit based in Corvallis.

Though we missed peak bloom, the prairie was still quite beautiful in the afternoon light. We walked by some purple camas and shooting stars. Tall white saxifrage and yellow monkeyflower were also in bloom. 

A sign and wire fence marks the location of the Kingston Prairie Preserve

Honey, Honey

“I’ve worked with bees my entire professional life,” Andony told me, by way of an introduction. “I worked for years on one species of bee—the honey bee.”

Most people know honey bees. Veracious pollinators and producers of honey—their small fuzzy black and amber striped bodies are well recognized. You might call them celebrities of the bee world. (I mean there are at least a couple of movies made about them—I’m looking at you Bee Movie.)

Though fascinating creatures, Andony’s love for honey bees primarily stems from the community of people that work with honey bees. In college, he got involved in beekeeper organizations and really enjoyed it.

This hive mentality has carried him forward to his work now with the Oregon Bee Atlas. Seeing other groups, like native plant societies, motivated him to do the same for bees.

“It gave me the impetus to have people constantly tugging at me,” Andony remarked, “Asking questions…’ what is this?’ Is it weird?’”

Honey bees remain Andony’s favorite bee to date. Oddly, the first bee we saw on our hunt was a small honey bee.

“Hey, what are you doing here?” asked Andony, as it flew off.

Our State is the Best

Andony and I followed the creek, looking for interesting flowers and bees that might be visiting them. As mentioned earlier, there are a lot of species of bees in Oregon.

“We think we have about 700 species,” said Andony. As a comparison, “there are only about 500 species east of the Mississippi.”

Of course, this begs the question—why?

Andony highlighted two main reasons for bee biodiversity in the state.

One: geographic zones. Oregon has a lot of geographic zones with unique climatic characteristics. From the wet coastal regions to mountains to high deserts—the ecology varies border to border. Because of this, flower and bee species have radiated—evolved to fit each climatic zone.

Two: desert bees. Much of Oregon’s bee diversity is owed to the diversity of bees that survived the last ice age in Mesoamerica.  These desert-loving bees traveled North as conditions warmed providing an input of biodiversity into the region.

“Bees love the desert,” said Andony.

Not a Bee

At this point, we had not had much luck finding any bees. Maybe it was already getting too cool out. Bees tend to be more active when temperatures are warm.  Whatever the case, Andony and I decided to look for a place to hop over the creek.

Before we made the hop, I saw something moving among the flowers.

“A hoverfly,” stated Andony. “Lots of people mix up flies and bees.”

Standing there, I was pretty sure I was one of those people.

“How can you tell them apart?” I asked

“Both are insects,” he began, and “Most insects have two pairs of wings. The difference is that a fly’s second pair of wings have been reduced to what is called a halter—a little gyroscope that allows it to suspend itself in midair.”

In other words, flies hover.

Flies can also be carnivorous or parasitic, feeding on other insects. Bees on the other hand are unique in that they get all their protein from pollen.

Shortly, another fly hovered by saxifrage. Not a bee.

Then out of the corner of my eye—more movement. Andony got out his net and swoop, he caught whatever had flown by.

“Looks like some parasitic wasp,” said Andony, getting a better look. “Its antennae are very low and vibrating—looking for prey.” They, like flies, rely on other insects as a protein source. 

According to Andony bees are actually specialized wasps. While wasps paralyze and store prey in holes in the ground, bees do the same but with balls of pollen.

Wasps can also be distinguished from bees by their form.

“They have a tight waist between the thorax and abdomen,” described Andony. Not a bee.

Andony put the wasp on ice in hopes that we could get a picture of it later. It flew away before I could get the shot.

A curious fly hovered around the saxifrage. Fly not pictured.

Long-horned on Ice

“This place is like a gas station,” said Andony, as we watched everything, but bees fly by. “There are a lot of things that like nectar.”

Then, out of the corner of his eye, Andony spotted a small flying insect alight on a geranium. And with a quick flick of the wrist, he had the insect in his net.

“You’ve got yourself a male spring long-horned bee!” he exclaimed. “You will love it!”

Long-horned bees are known for their long antennae—hence the name. Male long-horned have extra-long antennae and a “little yellow nose.”

According to Andony, male bees in general have an extra antennae segment—which is helpful for sex identification. And as male bees do not have stingers, this information can be valuable for someone who studies bees for a living. Most long-horned bee species emerge in the summer.

“It is always on a sunflower,” Andony mused.

Our fuzzy friend was an early spring species. We carefully put him in a makeshift cooler to slow him down for a photo. This time we were successful!

It’s all about the Plants

Andony and I continued scanning the prairie in the hopes of finding more bees.

“I like the color over there,” said Andony pointing towards a cluster of wildflowers nearby.

And that is just it, isn’t it? Flowers. Flowers are the key to finding bees, so I asked Andony what sort of flowers bees prefer?

The answer turned out to be more complicated than I imagined.

First, “You find the strangest and weirdest bees in the weirdest plant communities,” Andony said. In places like “the Siskiyou’s, Steens, Alvord desert, and Wallowa’s.”

“All the cool places,” I remarked.

“Any cool place in the state,” Andony agreed. Where the plants are weird so are the bees.

Specialists

Second, “Bees specialize,” said Andony.

As plants evolved with greater complexity some 100 million years ago, bee evolution also took off.

“Bees are in competition,” Andony explained. Competition with each other for pollen.

Specializing for a specific flower or group of flowers, reduced competition by giving a bee specialist a leg up.

“The one plant I was really hoping would be in bloom popcorn flowers,” Andony mentioned wistfully, “They have a number of really specialist bees in them.”

Third, not all bees are specialists. Many are generalists, like honey bees and bumble bees, and are happy to eat pollen from many different sources.

“Bumble bees like monkeyflower,” said Andony, but they also like a whole host of other plants. No monkeyflower around? No problem. How about some lavender?

So, when it comes to flower preferences, it really depends on the natural history of the bee.  A rare bee will only be in a rare environment on a rare flower, but a generalist bee will be attracted to many different flowers.

Abundant monkeyflowers growing along the creek

Gardening for Bees

Andony did offer some general tips, however, for attracting bees to the home garden.

“If I was going to snazz up my garden. I would definitely go for anything in the composite family,” he remarked. “Black-eyed Susan, echinacea, and also golden rod,” Andony suggested, “Golden rod is one that I really love… and it attracts a lot of bees.”

Other plants Andony mentioned during our walk are Oregon Grape, sunflowers, and lavender.

Cinderella Bee

Andony and I continued to meander along the creek until we found a good place to cross. We made the leap across the small divide, landing with a thud on the soft earth.

As we walked amongst the tall grasses and shrubs, I asked Andony what else bees require, besides flowers?

“They nest in a lot of ways,” said Andony—some nest in the ground, others in trees or other woody plants, and some build their nests, for example. Others still will take up “rent” in already formed nests.

One nest-building tale is that of the small carpenter bee.

Andony began, “Here is a pithy stem,” grabbing at a nearby plant and holding the stem up for inspection. “It if was later in the year, you might see some holes in the end here.”

Carpenter bees will take the pith and grind it up into sawdust, hollowing out the stem and creating a chamber. Once complete, they will crawl into the chamber, mound up some pollen inside and lay an egg. They will then use the sawdust to create a partition and repeat.

Here is where the story turns into a Brother’s Grimm fairytale.

“They have Cinderella daughters,” Andony states. “The first offspring they raise, they don’t feed very much.” He paused for dramatic effect. “But what she can do is block the door with her head.”

Again, one of the strategies bees, wasps, flies, and other insects employ is to use the nest of others to lay their eggs.

Cinderella is there to protect the nest from these intruders, ensuring her brothers’ and sisters’ survival at her own expense.

Community Science

Andony led the way, as we continued to wander the meadows looking for bees, but we weren’t having any luck. After a few starts and stops, we leaped back across the creek in search of some more suitable shrubs and trees.

Even though we weren’t finding many bees today, clearly there are a lot of bees out there. In 2019, 25,022 specimens were submitted to the Oregon Bee Atlas, raising unique species estimates to 650.

“About 190 volunteers contribute to the Atlas,” said Andony. And they are just getting started.

“It is ongoing,” Andony explained, “There is so much environmental change. It is a dynamic process.”

Anyone interested in volunteering for Bee Atlas must first complete the Master Melittologist program offered by OSU extension. The program includes online training, a field course, microscope training, and group collection outings.

“Then they become someone that can enter data for the state,” said Andony.

Of course, to get to the next level, the Journey level, requires a test.

“You get a box of bees and must identify to genus, and for bumble bees to species,” Andony described. There are 25 or so species of bumble bee.

I would most definitely fail that test. 

Getting Hooked

Still struggling to capture any new bee species, we beelined it over to a flowering tree on the other side of the property. It was a beautiful serviceberry tree, or Saskatoon, with the white petals of the flower open and welcoming. The area was a hum with activity—though most of it unreachable above our heads.

As we watched various insects cruise by, Andony told me how we got hooked on bees, and why others might care too.

Of course, the easy answer as to why we feel we should care about bees, according to Andony is that they help feed us. “Agricultural food systems depend on pollinators,” and what are bees if not excellent pollinators.

But pollination isn’t a complete answer. In fact, most of our native bees do not contribute to food production.

For Andony bees are about more than the services they provide. His love for bees stems from just how cool they are.

“They have crazy, weird natural histories,” he gushed— “there are bees that are cuckoos on other bees, specialists on certain plants, iridescent green bees, jet black bees, bees that build little tunnels…and bees that stay in diapause and may not emerge during a drought year.”

Then of course there is the “complicated, fascinating interplay between regions, flora, and bee genera.”

What is there not to love?

“I think most people love things first but are bashful about it, and need to try to justify their feelings,” said Andony. Hence, the need to find an “easy answer.”

Andony argues that the first feeling of love is all the justification anyone needs and hopes to encourage others to follow their passion as he has.

The Bee Atlas and Master Mellitologist program are his way of giving structure to those that love bees and want to really get to know them. He hopes to provide just enough guidance to “ignite their curiosity.”

Getting to Know you

After lingering for a while at the serviceberry tree, we decided to make our way back toward the entrance to the preserve.

As we walked, I asked Andony for a list of beginner bees. I was going to need a lot of structure, indeed!

Here is what he suggested:

  1. The honey bee (Apis mellifera – 1 species). Fuzzy, with tan banding, they are easy to pick out. Most people are sort of familiar with honey bees, so it is a good place to start.
  2. The bumble bee (Bombus spp – 25 species). Also, distinct—their large girth and extra hairiness are a dead giveaway. Bumble bees are also a lot of fun to observe because you can track them through the season. In early spring, queen bees hover over the ground looking for a nest. A bit later, tiny worker bees emerge to forage. Finally, the males are kicked out of the hive and left to roam the countryside. Look for them on Lavender where they often congregate.
  3.  Longhorn bees (Eucera spp – spring longhorn ~ 10 species; Melissoides spp. – summer longhorn ~ 40 species). With their extra-long antennae, perhaps among the cutest groups of bees. Look for summer longhorn species on sunflowers.
  4. Small carpenter bees (Ceratina spp. ~ 5 species). Andony describes them as “little ants with wings.” Small carpenter bees can be found nesting in raspberry cane and spirea.  
  5. And finally, mason bees (Osmia spp. ~ 75 species). Mason bees are in a family of their own. Besides their often dark or metallic color, mason bees can be distinguished from other bees by the way they carry pollen on their bellies and nest in holes in the ground. Look for mason bees on Oregon grape.

And with that, “You got the bare surface of bee biodiversity in your mind,” Andony proclaimed.

If that isn’t enough, Andony also recommended the book, Bees in your Backyard by Joseph Wilson and Olivia Messenger-Carril. Go ahead and feed your bee obsession.

Bee are Family

We didn’t catch any more bees that day. The sun was dropping too low, and the energy of the afternoon was waning. But I found myself far from disappointed as I headed for home.

Andony had invited me into his hive—shared his passion for his work. It was invigorating and just plain fun.

There are five bee families in the state of Oregon—Andony shared this fact with me as our visit was ending. But he was forgetting one—a family of people that love bees and have put in the time and study to observe them.

One of the things that Andony really emphasized during our visit is the value of the bee-person community.

“The thing that I love the most about bees…” started Andony… “the people.”

Andony Melathopoulos is a coordinator for Oregon Bee Project and OSU Pollinator Health Extension Specialist. He also hosts a weekly podcast called PolliNation.

Hike with a Marine Ecologist

Ocean breakers offshore at South Beach State Park

There is something mythical about whales. Stories of whales show up repeatedly in folklore—represented as otherworldly and wise. Whales live in a different realm— mammals like us, whales breathe air, but somehow make a living in the Ocean. Their lives are cloaked in mystery—behaving in ways we are only beginning to understand.

One person who is trying to unlock their secrets is Leigh Torres, principal investigator of The Geospatial Ecology of Marine Megafauna Laboratory at OSU’s Marine Mammal Institute. So, on an exceptionally warm day in winter, we met up at South Beach State Park to hike and talk whales.

Her dog, Pepper, in tow, we headed out along the path that follows the south jetty out to the Pacific. The sky was bright blue overhead. Hordes of people were out enjoying the sunshine.

The Hike

  • Trailhead: Yaquina Bay South Jetty Trailhead.
  • Distance: Approximately 1 mile for beach walk. Additional options available.
  • Elevation: Minimal
  • Details: Plenty of paved parking at trailhead. No fee for parking. Pit toilet at trailhead. Follow a gravel trail that parallels the jetty over the sandy dunes to get to the beach.

Finding a Passion

As we walked, I asked Leigh to tell me a bit about her background.

“I grew up loving animals,” Leigh responded, “especially big animals.” Admittedly a common interest of many kids.

That, coupled with a childhood growing up in Miami connected to the ocean, and her love for science, the stage was set.

So, though Leigh began her studies at American University as a soccer player and photography major, it didn’t take long for her path to take a bit of a U-turn. Through a study abroad in Australia working with marine mammals, she found her passion for marine research. “I want to do that,” she recalled thinking at the time.

Leigh ended up double-majoring in photography and environmental science before pursuing advanced degrees at Duke University. There, she began her work with marine mammals studying dolphin behavior and foraging.

Now she is a marine ecologist at OSU studying the spatial and behavioral ecology of marine megafauna—how they behave, where they go, etc.

As we walked up next to the dark rocks of the south jetty, Leigh pointed out a couple of heavy orange-billed rhinoceros auklets swimming in the navigation channel. We could also see the dark rounded heads of sea lions bobbing above the water.

“Well, there is a couple of marine mammals right there!” she exclaimed.

Looking out into the navigation channel as we headed to the beach.

Whale Habitat

Continuing over the foredune and onto the ocean beach, the sights, and sounds of breaking waves immediately captivate the senses. Here, Leigh and I got down to the business of talking whales—specifically gray whales.

“We are actually looking at one of their main habitats,” Leigh began as she pointed out toward the breakers.  The Newport coastline is a major feeding ground for a group of resident whales that stop here to feed during the summer and fall months, rather than migrating further north to the arctic.

“They feed close to shore,” said Leigh, “They feed on really shallow reefs often covered in kelp.” These areas are highly productive habitats—hosting many species that whales need to survive. In particular, mysid—shrimp-like zooplankton—swarm these areas, providing a staple food source for gray whales to dine on.

Squinting out toward the white-capped waves—I tried to imagine what lay below the surface, an entire rocky ecosystem with thick green kelp beds, fish, invertebrates, urchins, starfish, and, of course, whales. All of which depend on each other to maintain a healthy system.

Walking down off the foredune onto the beach.

Feeding

How gray whales feed is something else entirely!

As we walked along Leigh told me how gray whales use a variety of foraging tactics to feed, including “head standing”, “sucking benthos”, and something called “bubble blast.”

What? Bubble blast? I asked Leigh how this works.

She explained that the whales will blast bubbles through their blowhole underwater to create a cloud of bubbles a couple of meters wide. They will then chomp their jaws near the blast to feed.

“Bubble blast is a mystery,” Leigh proclaimed. No one knows why they do it. Leigh speculated that it could be related to buoyancy.  Whatever the reason, these foraging strategies seem to be culturally shared.

Leigh laughed as she recalled some bubble blast footage her lab caught on tape of an older, 30-year-old male whale named, Peak, feeding with a younger 7-year-old male, Pacman on a reef. Peak bubble blasted and Pacman followed suit. Just two peas in a whale pod.

According to Leigh, this feeding time is vital, especially for females.  “They are capital breeders,” she explained. This means that the food they consume during five to six months at their feeding grounds needs to sustain them for the remainder of the year, as they engage in costly activities, like breeding and migrating.  

Migration

Speaking of migrating—after feeding for several months, gray whales migrate south for the winter—most traveling 5,000-6,000 miles to Baja California.

Toward the end of the feeding season, whales start to feed less and socialize more. Leigh has observed courting actives in the whales she studies. Males and females will surface synchronously together. Males will jockey for position next to a female. “Sometimes you see some penis’ flying in the air.” Ah, the life of a whale researcher.

“They all go to Baja,” Leigh remarked.  Mating often occurs in route, but gestation lasts about 12-14 months—the end of the following year’s migration.

Once in the warm waters of Baja, the whales engage in social behaviors, and the pregnant females, if they haven’t already, give birth to a single calf. Mothers nurse their calves in the tropical waters until they build up enough blubber reserves to survive colder waters to the north.

Then, in the spring, gray whales make a return trip north—again traveling 5,000-6,000 miles to feeding grounds, usually in the Arctic or sub-Arctic regions of Alaska. 

This costly migration occurs over and over throughout the long lives of these whales. Though we don’t know exactly how old gray whales get, it is probably something like 60-80 years, according to Leigh. That is a lot of migration.

Subgroup

As we migrated along the beach—contemplating the immensity of a 6,000-mile journey—Leigh clued me into the whales she studies in Oregon.

“These whales don’t make a full migration,” she explained. “They are what is called a subgroup.” More specifically, the Pacific Coast Feeding Group (PCFG). There are about 250 members of this group that arrive at Oregon’s rocky shores in about June and stick around until around October—feeding along the kelp beds that grow here.

It is these gray whales that Leigh watches bubble blast and suck benthos. It is also these whales that she knows by name and personality.

One of the objectives of her lab is to understand how this subgroup of whales is different from whales that make the full migration. For example, one of the graduate students in her lab looked at the caloric content of prey found in Oregon versus the arctic. Eventually finding them to be equivalent or higher. 

“We are still piece-by-piece trying to solve the mystery of the PCFGs,” said Leigh. Why do they stop?  What is their unique culture? Their challenges?  This is the crux of Leigh and her team’s research.

A couple of other subgroups exists. For example, a group of about twelve whales stops in Puget Sound in March to feed off ghost shrimp. Another larger endangered population of gray whales—the western gray whale population—migrates all the way to Russia. 

Sunlight reflects off the water on the beach.

Whale Research

We walked along the wet, compacted sand, moving south along the coastline at an easy pace. Pepper chased ahead following her joy and the surf.

“We study their behavior and body conditions,” Leigh explained, keeping a close eye on Pepper as she talked.

Studying whales is not an easy undertaking. Leigh’s lab uses different methods and technologies to help gather the data they need to better understand how the gray whales that reside on the Oregon Coast are doing.

“When we are with the whales, the first thing we do is get out the cameras and do photo ID,” explained Leigh. “Everything we do is linked to an individual whale.”

Next, the drones come out. Drones allow Leigh and her team to really see what they are doing. Body condition and behavior are two essential measurements taken from drone footage. 

A Gold Mine

Then there is the poop!

“We are looking for poop the entire time,” Leigh stated with a grin.

According to Leigh, capturing whale poop is not too difficult—you just need a lot of patience and a “really good boat driver.” Whales typically poop during their last fluke-out dive—called the terminal dive. After three or four blows in a row, the whale takes a final breath, dives, and out comes the poop (well, some of the time).

As soon as someone spots a reddish-brown plume in the water, they yell “poop!” And the team jumps into action. Using mesh nets, they scoop up as much poop as possible for testing.  You usually only have about 30 seconds before it sinks into the abyss. Whale poops can be as large as 4 by 4 meters. Yep, I asked (your whalecome). 

You might be asking yourself, why in the world would anyone want to collect whale poop?

“Poop from whales is a biological gold mine,” explained Leigh.  It can be used to determine a lot about the whale’s health and biology. Plus, it is a non-invasive method!

“We look at the hormones, what it is eating, and the microbiome of the animal,” Leigh went on. “We are looking at microplastic loads,” she also specified. Truly, a gold mine.   

Unique Personalities or Discoveries  

We continued along the flat glistening sand, sun on our backs. I asked Leigh how long she has been studying Oregon’s subgroup of whales.

“Six years now,” Leigh replied. She went on, “My hope is to continue for a long time. “

“These are long-lived animals,” Leigh explained. “To really understand their ecology, we need long-term studies.”

Leigh and her team hope to better understand what affects their reproduction and survival. 

So far, the lab has established “baseline knowledge.” Overall, it seems that how much gray whales respond to stressors varies greatly from whale-to-whale, year-to-year, and even day-to-day within an individual whale. Lactating whales, for example, will be generally very skinny. Stress hormones increase following a stressful event, like a propellor strike.

The goal now is to figure out what the drivers are—or, in other words, what is at the heart of the variation in responses observed in whales?

Hard-knock Life

Eventually, Leigh and I reached a small creek crossing—not wanting to get our feet wet, we turned around and headed north. It was nearly lunchtime, so getting back to our feeding grounds, I mean er, cars, made sense.

As we headed back, Leigh and I talked about the changes she is seeing in Oregon’s resident whales and what she sees as the potential drivers of these changes.

“The number of whales is lowering,” Leigh told me. Though she doesn’t know what exactly is happening to the whales, she knows they are not coming back. “There has been an unusual mortality event,” Leigh went on, “lots of emaciated whales on the coast lately.”

According to Leigh, kelp is also on the decline along the coast probably due to marine heatwaves and increases in urchins. This is a significant problem as gray whales feed a lot in these kelp beds.

She recalled the warm blob event of 2014 to 2016 and its impact on the marine system. “It changed the oceanography,” she explained, and both the kelp and whales were impacted. Prey availability reduction was measured, as well as a decline in the whales’ body conditions.  

Along the same vein, urchin populations have increased as their predators, like sea otters and sunflower sea stars, have become less abundant. Because urchins eat kelp, a larger urchin population is bad news for kelp.

Entangled in Strikes

Then there are the vessel strikes and the fisheries entanglements.

“One particular project I am interested in is noise pollution,” Leigh mentioned early on in our hike together.

Oceans are becoming noisy places. “90% of shipping is overseas,” according to Leigh. That means a lot of fast and loud ships that whales, and other marine life, must contend with. Leigh wants to understand how whales respond to all the noise.

To study the phenomenon, Leigh and her research team place hydrophones in two locations during the summer—one near the South Jetty where we were walking and another, near the much quieter, Otter Rock Marine Reserve. The goal is to monitor both sites for noise and to track the gray whales’ responses.

Listening is an important part of whale behavior. “The ocean is very dark,” Leigh explained, “you can’t see very far for navigation.” Whale communication relies on sound. Finding food, mating, and avoiding predators are all affected by a noise-filled ocean.

Leigh told me about a pilot project where her team tagged whales using suction cups. Each tag had a camera and accelerometer to track the activity of the whale over about a 24-hour period.

During one of these tagging events, they were able to observe one of the whales, Peak, move through the navigation channel.  What they found was compelling.

Peak dropped from about 2 meters below the surface to 5 meters during the traverse. He also took fewer breathes during his crossing.

It is easy to speculate regarding his behavior—Was Peak experiencing “fear?” Exercising caution? More research will need to be done.

How to Save Whales

So, what can we do?

As Leigh and I neared our exit from the beach, I asked her that very question.

“First, simple things that reduce the role of climate change,” was her initial response. “Drive less, fly less, eat less meat.”

For people that recreate in the ocean, her recommendation was more direct—“pick up your fishing gear” and “slow down.”

Leaving crab pots or other fishing gear in the water for extended periods of time can increase the likelihood that whales become entangled. 

Driving too fast and not watching for whales in areas that they occupy results in more strikes. “A lot of whales have propeller strikes.”

Finally, there are the less tangible things we can do. We can be informed about marine life and the changes occurring in our oceans.

“Educate, connect, and monitor our environment”—that is what Leigh and her team are working tirelessly to achieve.

If we can get on board and show similar interest in the ocean—perhaps through our own connections to marine life—then we are getting somewhere. After all, human activity and gray whales overlap. 

Whether you are fishing on a reef or purchasing something on Amazon, you are party to a human-whale interaction.

Whale Connections

Fortunately, Leigh and her research team have made connecting with Oregon’s whales easier than ever. They developed a website (individuwhale.com) where anyone can learn about the Pacific Coast Feeding Group on an intimate level.

“We profiled eight whales,” Leigh explained, “Talk about their lives and show them as individuals.”

By visiting the site, you can learn about each whales’ behaviors and habits—”are they homebodies or roamers?”—for example. Information about research methods and whale threats is also discussed on the site. 

The site shows you how to use markings to distinguish between individual whales. You can even play a fun game to test your knowledge. And the best part—you can then use what you learned to identify whales in the wild. 

Finding Whales

Let’s go wild—wild about whales! Where can we find these magnificent creatures?

Well, when it comes to the Oregon Coast, it depends on who and what you want to see.

Leigh told me that she has been doing helicopter surveys four times a month with the coast guard since 2019—with flights out of North Bend, Newport, and Warrenton. The main goal of the survey is to determine the distribution of whales over time and space in order to better manage entanglement risk.

With this data, however, Leigh was also able to tell me a bit about where and when recreators might want to look for whales.

The migrating gray whales come through in February and March and November and December, making these months a great time to look for whales off Oregon’s rocky shores.

However, Oregon’s part-time resident whales are around all summer—from June to October, with August being the peak month to see them. For the best views of these whales, head to Depoe Bay or Yaquina Head, according to Leigh.

But gray whales aren’t the only cetaceans that visit Oregon. Harbor porpoise is a year-round resident, though hard to see unless the water is exceptionally calm. Humpbacks and blue whales hang out for the summer, though farther offshore, with blue whales the closer of the pair. For humpbacks, July is a peak month, but for blue whales, it is closer to September or October. Then, Fin whales arrive in the winter.

Heading Home

Leigh and I continued to chat as we walked over the sandy dunes that separated us from the parking lot.

Though we didn’t see one whale during our hike together, spending time with Leigh was like getting a peek behind the curtain. Though the mystery of whales is not resolved, we are closer than we have ever been to understanding these sentinels of the sea. And with drones, poop, and Leigh and her team, we will only get closer. And that is something to get whaley excited about.

Hike with a Mushroom Citizen Scientist

Tiny unidentified mushrooms growing on a stump near the start of the hike.

Tucked in the duff on the forest floor or growing on the stump of a dead tree—mushrooms captivate the imaginations of many, while others rarely give heed. The beauty and variety of mushrooms, as well as their reputations as delicious edibles, sparks interest for many.

Mushrooms are the fruiting bodies of fungi—a diverse group of organisms, best known for their ability to decompose organic matter. An entire kingdom of life, fungi are mostly unknown (all except a few favorites).

Personally, I have long been fascinated with mushrooms. Their colors, textures, and earthy scents have long drawn my attention. The result— a phone camera full of photos of mushrooms and a lot of fungi-focused questions.

Driven by my fungal ineptitude. I reached out to the Willamette Valley Mushroom Society to see if someone there might be willing to help enlighten me. And to my great fortune, Autumn Anglin, Treasurer for WVMS, answered my call.

Autumn has also fallen under the spell of mushrooms, and by her own admission, fallen hard. Ever since her first encounter with the mushroom hunting world in 2016, Autumn has thrown herself into discovering and understanding them.  Today she leads a mushroom study group and is an active citizen scientist, gathering mushrooms for careful study and genetic analysis.

Autumn suggested we meet at Lewisburg Saddle Trailhead, not far from where I live, where she promised to share with me the scientific side of mushrooms. I emphatically agreed. 

The Hike

  • Trailhead: Lewisburg Saddle Trailhead
  • Distance: approximately 1.5 miles
  • Elevation gain: approximately 250 feet
  • Details: Ample parking at trailhead with overflow parking a bit futher down the road. Pit toilet available. No parking pass required. Roads to trailhead are paved.

A Cold Day in November

It was a chilly day in November.  A freeze set in the night before and a dense white fog shrouded the air like a mystery. The Douglas-fir forest lay still in the mist when I arrived at the trailhead.

Autumn was there ready. Armed with a wicker basket and, as I would soon find out, an unmatched enthusiasm for all things mushroom.

We quickly made a start down the gravel trail in the direction of the new growth trail cutoff.  As we walked along, Autumn told me about her start with WVMS, and how her involvement has grown over the last couple of years. From joining mushroom forays to leading study groups, to her most recent work —a nearly complete at-home genetics lab. 

Stump Stop

It didn’t take long, however, before something caught Autumn’s eye. She motioned me over to a stump on the side of the trail.

“There is a lot of mushrooms on this little log right here,” she noted as we both knelt to get a closer look. She pointed out “a little jelly type” mushroom next to another completely different species, just a few inches away. Larger mushrooms grew from the side of the log.

Autumn pointing to one of the many mushrooms we found growing on a tree stump.

The hunt was on. We started looking for mushrooms everywhere. We looked along the side of the gravel road that sloped upward for black cups, a favorite of Autumn’s. Despite our efforts, we didn’t see any black cups. We did, however, see a few gilled mushrooms, including one with a tan, umbrella-shaped cap that smells like sperm.

Clavulina Rugosa

Next, we saw a small white coral fungus—Clavulina rugosa or wrinkled coral fungus—growing straight up from the forest floor. C. rugosa is short, only about 3 inches tall, with branches that end in blunt tips. It isn’t the most glamorous mushroom, but what it lacks in showiness, it makes up for in reliability.

Growing near Douglas-fir, often in rings, C. rugosa is a common mycorrhizal fungus in Oregon. As mycorrhizal fungi do, C. rugosa provides nutrients and water from the soil to Douglas-fir trees in exchange for the sugars the trees exude from their roots—a symbiotic relationship essential to a healthy forest.

“Our study group calls it our friend,” Autumn remarked. “We have seen it every time we go out in the winter.”

Clavulina rugosa growing amongst the Douglas-fir needles and moss on the forest floor.

How to Know a Mushroom

At this point, we dropped down onto the new growth trail and headed deeper into the forest where we would see even more Clavulina rugosa among the trees.

The distinct characteristic of the C. rugosa made it easy to tell apart from others, but this is not the case for many mushrooms you encounter in the Pacific Northwest. As Autumn put it when asked how many different species there are in Oregon, “We have a lot!”

Thus, identifying mushrooms is a real challenge.

“My background is I am an artist,” said Autumn. “My observation skills being an artist has helped by a lot.”

To know a mushroom, you must look at the details the way an artist does. Look from all angles. Use your senses! Look, feel, and smell mushrooms. Just don’t taste.

“Run your finger over the stem and gill.,” Autumn suggested. “We can’t tell anything just by seeing a cap.”

Mushroom Anatomy

Another thing helpful when working on mushroom identification is to know something about mushrooms anatomy. Autumn taught me a few terms on our hike together.

“Stems are stipes.” The top layer, or “skin,” is called the pileus layer. “Flesh is everything on the inside, but not the gills.” Gills sit below the cap of some fungi and aid in spore dispersal.

Then there are all the terms used to describe gilled mushrooms—the group most difficult to identify. Words like notched, decurrent, forked, tiered—tumbled out of Autumn’s mouth, as we turned over mushroom after mushroom to look at the gills.

Indistinguishable

However, even with careful study of a mushroom in the field, it can still be impossible to tell with certainty some mushrooms apart just by looking at them.

Autumn explained that even the first level of division in Kingdom Fungi, which splits fungi into two main phyla—Basidiomycete and Ascomycete—requires microscopy to distinguish. Basidiomycetes are identified under the microscope by their balloon-shaped reproductive cells called basidia, with spores that develop outside of the cell on small projections.  While Ascomycete cells look more like “sausages with circles inside them,” Autumn described; the circles being the spores that develop internally in reproductive cells called asci.

Luckily, a lot of microscopy work has already been done, so breaking up fungi into phyla is more a matter of looking it up in a reference book.

But it still takes a lot of work to identify a mushroom, and microscopy is still needed in some cases to tell similar mushrooms apart.

Spore prints—spore deposits on paper—is another helpful tool for identification.

Autumn recommends getting a variety of mushroom reference books to aid in identification. Just make sure they work for the region you are interested in studying. A couple of her favorites are “Mushrooms of the Redwood Coast” by Noah Seigel and Christian Schwarz, and “Mushrooms Demystified,” by David Arora.

Blackfoot Polypore and Xylaria Hypoxylon, Oh My!

It was at about this time that Autumn really became animated, as we started spotting one cool mushroom after another. Eyes bright, a cheerful inflection to her voice, Autumn talked about her mushrooms with the tenderness reserved for old friends and loved ones.

“Blackfoot polypore,” Autumn sang out, reaching down to pick up a branch with a caramel-colored mushroom attached. “They only grow on sticks and dead things,” she went on, turning over the mushroom cap to reveal a porous undersurface and its “black foot,” a dark region where the stipe (or stem) touches the Earth.

Then, moments later she spotted another.

“This is one of my favorites!” Autumn exclaimed, pointing out a cluster of thin antler-shaped mushrooms, black in color with white tips growing on some rotting wood. “Xylaria hypoxylon.” 

“They are really cool,” Autumn explained. “Feel it!” she suggested, “They are rubbery and tough.” I pulled at the dark strips with my chilled fingers—the wiry body of the mushroom held together firmly.

The white tips are covered with spores, Autumn explained. In the winter, X. hypoxylon, also called “candle-snuff fungus,” produces asexual spores that coat the mushroom.

Decomposers

“The amazing thing about Xylariaceae,” Autumn continued, is that “they decompose more than any other group of mushrooms.”  Xylaria hypoxylon is one of the thousands of mushrooms in this group.  It is our local decomposing superhero. 

Fungi in general are known for their role as decomposers. When I asked Autumn why she thought fungi were important, decomposition was her simple answer. “Fungi and lichen end up making our soil. They are the foundation of our soil,” Autumn elaborated. From death springs life.

Wood Wide Web

Upon reflection, Autumn added in response to my question regarding fungi importance—”They help communicate.”

Scientific understanding of the “wood wide web” has taken off in recent years, as more research has shown just how important fungi are to a forest. Mycelia extend and spread below the ground creating connections between individual tree root systems. Water and nutrients are provided across this network to trees by the fungi, while trees supply sugar and carbon to the fungi and, at least in some cases, to other trees in the network.

“It’s a symbiotic relationship,” Autumn stated. “It is amazing.”Forests are not just a collection of trees. Rather, they are entire ecosystems—plants, animals, insects, microbes, fungi, etc.—connected by interdependence, as well as competition. 

“We should be thinking of forests as whole living beings,” Autumn remarked. We need to see the forest through the trees.

“And we are part of that ecosystem too.”

Be afraid, Be very afraid

As Autumn turned over one of many brown gilled mushrooms we spotted on the forest floor, she spoke:

“People are afraid of fungi,” she said, “but picking mushrooms is okay.” 

She went on to explain that most of the fungi, the important bits, are underground. When you pick a mushroom, it is analogous to picking an apple off an apple tree. Heck, if done right, you might even help spread its progeny.

“Use a basket or bag with holes to spread spores,” Autumn suggested.

Of course, there are some limitations. “Don’t rake up the forest,” Autumn instructed. But if you find something edible or want to study it, picking a mushroom is acceptable. 

Gear

Autumn carried her own beautiful wicker basket on her arm, while we hiked. 

She stopped to show me the contents: pen, notebook, UV flashlight, whistle, paper lunch bags, wax bags, and a tackle box.

Autumn explained that in order to do a scientific study of a mushroom, she tries to get multiple samples at different ages.  The tackle box allows her to separate out smaller samples, while the wax bags and paper bags are for larger specimens. “Never use plastic bags,” she cautioned. “They will turn to goop.”

Poison

Still off-trail, we noticed a tall, white shaggy stemmed mushroom.  The edges of the cap were also jagged, remnants of a veil — a thin membrane that covers some mushrooms before they are fully grown.

Lepiota,” said Autumn. “Poisonous.”

All members of the Lepiota genus are poisonous. Many mushrooms are poisonous, even deadly, another reason people often steer clear.

But, according to Autumn, “all mushrooms are fine to touch.” You just need to wash your hands before eating or touching your mouth, she advised.

“Chemical compounds in fungi need to be metabolized to be dangerous, Autumn explained.

This shaggy species of Lepiota is poisonous.

Russulas

Autumn and I headed to the other side of the tree-lined path. We kicked at a few of what looked like “mush humps”—areas where mushrooms have raised the soil as they begin to come up—but didn’t see anything growing underneath

However, one type (or genus) of mushroom we saw a lot during our ramble, and are often found hidden in a mush hump, are Russulas.

“They are one of the most common, prolific mushrooms,” said Autumn. They are also “under-identified and misidentified,” despite their commonality. Not a lot of DNA analysis has been done on the group. 

The ones we saw had shiny, soft pink caps, but this is not true of all RussulasRussulas come in a variety of bright colors. Autumn picked one to point out the identifying features.  “The main thing is there,” Autumn pointed to the bottom of the mushroom, “gills are attached right to the stem.” This is the signature of a Russula.

Other features include white or yellow stipes (stems) or gills, and a “skin” on the cap that peels back.  Another interesting feature of russulas is their unique flesh—spongy rather than stringy. Their stems “snap like a piece of chalk.” And apparently, if you throw a russula against a tree or similar surface, they “explode.”

Unknown

Autumn and I continued our off-trail adventure in the area of the forest where she discovered a new mushroom just last year.

The fungus itself was first cataloged genetically from a soil sample in the 1970s and 80s but was never described further. Autumn had seen and documented the fungi’s fruiting body for the first time!

As exciting as the discovery was, however, there was still more work to be done. The fungi would need to be found again, Autumn explained, “five or six more times” before it can be named. 

Our eyes scanned the duff, sweeping the area slowly as our feet sunk into the spongy earth.

More to Discover

Surprisingly, very few of the mushrooms on the planet have been identified, so discoveries like Autumn’s are not all that unusual. Experts estimate that as much as 90% of mushrooms out there are waiting to be discovered and given names.

“Most of our mushrooms are European,” Autumn said, “the U.S. doesn’t have that many named species.”

This is problematic because it is likely that the North American version of what we think is a “European mushroom” is probably genetically different from its European counterpart. Work needs to be done to find these differences and, thus, discoveries to be made.

Look Closely

And discover we did! Not anything new to science, but plenty more striking and fascinating mushrooms. 

We saw “stunning” Marasmius plicatulus with their velvety, chestnut orange caps and thin, dark mahogany colored stipes. “They are really sturdy mushrooms,” Autumn noted as she picked one for closer examination, revealing its widely spaced gills. 

The “stunning” Marasmius plicatulus.

Then there was the small, understated Inocybe geophylla mushroom —with its mostly lilac-colored cap — a yellow spot at the center. Inocybe mushrooms have gills that are detached from the stipe.

We saw (and I later tasted) a jelly fungus with the common name “cat’s tongue,” a member of the Pseudohydnum genus. The mushroom was translucent with the texture of a gummy. It also had small teeth on the bottom of the cap, giving it a tongue-like look. Autumn offered me a bag to collect some in. I washed them off the best I could before taking them home to prepare and eat.

Finally, growing on a Douglas-fir cone, a new favorite—the small, but stately earpick fungus, Auriscalpium vulgare. Itty-bitty and brown, with teeth that look like fuzz on the bottom, the earpick fungus immediately stole my heart. How have I never seen these! Autumn told me that they grow exclusively on Douglas-fir cones.  I will never look at a cone the same way again.

Mycologist Pace

At this point, Autumn and I had probably hiked about a quarter-mile on the forested trail.

I learned quickly — you can’t really “hike” with a mycologist. It is more like a focused crawl.  You bend over a lot.

We laughed at our slow progress, as we headed back onto the main trail to pick up the pace (only slightly).

For Every Season

Autumn and I followed the trail through the young forest, the mist contrasted against the unpruned trunks of the skinny trees and large stumps. A chill hung in the air.

As we walked, we talked, keeping a watchful eye out for more mushroom gems. Autumn had hoped to find one of her favorite groups of mushrooms, black cups. But today they eluded her.

“It must be too early for black cups,” she remarked.

Too early. Too late. Mushrooms are picky. Some more than others. They pop up when conditions are right, and just as quickly, they disappear.  Then again, they may not come up at all.

Morels are particularly challenging weather watchers.

“Morels need three weeks at 50 degrees before they fruit,” explained Autumn. “If it gets too warm too fast or stays colder longer…” she trailed off, but her face said it all. “Morels are temperamental. They can sit underground for 50 years.”

For Every Habitat

We walked past a tree with some cool shelf mushrooms growing on it. I snapped a picture and Autumn grabbed a sample, placing it in one of the compartments of her tackle box.

An unidentified shelf mushroom.

On a dead tree next door, we saw an orange jelly mushroom growing. “Probably not Naematelia aurantia,” said Autumn—a.k.a witches butter.

Witches butter grows on decaying hardwood. This orange jelly was affixed to a conifer. “Dacrymyces chrysospermus—a basidiomycete with two, as opposed to the typical four, spores at the tips of its reproductive cells—doesn’t grow on hardwoods. It grows exclusively on conifers.

Just like other forms of life, fungi have habitat requirements. Knowing where a mushroom will grow can help you tell mushrooms that might otherwise be indistinguishable (or at least without a microscope) from each other.

Planting Biodiversity

We continued down the path. Stopping occasionally to check out a mushroom or two along the way.

Even though we were hiking through a plantation—a forest replanted for timber and not necessarily known for its biodiversity—Autumn noted just how many different types of mushrooms we were seeing.

“Inside plantations, I find that the diversity seems to be a lot more,” she commented.

Biodiversity is important. Biodiversity produces functional ecosystems that are resilient and produce many natural products and provide services humans, among other organisms, rely on.

One of the goals of Autumn and her WVMS Fungi group is to document mushroom biodiversity at each of the study sites.  Using an app called iNaturalist, her group has recorded over 700 observations of mushrooms of a variety of types over a one-year period.

“I feel a sense of urgency due to the climate crisis to get out here,” Autumn went on. She wants to make sure we know what is there!

“It is really important that we preserve this,” she stated empathically.

Chemical Signals

At the end of the new growth section of the trail is a small log bridge that you step through before entering old growth. Here Autumn and I noticed a lot of different mushrooms growing on and around the structure.

“Careful of tan, yellow mushrooms,” warned Autumn pointing to a cluster growing on a decaying stump. “They can be really poisonous.”

Each species of fungi produces its own chemical suite designed to attract, deter, and sometimes kill other organisms. As sessile beings, chemistry is how fungi communicate.  

While the chemistry of mushrooms can be deadly, it can also be a benefit to society. Humans have harnessed compounds extracted from fungi and other sessile organisms as medicines and supplements. Most of the commonly prescribed drugs in the United States, and at least 1/3 of medicines globally, are based on naturally sourced chemicals.

“I never eat white gilled mushrooms,” Autumn confessed. The chemistry is just too risky.

Waxy Caps

Stepping over the bridge, Autumn and I were met with clusters of orange-capped mushrooms.

“Waxy caps,” Autumn exclaimed, “one of the most stunning mushroom genera.”

Waxy caps, or Hygrocybe, are visually stunning. Autumn pointed out how the vibrant cap color contrasted with white, widely spaced gills.

Hygrocybe is also mycorrhizal with Douglas-fir—networking with the roots of trees. However, from where we still the nearest Douglas-fir tree was maybe 100 yards away.

“Does the network go all the way out here?” Autumn wondered out loud.

We were baffled. And impressed. Why not?

Old Growth Delights

Walking through the old growth forest, was like entering a different world compared to the plantation we had hiked through earlier. The trees were larger and more varied in age and species—including Douglas-fir, Western Hemlock, Big Leaf Maple, and Pacific Yew. Leaf litter covered much of the soil, and shrubs, ferns, and small trees added vertical structure to the scenery.

And then there were the mushrooms!

And a cluster of brightly colored Hypholoma with black spores and gills that turn green under UV light, as demonstrated by Autumn.

The List

We continued hiking the muddied path, stopping to look at mushrooms as we discovered them. I couldn’t believe how much we were seeing. A mushroom newbie, I asked Autumn if she had a recommendation for mushrooms to learn first.

“I would say try not to get overwhelmed,” Autumn replied. “You will see a lot of things you won’t be able to identify…try and identify to family and genus to start.”

So, what are the top groups of mushrooms Autumn recommends learning first? Here they are in the order mentioned.

First on the list, Red-banded polypore, or conks. Widespread wood-eating decomposers, red-banded conks are identified by the orange to red stripe that runs between the darker inner and lighter outer edge.

Red-banded polypore found along the trail.

Next, is Mycena—small in stature but large in group size. Mycena is a genus of tiny mushrooms with translucent, fibrous stipes and white gills “you see everywhere,” according to Autumn,

Agaricus is a common urban mushroom. These white to brownish mushrooms with “super tiny, closely spaced gills.”

Stereum is another—a genus of mushrooms that grows on decaying wood. Autumn and I found some growing on hardwood log next to the trail. These thin shelf mushroom clusters are decorated in wavy bands of greens, yellows, and browns. 

Russulas made the list; along with Xylaria hypoxylon and bird nests.

Perfection

As Autumn contemplated what else to include on “the list,” we walked and observed. We saw a cluster of mushrooms (too non-descript to identify), followed by a large single mushroom coated in white (it had been parasitized). 

A parasitized mushroom.

Suddenly, Autumn and I were stopped dead in our tracks. In front of us was a large amanita.

“A perfect specimen,” Autumn spoke, her eyes sparkling. 

I took a few pictures before Autumn pulled the Amanita vaginata, or Grisette, from the earth, revealing its true height.

Amanitas are mycorrhizal species—again, part of the wood wide web.  The mushrooms vary in size from small to large. They have white spores, and their stipes and caps are usually decorated with veil remnants.

As mentioned earlier, veils enclose some mushrooms when they first emerge, later expanding and breaking apart. In Amanita, this means patches or warts on the older caps, and skirts or scales on the stipe.

Amanita can be dully or brightly colored, like the well-known Amanita muscaria, and their caps flatten with age. The Amanita cap has a distinct margin and bell shape with a “nipple” or umbo at its center.

“That is gorgeous!” Autumn exclaimed, overcome with the beauty of it.

We added amanitas to the list. After all, Amanita muscaria is “the poster child of mushrooms,” said Autumn.

The perfect specimen of Amanita vaginata!

Puffballs

After our Amanita discovery, the trail veered back onto a gravel forest road that would take us back to the trailhead.

Autumn’s head swerved around looking for earth star mushrooms along the road—a type of puffball mushroom with a round “puffball” center in the middle of star-shaped rays.

We didn’t find any earth stars, but we did find a few puffballs further down the road hiding in the grass. Though difficult to tell apart. Puffballs are wildly entertaining. Poking a puffball will send out clouds of small brown spores.

Puffballs were also added to the list.

Puffballs found hidden in the grass.

Ascomycetes

We still had some more searching to do as we neared the trailhead.

Autumn was determined to find Helvella vespertina.

“Ascomycetes are my favorite,” Autumn told me, and Helvella vespertina is one of the largest mushrooms in the phylum. (Most ascomycetes are very small and usually lichenized, partnering with algae or cyanobacteria.)

It didn’t take long before we ran across the structural beauty of Helvella vespertina. The first ones we found were parasitized with a white fungus, hiding its black cap, but not its unique shape. Later we found an untouched sample.

It is hard to describe Helvella verspertina—the stipe and cap are wrinkled and folded making it look almost “brainy.” Autumn called them “bizarre and consistent,” an equally apt description.

Morels are the other large ascomycete mushroom with a similar vibe. We added both to our ever-growing mushroom list.

The sculptural Helvella vespertin mushroom.

Mycology on the Mind

Still with several hundred feet to make it back to our car, Autumn and I continued to hunt mushrooms.

We found several more interesting specimens including a Lactarius, or milkcap mushroom that when you break the cap oozes out a white milk-like substance.  

While we hunted, we also chatted more about Autumn’s citizen science work. Thanks to her passion for mushroom biodiversity documentation, her research group earned a grant to send in 50 species this year for DNA analysis to FunDiS, or Fungal Diversity Survey, a nonprofit focused on fungi conservation. 

Now, she plans to continue her work by doing her own DNA analysis of fungi she finds, and by collaborating with researchers and interested groups. With a shoulder shrug, she even hinted at the prospect of going back to school to study fungi.

Mycology Matters

After spending the morning hiking with Autumn, it was clear to me just how much mushrooms and fungi are a part of her life. Her interest and enthusiasm were infectious, and I couldn’t help but smile every time we ran across another mushroom that caught her attention.

I have always enjoyed mushrooms, but Autumn reminded me of just how much fungi matter. It is easy to forget the work fungi are doing in the soil, to take them for granted, but when mushrooms appear they serve as a reminder of the important role fungi have on the planet. 

Seeing mushrooms is like seeing into an otherwise hidden world. So, take the time to get to know a mushroom or two.  Perhaps, learn their names. And give thanks that there are those out there, like Autumn, ensuring their conservation.

Hike with a Beaver Ecologist

Alsea Falls from the lower viewpoint.

Beaver! A surprisingly loaded word. The largest rodent in North America. Oregon’s state animal. The American Beaver is touted for its remarkable ability to engineer waterways. While simultaneously villainized as a nuisance species. Trapped for its fur well into the 19th century, this activity still occurs today, though not to the levels seen during the fur trade.

There are a lot of strong opinions about beaver. They are both beloved and hated. Removed and reintroduced. Marveled at and frowned upon. Yet, for all the attention they get, there is a lot we still don’t know about them.

This is why, after a long day of teaching high schoolers, I met up with Vanessa Petro, who has been studying the American Beaver for over 10 years, to walk and talk about these surprisingly enigmatic, charismatic creatures.

The Hike

  • Trailhead: Alsea Falls Trailhead
  • Distance: 2.4 miles (w/shorter and longer options available)
  • Elevation Gain: 300 ft
  • Details: Ample parking and pit toilet available at trailhead. Drive to trailhead is on well-maintained gravel roads. $2 for parking or use National Forest or other Recreation pass.

The Drive

Vanessa and I drove out to the trailhead together. As we rode along, we chatted about various aspects of our lives—from childhood to career to motherhood.

Vanessa spent her childhood in Pennsylvania, surrounded by nature and the outdoors. “I grew up going out the backdoor and disappearing into the woods,” said Vanessa, much to the chagrin of her parents.

But it wasn’t until she encountered a magazine article featuring Dr. Gary Alt, a renowned black bear biologist, that she initially got hooked on wildlife.  Vanessa saw what Dr. Gary Alt was doing, and as she put it, she “wanted to do something like that.”

Vanessa’s passion for wildlife and the outdoors continued into high school. She was active in hunting during her teen years. And she enjoyed classes in the biological sciences. In particular, Vanessa mentioned an ecology teacher that inspired her and also invited her to compete in a state-wide natural resources competition called Envirothon.

College and Career

Vanessa’s was on a path. After high school, she attended Sterling College, “the smallest accredited college in the United States.” The college only offers environmental study-based majors. Vanessa studied conservation ecology.

“I lucked out while I was there,” Vanessa explained, “There is a large emphasis on hands-on experience. “By the time she graduated from Sterling, Vanessa had already completed several seasons of summer and winter field work, including an internship with Sequoia National Forest working on a forest carnivore monitoring project.

After graduation she bounced around the U.S., living in 11 different states, as she continued to find seasonal wildlife work where she could. “I have no regrets,” Vanessa smiled, “except for maybe a few men.”

Eventually, Vanessa settled at Oregon State University to conduct graduate research.  And once graduated, continued her research work at OSU, which is where she is today. 

Now, married with one child and another on the way, Vanessa spoke adamantly about the challenge of balancing a career with family. “In natural resources, you can’t really get married and have children at the start of your career,” she said pointedly. “I had to wait.” Even today, with a supportive boss and colleagues, Vanessa spoke of the difficulty. “There is a high attrition rate for women in STEM fields,” she noted.

Why beaver?

Before long we pulled into the parking lot for Alsea Falls and our trailhead. And after a quick restroom break, Vanessa and I headed down the muddy path to Alsea Falls.

Vanessa has been studying Beaver in the Alsea River Watershed for over 10 years. So, as we began our descent, I needed to ask— “Why beaver?”

“For me, I am definitely split between terrestrial and aquatic systems,” Vanessa responded. “And they are in between.” Beaver are semiaquatic—spending part of their time and on land and part of their time in water—taking advantage of resources in both environments.

In addition, many people care about beaver. “There is a lot of conservation interest in beaver in our area,” Vanessa went on. “And there is a lot we don’t know about them.”

Unknowable

Despite their dominating presence in the Pacific Northwest’s history, we don’t even know the most basic information about beaver in this region. “No one can tell you long they live or how many there are in our state,” explained Vanessa.  Their ecology is a mystery.

So, what is happening? Most studies center around using beaver in restoration and/or the relocation of beaver. Questions are very specific and very limiting. For example, “we don’t know the average home range sizes of beaver throughout our state,” but we have movement data for relocated beavers. Yet, beavers that are relocated do not behave the same as naturalized beavers, so it would be like comparing apples to oranges. Thus, there is a gap in knowledge.

Alsea Falls

Vanessa and I continued until we reached the first Alsea falls viewpoint. We stepped out onto the bedrock ledge to get a view of Alsea Falls and snap a few pictures. The ground was slick, but that didn’t stop Vanessa from clambering up closer to the falls for a photo when I asked.

We continued down to the lower viewpoint for another view of the falls from a wider angle. I noticed how the autumn leaves opposite the river were striking against the dark greens and greys of the forest. We looked out at the rushing water.

Dammed if you do, dammed if you don’t

“Do you know what is cool about where we are standing?” Vanessa started, looking upstream, just above the waterfall. “This waterfall is a known barrier for salmonid fish.” But that isn’t the interesting part. Vanessa went on to explain that not too far upstream there is a two-mile stretch of river that beaver have colonized, building dams and creating the perfect habitat for fish.

Beaver are considered ecosystem engineers—they create habitat other species, like salmon, rely on. Birds, amphibians, and invertebrates all take advantage of the engineered wetlands, pools, and other habitats built by beaver. The list of beneficiaries is long.

The site upstream of Alsea Falls is so ideal for salmon that at one point multiple stakeholders wanted to build a fish ladder to provide the fish access to it. The idea eventually lost steam, but just the fact it was considered, says a bit about the quality of fish habitat beaver have the potential to provide.

However, it is important to note that not all beavers make dams. They often don’t need to.  And without dam building the ecological benefit of beaver is non-existent. 

If water around their dens and foraging areas is deep enough to protect them from predators, a beaver won’t build a dam.  Beaver innately rely on these cues to know when to build. Below Alsea Falls dam making isn’t as frequent and “habitat is patchy,” said Vanessa.  The cues aren’t there.

The two-mile stretch of beaver dam habitat above Alsea Falls that everyone desires, well, “that doesn’t occur frequently on the landscape,” said Vanessa.

“Salmonid habitat ends right here,” stated Vanessa, matter-of-factly. But beaver habitat, well that is another story. We followed the trail back upstream with beaver in mind.   

Looking down from Alsea Falls toward a log jam.

Beaver Forage

Back at the top of the trail, we took a sharp left onto a bridge that crosses the Alsea River. I looked down at the flowing reflective waters. Vanessa looked out toward the greenery lining its edges with an eye out for beaver sign.

Beaver are herbivores—they eat plants. More specifically, they snip off smaller diameter branches of trees and shrubs, eat the leafy greens and outer layer of bark where the cambium is.

They are picky eaters though. “They will cut salmonberry, red alder branches, willow, and vine maples… but they won’t touch Pacific ninebark,” said Vanessa. “They will eat lady fern,” but avoid stink currant.

Beaver generally stay close to the water and often sit along its edge while consuming the forage they collected.  “They will forage on average about 30 meters (~100 feet) from the waterline,” stated Vanessa, “but will go further out if they have to.”

“They look for the best of the best,” Vanessa told me later during our hike. Though the Alsea Falls watershed provides several examples of suitable beaver habitat, you won’t find them everywhere. “There are still patches of unpalatable vegetation and undesirable habitat that occur throughout the area.” When it comes to establishing a new home, they look for something equivalent to what they had in the past or better.

“There are no beaver here,” said Vanessa, having fully assessed the area and we continued up the trail.

Looking out over the Alsea River bridge.

Forest Diversions

We headed deeper into the woods, following the muddied trail along a ridge above the creek. The trail weaved through the Douglas-fir trees whose branches caught the late-day sunlight in a bright burst of gold.

Seeing the stately Douglas-fir trees reminded Vanessa of her husband, Andrew Merschel, a forest ecologist. “He just defended his Ph.D.,” she said proudly.

Through his research, Andrew reconstructed the fire history of Douglas-fir forests west of the Cascades, similar to the one we were hiking in.  “The assumed fire return intervals are wrong,” said Vanessa. The actual fire history in this region, she explained, demonstrates a more complex reality than what has been traditionally taught. 

It was fun talking to Vanessa about her husband’s forest research. It was a wonderful diversion. But we were there to talk beaver!  “I want to know more about your research,” I said, as we moved slowly up the path.

Trees filtered the light as we walked through the forest.

Unsuitable

We hiked past another unsuitable spot for beaver—a site heavily forested with desirable alder trees but that was also laced with undesirable stinking currant. No sign of beaver.

Then the trail widened, curving away from the South Fork Alsea River, and began following the bank of Peak Creek.  Here our luck changed.

Much of Vanessa’s research centered around identifying beaver activity, so as we neared an access point on Peak Creek, Vanessa led me down to the water’s edge to look for beaver sign.

Grove of alder. No sign of beaver here.

Beaver Sign

Vanessa explained that many people assume that if they don’t see dams, there are no beaver present. But, as Vanessa made clear early on, not all beavers make dams.  A lot of them don’t need to.  So, to assess beaver activity we need to look for other signs of their presence.

Vanessa climbed down to the water balancing on logs to reach out into the creek where some branches of western redcedar hung over the water. She pulled at the branches, inspecting the tips of each branch until she found what she was looking for.

She directed me to come take a look. The end of the branch she held in her hand was clipped with clear beaver incisor marks. Looking at the branch I imagined a beaver grasping at the branch and snipping it off with its big front teeth, then eating the outer layer of the branch, as Vanessa put it, like eating corn on the cob.

Vanessa noted that clipped branches can be found up and down creeks where beaver reside, but they can be tricky to spot if you don’t know what you are looking for.  People often make the mistake of just looking near the waterline, Vanessa explained, but water levels change all the time, so what is unreachable one day for a beaver might be perfect during high flows.

Feeding stations, a collection of cut limbs along a shoreline or in a protected area, and food rafts, a bunch of clippings floating in the water, are other signs of beaver foraging.

Smelly Stuff

Foraging sign is just one clue or indicator of beaver activity. I asked Vanessa if there is anything else to look out for. “Scat and scent mounds,” she replied.

Scent mounds are territorial markers beavers create out of mud and detritus. They essentially pile up these materials along the shoreline or island in the water and deposit castor, or castoreum, a strong-smelling substance released from specialized glands.

“What does it smell like?” I asked.

“BBQ sauce and vanilla,” Vanessa said. She explained that she often brings castor with her to outreach events and asks people what they think it smells like. BBQ sauce and vanilla are the most common responses. “Castor glands are used to provide ‘natural’ vanilla flavor to ice cream,” Vanessa remarked. Later, a quick google search reveals that beaver butt secretions are used for flavoring in many different food products.

Beaver scat, on the other hand, is less smelly. “Imagine little cylindrical balls of sawdust…sitting in a pool of water,” said Vanessa. It is rare to find beaver scat because of their semi-aquatic nature. “You only see it where they are active,” Vanessa remarked.

We didn’t see any scat or scent mounds during our hike.

Beaver Dens

However, a commonplace to find scat, if you find it at all, is near a beaver den.  A beaver den is essentially the home of the beaver. Beavers use their dens to rest, hide from predators, and raise their young

Beaver den structures in the Pacific Northwest are not usually lodges—dome-shaped structures built with sticks and mud—like are seen on nature shows. Rather, beavers in Oregon, and neighboring states, often dig into the banks of a stream or river—creating a “bank den”—often choosing sites under trees with roots that provide an extra element of structure and protection.  This is a more practical configuration in constrained waterways in Oregon than a lodge. Fluctuating water levels also means that “most colonies will have multiple dens.”

Vanessa and I looked to see if we could find a den under the cedar tree that had been munched on, but there wasn’t any clear opening.

I asked Vanessa about the size of the den, as we prodded around the riverbank. “They are about a foot wide” at the entrance, said Vanessa; and “chambers are actually small.” To find the dens, she usually uses a meter stick to wiggle underneath a bank.  “The tunnel will go into the bank and then will cut up at an angle,” explained Vanessa.

Aging Sign

Having sufficiently checked the area for beaver sign, Vanessa and I decided to continue on the trail.  We were hoping to reach Green Peak Falls, the turnaround point for our hike before dark and we were losing light fast.

As we clambered our way up, Vanessa told me more about her research. “Right now, I am conducting a 5-year beaver dam ecology study in this basin,” she said. “We visit the same sites every year to census of all the dams and beaver activity.”

“We will note all the different types of activity,” Vanessa went on… and “give an age status based on the newest sign identified.” She noted how the clipped cedar branch we had inspected earlier had a lot of “black spotting.” This suggests that the clipping was at least a year old. On the other hand, “it if is clear white,” explained Vanessa, which indicates “they are actively there.”

Chatter

As we walked, I noticed a medium-sized log on the trail that had been “chewed into.”  Beaver? I thought. No. Upon closer inspection, the markings had no incisor imprints. The tree wound was human-inflected, Vanessa assured me.

Having seen similar markings before, I asked Vanessa what was going on.  The markings are called “chatter,” she told me. Beaver will sometimes girdle a tree to wear down their incisors that continue to grow throughout their lives, or possibly to bring down a tree to access more food. In this case, the beaver is doing a lot of “chewing and spitting” and “a huge pile of woodchips” will build up at the base of the tree being cut down.

Vanessa and I “chattered” on.

Should I Stay or Should I go

Before long we reached the stairs that lead to the base of Green Peak Falls. We could hear the rushing waters and paused to finish our conversation before heading down.

“There is another thing with beaver,” Vanessa stated, “just because they occupy a site doesn’t mean they will remain there.”

The duration beaver typically occupy a stream reach and why remains uncertain. “They are all over the map on how long they stay at a site,” Vanessa explained.

The movement of beaver within a watershed is something Vanessa is hoping to find out with her future research. “We have some short-term studies,” she explained, but not enough to really understand what is happening in the bigger picture.

Part of the issue is that beaver dams in Oregon tend to be ephemeral. “By springtime, only 20-45% remain intact from the previous fall,” Vanessa remarked about her study in the Coast Range. And “they only rebuild 7-30% of the time.” More often beaver choose to build a new dam in a new location.

For her study area, “The total number of dams has been consistent at the landscape level over time,” said Vanessa. But much of beaver colonization patterns remains a mystery in response to dam failures.  Will they stay? If they stay, will they rebuild? Or will they go and come back later in the year? There is much still to figure out. 

Vanessa told me about a year when she surveyed her sites, and all the dams failed at one of them, but the beavers remained and didn’t rebuild. But a tributary or two over, another group of beavers constructed 16 new dams.  Why? “I don’t know,” Vanessa responded.

But she hopes to find out!

Green Peak Falls.

Waterfall Mischief

Green Peak Falls was raging when we finally made our way down. The light of day was nearly gone, but I attempted to capture a photo of the falls anyway.

“I like Green Peak Falls better than Alsea Falls,” Vanessa remarked. Then turned and wandered over to the water’s edge. Vanessa was in her element as she balanced on rocks and logs in search of beaver sign. “Sometimes you see chewsticks that came down the waterfall,” she sighed.

After a few minutes of searching to no avail, Vanessa joined me, and we stared up at the cascading falls.

“The pool right above us…” began Vanessa, “I relocated a few beavers to a small tributary above it” She went on to tell me how the male of the pair (the female had died) would leave the release site and come down to the pool just above the falls. “He would hang out for days and then go all the way back up,” Vanessa reminisced. He never headed any further downstream. “Maybe he was too chicken to go around the waterfall,” Vanessa speculated.

I asked Vanessa how beaver typically handled waterfalls. “They do go around them,” she said. “Most of the time they will figure out a way to navigate around them.” However, she mentioned hearing about an unsuccessful beaver relocation where the beavers went over the waterfalls and died. “I have never seen the problem,” she said; “Maybe we have a better batch of beaver…”

Hopes for the Future

Darkness was really setting in now, so we decided to turn around and head back. As we walked, Vanessa talked more about her beaver dam ecology study and her goals for the future.

“We are in season four of data collection,” she said. After year five it will be intensive number crunching and analysis. The goal of the study is to help land and resource managers better understand the realized beaver dam capacity of a watershed and the factors that influence dam longevity at the individual dam and beaver site scales. According to Vanessa, the current popular model used to predict dam capacity tends to overestimate, making it seem like problems exist even when there isn’t one.

“No one knows how to best manage watersheds to promote beaver,” she continued. Our headlamps were now on guiding our way over roots and over puddles as we headed back to our cars. But more recently, Vanessa told me, there is money and interest in solving that problem. After the Labor Day fires, federal, state, and private land managers, in coordination with Vanessa’s lab, discussed the need to implement a landscape-level beaver study in western Oregon.  The study will ultimately include three replicate regions—the Western Cascades, the Coast Range, and Southwest Oregon—and use beaver activity surveys to document their distribution throughout these areas, in addition to other methods like radio-telemetry to track beaver movement and colonization responses to forest disturbances.

Ultimately, through this study, Vanessa hopes that some of the most basic questions about beaver may be answered, like what they need to survive, and how fire and land management may affect them.

Beaver Believer

Vanessa and I continued to talk as we walked in darkness. And before long, we were back at the trailhead and heading home. 

Having spent the evening with Vanessa, I really got a sense for her passion for her work, as well as her ability to be discerning when it comes to beaver science. Many people make the false assumption that if we can just get beaver back everywhere on the landscape, we will be okay. They will fix our problems—from habitat destruction to water conservation to even climate change.

But as amazing as beaver are they can’t fix the damage humans have done to the planet. They aren’t superheroes. Though they probably would look cute in a cape. And just like the rest of the planet, beaver have and will be affected by the dramatic changes in our climate and forests throughout the Pacific Northwest. 

So, as nice as it is to sing beavers’ praises, it misses the mark. To truly appreciate beaver, we need to understand them. That is the first step. And we aren’t there yet. But with the help of people like Vanessa, we might finally learn to walk the beaver walk.

Hike with a Field Geologist

View of Broken Top and one of the Green Lakes

I am constantly amazed by the power of water to sculpt the landscape. From glacially carved canyons and deep V-shaped ravines to massive floods capable of eroding and depositing sediment over 100s of miles—water in its various forms has shaped the Earth in profound ways.  The impact of water on the landscape can be seen all around us. If we know where to look.

Luckily for me, I arranged to meet up with Hal Wershow, a geologist and expert on reading the landscape, to help me better see and understand water’s influence in the Pacific Northwest. 

Naturally, we headed to the Cascades to a popular hiking spot in Three Sisters Wilderness called Green Lakes.

Hal in his element, enjoying the views and excellent geology!

The Hike

  • Trailhead: Green Lakes Trailhead
  • Distance: 9 miles round trip to first two Green Lakes
  • Elevation Gain: 1,100 ft
  • Details: This trail is very popular and was heavily trafficked until permits were put in place in 2021. A Central Oregon Cascades Wilderness is required from May to September. The trailhead is easily accessible and there is ample parking. A pit toilet is available at the trailhead.

Opening the Flood Gates

The path hastens along next to a fresh flowing creek lined with conifers and dotted with colorful wildflowers.  A few puffy white clouds floated past us overhead as Hal and I began our hike from the Green Lakes Trailhead.

The ground was level with baseball-sized pieces of pumice and other volcanic rocks scattered between bunches of vegetation. “Fluvial is the term we use for sediment moved by water,” explained Hal. The rounded rock and flat ground are signs that water flooded the area in the past.   

This, of course, begs the question—what happened? Short answer—No Name Lake.

You see, No Name Lake was formed by a glacial moraine, or an accumulation of unconsolidated rock, that was carried in and left behind by a receding glacier from the “Little Ice Age” of the 1800s. Then in the 1960s, an unexplained breach in the moraine occurred resulting in a flood. Perhaps some ice or rock had fallen in the lake generating waves that overtopped the dam causing it to fail.

Interestingly, the source of the flood was reported by Bruce Nolf, a geology professor at COCC at the time—a position Hal now occupies.

The waters from that flood would have washed into the area, Hal explained, carrying sediments and debris all the way across the highway we had just driven in on.

Snow Going

It wasn’t long before Hal and I, following the creek-side path, entered a more densely wooded area still blanked in snow. It was early summer and winter snow still lingered in large patches on the trail.

Snow accumulation in the Cascades is incredibly important in the Pacific Northwest. As snow melts it seeps into the ground slowly through pores in rock, becoming part of the groundwater. This water eventually escapes back to the surface through springs that feed our streams and rivers. The lag time between precipitation, snowmelt, and water resurfacing is important helping ensure water supply even in the drier parts of the year.

Snow fields were abundant along the trail.

Spring Forward

Hal told me about a project he is doing with his students at CCOC where they are studying the time water spends underground—also called residence time.  Referred to as the “Spring Monitoring Project,” Hal’s students are locating and gathering samples of water from springs in the Central Cascades near Bend. Then they are sending the samples to a lab for stable isotope dating to determine the residence time of each spring.

Stable isotope dating is used for a lot of applications—to date the age of fossils, archeological artifacts, etc. Elements, like carbon and hydrogen, have a different ratio of their respective isotopes depending on conditions and can change over time. For example, all living things contain a ratio of C-12 to C-14 that is constant, but once an organism dies, C-14 will decay predictably, changing the ratio. This change in ratio allows scientists to determine the age of tissue containing artifacts.

Spring water works in much the same way but uses different isotope tracers to figure out how long water has been underground. The time spent underground varies a lot. Water can remain underground for minutes to thousands of years.

“This research is important, especially in the light of climate change,” Hal explained. With increased drought conditions coupled with increasing demands on water resources, it is important that we understand how much water will be available each water year. Springs with long residence times may be more resilient to climate change.

Rushing Waters

Hal and I continued to crunch over frozen hills of snow, watching out for snow bridges, as we continued to pick our way alongside Fall Creek under a canopy of mountain hemlock and fir.

Eventually, we passed by Fall Creek Falls in just a little over half a mile and took a moment to appreciate the raging white waters as they rushed down a short rockface. Fall Creek and its falls are fed by the same waters that fill Green Lakes which, in turn, are fed by glacial and snowmelt from South Sister.

Waterfalls are another example of the force of water on the landscape. Water is an agent of erosion, but not all materials erode equally. For example, most sedimentary rock erodes easily, while others, like igneous rock, granite, are more resistant. Waterfalls, like Fall Creek Falls, form when there is a difference between the materials that make up the streambed. Essentially, the material below the waterfall eroded more easily than the material above it.

We continued to trace Fall Creek’s flow further upstream, the trail trending uphill through some switchbacks, eventually crossing the creek on a narrow log bridge.

Walk on, Rock On

As we walked along the path, Hal pointed out some of the different rocks found along the trail. All the rocks we saw were igneous rocks—formed from cooled magma.  

In general, igneous rocks can be divided into two major groups based on their silica content—mafic rock and felsic rock. Mafic rock is low in silica (45-55% silica) and is generally darker in color. The lava is less viscous (due to its low silica content) and erupts smoothly, as gases readily escape and don’t build up generating the pressure needed for an explosive eruption. Dark grey basalt is a classic example of mafic rock. 

Felsic rock on the other hand is high in silica (65% or higher silica) and tends to be lighter in color. The lava is much more viscous and stickier making it difficult for water and gases to escape. The result is a buildup of pressure and more explosive, violent eruptions. Pale tan or pink rhyolite is a classic example of felsic rock.

Light grey andesite is an intermediary (55-65% silica) between mafic and felsic. Andesite rock has enough silica to produce quartz crystals, so it often has a “salt and pepper” appearance.

Disorganized

However, the chemical composition of igneous rocks is not the only thing that determines their final structure. For example, rocks exposed to oxygen may become redder; rocks that form under the Earth’s surface grow larger crystals; and rocks formed during explosive eruptions may be more fragmented.

One of the most common rocks Hal pointed out on the trail was pumice. Chemically, pumice is like any other rhyolite rock, but because of the conditions it formed in, pumice has some unique qualities. 

Pumice is formed during violent eruptions of very viscous rhyolite lava that is very high in water and gases. When ejected, the gases escape rapidly and the water evaporates and expands, causing the lava to become frothy. Pumice is a disorganized rock—formed so quickly that there was no time for it to crystalize. Hal called it “volcanic glass.”

The resulting rock is an incredibly light, vesicular rock with the reputation of being able to float in water.

Slow your Flow

However, one of the most striking rocks seen on the trail isn’t pumice, but obsidian—a shiny, (usually) black rock, generally known for its use in arrowheads and other edged tools. The cutting edge of an obsidian tool is sharper than a surgeon’s steel scalpel. 

Not too long after crossing Fall Creek, part of the 2,000-year-old Newberry lava flow comes into view—a massive wall of rhyolite—much of it in the form of obsidian. The wall is a spectacular feature for the next few miles, hemming in Fall Creek on the opposite bank from the trail.

The wall of rhyolite starting to come into view.

Hal explained that obsidian, like pumice, is also rhyolite. However, unlike pumice, obsidian is not the result of explosive eruptions, but rather viscous lava that exudes slowly from volcanic vents. Just like pumice and volcanic ash, obsidian has no crystalline structure and is also “volcanic glass.”

Hal described the lava flow as being so slow that the movement would have been imperceptible to the human eye—we are talking less than a few meters per hour.  The flow would have also been cooler and not like the red-hot magma seen erupting from volcanos in Hawaii that tend to be mafic lava flows.

Lakes O’ Plenty

Hal and I continued to hike uphill through the forest, crossing several smaller creeks as we went. Eventually, we reached a sign with a map indicating we were about to enter the Green Lakes Basin. 

Early in the hike, Hal told me that there were several ways lakes can form. A glacial moraine is one way, like the one that formed Broken Top’s No Name Lake. A lava flow dam is another. Green Lakes is an example of a lava-dammed lake. From the map you could see where the lava flow displaced the creek and cut off most of the area above, creating the basin. 

Hal also pointed out the areas where water is flowing into Green Lakes. Not just water, but sediment too. They are being filled up, Hal explained. The addition of sediment means that Green Lakes will not be around forever.

“Another 1,000 years and they won’t be here,” Hal stated emphatically.  

Stopping to check out the Green Lakes map and sign.

Composite

Past the sign, the first of the Green Lakes comes into view. Flanking the blue-green waters are two massive peaks—South Sister and Broken Top.  Like sentinels, they tower above Hal and me. While at the same time, seemingly close enough to touch.

Both South Sister and Broken Top are stratovolcanoes, also called composite volcanoes—named for the varying nature of erupted materials that build their steep cones—anything from lava to ash. The formation of a stratovolcano is a process of building up and tearing down. They are known for violent eruptions where large amounts of their mass may be ejected into the air—sometimes leaving a large crater. Mount St. Helen’s is a composite volcano. Mt. Mazama, where Crater Lake now stands, is also a composite volcano that blew its top over 7,000 years ago.

Fire and Ice

However, as Hal reminded me, volcanism is not the only powerful force at work in the High Cascades. Ice—in the form of glaciers—is also a powerful agent of change in this volcanic landscape.

South Sister, with her tall dome shape retained, is still active—with recent eruptions dating back only a couple thousand years. In contrast, Broken Top is a long-extinct volcano—last active over 150,000 years ago. Since then, Broken Top has been roughly hewn by glaciers leaving its summit a jagged pile of rock and eruption crater exposed. Glaciers are moving ice, capable of abrading and polishing down rock, creating steep-sided hollows, and leaving behind sharp peaks and ridges. Hal pointed out some of the features formed by glaciers on Broken Top, including a cirque, horn, and arete.

Glaciers can still be seen on both Broken Top and South Sister—though they are much smaller and fewer than just a hundred years ago due to anthropogenic climate change. Staring up at South Sister, I asked Hal how to identify a glacier well enough to tell it apart from snowpack. “Crevasses—deep breaks in the ice formed as different parts of a glacier travel at different speeds—are one key difference,” Hal responded.

But Hal also noted that Glaciers can be very difficult to spot. So difficult, in fact, that only a month earlier, a “new” glacier was discovered on South Sister by Oregon Glacier Institute, an organization with the goal of identifying and monitoring Oregon’s glaciers. And by “new,” I mean new to science. “Glaciers tend to be in areas that aren’t very visible,” Hal warned, “making them difficult to locate.” 

Heavily eroded Broken Top

Alluvial Fans

Continuing our hike, Hal and I followed a trail that put us closer to the base of South Sister. Here we reached a deep water crossing and a view of one of the alluvial fans that South Sister’s meltwaters created stretching out in front of us.

An alluvial fan forms when terrain suddenly becomes less steep, like at the base of a mountain, and the water flow less restricted. As the gradient is lowered, the water flow slows and spreads out, dropping sediment in a fan or cone shape.

Earlier in the hike, Hal pointed out a “mini-version” of an alluvial fan where steep flowing drainage of water slowed near the trail as the path of the water flattened and the water was unconstrained. Though perhaps not as dramatic as the large alluvial fan in front of us, the principals are the same. When water slows, sediment drops out.

Hal and I considered crossing the creek to get a better look at the first fan, Hal even attempting to balance his way across some unstable logs, but instead opted for an adventure around the second Green Lake and past the third to the alluvial fan on the far side of Green Lakes.

Round We Go

As Hal and I made our way around the largest of the Green Lakes, we kept a lookout for more geological treasures.

The snow continued to be a bit challenging at times, but we treaded carefully along the narrow trail. 

Before long we spotted signs of an ephemeral spring. Though no water was rushing forth from the Earth, Hal pointed out the eroded channels, changes in vegetation, and exposed roots—all indicators that water had flown forth at some point during the year.

A bit later, Hal spotted a perfect example of high silica, rhyolite, and low silica, basalt sitting side by side on the trail.

Rhyolite to the left with basalt to the right.

Breach

Eventually, we made it to the bottom of the alluvial fan. Hal explained that there was evidence, at least in part, that the fan was a result of a breach in a moraine-dammed lake further up the mountain. The plan was to head off-trail and follow the alluvium up to see if we could reach the moraine lake.

Almost immediately after heading off-trail, Hal started pointing out the changes in terrain. Like a kid-in-a-candy-store he had me looking at the rock that now littered the ground.  “No pumice!” he exclaimed.

Instead of pumice, the area was filled with volcanic rock that looked speckled—with larger crystals embedded in a finer grain. A “porphyritic texture,” stated Hal—formed from lava that cooled slowly below the surface before rapidly cooling above the surface.

The “fresh rock” signaled to Hal that the lava bed we were walking in was from a different eruption than the pumice and lava flow from earlier.

Fresh volcanic rock!

Signs of a Flood

Hal’s excitement continued as we picked our way up the drainage—the area was literally awash in signs of past flooding.

For one, the size of the rocks changed—smaller rocks gave way to larger rocks—as we moved up. Hal explained that this was expected, as smaller rocks can be carried by the floodwaters farther than larger rocks, which would have been dropped closer to the breach.

Larger rocks also piled up along the edges of the now-empty flood channel—forming natural levees. Again, Hal explained how the energy of the floodwaters would have dissipated toward the edges, dropping these boulders into place.

Hal also noted how the forest looked different in the flood zone. Looking beyond, you could see a lot of taller trees, but within the flood zone, there were only small trees. Trees in the area would have been toppled by the floodwaters. The smaller trees, Hal explained, would have sprouted after the last big flood.

Flow Banding and Glacial Polish

Hal and I continued to pick our way over larger and larger rocks. Along the way, we saw some more fun geological features in the rock.

One such feature was a large rock near the edge of our flood channel that looked striped or banded. Hal explained that each band was really the result of different flow rates in the lava that cooled to form the rock—a phenomenon known as flow banding. Flow banding occurs because there is the shearing force between the layers of lava causing them to flow differently relative to one another. 

Hal’s geologist mini-figure sitting atop a flow banded rock.

A bit later, Hal pointed out another rock.  This one was smooth with some well-defined grooves. Unlike the flow-banded rock, the lines in this rock were formed from a glacier. When glaciers pass over rock, Hal explained, they carry gritty sediments that will abrade the rock, polishing the rock smooth.  If a larger rock is stuck in the glacier, it will carve deeper grooves in the rock as well.  The overall effect is called glacial polish. Hal suggested thinking of it like sandpaper—different parts of the glacier may have a different grit resulting in differences in the polish.

Survivor

We continued heading up the rocky drainage, crossing several snowfields. The rock levees are now as much as 10 feet tall in places. Looking back, beautiful views of the Green Lakes Basin periodically caught my attention. 

Apart from the snow, boulders made up most of the ground surface as we trekked upward. The young forest seen toward the base of the washout was nonexistent.  But what we did find were remnants of a vegetative past.

At one point, Hal and I saw a log stuck in the sediment that sparked some interest. Organic material, like the log, can be dated using either radiocarbon dating or dendrochronology. Radiocarbon dating would provide the apparent age of the tree, a decent estimate of age as far as geological events go.

Hal recording video of a log stuck in the sediment.

However, one of my favorite spots on our hike was where we passed a live tree that had somehow survived the floods. Though a bit disheveled, broken and stripped of bark on one side, it was beautiful in its own way. We stopped for a while by this tree, breaking for water. Standing there looking up at its worn trunk I was drawn to its ruggedness. It’s history. It’s story.

A Story

Hal and I never made it to the glacial lake to see the breach. Logistics didn’t allow for it. We did, however, see its effects.

The story of the Earth is one of constant change—often slow but punctuated by quick, sometimes devastating, alternations. Hiking with Hal reminded me of this.

Powerful natural forces that shape the planet, like water, make change inevitable, but also knowable. The story of our planet unfolds as we read the geology. And, like a tree battered by floodwaters, it is one of beauty and resilience.

The survivor!

Hike with a Dune Ecologist

View from one of the dunes in Pacific City, Oregon

There is something otherworldly about walking among the dunes on Oregon’s Coast. Walking from crest to crest of these rolling hills of sand feels akin to walking atop ocean waves. With each step the sand shifts underfoot, and you wonder if you just might comfortably fall into a deep crystalline sea.

Despite the strangeness of the sand dune landscape, dune ecosystems are common along Oregon’s Coastline (though not so much elsewhere). Formed following the last Ice Age by the erosion of the sedimentary rocks of Oregon’s coastal mountain range, Oregon’s dunes are sculpted and shaped by the seasonal influences of water and wind and the surrounding terrain. The result is a menagerie of dunes of varied shape, size, and expansiveness; some only a few hundred feet long, hedged in by headlands and other obstructions, while others stretch 10s-of-miles along the coast creating places like the Oregon Dunes National Recreation Area near Florence.

Given the ubiquitous and curious nature of dunes, it is no surprise that these large sandy masses, have been, and continue to be, influenced by people.

When European settlers flocked to the Oregon coast to establish communities in the late 1800s, they were immediately met with the challenge of living in a dynamic sand-swept environment.  Rather than retreating, settlers managed the sand with what they considered the best weapon in their arsenal—European beachgrass. European beachgrass has been used extensively throughout the world for erosion control. Oregon is no exception. European beachgrass is now a defining character of Oregon’s Coastal Dunes, influencing not only dune formation but also dune ecology.

To better understand the story of dunes in the Pacific Northwest and the ecological significance of European beachgrass and another non-native grass, American beachgrass, I met up with Rebecca Mostow, dune ecologist, at Bob Straub State Park near Pacific City for an interview and hike.

The Hike

  • Trailhead: Bob Straub State Park Trailhead
  • Distance: approximately 1 mile
  • Elevation: minimal
  • Details: Plenty of paved parking at trailhead. No fee for parking. There is also bathroom with flushing toilets. There are signs and a map posted at the trailhead.

It was a cool spring day when I met up with Rebecca for our hike and interview. A marine layer of clouds hung low in the sky, threatening drizzle, but the weather remained mild and dry. After some brief introductions, Rebecca and I headed out along the back dune trail, or Marsh Trail, at Bob Straub Park with plans to eventually cut down to the beach. 

Rebecca Mostow standing on the crest of one of the vegetative dunes along the trail.

Rich and Varied

As we made our way down an alley of shrubs and trees that line the entire back dune trail, Rebecca told me a bit about her background.

Rebecca’s undergraduate work was at Oberlin College, where she studied biology and plant systematics.  She also got involved in a variety of different research projects, from an HIV vaccine research internship to an invasive snail survey.  Her work continued to be rich and varied after graduation as well. She even spent some time on a tiny island with half a million sea birds and only two people for company.

However, it didn’t take long before Rebecca’s passion for plants drew her back. Even during her time watching sea birds, she admitted that she couldn’t help but notice the plants.  “I made a baby flora of the island,” she remarked. She also worked for the BLM in Nevada, Carson City district, on plant conservation before ultimately ended up in graduate school at Oregon State University in Sally Hacker’s Lab.

Intentional Introductions

Even now, walking along the trail, Rebecca was drawn to the plants surrounding us. She admired the new shoots of the spruce trees that grew along the trail, impressed by their symmetry. “See the little pattern,” Rebecca exclaimed, “a Fibonacci spiral!”

As we continued along, however, another pattern became apparent, at least to Rebecca’s trained eyes. “All of the plants we are looking at were intentionally planted altogether,” she explained.  European beachgrass was planted to help stabilize and build dunes, Shore Pine to provide native habitat, and invasive Scotch Broom as a nitrogen fixer.

“They were trying to engineer a coastal forest,” offered Rebecca, as an explanation.

Shore Pine, Scotch Broom, and European beachgrass growing together along the trail.

Unstable

As mentioned previously, sand does not make the development of permanent human settlement easy, or in some cases possible. By vegetating the dynamic, shifting sand system that was once present in the area, it was converted into a more stable system. But at a cost.

Rebecca explained that many species rely on open sand for habitat. Species, like the Western Snowy Plover, require open sand for nesting. The Streaked Horned Lark is another species reliant on open sandy areas.

So, though sand stability is great for human habitation, it does result in a substantial loss in habitat for other species. Both the Western Snowy Plover and the Streaked Horned Lark are threatened species under the Endangered Species Act mainly due to habitat loss.

This Grass is not like the Others

I have never been very good at identifying grasses and grass-like plants. Beyond remembering the saying: “sedges have edges, reeds are round, and grasses bend their knees to the ground,” I have very little experience with grasses and couldn’t begin to tell species apart.

However, walking with Rebecca along the dune trail, literally lined with beach grass, it wasn’t long before I received an education.  

“This is our native dune grass,” Rebecca chimed, pointing to a blue-twinged blade. She went on to explain that in addition to the color of the blade, there are many other characteristics that help distinguish American Dune grass, Leymus mollis, from the European beachgrass, Ammophila arenaria, that was brought in to build and stabilize dunes.

“The leaf blades are so much wider, and it has a more prominent midrib” than European beachgrass, said Rebecca.

Rebecca examining a patch of beach grass.

The Pits

And then there are the pits. Okay, so they aren’t exactly “pits,” but if you look at the point where the leaf and stem meet, you can see something called a ligule, a thin translucent-white tissue growth found at this junction. “The ligule is the armpit hair of the grass,” said Rebecca partly in jest, as she bent back a leaf. But it is also one of the most surefire ways to differentiate between beach grasses. American dune grass has a ligule that is short and flat. European beachgrass has a ligule that is much longer. When you need to tell grasses apart, “Just look at the pit hair!” Rebecca exclaimed.

Growing Underground

After my ligule tutorial, I asked Rebecca why European settlers on the coast planted European beachgrass instead of our native Dune grass.

 “It is our native grass,” responded Rebecca, “but it does not build dunes.”  She pointed to a patch of American dune grass growing just along the trail. “It doesn’t grow very densely,” she explained.  Each stem of American dune grass was spaced out a bit from the others. In contrast, European beachgrass is “super dense” allowing it to better capture sand and trap it in place.

“Look, these three stems are all the same plant,” Rebecca pointed out.

“It is amazing when you start to dig down,” explained Rebecca, referring the propagation of beach grasses. Even the native “dune” grass spreads via underground stems called rhizomes; they just send shoots up at longer intervals. It is the underground growth that truly makes European beachgrass a great dune builder.

Not Exactly Invasive 

“Would it be considered invasive?” I asked at one point as we walked along, referring to the European beachgrass’ ability to spread and compete.

To be considered invasive, Rebecca explained, a species needs to meet certain criteria. “It has to do significant damage to the environment, human health, or the economy.” For example, “Scotch broom is a listed invasive weed,” said Rebecca. “It is causing a lot of economic damage.”

European beachgrass is not listed, because though it has some of the traits of an invasive species, including negative ecological impacts, it doesn’t meet the criteria.  It benefits people in many ways, so it is difficult to say it is “causing harm,” even when some native species are being impacted.

Structure of a Dune

At this point, Rebecca and I hit a junction, and we agreed to cut down to the beach. But before we headed down, Rebecca explained a bit about the structure of dunes.

“We are on the crest of the foredune; the dune closest to the ocean,” said Rebecca standing at the highest point of the dune we had been walking behind. Behind us is the backdune and looking out toward the ocean is the toe, which slopes down toward the ocean. There can be many waves of dunes behind the foredune, rising and falling just like the ocean, “and they are all covered in grass.”

Views looking out over the backdune to the ocean

Varied Vegetation

“Backdune to toe, the density of grasses will change,” said Rebecca. And you can see other differences in other vegetation as well.  Where we stood near the crest of the dune, we could see pearly everlasting, beach pea, native strawberry, and what was dubbed a “fun little thistle-y thing” growing between the blades of grass on the sand. 

Not only that but, the species of beachgrass growing in an area also influences plant biodiversity. You see, in addition, to European beachgrass, American beachgrass was also introduced to the Pacific Northwest Coast to stabilize and protect coastal communities. However, for whatever reason, European beachgrass was introduced in the south and American beachgrass in the north, creating different beach grass ecosystems. 

The differences in biodiversity between the American and European beachgrass systems is something that Sally Hacker’s Lab has studied in the past. When the lab compared the biodiversity of these dune systems, it was found that European beachgrass supports greater plant biodiversity than American beachgrass.

Two Ammophila Species

There are many additional differences between American beachgrass (Ammophila breviligulata) and European beachgrass (Ammophila arenaria) that make each type unique.

A. arenaria also has stems that are skinnier, leaves that are thinner, and a long ligule. The grass blades grow densely together; instead of sending out lots of lateral shoots, A. arenaria grows more vertically.  In addition, A. arenaria “like to be in one clump together,” said Rebecca, allowing them to “accrete more sand” and build tall, steep dunes.

On the other hand, A. breviligulata has thicker leaves and stems and a short ligule. The grass blades grow further apart; instead of growing tall, A. breviligulata sends out lateral shoots and grows horizontally. According to Rebecca, a dune field of A. breviligulata is large and “hummocky.”

Hybridization

Though historically European beachgrass was dominant primarily in the South and American beachgrass in the North, on the Central Oregon Coast, where Rebecca and I were hiking, there is a point of overlap between the grass’s ranges. And, thus, an opportunity for hybridization, or the production of a genetic cross, between the two species.

“Part of my research is about the hybrid between these two beachgrasses,” said Rebecca, as she directed me down the toe and onto the sandy beach below in search of the first little hybrid patch she has been tracking. Rebecca explained that the first time the hybrid was “discovered” was in 2012.

“Discovered is a confusing word,” proclaimed Rebecca. “Some people from my lab were doing a survey and they found grass that looked sort of weird,” but it wasn’t until later, after finding more patches of the “weird” grass before it drew much interest. And later still before Rebecca was able to do the genetic work to confirm that what was discovered was a hybrid.

Taken for a Ride

We combed the beach looking for the “weird” hybrid.  However, instead of finding it. we noticed many signs of storm damage—large swaths of sand torn from along the toe of the dune. 

Rebecca walked over to one of the dunes and brushed away the sand from the base of one of the clusters of beachgrass. “Look here! You can see what it looks like under the sand,” she remarked holding a dense cluster of fibrous roots that branched out in all directions, connecting to other clusters of roots by underground stems.

“They erode from the beaches,” she said, “and it gets picked up by a wave and then gets spread from one beach to another.”

The Path Back

We continued looking along the beach, passing by the spot Rebecca recalled finding the hybrid in the past. The patch had since been washed away, perhaps to start up someplace new.

We headed inland toward another area Rebecca had GPS coordinates for, chatting along the way about her love of plants and how curiosity regarding invasive species led her to her work today. “Why do some plants get introduced and nothing happens?” Rebecca wondered aloud, reminiscing.

Rebecca’s passion for research was evident as we talked further. She told me how she got into genetic work in order to obtain higher resolution data that would allow her work to have a larger impact than in the past. “Genetic work is 100s to 1000s of data points,” she marveled.

Ultimately, Rebecca’s careful consideration of her interests and skills landed her in Sally Hacker’s Lab.

The Hybrid Problem

And then we were there, standing in front of a large path of hybrid beachgrass. “Here is its sweet little intermediate ligule,” Rebecca smiled as she pulled the leaf down on one of the grasses to reveal its “pit” tissue. “This is one of our wonderful patches,” she remarked, her gaze sweeping down at the bunches of grass that grew at our feet.

It was at this point that I asked Rebecca about the implication of the hybrid. “Is the hybrid a problem?”  I questioned.

Even though they are not native to Oregon, explained Rebecca, beachgrasses are providing a service to people that live in coastal areas by protecting them from storm surges and erosion.  However, “the two species produce different shaped dunes that have different value,” Rebecca explained. If the dominant species changes, that could mean a higher risk of storm surge to overtop the dunes, or it might not. She cited a 2010 or 2012 study that conversion to American beachgrass in areas where European dominates would create “a three-fold increase in overtopping risk.”

When it comes to the hybrid, there are a lot of questions to answer.

“What are its impacts going to be on the dunes? Is it going to build different shaped dunes? Is it going to take over areas of parent species?” Rebecca listed. “It’s kind of a dash to figure out the impact.”

More Invasive

There are also questions about how the hybridization might increase the invasiveness of the beachgrass species, potentially harming native species to a greater extent than the parent species.

“Hybridization can jump-start evolution in plants,” explained Rebecca. When separate species are put together you get something brand new— “a completely novel genotype!”

In addition, there is some evidence that the hybrid may be able to produce viable offspring, allowing for even more crossing of populations, increasing genetic biodiversity further. “Increasing genetic variation in invasive plants has been shown to increases their invasiveness,” said Rebecca.

To be Done

So, what can be done? “Can we stop or prevent the spread of invasive species?” I asked Rebecca, as we stood considering the potential impacts of her newly identified cross.

“There are a lot of layers to think about,” Rebecca suggested. Questions regarding who is being impacted and how will help determine an appropriate course of action. She used the example of cheatgrass, pervasive invasive grass in rangeland environments. The impacts of cheatgrass affect ranches and those that depend on the work the ranchers are doing, as well as the native plants and animals that live in the ecosystem.  Thus, figuring out how to prevent the spread of cheatgrass is a high priority in the west.

With beachgrasses, it is a bit different. Again, despite some of the ecological ramifications, the presence of the grasses is needed in human-inhabited coastal areas as protection.

However, there are some efforts to remove the beachgrasses and restore some of the native habitats that have been virtually eliminated on the Pacific Northwest Coast with the introduction of the grasses. In fact, Rebecca shared how her advisor, Sally Hacker, is involved in some research looking into how to best restore some areas of the dunes that aren’t critical to coastal protection.

“When you think about the impact,” said Rebecca, “we should all be on board to keep invasive species in their lane.” 

Three of a Kind

At this point, Rebecca and I headed back down the path toward our vehicles. Then, looking out in the distance, Rebecca pointed out a large dune that sat just in front of a line of houses.

“It is covered in hybrid,” she said, “and has all three species.”

Rebecca went on to explain how, instead of a natural system, the dunes in the area are actively managed—built up and planted by people—and suggested that we take a quick look. So, when we got back to the trailhead, a short walk later, we both hopped in our vehicles, and I followed her over to see what the fuss was about.

Upon arrival, we were able to find our first sample of American beachgrass with its short ligule. We also saw more European beachgrass, some American dune grass, and, of course, a lot of the hybrid.

Rebecca told me that so far, they have found more than 27 patches of the hybrid at 17 different sites heading North from Pacific City. The site we were visiting was the southern terminus of its extent so far.

And there was a lot of it! Rebecca pointed out the patches as we walked back onto the dune and looked around. There is so much of it, that Rebecca told me that they were in the process of training people to identify the hybrid as part of a Citizen Science Project.

We didn’t stay long on the managed dune, but Rebecca helped me gather a sample of the European beachgrass, American beachgrass, and the Hybrid. We lined them up and snapped a picture of all three for comparison.

A Bleak or Bright Future?

Looking at the photo now, with the hybrid placed alongside its parent species, I feel a bit like I am looking at a photo of a high school graduate with their proud parents.

We know a good deal about the European beachgrass and American beachgrass, they are settled in the habits of building dunes in the same way they always have, but the hybrid is something new—a fresh mix of genes with so much potential. The future of the hybrid could very well change the Pacific Northwest Coastline, for better or worse.  Many questions remain. And a lot of opportunities await. Fortunately, we have people like Rebecca here to help us understand its future.

Hike with a Wildfire Ecologist

Views from the open ridge top on Sterling Mine Ditch trail.

Fire. Red, hot whirls of gases set ablaze in the presence of oxygen. It is beautiful. It is dramatic. And it is dangerous. Right?

When I think about fire in my own life, phrases like “don’t play with matches” and “only you can prevent forest fires” spring to mind.  I imagine firefighters battling blazes, blackened trees, and billows of smoke filling the sky— in short, destruction.

This view of the fire is not uncommon. Over the years, fire has developed a bad rap. Fires have wreaked havoc on millions of acres of forests in the west. Thousands of people are displaced and even die each year as a result of fire. It has been suppressed and fought against for a good part of the last century.

We fight fire. But should we? 

After spending the afternoon talking and exploring the hillsides of Southwest Oregon with Chris Adlam, OSU extension forester, I am inclined to say “no.” Or at least, “not always” and “it’s complicated.”

The Hike

  • Trailhead: Bear Gulch Trailhead, Sterling Mine Ditch Trail
  • Distance: Approximately 4.7 miles loop with longer options.
  • Elevation Gain: Approximately 690 ft
  • Details: No restroom at the trailhead and limited parking.

Welcome to California

I met up with Chris on a warm spring afternoon at the Bear Gulch trailhead. Moisture hung in the air teasing us with the prospect of rain, but except for a sprinkle or two, we stayed dry. Dry is a common condition in the part of Oregon, which, as Chris expressed, is “much more common in California.” He described the place we were hiking as “oak woodland,” an ecosystem characterized by its hot, dry summers and little rain.

“As far as the ecology is concerned,” said Chris, “we are in California.”

It’s Complicated

Of course, there is one more thing that defines an oak ecosystem—fire! “This is a landscape that was made this way by fire,” explained Chris. But, as we started up the trail, it became evident that this defining characteristic had not been present on the landscape for a long time. 

“It looks messy,” said Chris pointing to patches of dead manzanita with new growth on top. There were also a lot of trees, including conifers crowded together along the path. “It looks terrible to my eyes,” Chris exclaimed.

Chris told me how he had found an old snag not to far from where we were hiking that showed “17 fire scars.” He explained that these scars mark the frequency of fire in the area. “It would have burned every 3-5 years,” said Chris. But that was the past. Looking around at the crowded hillside, Chris frowned. “This place hasn’t seen fire in decades.”

An Education

We moved up the trail slowly, taking in the scenery and flowers. Both of us botany nerds, we paused frequently during the hike to marvel at the rich plant diversity we encountered. After attempting to take photos of Henderson’s Shooting Star, I asked Chris to tell me a bit about his background.

“Well, my family growing up spent a lot of time outdoors,” Chris began. He recalled going birding and visiting the mountains. But “I never thought that much about it,” said Chris. Later, he became interested in sustainability and ecological restoration. “You can help fix them,” Chris said, referring to ecologically damaged areas, “And I thought that was very powerful.”

Mindshift

Chris grew up in France and moved to Canada when he was 19 years old. His earliest understandings of Native people had come from John Wayne movies. It was not until he moved to Canada, where “the tribes were very visible,” that he has his first encounters with Native people. He saw Native people fishing in rivers and interacting with the landscape. He was intrigued by their connection to the land.

Chris, like many from a western culture, had the perception that people are separate from nature. That you “go to nature,” rather than being a part of it. Stemming from this is the idea, he was of the mindset that “people necessarily hurt nature”—a contentious relationship.

However, Chris learned during his time in Canada and later in the United States, this does not have to be the case.

“There are many cultures that live sustainability not by separating themselves from nature but taking responsibility for their role as caretakers of their ecosystem.” It was this shift in thinking that really got Chris interested in fire ecology.

Cultural Problem

As we gradually reached the ridgetop, Chris spoke more about fire and how his interactions with Native people taught him to appreciate fire.

“I have been fortunate to learn from many tribes—the Karuk, Yurok Tribe, and Confederated Tribes of Grand Ronde…” began Chris.

“What have you learned?” I asked.

“I think about it a lot,” was his response. “Most important to me,” he concluded after much consideration, “is understanding how Native people treat fire differently.”

“We tried to fight fire; we tried to prevent it,” said Chris, but “you can’t control fire!”Chris went on to explain that the “fire crisis,” as he put it, “is a cultural issue.” “It is not a lack of science or knowledge. Not a policy support problem. It is a culture problem.”

“For Native people, fire is a sentient living thing.” While in the United States, it is legally considered a nuisance if it is not controlled.

FireKeepers

For centuries Indigenous people worked alongside fire to actively manage the land. Fires were set regularly before European settlement to maintain an open landscape ideal for hunting and foraging.

Walking along the ridgetop now, though, overgrown with vegetation and littered with deadwood, it was hard to imagine the open prairie ecosystems of yore. The views would have been incredible!

Botanizing

Despite the overgrowth, there were still some lovely remnants of the past landscape to admire, though I think Chris had a hard time getting past the devastation.

In particular, Chris and I admired the native wildflowers along the trail. Chris had a knack for identifying plant species

Many of the plants we observed were used by Indigenous people as food, fuel, or fiber. I asked Chris to point some out. He pointed to a fuzzy white flower with rounded petals that pointed at the tip—the Cat’s Ears Lily. “These have an edible root,” said Chris. Traditionally, they would have been used by a lot of tribes as a food source, he explained.

We also saw several examples of yellow Lomatia or biscuitroot. I had heard of the use of Lomatium to produce a flour that was shaped into transportable cakes. In addition to having edible roots, Lomatium has edible leaves and flowers, Chris told me.

“And then, of course, are the oaks!” exclaimed Chris. The acorns of the oaks were staple foods for many tribes who, at the time, lived in an oak-dominated environment. Once the dominant tree across the landscape, many tribes depended on and managed for, oaks and their associated species.

And what was used to manage the land for these plants? You guessed it. Fire.

Fire Dependent

Manzanita is another species used by Indigenous people found on our hike. “They made the berries into a drink,” said Chris.

At this point, we walked past a tall manzanita tree. Though beautiful to the eye, “ecologically they are an aberration,” said Chris.

Like other important indigenous plants, manzanita is a fire-dependent species. They need hot fire for seeds to germinate and plants to grow. Looking around the area, there was no young manzanita to be found. Instead, the shrubs were old and dying.

Manzanita was found all along the trail.

Ceremonies with Fire

Fire was also used in many tribal ceremonies.  Unfortunately, a lot of ceremonies were made illegal, Chris told me, “even until the nineties!” So, ceremonies were practiced in small groups or families. I asked Chris if he was able to observe any of these practices. He said that there are some you can go to but didn’t speak to his own participation.

Instead, Chris told me about one of the ceremonies observed by Indigenous people in Northern California until the early 1900s. The ceremony took place at the landscape level. One mountainside was set ablaze, and then another, and another. Eventually, the signal reaches the medicine man who is waiting in the valley bottom to “call the salmon” home.

At the same time, the landscape responds. As the shrubs and grasses burn on the mountainside, the water level is raised in the river. The smoke from the burn fills the valley, blocking the sun’s rays and cooling the water. All of these help the salmon return. “It is more than a lot of symbolism,” Chris proclaimed. 

Prescribed Burn

With all this in mind, Chris made the argument that we need to burn. And a lot more than we are doing right now. By doing this, we will not only revive the landscape but learn to appreciate fire and dismantle our need to control it.

“The most important thing to me is to do more prescribed burns. If we can figure out how to do that, then we will be good,” Chris stated.

A prescribed burn is a controlled process where landscapes are set on fire systematically. Prescribed burns are started from the top down. The landscape is lit with torches in lines and allowed to burn downslope until the fire burns out, then another line is placed below it and allowed to burn.

The whole process is easy according to Chris. “Regular people do prescribed burns,” explained Chris. “That is how we have done it over this last century.”

And prescribed burning has been used virtually everywhere across the globe. “You can go anywhere, people use fire.”

It wasn’t until recently that prescribed burning has, as Chris put it, “been given to the professional elite.” This change in responsibility is a mistake, according to Chris who has made it a goal to get people who live in fire-adapted landscapes involved in the process. “Everyone who lives in a place like this should get a chance to go to a prescribed burn,” he stated. It is part of our history and needs to be part of our future.

In Favor

We passed by another area filled with dead and down wood.  I started wondering why we were not burning more landscapes and I asked Chris about it.

“For a long time, we thought we could stop fire,” suggested Chris, but recently, “I think it is changing.” People are beginning to understand that prescribed burns are okay. In fact, according to Chris, eight out of ten people nationwide are in favor of the practice. People are getting it. They are understanding we need it. “It is not controversial,” said Chris, as some might make you think.

Overall, “we need to get people together to talk about it,” Chris suggested. “We need to agree. We can’t fight about this.” Being flexible and looking at the management options available, including prescribed burns, is key.

Several areas next to the trail were covered with dead and down wood.

Doing Nothing is Deadly

Chris and I reached a viewpoint or at least a partial one. For the first time in a while, we could see out onto the adjacent hillsides. “This place should be oaks and a few madrones,” said Chris. “We should see all the way out.” Instead, spindly orange conifers, sick from bark beetle infestation, dotted the crowded hillside.

A partial viewpoint. Looking out we would see many dying conifer trees in the distance.

“ These trees are a bunch of garbage and are doing to die !” Chris exclaimed looking around us. He pointed to a sickly sapling that was losing foliage and a tall Douglas-fir riddled with cones. “That one is dying,” he stated matter-of-factly.  Both losses in upper crown foliage and producing a lot of cones are signs of stress, Chris explained.

“If a wildfire came through it would do great things ecologically,” Chris continued. The area would be cleared of much of the sickly Douglas-firs, which would allow the oak tree to flourish. The fire would help any remaining trees better able to fend off insect attracts.  The manzanita and ceanothus would be able to go to seed. Grasslands would be reestablished.

 As I walked the ridgeline, I tried to imagine it—this place 100 years ago. I tried to see through Chris’ eyes what was lost and what one day may be found.

Fire Scars

Eventually, we passed an old snag, cracked and open so you could see inside.  Chris later called it a “cat-face.”

“This one had fire,” said Chris as he crouched down to get a closer look. Tracing his fingers across the black markings that punctuated its open face. “There are at least six here,” said Chris, referring to the multiple fire scars found on this one tree.

Each time a tree is burned it leaves a blackened mark. Given time, the tree will try to grow over the blackened area. However, like in the snag we found, it does not necessarily heal completely over, so that sometimes fire scars remain exposed for years to come.

The fire scars on this tree were close together, Chris estimated that the tree had been scared 3-4 times over a 20-year period. “Not to mention those that didn’t make a mark!” Chris clarified.

Legacy of Fire

As we continue along, Chris pointed out more examples of the legacy of fire on the landscape:

We saw another “cat-faced” tree—an oak—but this time its face was completely healed over so you could not see inside.

There was a notable area that was mostly clear of trees and underbrush, except for a few oaks with spreading branches. Though it was difficult to say for certain what had cleared the area, Chris had a sneaking suspicion it was fire.  “I would guess 1987,” said Chris, as a fire had been in the area that year.

“The oaks are doing great,” Chris pointed out as a testimony to the efficacy of fire. An understory of roamers fescue, a native bunch grass, punctuated scene.

An area cleared of underbrush and native grasses growing.

We also saw countless madrone on the trail, some that were huge having survived the fires of the past.  Others with multiple stems, creating a tentacle-like effect that was mesmerizing. Chris explained that almost all broadleaf trees, including madrone, will send out multiple shoots following a burn. Though some trees, like oaks, will thin themselves out, madrones keep their multiple stems. These octopus-like trees were a result of fire!

Legacy in the Landscape

Chris also noted how different areas within an ecosystem will have different legacies of fire. “South facing slopes tend to burn hotter and will have more oaks and fewer conifers, while cooler north-facing slopes will not burn as hot and have more conifers, Chris explained. In general, all areas “burn more severely on the upper part of slopes,” said Chris.

As we walked down into a stream drainage, Chris continued to ruminate on the topic. He speculated that the drainage would offer a different outcome when it comes to fire, perhaps acting as a fire stop and protecting the area from a severe burn. However, he prefaced that the steepness of the slope could also help spread the fire more quickly if it got started lower in the drainage.

Essentially, by looking at the contours of the land and the ecosystems that exist there, you can start to piece together a fire story.

Oh, the Plant Biodiversity!

Okay, so we talked a lot about fire on your hike! But another topic that came up time and time again was plants! “I aspire to know every plant where I live,” he admitted at one point. 

Considering I also have a strong affinity for plants, Chris and I spent a good amount of time distracted by the botany all around us.

We saw everything from milk vetch with its fuzzy seedpods to balsamroot with its bright yellow flowers. We saw paintbrush, wild carrot, sweet cicely, fern leaf biscuit root, nine leaf biscuit root, Henderson’s fawn lily, and larkspur, to name a few. Fragile fern was another hit along the trail. The biodiversity was amazing!

And the enthusiasm of Chris equally so. At one point, Chris charged off the trail to check out what he thought might be a cypress tree, only to find out it was a juniper. We were seeing species that you find in western Oregon, co-mingling with species from eastern Oregon.

It seemed like around every bend, was always another fantastic botanical find!

Of course, Chris could not help himself. “People don’t always think about it,” he said as we passed by another patch of manzanita, “It is fire that creates all this diversity.”

Not Clear Cut

As we came back up from the drainage, our views out became less obstructed than earlier in the hike. We could see hillsides of grasslands with ceanothus patches rising all around us. However, that is not all we could see. Off in the distance was a large patch of open ground—a clear cut.

Chris stopped in his tracks. You could tell he was not happy about what he was seeing. Though he admitted that timber harvesting was not his area of expertise, he saw some huge issues with how it was being done in Oregon. “Oregon has the least restrictive laws,” he started in on the issue. “You can clear cut 120 acres and if you throw a stick back in, you are all good.”

You could sense Chris’ frustration, which he tempered quickly. “There is a place for it,” he admitted, referring to Oregon’s coast range. It can provide “important habitat for bird species,” he went on, but this was not the place for it. “Dry forest is not good for this.”

Then there is the concern for fire. “Plantations burn more severely than older forest,” Chris said. Once the trees start to regenerate, all the benefit of fire protection that might come immediately following a clear cut is gone. “5 years you don’t have to worry, but once it is tall again, it will carry fire.”

Out in the Open

As we moved further along the trail and our views continued to improve until ultimately, we found ourselves in an open prairie ecosystem—face to face with the past. “I think this is a lot more what the landscape would have looked like,” said Chris.

Stately Black Oaks were spaced out at irregular intervals on the windswept hillside. It was beautiful. And it was the result of centuries-long practices of using fire.

Chris talked about how Indigenous tribes not only burned to maintain the open meadows ideal for hunting deer but how it was also used for pest management. For example, burnings occurred at night so moths that infest acorns would be attracted to the light and burn up.

Invasive Grasses

Amongst the fields of native grasses, there were also many invasive grasses, like medusahead, vying for space on our green hillside. Chris explained that a lot of the invasive grasses are annuals that go to seed each year, repopulate, and spread. The native grasses, on the other hand, are perennials that don’t seed every year, and thus are better adapted to frequent fire.   

Without frequent fire, the invasive grasses were encroaching on the lands of the native grasses—an all too familiar tale. But, as ever, Chris had the remedy—fire.  He explained that the annuals could be killed off with a well-timed prescribed burn, leaving the perennial natives to thrive.

Working toward Change

Despite the presence of invasives, Chris was in his “happy place” as we walked along the rolling hillside.

Chris and I talked about his work as we went. “So far I am working with landowners,” he said, helping them go through the steps of doing a prescribed burn. He also hopes to work with tribes in the area to bring fire back to the landscape.

Eventually, we reached the opening to a tunnel and a sign that read “Turning Water into Gold.” It was the opening to the Sterling Mine Ditch Tunnel—a hand-dug, 26.5-mile tunnel used to divert water for gold mining.  After poking around for a few minutes, we continued our conversation.

Changing Minds

“I want to bring people to more burn areas too,” remarked Chris, we began descending the trail through some oak woodlands and back to the road. He explained how people that experience fire are often traumatized. They cannot imagine the burned area ever being beautiful again. Chris wants to break that cycle of trauma by bringing people to a burn site so they can see “that not all is lost.”

Following a fire, life remains. There are still many live trees. Water flows through the streams. An entire seed bank of herbaceous plants, including brightly colored wildflowers, awaken and bloom.  Animals, like woodpeckers, reptiles, deer, elk, and bears thrive in a burnt landscape.

Chris talked about using nature journaling as a tool for self-reflection on the burnt landscape. “It is a project I am working on,” he said.  Nature journaling involved getting people to record what they notice in pictures, words, and numbers, generating questions, and reflecting on their own experiences.

By experiencing firsthand, the resiliency of the landscape to fire, Chris hopes to get people in touch with their own resilience. Experiencing “hard things” does not necessarily equate to a diminished existence, Chris explained. “You can come up all the better.”

Slow Burn

Chris and I continued to chat as we descended downhill through the woodlands to the gravel road and then back to our cars.  Upon reaching the road, we said our goodbyes.

I really enjoyed my time talking and walking with Chris. His passion for his work with fire and its ecological and cultural significance was evident throughout our time together. 

Since then, the idea that fire is a force to be valued and respected has been slowly burning in my consciousness.  To think of fire as something vital is a paradigm shift, but one that makes a lot of sense both ecologically and socially. It is easy to become alarmed by the fires that burn through the west each summer, but if we can start to see fire differently, we can learn to respond to fire more appropriately and learn to adapt.
