Battle of the Bull Thistle

Another month has passed working with the folks here at the San Bernardino National Forest (SBNF). Time has flown, a testament to the fun I have had working in partnership with the Restoration team here. Despite the laughs shared in the field not every day has been a walk in the park, and this month was witness to a battle between us ecologists/botanists and the most angry non-native perennial herb one could imagine, Bull Thistle (Circium vulagre).

Stare down between myself (right) and some bull thistle (C. vulgare) (left) at Johnson’s Meadow.

We ventured out into the San Jacinto Mountains near Idyllwild, California arriving at a site known as Johnson’s Meadow. Equipped with serrated shovels, leather gloves, trash bags, and clippers in hand to go up against the large spikes of the thistles which are non-native to this riparian meadow nestled into the Southern California mountains. This area was identified as ecologically important due to the presence of a threatened species Scutellaria bolanderi ssp, austromontana a perennial herb native to California and found most commonly in wetland areas such as in the ephemeral stream that runs through this meadow.

Johnson’s Meadow also happens to be a grazing pasture for a local farmer’s cows, and therefore exclusion fences were put up around the identified population of southern skullcap (S. bolanderi) in order to prevent the cows from consuming this threatened species as a tasty snack. There are additionally milk weed populations (Asclepias eriocarpa) at the meadow that rely on native pollinators which are often just as enamored with the thistles as they are with the milk weed.

In order to combat the threat to local biodiversity that bull thistle poses, a group of forest service field techs, myself and Arturo with the CLM internship program, and Lance Woolley the district botanist for the San Jacinto side of the SBNF joined forces on a 3-day weeding spree. The meadow was full of tall, spiky thistle plants peeking up above the dense grasses and native California wild rose (Rosa californica) that filled much of the area. When we came up upon a thistle plant we first had to check if any of the flower heads had bloomed or gone to seed. If they had even bloomed (the purple puff sitting on top of that green spiky ball at the end of each stalk) we had to clip the flower head and place it into a trash bag for removal from the area. If the flower head had already gone to seed we did our best to remove these carefully without releasing the wind dispersed seeds into the surrounding areas. This process was difficult on its own due to the large spikes that cover every inch of a bull thistle from the stem, to the leaves, to the flower head. These spikes were often large enough to pierce straight through our pig-skin leather gloves. The only safe spot to grab a bull thistle is from the underground root once you’ve wrenched the sucker out of the ground. The process was made even more difficult due to bull thistles seeming preference of growing either next to huge patches of California wild rose (R. californica), stinging nettle (Urtica dioica), or if you are really lucky you can get the trifecta of all 3 pressed up next to each other!

In total after 3 days of work and a crew of forest service employees, interns, and a crew from the Urban Conservation Corps, we were able to remove the vast majority of the bull thistle biomass from Johnson’s Meadow. The population there had to have exceeded 500 and I wish we had kept an accurate count day to day of how many plants we removed but pulling thistle in the middle of July in Southern California is no joke, and we were lucky to remember our names at the end of the day let alone an accurate count. Regardless the district botanists Lance seemed to be pleased with our final result. The battle of the bull thistle ended with victory siding with California natives in Johnson’s Meadow primarily due to the intervention of people who care about conserving and protecting the diversity of our public lands! It was inspiring to look out and see how much we were able to make an impact, yet simultaneously it was daunting considering how many meadows just like this one exist that cannot be managed through human intervention. The battle of the bull thistle may have ended for this growing season in Johnson’s meadow, but something tells me the race for dominance between native and non-native species is just heating up.

New friends and Newts!

This month has been full of new plants, insects, and adventures! Seed collection has started to pick up in early July, so we began trying to scout as many populations as possible before they started to disperse. Dean and I found a gorgeous site for one of our target species, Penstemon newberryi, as well as a neat wetland with native pond lilies. I had to go take a look at the blooms!

We began exploring further away from the office and came across Pyramid Creek Trailhead, which happened to have a significant amount of our target species there, as well as gorgeous views of Horsetail Falls and the Desolation Wilderness. We have spent a few days going back there for phenology checks as well as seed collections! So far, we have collected Penstemon newberryi, Chlorogalum pomeridianum, Hosackia oblongifolia, and more to come soon!

My family came and visited me to see my new home! we explored the area and went to Lake Tahoe. They were so excited to see California again after moving to Idaho! We also went to see the Rubicon Trail, which is an off-roading trail that is some serious business. I don’t think my little Jeep is up to the task!

Dean and I have had the amazing privilege of assisting the Pollinator Team from Cal State East Bay. We collected data for a pollinator network for Lewisia kellogii and Calochortus clavatus var. avius. Learning more about pollinator work is fascinating, and I’m feel so lucky that we made some amazing new friends!

Yosemite!! I have been waiting for this for a while, and I finally got to go with Iris and Matt! We explored the park for a weekend, and it was absolutely fantastic. This park is very special and definitely worth the visit! We were there during a stormy weekend which was fantastic to see so much water and lightning!

Then, it finally happened. Dean and I drove to the north zone of the forest in search of some target species and stopped by a creek to eat lunch. There it was, sitting on a rock in the shallows… a NEWT! I have never seen a newt before, and it was magical. Best day yet!

On my free time, I went to Grass Lake with Matt, which is California’s largest fen. I have never been in a fen before, which the feeling is like a waterbed. Matt and I explored, finding some neat, rare Carex species, some little friends, and a rare mushroom that Dean collected for sequencing!

Dean and I went to go check on an Anderson’s Thistle site to see if seeds were ready to be collected, and Dean spotted something amazing! There was a large bright yellow bumble bee, that turned out to be Morrisons Bumble Bee which is a threatened species. So wonderful to see two of them in one day!

Finally, to end this month, we assisted in a training for Botrychium surveying. Seeing these in real life was pretty insane, they are smaller than I imagined! I am excited to now know what habitats they like to go look for them on my free time! We then finished off the day by watching a baby Saw-whet owl up in a tree.

And a little bug appreciation section!

July was amazing, I’m looking forward to what comes next!

Bees, berries, bears.

A favorite lunch spot of mine at one of our seed collection sites.

3 observations from this past month:

A thin layer of moss sits at the sill of the botany truck window. If you roll it down, you can run your finger over the soft mat of vegetation, sometimes still wet from rain.

Fallen trees contribute to the soft hills of the mossy understory. If one has been there long enough, placing your weight on its decaying wood will leave you finding yourself falling through to the other side, where water in some form awaits.

With the right timing and luck, you might witness black bears eating grass. Or berries and deer. Or rotten salmon.

Whether they know it or not, town is a safe haven for these young bucks, especially now that we have entered hunting season.

It is strange to think that I will only be in South East Alaska for one season, one summer. Especially when echoes of the year-round adaptations which have formed this rainforest are everywhere, so long as you take a second to look close enough.

Summer is go-time for everyone and everything here. Animals, plants, and Forest Service employees alike are all desperately trying to succeed in a frenzy of organized chaos, accomplishing tasks they’ve been waiting to do all winter long. Fishing, hunting, and foraging abound. Fawn learn how to walk on shaky legs. Plants expend energy producing colors and smells to tell the right pollinator where to land, and what animal it would like to poop out its seed. Fungi must spit out their mushrooms before it’s too late.

A common goal sweeps through the area and permeates the air like fog. It challenges us. Achieve, and prepare. Because, as the Starks would say with furrowed brows and foreboding seriousness—winter is coming.

It would be a mistake though, to interpret this goal as a reason to not appreciate the land, especially at the height of its liveliness, for all of its beauty and quirks. How else might we learn from it? For example. Large, fleshy fruits are not found in the plant diversity here. The Tongass National Forest Botanist (and my supervisor), Val, points out that this is likely the result of a short growing season, too little heat, and too much rain. All of which make such an endeavor not worth it to many plants. Why attempt to make a fruit that may not have enough time to fully mature? Or even worse, to put all your carefully stored carbohydrates into making one that could rot before it ever gets eaten?

Consequentially, I have picked more berries in the past month than I have my entire life. As of now, the list stands at: blueberries (three kinds), salmonberries, five-leafed bramble (a tiny kind of raspberry), (red) huckleberries, thimbleberries, (stink) currants, and (red) elderberries. Each one of these fruits measures smaller than my big toe—but (with a bit of plant anthropomorphizing,) this trend towards the tiny-and-mighty makes complete plant sense.

In this part of town, plants with fleshy, edible fruits know that any large animal able to carry your seeds to greener pastures will be on hiatus once the warm-ish weather leaves. So you’ll need to put out fruit, fast. Or at least as fast as you can, for a plant. Hence, small fruit. And a lot of them, to not only make it worth the bear’s while but to present perhaps a bird or mouse with the opportunity to take some of your seeds as well. Maximize your odds. Put lots of seeds in those fruits while you’re at it. Small fruits mature faster, and require less energy per unit. So even if one or two of them develops mold, it’ll hurt less. The risk of missing your opportunity to continue your genetic line is minimized. Plus, the ants will happily carry those leftover berries away, anyhow.

It is, figuratively and literally, the small things like this which allow me to endlessly marvel at the workings of ecology. Alaska is a prime example of how abiotic factors influence the dynamic of living organisms. How it has forced them for thousands of years to figure out a way to work in tandem with one another through stresses, all towards the basic endeavor of survival. Ecology reminds us that nothing which persists in nature does so in isolation. Especially not here.

This same reason is why Levi (my field partner) and I work to collect a diversity of seed. Because no one truly understands, at least not yet, how exactly that web of organismal relationships operates, or how intricate it might reveal itself to be if it is teased apart. And we risk losing it all, forever, if we continue to ignore that fact. From the berries, to the sedges, to even the stubborn seed pods of western meadows rue that refuse to ripen; there is merit in appreciating seeds of the entire native community, even if limitations force us to prioritize a subset. Who knows where we would be without them?

See you next month,

July is no joke

July went by in a flash. Time flies when your brain is preoccupied with worries about nearby wildfires. The month greeted us with a week of 105 degree days, making fourth of July plans slip away and canceling our pre-scheduled scouting trip to the Feather River District, due to a rapidly spreading fire that sprang up near Oroville, where the temperatures reached 114 degrees. 

Along with the heat arrived the sudden surge of work we had to do as seeds were quickly reaching maturation. We abruptly picked up the pace and had no choice but to begin collections in addition to being vigilant with scouting and mapping and correctly identifying pesky lupines before they all go to seed (Sam and I basically memorized the entire key to the Lupinus genus from how much we had to repeat the process). Inevitably we were going to miss the collection window for a few of our populations, but we tried our best to set our priorities based on each species’ phenology. 

Big-Leaf Lupine (Lupinus polyphyllus)

One of our top priorities was Beargrass (Xerophyllum tenax). Despite its deceiving name and appearance, Beargrass is not in fact a grass, but a perennial herb in the monocot Melanthiaceae family, which more closely resembles lilies. Beargrass is one of the most culturally significant plants on our list, as indigenous groups in the area have been utilizing parts of the plant for weaving and food for many years. In addition to cultural significance, Beargrass was at the top of our list for being incredibly well adapted to frequent burning, due to its hardy underground rhizomes. A rhizome, unlike roots, has nodes along it, allowing the plant to reproduce asexually instead of relying on pollination. This, however, could also be a part of the reason why we often come across a population that has not sent up flowers during the typical bloom period— instead of reliably blooming every year, Beargrass flowering time can be difficult to predict, as conditions need to be just right, and other reproduction methods are available to them. With all this in mind, it’s easy to understand our excitement once we finally came across a substantial flowering population! After plenty of dead-end scouting, Sam and I found one massive population beginning to fruit, and got to collect seed from this important species.

Following the Beargrass collection, there were many days spent making our way down gnarly mountain “roads” in hopes of finding more plants on our list before the seeds disperse. Last week this seemingly casual form of exploration, a routine in which Sam and I had become quite comfortable with, gave us a reminder that we should always be prepared for the adventurous nature of fieldwork. By ‘adventure’, of course, I mean all of the thrilling unexpected obstacles that get thrown at you as you spend more time in remote areas. The wake-up call came in the form of our first time getting our truck stuck in the mud, deep in the forest with no cell service, all while wildfires kept rescuers busy and hours away from helping. We had become too comfortable testing the limits of our truck. We had successfully passed through many sketchy-looking obstacles with it— what was one more tiny creek?

We got home, eventually, after several hours of waiting for help, walking around to try to get phone signal, and staring at the vibrant swirls of smoke in the sky. The Park fire had started a couple of days before near Chico, and was already reaching 100,000 acres around this time. All day we had been watching as the sky morphed into strange colors, with large plumes visible in the distance. The way the setting sun interacted with the smoke produced mesmerizing light distortions, illuminating the landscape in an eerie blue-green light as the sky remained dark orange.

A firefighter was eventually able to come pull us out of the mud, after dealing with yet another small fire that had popped up in the forest. We got out, and slowly made our way back home, driving carefully on winding mountain roads in the dark for an hour and a half. The whole way back we reflected on the incident, and gained a greater sense of respect and caution for the chaos that comes with peak fire season in northern California. Next time, we’ll get out and check how deep the mud is before attempting to drive through…

In search of plants in (and more things to love about) the Lake Tahoe Basin

              A couple of weeks ago, I cried about missing the summer storms in the Northeast. Not to say I don’t appreciate the constant 75-degree sunny days, but sometimes I long for the kind of rain that pounds on the windows, and thunder that shakes the house. The next day at work, it started to thunder for the first time since I’ve been here and stopped right after we took out lunch break. That day really cemented the importance of manifestation in the workplace for me.

              Lack of torrential downpours aside, the field season has been going great! The botany crew here at LTBMU has been finishing up our invasive plant removal for the season (aside from when bull thistle rears its ugly head…) and moving towards surveys. In our survey plots, we identify and record every plant species we find. Initially, this was really overwhelming, but it’s been a great way to learn more plant IDs. Our surveys have been concentrated in the burn scars from the Caldor fire in 2021 and are one way to document how the forest is regenerating from this high intensity fire. Although invasive plants have been popping up in patches here and there, the forest seems to be regenerating well, with many native species, like fireweed (Chamerion angustifolium) and quaking aspen (Populus tremuloides) gaining a foothold. In addition to documenting regeneration, surveying has helped Gerardo and I find many seed-source populations of target species, like spreading dogbane (Apocynum androsaemifolium) and Anderson’s thistle (Cirsium andersonii). We have also surveyed for several rare and sensitive species, like the veiny water lichen (Peltigera gowardii) and Bolander’s candle moss (Bruchia bolanderi). These surveys involved a lot of crouching in streams and laying down in bogs, but it was worth it to map these cute little plants.

              Last week, we took a break from surveys and seed scouting to work on an exciting collaboration with the Washoe tribe. On a stretch of beach on Skunk Harbor, one of Lake Tahoe’s most scenic shorelines, we constructed an enclosure for Tahoe yellow cress (Rorippa subumbellata). Then, within the enclosure (and surrounding area), we planted 300 small plugs of Tahoe yellow cress grown by the Washoe tribe. Hopefully, these little seedlings will go on to produce a thriving population. Tahoe yellow cress is an endangered species endemic to Tahoe, meaning it grows on the beaches of Lake Tahoe and nowhere else in the world. This little member of the mustard family is primarily threatened by recreation (trampling), so ideally our enclosure will allow the yellow cress to reestablish in Skunk Harbor. After finishing up the planting, we squeezed a quick swim into our lunch break.

              After a few weeks of surveys, scouting, and planting, I definitely feel more settled in. While I miss lush, stormy summers with firefly lit evenings scored by katydids, I’m finding new things to love about summer here in the basin: the sweet, caramel-like smell of Jeffery pine bark (Pinus jefferyi), beaches with perfect turquoise water, freezing alpine lakes surrounded with wildflowers, and the little groves of aspens that remind me of the trees back home.

The seeds are a comin’

The season is in full swing! We’ve been going to every corner of the Eldorado National Forest looking for new populations the past month-getting to know the area and settling into a routine. A few of our plants have begun to seed, and we’ve been able to get some fantastic collections so far. I have a feeling in the next month everything will go to seed at once!

Seeds of Asclepias cordifolia

There is something about collecting seeds that feels very human to me. Directly interacting with the creatures around me and being able to feel the potential for new life on my palm scratches something deep in my ape brain.

Aquilegia formosa in bloom

We’ve been paying attention to the pollinators as well. Watching the little world of bumble bees is a new way of thinking about the ecosystem for me. Absolutely fascinating! No pollinators, no seeds!

Poa on the Prairie

One of the most enjoyable activities so far at Midewin has been vegetation monitoring. We are collecting data to be used for floristic quality assessment, to monitor the quality and progress of our restorations. Each site that we monitor has several (4-5) 100 meter transects running north-south, each containing 25 points (spaced 4m apart). 1m*1m quadrats are placed at each point a random distance away from the transect (0-10m). At the start, a coin is flipped to determine whether the even random numbers will be east or west. Within the quadrat, every plant species is recorded, beginning with a .25m*.25m corner. After all species in the corner are recorded, all species present in the rest of the quadrat outside of the corner are recorded. Dead biomass (fuel) thickness is recorded at three points along the edge of the quadrat. Also, the species comprising 70%, 20%, and 10% of the dry weight in each quadrat are recorded. 

Conducting vegetation monitoring requires plant identification knowledge beyond what I’d ever employed before in everyday botany. You must not only be able to identify mature plants in flower or in seed (which can be keyed out even if you have never seen the species before), but you must be able to identify every seedling in the understory, which is a daunting task. They will lack the floral parts often necessary to be keyable, and are best identified by someone who has grown the plants from seed, seeing them at every stage of their life. Luckily, I have grown many prairie species from seed at my native plant garden at Northwestern, taking special care to document the species in their seedling phase and putting the pictures in a native plant guide for the future generations of my Prairie Cats Ecological Restoration Club. 

Dianthus armeria (Deptford pink) basal rosette. This one stumped us for a long time until we saw a fruiting stem coming from such a rosette.

Still, many of the specimens I encountered in the field were completely enigmatic. The wetland plots were difficult, containing many wetland plants I had little to no experience with (all those silly little Lamiaceae). Grasses also presented a challenge — I had only ever paid attention to the floral characteristics of grasses (I have attempted to key numerous grasses from family, but the keys usually rely on floral characters). Foolishly, I had paid essentially no attention grass vegetative characters. However, thanks to Anna, our great botany technician, I was able to quickly learn how to distinguish some of the more common grasses. Also, the previous horticulturist at Midewin, Eric Ulaszek, is somewhat of a graminoid connoisseur and a great field botanist, and he created a vegetative key for the grasses of Midewin.

One of those annoying little opposite wetland plants that feel impossible to identify. Our best guess is Laportea canadensis (wood nettle).

Every time I did quadrats, I derived a great amount of joy from finding the small, unobtrusive little things that you can expect to find in nearly every quadrat. For something like Poa pratensis (Kentucky bluegrass), finding it is almost a formality (it was in almost every single upland plot). However, they are small and often don’t show their inflorescences at the top, so finding them requires digging through all the small grass-like foliage at the bottom of the plot. I’d keep pulling little tufts of grass and looking for the Poas (also Poa compressa). And then all of a sudden… success! Poa on the Prairie! (This message is brought to you by the Don’t Kill Your Lawn Foundation).

Settling in

The whole crew from Ruidoso was still on the run during the start of July, down in district 3 meeting many other people and what they do as part of the forest but in a completely different life zone. I wish the circumstances were better but I’ve really been enjoying the ability to travel and see more areas in the state and understand the landscape a little bit more. Traveling through different cities, seeing different mountain ranges, different watersheds and how to get between them all has been really exciting. It’s been a bit of a transition moving to NM and learning a whole new ecosystem but it’s fun to be able to pull similarities from other places I’ve been to help with the process.

Visiting a “rival” nation forest.

Another important way to learn about the area is to work with people who have been here and worked on the land for a long time and are willing to share that information with me. So, before we headed back to our home district we stopped for a week in Cloudcroft to help the Institute of Applied Ecology do butterfly vegetation monitoring for the Sacramento Mountains Checkerspot Butterfly. It was amazing meeting people who are there to help us learn some new methods and tactics.

I finally feel like we are our own unit at the office now that we’ve returned. We are able to go out on our own and do our own thing while the rest of the wildlife crew does their own thing. They always report back to us about plants they found for us to go and check out and it feels like we are all part of a great team. I’m excited for our first collection (which we plan for today) and for the rest of the season after we have a bit more practice and get to try out some unique seed collecting methods.

Earth, Wind, & Fire (but mostly fire)

Fire season is early this year, and it has taken Oregon with a vengeance. Within one week of the first fire starting, every ranger district in Malheur had at least one large fire. South of our office, fire spans 170,000 acres and north of us, the fire is rapidly approaching 200,000 acres. In the two months that we’ve been here we’ve found only one population of Iris missouriensis, one of our key species, and it is now fully within the borders of a wildfire. For the past week, we watched the fire creep towards them and hoped, prayed, knocked on wood, and put all of our manifestation powers into the irises escaping unscathed. Unfortunately, that’s not how wildfires work. The smoke has also led to a couple lightning storms (which then led to more fires) with high velocity winds and some rain, though less than we would have hoped. All the elements are so prevalent to our daily lives here, it’s pretty cool.

Courtrock Fire boundaries as of 7/31 on WatchDuty.

Despite that blow, and the continuous blows of poor air quality, we have persevered. The fires have added an extra urgency to our collections and we are in go mode. With the help of the vegetation management team, we now have 22 seed collections which are rapidly growing. We’ve collected grasses and sedges and forbs, and paper bags of seeds have filled our perpetually insufficient storage space. The fires have cut into some other projects in the botany department too, so we’ve had double the amount of free hands to help. Silver linings! The growers that we will be sending our seed to need 500 grams of seed, which would definitely be difficult to achieve for some of these plants without so much help.

Now that we have so much seed, though, we’re starting cut tests, where we cut 100 seeds and count how many are germinable and how many are non-germinable to measure the viability of the population. We’re also counting how many seeds are in one gram of material and combining those two measures to figure out how much live seed we’ve collected. With the poor air quality, it’s been nice to have some work to do inside, but we’ve definitely been missing the full field days.

As of now we have over 200 scouting points on our map, 22 seed collections, and over 70 vouchers for potential collection spots.

Scouting points colored by whether they’ve been collected yet (Blue points are collected from, red points have not been collected from).

Overall, we’re doing good and are excited to keep collecting.

Until next time,

A Completely Incomplete Guide to Lupine ID

Month two in Plumas! Andrea and I are really starting to get into the swing of things now. We’ve spent the majority of our time this month working on seed collection which has been very satisfying. After learning the ropes for the first couple weeks, we’ve grown more confident and competent out in the field on our own. Scouting is still the bulk of our work but many of our populations are now ready for harvest. This may go without saying, but when monitoring populations for future collection, we want to be 100% sure on our species ID. With some plants like Veratrum californicum or Elymus elymoides, correct identification only requires a quick glance. However, with some other genera and species we really have to get into the weeds – if you will – to lock down that latin binomial. One genus in particular that is a priority for collection and a challenge to ID has been haunting our dreams and sometimes nightmares for all of July.

The Lupinus genus or Lupines are fairly ubiquitous across the Sierras and much of the American West. They come in all shapes and sizes, most often with obvious palmate leaves and whorled, long inflorescences of white, lilac, purple, blue and sometimes yellow flowers. They grow well in open areas and are nitrogen fixers like many other genera in the Fabaceae family, making them a great candidate for restoration projects in burn scars. Their fruit are pea-looking pods that are seemingly easy to collect and they grow in thick patches all across Plumas National Forest. All this makes the perfect recipe for seed collection. However, there are so many different species and identification has proven to be quite tricky. In the Jepson, the list of lupine species in California takes up seven whole pages and in our local flora, the Oswald Guide, they take up four. A search on Calflora yields 39 different species and varieties in Plumas County. All this means that we had a lot of learning to do when it came to differentiating between all these lupines.

Starting with the basics, we learned relevant lupine morphology and the various terms that would be relevant for identification. The aspects of the flower that are typically of note are: how glabrous or ciliate the keel is, whether or not the keel is covered by the wings, the width of the banner petal, how pubescent the banner backing is, the prominence of the calyx spur, the color of the petal, the length of the corolla, and I’m sure several other features. For the rest of the plant, we learned its important to look at, the height, the growth habit, how woody the stem is, the length or presence of stipules, whether or not the leaves are adaxially or abaxially hairy, the pattern and openness of the inflorescence, and the habitat its found in. Even when we figure out all of these features – to the best of our ever improving ability – some species are still unclear. For example, only a couple millimeters of stipule length might separate the decision to call population Lupinus andersonii or Lupinus albicaulis – two species which the Jepson describes as “morphologically indistinct”. The presence of an almost invisible patch of hairs on the inside of the wing petals could be the only signifier between L. argenteus var. heteranthus and L. arbustus. Without a doubt, there was a strong learning curve. Several weeks of non-stop lupine action did wonders for our identification skills. We went from a half an hour of keying only yielding more questions to fairly confident species IDs in a matter of minutes. The trick seemed to be constant exposure to different species and that repetition of the ID process. At this point, it feels like we have many of the Lupine key breaks memorized.

Unfortunately the satisfaction of gaining a new skill came with other unforeseen complications. Correct ID often meant that we could start collecting as soon as the seeds were ready. Throughout July, we watched as flowers shriveled and green pods emerged. The pods slowly turned brown and were ready for harvest. After putting so much work into these populations, we were very excited to finally do some collections. The first lupine collection for the year was a population of Lupinus latifolius var. columbianus that was growing along a remote mountain road. The pods were hard and brown, ready to pop. I cracked open the first pod looking forward to seeing those little pea-like seeds and was greeted with a large grub. Cracked another one, another squirming grub. The day went on and the pattern stayed pretty consistent – it felt like 80-90% of the pods had some fly larvae inside which had already consumed many of the seeds. Lupine tribulations just seemed endless. Fortunately, after collecting a few more populations of different species in a variety of habitats, we learned that not all lupines are that infected. I’ve come to accept that worms are simply a part of the lupine collection process and so many have popped out of pods into my face that I don’t even mind them anymore, maybe they are kind of cute.

Long story short, lupines are hard and will most likely remain hard but it was a satisfying challenge to throw ourselves at. Check out some other highlights from the month:

Stay tuned for August updates!
