Plunging into the Wetlands and the Dolomite Pavements on the Prairie

September greeted us with a plunge into the wetlands of Midewin! Toward the beginning of the month, we participated in a volunteer seed collection day at Schoolhouse Wetland. Here, we primarily collected the abundant Dark Green Bulrush (Scirpus atrovirens) and Spotted Joe-Pye Weed (Eutrochium maculatum). During collection, I scouted the area for more species to collect and I found a floating mat of vegetation in the center of the wetland! It was very interesting to see the movement of the mat as I bounced on it!

Aside from the Schoolhouse wetland, we also visited another wet location and were greeted with a field of the Cardinal Flower (Lobelia cardinalis)! I initially spotted the population from the road, which surprised all of us as this beautiful critter was right in front of our eyes the whole time! 

Other than the wetlands, we also spent the majority of our time this month at the dolomite sites. On the dolomite pavements, we pulled the annoying Hairy Cupgrass (Eriochloa villosa) at the beginning of the month. It was a very daunting task to pull every individual of the plant, however, it was satisfying to see the immediate results with the annual grass now gone! Aside from weeding Hairy Cupgrass, we also collected seeds from the minuet Poverty Dropseed (Sporobolus vaginiflorus), Rough Dropseed (Sporobolus compositus), and the fruits of the Prairie Prickly Pear (Opuntia macrorhiza). The prickly pears were my personal favorite as the collection bag smelled incredibly sweet with all the fruits in it! 

Lastly, as the month neared its end, we wrapped it up by cleaning the Dark Green Bulrush (Scirpus atrovirens) in the brush machine. It felt satisfying to not only collect the species but also clean it and prepare it to be used in a seed mix.

Overall, September was eventful on the prairie and the month was over quickly! 

Puddle Clubs and Pollinators of the Prairie

August is here and the pollinators are in a frenzy for forage as fall inches closer!

This month, I took the time to become closely acquainted with the many different flying critters that could bee seen on the prairie. For the most part, the pollinators were not very hard to find as they could typically be found foraging on the pollen/nectar of the prairie wildflowers; however, there were a few exceptions with some of the bees as they would find interest in eating my lunch! 

Aside from foraging on prairie plants or my lunch, the general behavior and nesting habitat of a few of the pollinators were interesting to watch. During Robel Pole protocols with Harsha, Michelle, and the other CLM interns, we were greeted by a group of Pearl Crescents (Phyciodes tharos) and Eastern Tailed-Blues (Cupido comyntas) at a puddle. Until recently, I did not know that this behavior was called Puddle Clubbing. Essentially, puddle clubs are congregations of the same or different species of butterflies (mostly males) that gather around a source of water (sometimes large or measly), which typically contains essential minerals that the butterflies can obtain with their proboscis. The puddles can also serve as an area for males to display and compete for a female if one happens to fly by!

Regarding nesting habitat, the two species of pollinators I observed (a Megachilid sp. and the Honeybee, Apis mellifera) were relatively intriguing, to say the least. The Megachilid (a leafcutter bee) is a resident of the bedrock pavements of the dolomite prairie that we observed while monitoring the Hispid False Mallow (Malvastrum hispidum). In this habitat, there can be little to no soil and the pavements can get relatively hot during the day, so it was impressive to see this species utilizing this area for a home! As interested in bees as I am, I took a closer look at the leaf cutter’s home by moving the rocks at the entrance of the nest to see see how deep it was. Shortly after displacing the rock, Ingrid from POC, Naomi, and I were greeted by a disoriented bee…sorry!

As for the honeybees, we found them within an older building on the prairie while we were seed collecting/scouting. In this case, I was not surprised to stumble upon them here as I have found honeybees in similar structures before, but I was surprised to see exposed comb! It is not ideal for them to utilize the comb for storage or rearing their young, although this comb could serve a hidden purpose not seen by the observer!

With that, August on the prairie was filled with a plethora of pollinators that added to the fun of seed collecting! As fall slowly sets in, I hope to see many more flying/buzzing critters!

Pillars of the Prairie

June is over and the heat of July is finally here!

July at Midewin started with placing transect flags at various locations on the prairie that had their fair share of hazards! I was in primarily mesic habitats with the botany technician, Anna, where we faced thickets of sandbar willows (Salix interior), horsetails (Equisetum sp.), and of course the disgusting Phragmites (Phragmites australis).

Following setup, we began the transects and gathered data for the Floristic Quality Index (FQI). During data collection, it reminded me of a live auction where people would shout their bets at a person, but instead it was the latin/common names of the plants being shouted at the tablet holder!

Within the middle of transect season, a few of us CLMs assisted the previous CLM interns, Harsha and Veronica, in brush cutting the awful Autumn Olive (Elaeagnus umbellatum). As a whole, we managed to cut down a great amount of the shrubs and also break a sweat which attracted the sweat bees!

Aside from transects and brush cutting, the latter half of July was spent collecting and scouting for sedges, rushes, and wetland species. While collecting on the prairie, we found ourselves to be dwarfed in comparison to the pillaring beasts that are in the genus Silphium. The largest plants tended to be seven feet tall (or taller) and had golden inflorescences that would sometimes had a critter in the bloom! All four species of rosinweeds were also relatively abundant in most habitats, but only 3 of the 4 species tended to grow with each other. How rude of the plants to not include the fourth species!

The Silphium, in my opinion, are like the trees of the prairie, as they pillar over most prairie vegetation aside from some Big Bluestem (Andropogon gerardi). Additionally, they also act as pillars within the prairie as they are workhorse species within restorations. Truly, they act like pillars with other species to support a small part of the prairie’s foundation.

I hope to one day view these pillaring plants, with their immense leaves, tickle the bellies of Bison within the tallgrass prairie once again just as Aldo Leopold wished. With that, I hope other people can appreciate the absolute behemoths that are within the genus Silphium as much as I do!

Hopefully August will bring more fun on the prairie when the season changes and more plants bloom! See y’all soon!

Patrollin’ on the Prairie

The month of June kicked off our adventures on the prairie! Initially, we began our field season at Midewin doing meander surveys. A lot of the plants were familiar to me, however, I struggled with a few that I would normally brush off mainly due to them not being very showy (looking at you Carex!). During the meandering, we also had an active competition amongst the volunteers and CLM interns who could ID the last plant in the allotted time. Vlad and I were actively competing to find the coolest plant last, which he found a cool native and I found an Ox-Eye Daisy (Chrysanthemum leucanthemum) an invasive species last. So, for the most part, we tied!

Regarding seed collection, June was spent collecting Atlantic Camas (Camassia scilloides) and multiple Carex species. I feel more confident in my Carex ID and this group no longer frightens me with its extensive amount of terminology! Of all the sedges we observed, I liked Davis’ Sedge (Carex davisii) the most as the perigynia look similar to popcorn kernels.

With seed collection, we were also in a wide variety of habitats like tallgrass prairie and sedge meadows. The sedge meadows were one of my favorites as they had unique tussock sedges that looked like waves of green as the wind blew through them.

Other than camassia and sedges, we also saw other cool critters like insects and many different milkweed species. When I would have down time before work or during lunch, I would take as many photos with my camera as possible. I was definitely more biased to taking pictures of bees and milkweed! 

Speaking of the bees, they were in a rush when it came to foraging on the Leadplant (Amorpha canescens). The species of bees ranged from the small Sweat Bees (Augochlora/Augochloropsis sp.) to many Brown-Belted Bumble Bees (Bombus griseocollis). The flowers of the Leadplant were very fragrant, so I do not blame the bees for being in a hurry to get this limited supply of nectar!

As for the Milkweeds, they were also fragrant and of course had many different insect species on them. Common Milkweed (Asclepias syriaca), for example, smelled strongly of perfume and gained a lot of attraction from the red milkweed beetles (Tetraopes tetrophthalmus). As for the pollinators of common milkweed, flies and bees were a common site as were the milkweed’s pollinia attached to their legs! I also managed to see my first monarch caterpillar (Danaus pleixpplus) of the season hopefully there will be more to come!

Overall, June brought great experiences from meandering in the prairie to learning many of the sedges that occur in Illinois. I can’t wait to get lost in the Silphium forests once they bloom in July, so expect a LOT of Silphium and subsequentially their pollinators in next month’s blog!
