The Perils of Prairie ID

“I’d like to be sure of something—even if it is just going to sleep.” — Theodore Roethke

What’s in a name? Lately, I’ve been stressing the importance of learning scientific names  for plants, animals, and insects in my prairie classes and with my prairie workday volunteers. In doing so, I’ve found renewed appreciation for the simple ones.

The best: Bison bison.

Easy, right? If only the rest of them were!

I mostly love the scientific names. They keep everyone on the same page about what is being discussed regardless of region, and they often tell me something about a prairie plant, animal, or insect. Like the pale purple coneflower, Echinacea pallida, whose genus Echinacea means—from the ancient Greek—“hedgehog.”

 

Quite the resemblance!

But as steward and prairie instructor, staying a step ahead of my students and smart workday volunteers is tough. I was trained in art and journalism, not botany. Species identification makes me painfully aware of my botanical inadequacies.

At Nachusa Grasslands, with more than 700 plant species, the likelihood of stumbling over something I don’t know is certain. On the Schulenberg Prairie, we have 500 kinds of plants on 100 acres. And that’s just the plants! There are myriad opportunities to dub plants, birds, insects, and other members of the prairie community with the wrong name.

I’m also a dragonfly monitor at both prairies, and I like to think I know most of what’s flying on my sites. Ha! As I waded a stream at the Schulenberg Prairie last week, these two elegant damselflies, finding romance alongside Willoway Brook, were a cinch to name.

Ebony jewelwings! No trouble there. I dutifully noted them on my data sheet. But  I also found this pretty little damselfly.

Hmmmm. I was certain it was something I hadn’t seen before. My field guides were in the car and I was thigh-deep in the stream.  I scribbled some guesses on my clipboard data sheet. “Rainbow bluet?” “Variable dancer?” Later, flipping through the field guide, it turned out this was one of the most common damselflies of all; an eastern forktail that had a different variation of coloring—nothing earth shattering, just not a variation I’d  previously seen.

Well then. Another reason to use pencil on the data sheet.

Makes me grateful for the simple damselflies, like the American rubyspot—nothing else in my region looks like them. And isn’t it nice when the common name speaks to the actual appearance of the species? Ruby…

Check. Spot?

Double check.

One of the joys of looking for dragonflies is stumbling across another insect, animal, or plant species I wasn’t expecting to see. While looking for midland clubtail dragonflies at Nachusa Grasslands, I found this pretty little plant.

“Sedge” was not on the tip of my tongue. But a sedge it was, and after asking a friend who is a whiz at plant ID for input; poring over my new copy of Flora of the Chicago Region;  and crowdsourcing a confirmation from the good folks at Facebook’s “Illinois Botany” page, it was determined to be narrow-leaved cottongrass. Yes, cottongrass! You heard that name right.  And it’s a sedge, not a grass, despite the name.

And people wonder why identifying plants is confusing!

Try explaining blue-eyed grass. Neither blue-eyed. Nor a grass.

Or late horse gentian, which is not—you guessed it —a gentian nor anything remotely equestrian. Maybe that’s why I prefer the common name, “wild coffee.”

My most recent ID discussion was over this pretty little wildflower below. Native? Or non-native? Cinquefoil for sure. But which one?

And what species of bee is nectaring here? At Nachusa Grasslands, we have at least 75 different bee species. Good luck to me keying that bee out. I had more success with the cinquefoil (see ID at the end).

At some point, taxonomists begin to tinker and soon, you discover the names you put so much sweat equity into learning have been changed. And that’s more of a problem if you don’t get the name right in the first place.

This little grass that I thought was white-haired panic grass…

…turned out to be the woolly panic grass. So my initial ID was incorrect. Then, I learned the panic grasses—a favorite!—have been reclassified and renamed. The new scientific name Dichanthelium acuminatum  has the common name: “tapered rosette grass.” Definitely does not have the charm of “woolly panic grass,” which conjures up delightful images of sheep bouncing around a field. “Tapered rosette” seems quite buttoned up.  

Darn taxonomists.

Meanwhile, I console myself by noting my ID percentages are still better than the Chicago Cubs’ win-loss percentage this season (.500 at this writing). I continue to work on identification in consultation with smarter friends, pore over excellent books, and plug along the best I can. Knowing that my skills will improve. Prodding myself to be willing to be wrong in pursuit of learning new things. Reminding myself how much I’ve learned since I saw my first tallgrass prairie almost 20 years ago.

Isn’t that the way of the natural world? The more you know, the more you discover you don’t know. The more you see, the more you realize you aren’t seeing.

And yet. I might get all the scientific names correct—learn grasses and sedges; figure out the different colors of the eastern forktail at its various life stages—and still not “know” a species. “Knowing” comes through building a relationship with a place, and the community that inhabits it.  Seeing it in all weather, at many times of the day, in all four seasons. Getting hot, sweaty, dirty, buggy, and wet. Watching the damselflies form their heart-shaped wheel. Listening to the dickcissel sing. Touching the prickly center of a pale purple coneflower. Then, the identifications–those crazy names– become a part of my story and the story of that place.

And if I get a plant name wrong or forget which dragonfly is which?

Tomorrow’s another day.

The opening quote in this post is from Straw for the Fire, an edited collection from the poet Theodore Roethke’s (1908-1963) notebooks by another amazing poet, David Wagoner (read Wagoner’s poem Lost.) Roethke’s father ran a 25-acre greenhouse in Saginaw, MI, where he grew up. A difficult childhood (his father died when he was 14; an uncle committed suicide); a battle with manic depression, numerous breakdowns, his mysticism, and a feeling of alienation were foils for some tremendous poetry about the natural world and the inner self. Roethke won the Pulitzer Prize for Poetry (1954) and the National Book Award for Poetry twice (1959 and 1965, posthumously). He was also a revered professor at Michigan State University.
