Happy hunting season! We donned our stylish orange vests for a morning assessing demography and surveying plants at our last large prairie remnant. Lately there’s been all kinds of caterpillars out and about, including lots of woolly bears (one of which had no brown saddle at all, foretelling the harshest winter possible—gulp!)
We found plants 200 and 201 both flowering—just as they were in 1995, when they were first tagged. Though 200 produced only one dud this year, 201 prevailed with three lovely heads—just as it did when it last flowered, in 2016!
At lunch we enjoyed the rest of Stuart’s cake with ice cream, a lovely treat for a hot afternoon. Stuart may have voyaged back to Chicago, but we continue to enjoy the rewards of his efforts!
After finishing up in the remnants Riley and I returned to P1 to continue measuring. We collected grass seeds to broadcast this fall, and helped some common milkweed disperse.
After the excitement of yesterday’s goat herding adventure, Riley and I were happy to return to life and work as normal today, but that didn’t stop us from checking in with our favorite mischief-makers first.
We knocked out a small demo site before tackling harvest in P1 and P8 before lunch. After lunch we trucked out to P2 to harvest more heads. Though Echinacea flowering has concluded, the views from the plot are still gorgeous and bright with other flowers.
After heading back to Town Hall Riley bid me farewell and took off to the Twin Cities for his brother’s wedding. The mathematically-minded may have worked out that Town Hall’s population currently numbers just one person– me! (Unless you count the 72 ghosts in the basement, of course.) That’s a pretty lonely way to live though, so I convinced Baby the goat to come home with me and rematch for the WWE title.
It is with a heavy heart that we announce that one of our own, Amy Waananen, has passed from our midst to her other home in the Twin Cities. With the conclusion of flowering looming large, Amy has left us to continue her work at the University of Minnesota. Though some insist we may see her again roaming the remnants in search of plant tissue, I know this to be but a specter of our hopeful, grieving hearts. Town Hall mourns for the loss of our favorite corner-room occupant and master compost de-grossing expert.
And of course, life goes on. Even now, flowers bloom anew in the remnants. Plants first identified decades ago dutifully sprout through the wire loops of their tags and allow us to greet them as old friends. Perhaps next field season we might once again find Amy at Hjelm, syncing her visor, scooping up her clipboard, and striking out for the prairie.
Our morning began fairly quietly, with phenology in P2 and the remnants underway. We officially put the pulse-steady pollination experiment to bed for the field season, with no more styles left to pollinate. Chekov was resurrected and put to the test staking the corners of P9.
After lunch the entire team headed out to P9 to begin (and ultimately end!) measuring. We had a more exciting afternoon than any of us had anticipated; while measuring has its own thrills, no massive leaves or first-time flowering plants could compare with the thrill of accidentally sticking your foot in a Bombus griseocollis nest and hearing the resulting furious buzzing. I exclaimed “Uh—BEES!” and Jay and I scrambled back down the row we were working on. While I chose a two-legged locomotive strategy, I looked back and saw Jay army-crawling away from the threat. We both assumed Jay was a goner, and I continued my sprint southward.
The griseocollis were all buzz and no sting, and we returned to the plant we abandoned. There I found a katydid and a grub of some kind duking it out. The katydid was happy to climb around my arm for a photo op, and even happier to fall back into the duff and skitter away.
Before making our great escape Jay had spotted a mysterious orchid-like plant, which we lead Stuart to after he and John found another in a nearby row. We all puzzled over the plant and took careful note of its position so we can return to it later. Stuart suggested that errant seeds, micorrhizae or both may have traveled from the Chicago Botanic Garden to the plot on our equiptment, resulting in the plants establishing in the plot. Hopefully as it blooms and we get more opinions on the identity we’ll be able to make better-informed guesses about where they came from!
We were able to finish measuring every plant in P9, and will revisit the sea of white flags for rechecks in the near future!
Lately we’ve been having a surprisingly easy time competing with pollinators to harvest pollen for our pulse-steady experiment. What’s going on? Is it just the end of flowering or does the global pollinator decline have West Central Minnesota in its grasp? Only time and science will tell, but until then, please enjoy the anthem we composed this morning while collecting pollen.
Where have all the good flies gone And where are all the bees? Where’s the streetwise Hymenoptera To fight the high wind speeds? Isn’t there a winged beast Upon a fearsome breeze? In the morning I search and search And I hunt for bugs that plants need
I NEED A POLLINATOR I’m holding out for a pollinator flying in my sight She’s gotta be strong And she’s gotta be fast And she’s gotta be fresh from the hive I NEED A POLLINATOR I’m holding out for a pollinator in the morning light She’s gotta be sure And she’s gotta be soon And she’s gotta touch anthers and styles

Town Hall woke up bright and early this Saturday– or at least those of us left, since four of us are traveling this weekend! We had intended to perform the steady treatment in the pulse-steady pollination experiment before it got too hot and the bees beat us to all the pollen, but the end of yesterday’s thunderstorm system was still rolling through Kensington and we decided to wait it out. After the rain let up we finally arrived at the plot but found neither pollen nor pollinators. We futilely scraped wet pollen out of anthers until deciding to return when the sun came out.
A little over an hour later it had become a gorgeous day, and we were greeted by insects of all kinds.
Unfortunately the heavy rains and the cold front seem to have scrambled pollen production. The heads we bagged to harvest pollen from didn’t show signs of presenting pollen any time soon, and heads in P2 were lucky to have one or two anthers with pollen on them. We collected what data we could, but decided to hold off on pollination until tomorrow. Our expedition wasn’t for naught, however, because Miyauna found an Andrena nest!
We bagged a few more heads in the area around P2 so that tomorrow we’ll be able to harvest plenty of pollen. Though Miyauna found a tiny bee nest with ease, she was briefly puzzled when Avery disappeared into the prairie.
With Avery located, we headed back to Town Hall to nap and putter around doing chores. We celebrated the bee hole discovery by voyaging out to the DQ in Starbuck, which has the most charming signage and most savage mosquito population of any ice cream joint we’ve visited.
Today commenced with a group photo, now featuring the
eastern contingent of Team Echinacea!
The rainy weather limited our activities in the morning, but Stuart gave Jay, Julie and I a crash course in weeding sweet clover and bird’s foot trefoil, two weeds invading P1. The rain softens the soil and eases removal of tough tap roots. A little too much rain soaked me as I dug up my first trefoil, and after wrenching it free we fled back to Hjelm House for computer work and lunch.
After lunch we played an icebreaker game which, depending on whether you ask me or Riley, is called either Trainwreck or Shoe Game. We ran back and forth trading spots in a circle like a demented game of musical chairs and learned fun facts about one another, like who prefers to wear socks with sandals and who hates fishing.
Afterwards we trooped out to P2 to check twist ties and make
sure we know where to find and how to identify every flowering Echinacea angustifolia head. We visit
these plants about every other day and record every change in their condition. We
write down their afflictions and celebrate their reproductive success. In
short, we cherish them.
This is not the case for their close relatives, Echinacea pallida. The vigorous plants are The Enemy, and we advanced on them with gardening shears to smite their reproductive efforts. E. pallida is not native to Minnesota and could threaten the future of our familiar friend E. angustifolia through competition or outcrossing. We found that the severed heads are quite handy for fencing and flinging across the prairie.
Upon returning to Hjelm House Jay, Julie, Stuart and I took arms against a sea of trefoil and by opposing, ended them—hopefully? It’s tough to tell whether our efforts will be sufficient, as trefoil has a nasty habit of snapping off at the shoot and leaving behind taproots from which new growth springs.
Julie and I battled side-by-side with a root growing horizontally around a stone and the mother of all trefoil. I dug about 7 inches deep in the soil trying to extract the typically threadlike root system, but when it ultimately broke in my hands it still had the circumference of about a dime.
Being plant scientists doesn’t mean we love every plant, and
today was a better lesson in that than I’ve ever had before!
We started today by searching for flowering plants in Experimental Plot 2. The plants in the approach are really getting tall, and lagging on the walk in can mean losing the person in front of you!
Today I received a crash course in phenology. As heads begin flowering they progress through a number of stages that we record. Being able to distinguish between them is important to understand whether flowering has begun, or if we need to check back soon to record the start. Here are the four stages we saw today!
We all paired up to search the rows, which eventually resulted in Riley and I facing down our advancing teammates as we tried to thread the needle between the other pairs. We have to be careful about where we step in the plots so we avoid trampling plants.
In addition to plenty of plants we saw a menagerie of creatures in P2. My caterpillar adventures continue, and I am continually impressed by how many frogs live in the prairie! Back home in the swamp frogs are never a surprise, but here big leaps from little guys in the middle of the plot still startle me.
This afternoon we were visited by Tracie, Josh and Ruth, and over the phone Julie, Amy and I chatted with Lea about methods we could use this season. It was exciting to have new faces and voices around the Hjelm House! We spent the sunny afternoon sweating and rechecking flowering plant locations in P1, and weather providing we should be able to finish up P2 tomorrow.
We began our drizzly morning by outlining tasks for the week
and breaking into three main groups: tag-makers, flag-sorters and
hawkweed-exterminators. I volunteered to
write out tags with Drake and Amy, the latter of whom showed me the ins and
outs of writing standard tags that we’ll place during surv. We bopped to some
2000s pop standards and got a good chunk done, though I’m a little dismayed by
how much my fingers hurt from making just a handful. The fact that thousands of
these tags are bumping around in the wild is really an astonishing amount of
labor!
We came together after about an hour to begin flagging in
experimental plot 2 (P2.) We only had 4 corner flags and whatever plants we
could find to stake out one-meter intervals in a 80 x 50 meter plot, so it was
a pretty nerve-wracking undertaking. Julie and I got a little tied up flagging
the north edge where only a few plants have survived, but luckily Michael came
to our rescue and put us back on track.
We squished our way out of the field and back to the Hjelm house, where after lunch we worked on our team norm. It was around then that the team realized that the epidemic of googly eyes overtaking Hjelm House has extended to our whiteboard! Stuart and Amy were overheard pondering how to perform fingerprint analysis on the culprit’s work, but since they’re the two main suspects in this open case, was it all a ruse to throw us off?
I spent the rest of the afternoon with Michael as he attempts to impart a year’s worth of knowledge unto me in a scant two weeks. Occasionally it feels as though my cup overfloweth with knowledge, but mostly I’m just looking forward to being as competent as him someday!
The following is our two accounts of first-day field experience, which comprised of orientation to the remnant prairie ecosystem and honing of field skills:
Riley’s Experience
When Erin and I rolled up to the Nessman prairie remnant for directed observations, I immediately felt threatened by the sheer amount of Bromus inermis present at the site. Although it is generally reported to be passive, I did not believe it necessary to disturb the rows of brome grasses that waited on the roadsides. Fortunately, the west ditch had a considerably lower amount of brome, and I felt considerably more comfortable stepping into its diverse collection of cold and warm season grasses, forbs, and legumes. Fortunately, I was not tasked with scouring this site for unknown plants so I was able to create a map of the site in the shelter of the middle of the road. Unfortunately, my partner Erin was not so lucky. Erin spent limited time on the east side of the road (the side with sea of brome), and she was fortunate enough to actually leave the brome sea unscathed. I was pretty impressed by the ninja skills Erin showed to avoid the constant onslaught of Bromus inermis in her personal space, it was cool. However, as Erin moved to the west ditch, there was a change… there was the emergence of an X factor, some may say. When I looked up from my mapmaking, I saw Erin under attack in the west ditch. Not by brome, but by caterpillars. Little known fact about caterpillars: caterpillar is Swahili for “guerilla warfare.” I unfortunately did not know this upon my site visit to Nessman, and I believed for a time that my partner suffered the consequences of many caterpillar attacks. At this point, however, I had known Erin for less that 24 hours and had failed to learn her most important skill: Erin serves as a trusty steed for a wide variety of grounded insects and she can communicate with them via hand signals to say, “Hi my name is Erin and I’ll be your Lyft driver today.” I was so happy to see that this seemingly menacing interaction between caterpillar and partner was actually a mutualistic one… One that I will not forget as I continue my year with the caterpillar whisperer.
Erin’s Experience
Before visiting Nessman I had experienced remnant prairie only a handful of times, and all of those instances occurred earlier that morning. The landscape is gorgeous, diverse, and completely alien to me. I had never been in such a lush grassland before, and after our brief orientation in the morning, I could name maybe one in 100 plants I saw. Before arriving in Minnesota after the long drive from North Carolina, I had only ever seen Echinacea angustifolia on Google Images. Just picking it out from the surrounding prairie plants to estimate the number of flowering heads for our skill-building exercise was difficult. Riley knows his stuff and was an amazing help for any plants I had questions with, and could make a really educated guess even when he was unsure. I couldn’t distract Riley from his tasks forever, though, so I set out on my own to characterize the community for our record. As I carefully stepped over delicate plants and wracked my brain for plant identities and functional groups, I was desperate for something that looked familiar.
When I stumbled upon the first tent caterpillar my mind lit up with recognition before I could even process what I was seeing, or why it reminded me so much of home. I immediately recognized the little fuzzy caterpillar hanging out on a leaf as a friend; it took longer to remember that I spent many springs in my childhood catching the harmless and ubiquitous creatures in jars. Eventually tent caterpillars become far less charismatic tent moths that make unsightly silk nests in trees, but before then they make very good schoolyard pets. I scooped up the caterpillar and examined it for any significant differences from what I remembered in my youth, but it looked just the same as the ones we have back home. The familiar tickly feeling of the caterpillar in my hand was oddly comforting, and I carried it with me for the next few meters of my search before releasing it back to munch on foliage.
As I continued through the west ditch, I was surprised to find many more caterpillars, and not just of the tent variety.
Riley and I discussed the interesting difference in plant assemblage between the two sides of the road; while the east was dominated by invasive species, the west seemed to have greater native diversity of both plants and caterpillars. I look forward to visiting Nessman again in the future and hunting for more caterpillars, or maybe moths and butterflies!
