June 2024

At a little over three weeks in the Malheur it both feels like I’ve been working here for years, and like I have no idea what I’m doing. We hit the ground running on our first day compiling data on our target species and have since been out in the field scouting nonstop. We’re looking for a series of grasses and forbs in the forest with large enough populations to collect seeds from for future restoration projects. Our primary focus this season is riparian species, so we’ve been searching through wet meadows, streambanks, and springs. As you can imagine, the mosquitos have been insufferable and seem to have a special affinity for my blood. Yet, we persevere! 

I’ve never lived in a town as small as John Day, and within my first 4 hours in the area, a man who called himself ‘the candyman’ gave me free fudge (creepy? maybe! But it was good fudge), four deer ran past me and crossed the street at the crosswalk, and at least six deer were laying around in our front yard. This may seem commonplace to those of you who grew up in smaller towns, but as someone who has only lived in cities, I was pretty pumped. If I didn’t know about the issues with habituation, they would be my buddies by now.  

We’ve had several run-ins with animals in the field. On our second day, we helped with a bumblebee survey and a bold little chipmunk posed for us for our entire lunch break. One week in, we accidentally herded a group of humongous cows for at least two miles because they couldn’t figure out how to move to the side of the road. While scouting in the Murderer’s Creek area, Ivy and I encountered wild horses. I knew they existed in the area from a little anecdote about them on one of our maps, but it was completely different seeing them in person. I’d never seen a group of horses all the same color together, and it was hard to believe they were real.  

In real news, our first few weeks have been very productive. We’ve identified over 75 populations of our target species, taken over 30 vouchers of suitable populations for collection, and started our first seed collection. An hour of collecting from a population of Ranunculus occidentalis yesterday gave us about 10g of seed. While this is a long way away from the nursery’s aim of 500g (a loooong way away), it’s a start!  

That’s all for now!

Until next month,

The landscape of the Chicago region has gone through extensive changes since the last glaciation. If the land was not covered in glaciers it was tundra. Over the course of millennia the climate got wetter and warmer creating a taiga filled with boreal flora and fauna. Then getting drier and warmer it slowly morphed into prairie. The recession of the glaciers created almost all of the notable geographic features around Chicago, moraines, drumlins, and eskers. The Great Lakes and glacial outwash make up significant habitats such as the lakeshore, dolomite prairies, and the sand along the Kankakee River. Each has their own slough of life that highlights the geological significance.

During the past 2 centuries European settlers have created the most significant changes in the landscape. Farmers quickly transformed vast amounts of prairie in to pastures and buried just as much with the plow. Today only 6,100 acres out of the 21 million that were originally here remain. Some of these remnants are still under threat from human development. Recently a gravel prairie remnant, Bell Bowl prairie, was destroyed by the Rockford airport for a parking lot. Many of these remnants are fragmented from each other only surviving along edges such as railroads, power line easements, and fence rows. The disjunction creates islands of habitat that many valuable species cannot survive in. Mead’s milkweed and Hill’s thistle have almost completely vanished from our region due to their need of genetic diversity to reproduce. Much of the fauna has disappeared due to human development. The Eastern Meadowlark has faced significant decline due to habitat loss. The Meadowlark needs the grasslands here, whether it’s prairie or pasture, it just has to be large enough to. The reintroduction of bison back to Illinois is one of the most significant events for restoration as they readily capture the attention and imagination of those ignorant to what Illinois is. An interesting plant we monitored while at Midewin was Buffalo Clover. The clover survives primarily along the trails of Bison because the trampling scarifies the seeds allowing them to germinate. However, the only grazers the clovers see are deer so the only way the population is surviving is human management with fire. While humans have destroyed and disturbed all but a sliver of our natural areas, we are the only way that our ecosystems can change and continue to survive.

Everything that has followed the training in Chicago has been a wild ride with some big ups and downs, it wasn’t all bad but it was definitely not how I pictured my first month of fieldwork (which I suppose is fitting for the job).
My first week in the Lincoln NF was amazing! The whole team consists of silly gooses and sweethearts which made acclimating to the new area much easier than I had anticipated. We spent most of the week tagging along with the wildlife crew on Mexican Spotted Owl and various Hawk surveys to get a better feel for the region and the types of terrain we’d be facing this season. We apparently got to experience a New Mexico Birder’s fantasy when we spotted a mating pair of Zone Tail Hawks and a Black Hawk within just a few hours of each other, and I had seen many pictures of the Mexican Spotted Owl, but it is not the same and getting stared at by one in real life.

I felt ready for the second week of work, we had found a good handful of plants we wanted to assess for collection and were ready to do some more in-depth scouting, but Monday didn’t quite turn out that way. We started the day like normal, and were invited to join on a night owl survey (which involved hiking with mice and getting a much closer look at the owls) so of course we were interested. This meant we took a good break after lunch to catch up on rest and were to return to the office at 4pm to commence the evening survey. We had heard of a small 5-acre fire starting that morning but didn’t think much of it as we heard no updates. I went to take a nap and rest up for the night’s adventures, but as soon as I lay down, a strong gust of wind blew my curtains open. This wind was immediately followed by sirens and helicopters.
I left my room to find the rest of my housemates already gathered in the living room, I asked if the sirens were for the fire and all they said was “look outside”.

It looked apocalyptic. We had a clear view from our front yard, and it appeared as if it were only miles from the house. We were on “SET” status, and soon we were on “GO”. We packed up all our belongings in less than an hour and we left. We were one of the first areas to be evacuated. I didn’t know what was going to happen but seeing the the mushroom cloud from 100 miles away was not the greatest comfort. We spent the rest of the week working from home and checking the wildfire apps every 30 minutes to see it reach closer and closer to town. It was devastating. Nearly all the areas we had just visited in our first week were within the red lines, and within the week, over 1000 structures in the area were lost. I honestly wasn’t sure if I was going to have a job after this, or if I would be moved to an entirely new place. But Ruidoso and the Lincoln team are a tough bunch.
By the next week, we were sent to the Guadalupe Ranger District which is about an hour from Carlsbad NM. We ended up here for a week and a half surrounded by rocks, rattlers and ocotillos that happened to be green and in bloom (which I’d never thought I’d see). This was a whole new adventure, we learned about new desert plants and had the opportunity to explore a cave not open to the public, as well as experience an oasis in the middle of the Chihuahuan desert that I would have thought was folklore if I hadn’t seen it myself. It was an amazing opportunity granted by the most unfortunate of circumstances.
We get to return to the Smokey Bear office this coming week, and this whole experience has made me unbelievably grateful for what I have and those around me. I am part of an amazing team and could not have asked for a better group to work with. I am more aware than ever of the importance of the work we are here to do and am ready to help the community I am so newly a part of in any way I can.

Moving: frequently underestimated

Moving always comes with unexpected problems. After living in Missoula, MT for the last two years, I moved up to Kalispell for this internship. I uprooted quite an extensive system of familiarity, but there are some connections that withstand the uprooting and room is made for new ones. I have had to regroup and reassess what relationships sustain me, and what resources and opportunities to pursue. The relationships built in human and ecological communities can both sustain and harm the player/actor and it is impossible in either world to live outside the web of connections. My co-intern and I have seen and learned a lot since we started a month ago, and below I share some stories of plants we encountered in their interconnected ecological webs, and the unusual and unique ways of life they devise to survive in their communities.  

Busy bees and toxic pollen

Flowering plants can develop intimate relationships with their pollinators, like the bumble bee. Some plants require a physical vibration to release pollen held tightly to their anthers, and bumble bees, unlike honeybees, can perform the essential “buzz pollination” that can shake this pollen loose (Dolan et al. 2021). Montana is a uniquely diverse state for bumble bees, with 28 species documented in Montana out of the 45 total found in North America (north of Mexico). This month we participated in the Montana Bumble Bee Atlas project, a community science project gathering data for tracking and conserving bumble bees (Bumble Bee Atlas). We traveled up the gravel road running alongside the North Fork of the Kalispell River (west of Glacier Park) to reach meadows of lupine and buckwheat flowers. The catch-and-release survey we conducted was a small data point in this comprehensive project aimed at sampling hundreds of locations across Montana.

Some plants may require buzz pollination, but at least there are several different species of bumble bees to do the job. The Mountain death camas, Zigadenus elegans, has only one pollinator: the miner bee. The death camas is flowering right now, and the plant’s cream-colored flowers, dotted with green nectaries, look inviting. True to its name, however, the entire plant is toxic. Everything from the bulbs to the nectar and pollen contain the deadly neurotoxin zygacene. All pollinators but the miner bee, Andrena astragali, would drop dead if they tasted from this flower. A single bulb is enough to kill a human. Why would a plant kill all but one of its pollinators? The answer lies in the usefulness of the toxin to the miner bee. The kleptoparasitic cuckoo bee lays its eggs next to the miner bee eggs, expecting a meal from the food cache the miner bee left for its own young. Once hatched, the cuckoo bee eats the toxic food cache, laced with zygacene poison from the death camas plant. Only the miner bee has an innate immunity, so the kleptoparasite dies, ridding the miner beehive of the pest. In return, the mountain death-camas gains a loyal, mutually codependent pollinator (Mitton 2022).

The making of a unique community: the fen and friends

Many of the rare plants we are searching for are encountered in wetlands, particularly fens. A fen is characterized by the presence of peat (sphagnum moss), a pH greater than 6 (neutral to basic), and a year-round supply of mineral-rich groundwater (Keddy 2010). The groundwater chemistry of a fen system determines the fen’s pH, with more basic fens considered “rich” in terms of species richness and more acidic fens considered “poor” (Wassen et al. 1996). Rich fens are often fed by groundwater running through limestone, which produces a bicarbonate buffer against acidity.

We surveyed a rich fen and a poor fen this month. The rich fen was a checkerboard of little microclimates, each inhabited by distinct species carving out little niches. We saw the rare orchid Liparis loeselii, a picky plant, that requires the convergence of many conditions: mossy tussocks to create microtopography, open vegetation, calcareous waters, and specific mycorrhizal fungi associations (Maris et al. 2023). Mycorrhizal associations are of particular importance to orchids. The dust-like seeds of orchids lack energy reserves for the embryo to germinate (Jacquemyn et al. 2017). During orchid germination, mycorrhizae send out hyphae that penetrate the cell wall and feed carbohydrates and nutrients to the tiny orchid. Without this intervention, the orchid lacks the fundamental building blocks to continue development. Different studies have shown the specificity of these associations, revealing the Liparis loeselii preference for a specific saprotrophic fungi in the Tulasnellaceae genus (Maris et al. 2023).

We also surveyed a poor fen composed predominantly of sphagnum (peat) mosses. The sphagnum mosses acidify and lower the nutrient availability of fens. Both the rich and poor fen contained Drosera rotundifolia, a sundew, but the poor fen contained larger patches. Sundew associate with sphagnum moss, which create floating mossy tussocks of desirable sundew habitat. The high-water table of a fen creates unique challenges for plant species, since nutrients from the soil are not easily attained. Sundew supplements its nitrogen needs by carnivalizing insects (Millett et al. 2012). The plants attract insects with a sugary, sticky mucus that coats the end of many little red stalks on their leaves. Once prey makes contact, the plant can move its tentacle-like leaves, a response called thigmonasty, to place the insect in contact with as many stalks as possible. The plant secretes digestive enzymes that dissolve the insect, and the leaf surface absorbs the nutrient-rich ex-insect soup.

Turning tables: myco-heterotrophic and parasitic plants

Almost all orchids are myco-heterotrophic at some point in their lifecycle and with maturity they produce chlorophyll and begin making food of their own. Some orchid species, like those in the Corallorhiza genus, never “grow up” and they remain fully to partially myco-heterotrophic throughout their lifespan. Myco-heterotrophy are reversed plant-mycorrhiza relationships, where carbon exchange goes from fungus to plant (Trudell et al. 2003). These plants are sometimes referred to as “mycorrhizal cheaters.” Lying in the subterranean darkness for most of their lives, these plants mimic their mushroom host’s life cycle, popping up from the ground only to produce a reproductive structure (Zimmer et al. 2008).

While Corallorhiza and other myco-heterotrophic orchids parasitize fungi, the plant species of the Broomrape family (Orobancheae) parasitize other plants. The seeds of Orobanche uniflora stay in the soil for years, lying in wait until certain chemicals released from nearby plant hosts stimulate germination. The seedlings put out haustoria, rootlike structures, which delve into nearby host root tissue, siphoning off water and nutrients (Kokla & Melnyk 2018). The Latin work “haustor” translates to “the one who drains” and these little vampiric plants have an apt common name: cancer root.
