It started off innocuous enough. Shin high fields of green forbs, speckled with yellow inflorescences, grasses still peaking through their canopy. It was not long until I realized their true nature. Melilotus officinalis, or yellow sweet clover, an old enemy from my time in the tallgrass prairies of Iowa, more a nuisance than anything. Here in Buffalo Gap National Grassland, SD, they reign supreme, fed on the rains of last year, granting them the strength to dominate these vast fields.

Before we knew it, it seemed to swallow us up as it grew ever upward, the scent of honey thickening the air into a strange gaseous syrup. The M. officinalis stood at chest height with us, and as we ducked beneath its canopy to observe the rest of the plants hiding beneath it, we entered new worlds. A cover survey became a bushwhack through this seasonal midwestern jungle. Stem counts became a dive beneath vegetative waves. No step could be made without the fear of crushing the clover which enveloped our research plots. Their dominance does seem to be waning though, as the dry heat of the summer begins to transform them into brittle husks of their previous selves. And with this desiccation, I see hope, though I fear for the health of the other plants which have lived under the iron fist of sweet clover this year.

It is hard to believe that I have already been here in South Dakota for a month and half! My time here has felt like a whirlwind of change. In May I walked across a stage and received my Bachelor’s degree, and early the next morning I took off on my own in my hastily packed car, my course set for the Black Hills. From there, I hit the ground running at the Rocky Mountain Research Station in Rapid City, SD, training with the other seasonals on my team. A first-aid class, Forest Service driver’s license, and crash course in local plant ID later, and we were off to the field.
Our work takes us out of the hills into the fields of Buffalo Gap National Grassland where we hope to determine the effects of varying seasonal drought conditions and grazing on the the growth, physiology, and diversity of the mixed-grass prairie. When we are asked what we do, we have taken to telling people that we are trying to make sure that the cows, bison, and grazing wildlife have food each year. Which we are often reminded of as rancher’s cattle watch us from the distance. Most days are spent with our heads near the ground as we identify, count, and measure the various species which make up the grassland community. If you could not tell by my little introduction, this community is currently uncharacteristically dominated by M. officinalis, whose first-year seedlings last year benefitted from a rather wet season, resulting in the explosion of yellow we now see.
A herd of bison remind me that traffic in Custer State Park is not always wheeled.
I don’t spend all of my time hanging out in the grasslands though, as I live nearly smack dab in the middle of the Black Hills. In fact, my backyard is literally the Black Hills National Forest! A short walk out my back door and I am lost in slopes of ponderosa pines, a perfect escape when I need a little bit of space from the ever-present tourists who come to see Mount Rushmore, which is also only about 20 minutes from my house.
What I was not expecting though, was that one of the most striking features here would be the consistently picturesque clouds which form over the Hills. Each day seems to produce an uniquely beautiful cloud formation for us, though I am still learning what each is trying to tell us about the weather at that moment, as my now hail-dimpled car can tell you from experience. All the same, the rock formations here, which could often be described as cathedral-like in their own right, are often overshadowed by the vast mountains of water vapor which are built above them. I feel bad waxing poetically about them when there is still the Hills themselves to talk about properly, but there are still more blog posts to make, so I am sure I will get to it.

I am already thankful to be able to spend another season out in the field, and I am looking forward to continuing to learn from the rest of my time here with the RMRS!
Beginning work on a new project can be intimidating. Whether it is learning the rhythm of a new team, the native species in a new region, or just finding the right folks you need to talk to in a new office. However, that was far from the case beginning my work here at the San Bernardino National Forest (SBNF).
Day #1
My first week at the SBNF involved working alongside members from the Wilderness Volunteers, an organization providing volunteer opportunities to conserve America’s wild lands through collaboration with the US Forest Service, National Park Service, the BLM, US Fish & Wildlife, and others. It was, in my opinion, an excellent introduction as I was able to learn alongside the volunteers some of the processes involved in greenhouse management and restoration site maintenance. Myself, and the volunteers, got to see the journey native plants take as they transition from seed, to small yellow bullet nursery pots, to larger black bullet nursery pots, and eventually to outplants that are used in re-vegetating sites throughout the SBNF with the aim of establishing native populations in fire scar areas as well as areas degraded by invasive species and unauthorized OHV (off-highway vehicle) usage. I felt like I was watching the process through similar eyes as the volunteers; fascinated by California’s diverse and beautiful native species as well as the highly controlled protocols followed by the SBNF when growing and handling them. These strategies are in place to prevent the spread of the water-borne pathogen Phytophthora (responsible for root rot and other nasty plant infections) from the greenhouse to the wild populations we aim to protect and restore. Some of the species we handled on that first day in the greenhouse include: Rubber rabbitbrush (Ericameria nauseosa), Big sagebrush (Artemisia tridentata), and Scarlet bugler (Penstemon centranthifolius).

Day #2
After spending day #1 getting our fingers dirty in sterile potting soil, day #2 and day #3 had us trek to actual restoration sites in the SBNF. Both sites were located near my new home away from home, one of the Forest Service cabins in Lake Arrowhead, CA. Therefore, I got to start my days with a short morning walk through the Manzanitas and yellow pines from the cabin to our nearby designated meeting point where we touched base before beginning the days work. After discussing our given restoration tasks (weeding, mulching, and watering) we took a short hike through some of the tall invasive cheatgrass surrounding the camp site until we reached our destination, a small plot of land tucked in right next to the local water treatment facility. That first day was HOT (one of the many joys of summer field work in Southern California) so it was amazing to see what good spirits the Wilderness Volunteers were in despite the harsh working conditions. We spent an hour or so weeding some of the invasive grasses and weeds that began to establish in the empty areas of the site. I even got the chance to take a few swings at using a root wrench to pull out the deep tap roots of large established Scotch Broom shrubs (Cytisus scoparius)! Some of those swings were successful and others were less so, but it was a great experience in team building and utilizing different peoples skill sets to achieve a common goal. After weeding there was mulch to be spread in order to prevent new invaders from colonizing the open ground remaining between the native outplants. We spread a LOT of mulch (approximately 8.5 yds3) using wheelbarrows and 5-gallon buckets to transport our precious cargo from the large mulch pile to areas of the site where it would be spread evenly. Throughout this process I could hear the sounds of curious volunteers asking about different native species, noticing a random wildflower, or even a butterfly dancing in the light breeze. At one point we even found a stow away western toad in our mulch pile! I enjoyed watching the ground cover transition from small patches of light brown with grayish-tan sections of open soil to a vast field of rich pine brown dotted with the beautiful light gray-ish green of many of California’s native plants throughout.

Day #3
Day #3 with the volunteers was much the same as day #2 as we conducted similar restoration site maintenance at two additional sites around Lake Arrowhead, CA. These sites were bordered with large monocultures of Mountain Whitethorn (Ceanothus cordulatus), a native species which highlighted that not all natives are good for increasing biodiversity. Ceanothus is highly adapted to fire and thrives in disturbed areas with open canopy colonizing these areas and ultimately crowding out any other native shrubs, trees, or herbaceous plants from gaining a foothold post-wildfire. In addition to the ecological war for space waging at its border, this site had another unique challenge due to the plants being out-planted onto a hillside. This made moving mulch and water up to each of the plants a bit more laborious but just as with Day #2’s heat, the volunteers handled the harsh field conditions with a positive spirit that really had a way of rubbing off onto me and lifting my spirits in general. There is nothing like struggling a bit with a team to bring people together! Combining our brains and brawn together we decided the most efficient way of moving heavy buckets full of water and mulch up the hillside would be through forming a human chain and passing buckets from one person to the next so each of us only had to cover a short distance. This technique worked so well we were able to complete these sites and still maintain smiles on all our faces when we posed for a final group photo to commemorate the days work.

The unknowns of new beginnings can be intimidating, however working alongside all the folks at the SBNF as well as the volunteers who generously offered their time and energy for the sake of preserving native habitat truly made me feel welcomed and inspired! In total during my first week I assisted in using 1200 gal of water on outplants, maintaining 1 acre of restoration sites, and transplanting approximately 320 plants in the greenhouse here at the SBNF. None of this work could be completed alone, and I cannot wait for what the rest of this season has in store for myself, and this team!
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!

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.
Mexican Spotted Owl giving us the eye
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”.
Smoke from the South Fork Fire blocking out the sun
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 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.
Tally Lake (the second deepest lake in Montana) is east of Kalispell.
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.
Capture-and-release bumble bee surveys!
North Fork of the Flathead River
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 beautiful but deadly Zigadenus elegans
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).
The elusive Liparis loeselii
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).
Corallorhiza trifida, or yellow coral root, contains some chlorophyll and is only partially myco-heterotrophic
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.
Orobanche uniflora, or cancer root, is completely dependent on its plant hosts for food and water

A sedge meadow at Midewin National Tallgrass Prairie
Oh, the prairie, what a thing to behold! Grass swaying in the breeze, bees buzzing, birds chirping, maybe a nearby summer storm rolling in over the horizon. What do you feel looking at this photo? Tranquility, serenity, a sense of times gone by? Unfortunately, this peaceful facade conceals something more sinister. The seldom spoken truth is that the prairie is a place of unimaginable danger. As someone from the Sonoran desert, I thought we had it bad with all the spiny plants and rattlesnakes but at least our threats make themselves obvious. Needless to say, I was not prepared for the inconspicuous terrors that awaited me at Midewin National Tallgrass Prairie.
TOP 3 PRAIRIE PERILS
#1) TICKS
Disgusting. Terrible. Evil. Awful. There are no good adjectives to describe ticks. I have yet to find a tick on my person, but I know that eventually my luck has to run out and I rue the day that it does. They take the #1 spot because I really do not want Lyme disease or Rocky Mountain spotted fever! It’s pretty straightforward, they’re just plain gross.
#2) WILD PARSNIP (Pastinaca sativa)
This could be a very cool plant if you don’t think about how annoying it is. If your skin brushes up against wild parsnip it causes a reaction called phytophotodermatitis, which means that the affected area will develop blisters and burns when exposed to sunlight. I unfortunately experienced this first-hand, but I have to admit that I was a little impressed.
#3) HEMLOCK
Midewin has 2 varieties of hemlock; the very same poison hemlock (Conium maculatum) that did Socrates in way back when, and water hemlock (Cicuta maculata). According to the USDA, “water hemlock is the most violently toxic plant that grows in North America.” However, it only comes in at #3 because you actually have to ingest it for it to kill you. The point is, you probably shouldn’t put any random Apiaceae in your mouth.
Of course I’m kidding! So far my time at Midewin has been fun and informative, it is so different from Arizona but I’m enjoying the experience of being somewhere entirely new. Here are some things I’ve especially appreciated.
TOP 3 PLEASANT PRAIRIE THINGS
#1) FALL-OFF-THE-BONE SEDGES
You know that Carex are ready for seed collection when you can run the inflorescence through your fingers and the perigynia fall out like tender barbecue falls off the bone. It is so satisfying but maybe less tasty than actual barbecue.
#2) – COOL SEEDS
Wild Hyacinth (Camassia scilloides) seeds are small, shiny, black spheres that glisten like a beetle’s shell would. The seeds rattle cheerfully in the dry inflorescence so if someone wanted a makeshift maraca they might try visiting Midewin in June.
Camassia scilloides seeds
#3) – KILLDEER (Charadrius vociferus)
They’re funny! So far I haven’t been able to get close enough for a good photo or video but I will keep trying.
To close things out I’m including a relevant poem, this might be how I conclude every blog post but I haven’t quite decided. Check back next month to see if I keep this up, I guess! I hope all the interns elsewhere are having a good time.

I think it’s finally beginning to sink in that I work in a national forest. I’ve had a lot of jobs in my lifetime. Many of them were less than noteworthy- like the fast food places I worked at in high school. Others, I really enjoyed, like the ones related to my degree that I had in college. Perhaps the best of those, was the job I had working at the Crop Physiology Laboratory for my university. I have always enjoyed being in the lab, and in the greenhouses. But nothing compares to the national forest. It’s my favorite office I’ve had so far. Sure, sometimes it can be quite a walk to the nearest coffee machine, and the bathrooms aren’t always stocked with all of the amenities that one typically requires, but the views are spectacular- better than all of the high rise offices in New York City, no doubt.
My Office
Things are going really well here around the office. We’ve been able to get quite a bit done the last couple of weeks. At this point, I find myself wishing that the seeds would ripen faster. We are adding to our queue of harvestable populations faster than we can harvest them. Most of this is attributed to the fact that many of our species will not set seed until late summer. So we wait, and scout for more populations, and wait more. Certainly, we will be very busy with seed collecting once early fall rolls around.
Luckily, there are a few species that we have been able to harvest from this early in the season. There is nothing more satisfying than harvesting seed from a population that you have been monitoring. It’s so rewarding seeing the process from beginning to end: scouting the population, counting it, mapping it, photographing it, doing return visits on it, and then finally, when the time is right, harvesting it.
Last week, we collected again from a Lomatium dissectum species that we found our first day out in the field. We had monitored it for weeks. While we were happy that we were able to get seed, we were a little disappointed that we hadn’t found more harvestable populations of this species before they set seed. This particular plant matures and sets seed quite rapidly and early in the season. Luckily, before we were able to get too down in the dumps about it, we discovered the magic of higher elevation.
We knew of course that plants at higher elevations experience cold temperatures later into the year, and thus take longer to germinate, sprout and set seed than plants at lower elevations. But we hadn’t considered this in the context of seed collection. Not until we came across a huge, and still very much blooming population of Lomatium dissectum in one of the highest elevation areas on our forest. It felt like a second chance! This particular population appears to be months behind the population that we harvested last week. We will get to harvest more Lomatium dissectum after all!

Life is good. The forest is beautiful. Seeds are coming!
