Dolomite prairies house unique plant communities, the bedrock here is at or just below the soil surface. Like a slab of concrete or an abandoned foundation, the exposed bedrock looks out of place in this natural landscape. These prairies are seasonally wet; in the spring, rain and snowmelt fill the area with shallow water, and by summer, it becomes bone dry. These plant communities have adapted not only to the seasonally wet conditions but also to the high magnesium content of the soil due to the weathering of the exposed rock.

There are many rare plants that are restricted to the Dolomite prairies in Illinois, but one takes our time and attention like no other. Dalea foliosa, the leafy prairie clover, is a curious purple-flowered pea its flowers are arranged in dense spikes and it has the typical pinnately compound leaves. D. foliosa is federally endangered and is very much deserving of our time and attention.

According to NatureServe, there are approximately 8 occurrences in the state of Illinois. Habitat loss, fire suppression, and woody encroachment are still the driving factors of this species’ decline. Midewin is fortunate to have acquired 40 acres of dolomite prairie from a mitigation requirement of the neighboring ExxonMobil refinery. When monitoring and management began back in 2002, only 92 total plants were counted; today, we counted over 500. This population is far better now, but its isolation still poses a threat in terms of its genetic diversity.

We followed a very tedious monitoring protocol that involved counting vegetative and reproductive stems, aborted flowers, and stems browsed of each plant. We also collaborated with Fish and Wildlife to monitor two other populations on IDNR land. Midewin has worked hard to preserve this population, and it has paid off; however, this is never enough in a changing landscape. Threats of changing hydrology and freak accidents from the boarding railroad and refinery unfortunately remain a concern.

Photo Dump

I though it would be fitting to conclude my August blog with a collection of photos taken while seed-collecting and from our visit to the Chicago Botanic Garden. I hope you enjoy

Phacelia

Phacelia hastata sits there taunting me. One side still has its purple, curly inflorescence while the other side is dull brown – dried and perfect for collecting. A few more sit just 5 ft away from the first, but all are at least 10 feet above me. Phacelia loves to grow in hard to reach places where there is little competition and plenty of access to the sun. Perfect for the plant, but difficult for the seed collector. 

I grab everything I need from the truck – radio, paper bag, a glove – and glance back at the obstacle before me. This specific site was a steep, rocky slope next to the road made up of sheet rock. Slowly and carefully I start climbing the slope. Every two steps I took counted as one as the rocks shifted beneath my weight, but at least I was making progress. I sat low to the ground with my knees on the slope whenever I could in order to keep my center of gravity close to the slope itself and used my hands as additional support as I climbed. I made it to each plant and lightly ran my gloved hand along the dried fruits – allowing some to easily fall into my palm before throwing them into the paper bag. I had to wear a glove for this endeavor because the common name “Scorpionweed” for Phacelia hastata is very fitting as the fruits have hairs that are irritating and prickly to touch. I adjust my footholds and continue to make my way across the slope to the many Phacelia plants growing in this difficult terrain. I volunteered to go up to this height – my partners for today, Madeline and Stella, choosing to collect from the plants lower to the road.

I found this collection to be a fun challenge and enjoyed the accomplished feeling as I successfully transversed the steep slope. Some areas were easier than others. At some points I could stand up and carefully walk diagonally up the slope, while at other points I would slide down a few feet before having to find another path to go on. 

By the end of the collection time, I had collected half a paper bag of phacelia fruits/seeds and gotten covered in dust from the slope but felt very accomplished by overcoming the challenge. I was happy to have been able to get the genetics from the higher individuals to include into our collection and happy that I could climb this slope at all – one of the other sites which we wanted to collect Phacelia was even more difficult to climb and we had stayed to just the lower individuals because of this.

The Grasshopper

*Plop*. A grasshopper hops onto the windshield of our truck. We stop, but it seems as though it has no intention to leave. Slowly, we continue on our path. The grasshopper faces the same way that we are headed, his yellow body braced against the movement of the truck. We make our way past a small meadow and to another forested area when the grasshopper finally hops off of its own volition. I could not help but wonder if it knew what it was doing. If it was just using us as a way to create its own adventure and explore a new area just as we are using this opportunity to explore as well. I can only wish the grasshopper well on its future travels. 

Battle of Geum

For a few weeks now, my mentor, Victor, and I have been debating the identification of a specific Geum plant growing outside the office door. In the beginning of the summer, Victor told me that this one was ‘Geum macrophyllum’ which is one of the species on our collection list. At the time I did not question it, but this past month we ran into a couple other Geums that look very similar – especially now that they are fruiting instead of flowering. The three are Geum macrophyllum, Geum aleppicum, and Geum rivale. Rivale flowers are pink and nodding while the flowers of the other two are yellow – allowing easy distinction between the three when there are flowers present but all of their fruits are ‘spiny with achene beaks’ as stated in our plant key and look very similar at a glance. All three of these plants also grow in very similar habitats: moist sites next to rivers. Luckily, even with just fruits the rivale flowers still keep their purple sepals which is the key difference between rivale and the other two and also has the longest achene beaks. 

The next step, to separate out macrophyllum, is dependent on whether the lower portion of the style is minutely glandular or not at all. My partner, Tori, and I have had quite a lot of trouble deciding whether something is glandular or not throughout this summer – even with the use of a hand lens – and so while we do check for this step, we also looked to see if there were some other differences between the two. One of the Botany techs on the Helena side of the forest, Nate, responded to this question by saying that the macrophyllum receptacle is hairless while the other two possibilities in the key are not. Those other two being Geum aleppicum and canadense. Canadense is automatically crossed out as an option due to it having white flowers and no known cases of it living in the south west side of Montana – where we are collecting at. 

I took Nate’s shortcut and ran with it – informing Victor that our plant outside the door was indeed aleppicum rather than macrophyllum. Victor did not believe me at first – especially since Nate’s difference was not in the key that we used. He looked up pictures and tried to compare the species that way. In the past few weeks, he changed his mind on what species that plant was about 5 times before finally deciding today that I was right. The mystery Geum growing by the office door was indeed Geum allepicum – now added to our collection list along with Geum rivale. 

Day in and day out as we travel along the back roads of the San Bernardino National Forest the remnants of human festivities could often be found underneath the lush green pines, unauthorized campfire rings. The large dark stones and black ash contrasting starkly against the lushness of the forest announcing their presence and staining the earth black with soot. Oftentimes increasing in frequency during holidays such as 4th of July, Memorial Day, or Labor Day the sighting of these rings has brought continual frustration on our part as the summer heat continues to beat down and dry the flora surrounding it. While our main goal is seed collecting and target species monitoring another responsibility of ours is to destroy the rings to prevent further use, in hopes of preventing a fire from sweeping through the area. The process of destruction relatively simple, in that we disperse the rocks throughout the area and break apart the ash in an attempt to wipe its presence away for good. While the potential for fire spread itself is our main concern these rings oftentimes have large shards of melted or fractured glass in them that can be hazardous to others as well. Even after a site had been cleared of its rings the remnants of their presence still could be seen throughout like messy smudges drawn into the earth.

One site in particular known as Lytle Creek was filled with these unauthorized rings and in one day, we destroyed a total of 20 after a busy holiday weekend. Concerning as is, we discovered also that one of the rings was still hot to the touch even days after its previous owners had abandoned it. The last fire that ran through Lytle Creek was only a few years ago and was started by an unauthorized campfire ring such as this. While the continual finding of these rings proves frustrating it is rather beautiful to see how the forest regrows after a fire. Places that were once burn scarred or barren now begin to blossom again with native flora. During our drives through the various habitats in the forest we’ve stumbled upon a handful of burn scarred areas that are slowly recovering with time and restoration efforts. While it can be disheartening to see these beautiful habitats be abused or destroyed it is incredibly rewarding in playing a part in aiding in their recovery. During my time working in Big Bear with the restoration team I’ve taken part in two Green Thumb events on the forest that utilize both staff and volunteers to aid in restoring damaged habitats such as these. With the help of volunteers, we’ve been able to replant 100s of native species into areas that were once bare plots of earth. This work could not be done without the help of the volunteers that work in these events and we are incredibly grateful for the time they spend in helping us restore and preserve the forest for future generations to enjoy. Overall, it’s been a blast being a part of these restorations’ projects on the forest and I look forward to the month of September where we will be having a large volunteer event taking place that will involve the planting of around 400 plants!! Until then, I hope everyone is having a lovely time working out of their different locations and I look forward to reading your blogs!

About a week into August, we were asked to help the alpine botany crew with a species composition plot. Since I had started this job, I had been dreaming about working with the alpine botany crew. I knew very little about their job, but I knew they hiked into the alpine every day and that sounded amazing to me!

That first day with them we hiked above 11,000 ft which was the highest elevation I had ever been to by at least 2,000 ft. To put that height into perspective, the highest peak in Oregon in 11,200 and we weren’t even at a peak! The site was at a saddle between two peaks and had me in awe the entire next two days. I couldn’t stop thinking that the two alpine botanists had to be the luckiest people alive to have places like this be their office every day!

The species composition plot consisted of three vegetation transects that were about 36 meters long and we would log vegetation every 0.5 meters. At the end of each transect we would set up three 1 square meter plots and find what percentage each plant present took up of this square.

On our way down on the last day we saw a group of mountain goats. I learned that one of the main reasons the alpine vegetation needed to be monitored so closely in the La Sal’s was that the goats were introduced here as a game species, and they were monitoring what effects they had on rare alpine plants.

After working with the alpine crew for a couple of days we went back to business as usual: building fences, collecting Heterotheca villosa and scouting for Heliomeris multiflora. We don’t expect to begin collecting Heliomeris multiflora until mid September and are nearing the end of our Heterotheca villosa collection which meant we had a little extra time for other projects.

The last week of August, one of the alpine botanists had the week off and they requested me to fill in. I was over the moon excited! I was going to be helping with the rare plant surveys that they complete every day, which are smaller and quicker than the species composition plot I had helped with before. The rare plant surveys are either a single 10 meter or 15 meter transect, where we place four 1 square meter plots at equal intervals along the transect and mark where within these plots a rare plant is seen. We also do a pellet count to gauge goat, deer and elk presence within the study area.

The La Sals are on of only three areas on the Colorado Plateau where you can find true alpine tundra communities, making the plant life super fascinating. One interesting plant they study is called Silene acaulis and is a mossy plant that gets covered in tiny vibrant pink flowers. Studies have found this plant to live to over 300 years old! Another interesting species we saw was Erigeron mancus which is a little yellow button flower that we spent most of the week studying and is endemic to the area.

This was easily one of the best work weeks I have ever had! We hiked over 30 miles and gained over 8,000 ft in elevation total. The highest peak we summited was 12,600 ft with some of the most breathtaking views I have ever seen.

August is when I truly fell in love with these mountains. I can’t wait to summit more in September!

Cheers!

This month: a restoration story. One of water, salmon and seeds.

Seed collection is a necessary step toward restoration. But this month, we partook in another type of restoration. For one week, we partnered with the larger Tongass NF Fisheries crew and Ketchikan Indian Community (KIC), diverting and re-building a stream.

Toward the beginning of our season, I asked Val (our lovely supervisor), what restoration meant to her. She told me she sees restoration as a two-fold concept: 1. to repair damage we have done in our past, and 2. to enhance and advance natural processes that will eventually occur without human aid. This month’s stream restoration project channeled these perspectives into practice, thinking 100 years down-the-line.

Our large group of people, adorned head to foot in waders or their Grundens and Xtratufs, spent lots of time with and in the river and mud that week. We hauled over 10 logs into the stream, wrapping rope around trees and using blocks to weave the rope through and then drive the logs in. We dug over 10 trenches to place those logs, diverting stream flow and re-establishing the s-curves of the water’s movement.

It was empowering work. Rejuvenating and physically exhausting. It was an excellent group of people. And it was a beautiful thing to be able to see the fruits of our labor. It was also humbling to see the force and capacity of water, to acknowledge that we can dig trenches and place logs and watch the sediment fill, but the river will do its own work to restore, to re-story. This is a river’s restoration story, we are just the hands to help in the process.

(And in a couple of years, hopefully we have a seed-mix to spread along the stream in the aftermath).

All season, I have watched salmon runs swim upstream — swaying bodies moving in company with others against a strong current. While out collecting seeds at Ward Lake, (a common trail and accompanying campground area near town), mostly Spirea splendens (Rosy Spirea) and Carex aquatilis (Water Sedge), you could smell them before you could see them: rotting salmon on the lake shore. When I’d look down in the water and see their carcasses beginning to give way, I’d whisper: “good job. you made it.” Their struggle is all at once inspiring and heart-wrenching. As I bent down to strip seeds along the lake shore, I listened to the beating rain and their relentless splashing.

In late August, Mather and I backpacked the Deer Mountain Traverse, an alpine trail covering 18 miles and spreading along four peaks and a rocky ridge-line. Cassiope mertensiana (White Mountain Heather) and Vaccinium ulinignosum (Bog Blueberry), bursting with fruit, hung low to the ground. Arnicas and Gentians towered over them, tickling our ankles. I don’t believe I will ever get over how small and mighty alpine plants are. Our legs were tired, and our lungs exhausted. And even up there, nestled in the high mountains, water prevailed. Snow fields tapered into snow melt lakes and waterfalls funneled water down to lower lakes, rivers, streams, groundwater, ocean.

Alpine lakes, muskeg bottoms, puddles on pavement after it rains, the breeding grounds of rivers, and the ocean, broad and spreading. Water is everywhere.

August was a time of changing weather, new plant species to scout for, and a newfound independence for the seed girls of Moab. The weather cooled off quite a bit here in Moab over the past month, going from being in the upper 100s everyday to only being in the 90s, and some days we were even fortunate enough to see temperatures in the 80s! On our trips up into the mountains, we were met with daily thunderstorms and the occasional hail instead of the normal dry heat we had become too familiar with. Overall, we became more independent in our seed scouting and collecting and got to take part in many different projects this past month.

We began scouting for our third target species, Heliomeris multiflora, or showy goldeneye! This beautiful member of the Aster family that can be found at a wide variety of elevations ranging from foothills all the way to subalpine. So far, we have found the most Heliomeris at elevations around 10,000 feet. We have identified quite a few large populations, so now we wait for the seeds to mature and get ready for collection!

We have continued to collect seeds from Heterotheca villosa, or hairy false goldenaster, and we seem to stumble upon more populations of it everyday we are out in the field. Although it appears that the seeds of Heterotheca are beginning to pass their prime in most spots as we now enter into September, we are planning on making a few more collections before all the seeds drop. Heterotheca has been my favorite species to collect so far because I find harvesting these little puffballs to be highly satisfying. Is it just me, or do they remind anyone else of Horton Hears a Who? The only downside to collecting these puffs is that you have to be very mindful of the weather. We learned that wind is public enemy number one while trying to collect this species on a particularly windy day. One big gust of wind at the wrong moment and you could lose a lot of progress!

In other exciting news, we got to spend some time up in the alpine with the Botany Crew here in the Manti-La Sal National Forest. Hiking into the alpine was like visiting another planet. I found myself wearing three layers and still a bit chilly and hiking across snow in August! Our goal was to assist with alpine vegetation surveys and get some hands-on experience with vegetation plots and transects. I learned so much, though my favorite part was getting to see mountain goats for the first time as they ran up and down peaks and made it look so easy.

I have really enjoyed getting the opportunity to be involved with the different departments of the Forest Service here and can’t wait to see what new experiences come in September!

During my time in the Umpqua, I have learned a lot about the nature of seed and seed collection. As something that I had never really given much thought to before, I have picked up on quite a few things regarding the matter. Though not extensive or something that can possibly be used across the board, I caught myself this last month making a mental rule book for the dos and don’ts of seed collection. Noting the things that nature had to teach me, I learned along the way what was easiest, the best, or sometimes the worst way to go about a process.

1. Never force seed. One thing that has stuck out to me the most, and should perhaps have been the most obvious idea, is that that seed will freely give itself to you when it is ready. It’s the whole purpose and the thing it wants to do the most – be released in its time of maturity. So when walking up to a plant, I now take note of how easily the seed gives itself up to me. Do I have to force it off of the plant? Or if I move too quick, accidentally bumping the plant, am I in trouble of losing my collection because it has sprung away at the smallest of encounters. If so, chances are I can pass go and collect my $200… after a trusty cut test of course.

// note – I wouldn’t necessarily think of berries and fruits in this way.

2. Following that thought, I move on to lesson number two: Be careful where you tread and grab. The number of times that I have lost the seed that I was reaching for simply because I moved too quick, missing what I was reaching for or accidentally bumped a plant with my leg… embarrassing. Springy seed pods, such as the Aquilegia formosa, will have you flying seed halfway across your work area with the smallest of movements. While not all seed is positioned for a great launching, those that are require patience and precise work – and maybe a little less shaking from drinking too much coffee in the morning.

3. Avoid spiderwebs. Not necessarily a hill I’m willing to die on, but I can think of a few reasons to avoid spiderwebs. First, because of spiders, duh. The last thing I want to do is reach for a handful of material and have a spider or its web in my hand. Yuck. I don’t like it. I don’t want it. No thanks. Second, webs catch things. Mostly bugs, but sometimes other things too like seeds. Here in the Umpqua, one of our most treated non-native invasive species has a wispy seed comparable to that of a dandelion. There have been a few times that I have noticed these fluffy seeds caught in a spider’s web. For me, collecting spider webs full of other, perhaps unfriendly seeds is not worth it so I avoid it altogether.

4. South facing vs. north facing. Thanks to rocking climbing I knew that any rock, bluff, or thing facing south would be hotter than the north, and as a result, knew that any seed facing south would be ready for harvesting first (ignoring elevation). This is because the sun rises in the east and sets in the west, the south side of any object will see the most hours of sunlight in a day.

5. Work in designated lines. When working in groups, it is important to assign work areas within your collection site. I have found that working in transects works best. This allows for all areas to be covered. No accidentally missing plants. No double-picking. You are responsible for an area – you know where you began, you know where you stopped, you know how much you’ve collected.

Honorable Mentions

Don’t be greedy. Take your percentage, leave the rest, and trust that Nature will provide everything you are meant to take.

Don’t cry over spilled seed. Seed spilled in the wild isn’t really lost or wasted. It’s where it was originally meant to be.

Patient work, not speedy. Small collection species are tedious and require a lot of effort. Don’t give up on collecting early because it’s uncomfortable. Pay your dues. Take the time to do the work. Tomorrow’s collection species will probably be easier.

Walk around. Find the beginning or the end of a population to begin your work. Don’t start in the middle and make yourself all confused. Additionally, you might find something new that you missed before.

When da Vinci painted the Mona Lisa he described the feeling of a divine presence guiding every brushstroke.¹ Making this key felt sort of the same way. 

In the key I did not key many genera down to species-level because I feel that keying a grass down to genus-level often times suffices. Anything else just feels pretentious. I especially feel this way with the genus “Bromus”. I am of the correct opinion that, in an effort to make our jobs easier, all bromes should be combined into one species (the unibrome). 

Cheatgrass (Bromus tectorum) is a noxious weed invasive in much of the Western United States. But, there are a number of brome “species” already native to this area. If we combined all the bromes into one species then cheatgrass would no longer be invasive and we will save a lot of money by no longer needing to invest time and resources on invasive management for this species. As an added benefit, mountain brome (Bromus sitchensis) is one of the target seed collection species for myself and my co-intern. We are having some difficulty locating suitable populations for this species, but if mountain brome and cheatgrass get combined into one species then we could just collect cheatgrass seeds. This would save us a lot of time because the cheatgrass is everywhere, even in disturbed environments where you would expect to see mainly invasive species. I suspect the reason plant taxonomists have not thought of these changes is because they are cowards. Unfortunately, there is not a Nobel Prize in biology.
