Fall Comes to the Prairie

“Delicious autumn! My very soul is wedded to it, and if I were a bird I would fly about the earth seeking the successive autumns.”–George Eliot

******

The Canada geese are quarreling. I watch them elbow each other out of the way in mid-flight; honking and diving. Maybe they are arguing the mysteries of matter, or particle physics? After all, they’re at Fermilab, a government facility for particle physics and an accelerator laboratory just down the road from my house. The facility grounds are a  mosaic of beautiful natural areas, including prairies and wetlands. fermilabWMwilsonhall10118.jpg

The bison grazing nearby on the grounds seem more placid than the geese, untroubled by neutrino experiments or accelerator science.

You can almost imagine their thoughts. Hey geese! Keep it down. What’s all the fuss about? At any rate, I’m not here to bison watch, and I have little patience for quarrels today, geese or otherwise. My destination is a prairie trail.pathatfermiprairie10118WM.jpg

Approximately one thousand acres of Fermilab Natural Areas, surrounding the government world of equations and physics, promises endless adventures. And today, there’s not a soul on the prairie path. Although it’s obvious I’m not alone.

Overhead, green darner dragonflies hover high above the tallgrass. Are they migrating south? Or waiting out their lives here? Hard to tell. But this late in the season I suspect they’re on their way to warmer places. Lately, a black saddlebags dragonfly, also migratory, has hung around my backyard, slow and torpid in the colder weather. Imagine those wings taking it thousands of miles! Close up the wing veination reminds me of ferns.

I continue hiking, stepping in coyote scat on the trail. Oops! Better watch where I’m going. An insect sings a single note, as if struck from a tuning fork. Everywhere, there are tiny crackling sounds. Mice eating seeds? Birds rustling in the grasses? Leaves drying in the  sun? Part of the prairie’s mystery.

The dogbane or Indian hemp, as it is sometimes called, is gone to seed in places. Its soft silks contrast with the crisp, browning leaves of neighboring prairie plants and their tinker-toy stems.dogbaneindianhemp10118WM.jpg

Wildflowers are mostly of the goldenrod and aster variety, with a few exceptions. Some mountain mint. A last pale prairie Indian plantain bloom or two.

The stiff gentians, those party girls of the fall, are out in full regalia. Looks like a weevil might be crashing the fun.

stiffgentian10118WM.jpg

So many gentians! They are abundant here, like amethysts scattered deep in the tallgrass. Nearby, goldenrod galls create their own sort of green “flowers” everywhere I look.  Sometimes called “bunch galls” or “rosette galls,” they are formed by insects. Check out more about goldenrod galls here.

You could enjoyably spend several hours searching for the different goldenrod galls (ellipse, ball, rosette, small bunch…), and reading up on their buggy creators. See one bunch gall, and suddenly the others come into focus.

The rosin weed blooms are past, but their seedheads look like floral bouquets, don’t they? As pretty in seed as in flower.

rosinweedFermi10118WM.jpg

Everywhere there are riots of asters; including many species of white aster that I struggle to name. More easily ID’d is the ubiquitous New England aster, poised on the prairie like a satellite dish with fringe.

newenglandaster10118WM.jpg

It’s not all prettiness and pleasantry.  The tall coreopsis is in seed, towering over my head, and  I can’t resist pulling down a seedhead and digging into it with my fingernail even though I know I’ll be repelled. And I am. It oozes a smelly, oily substance—and I quickly let the stem spring back. Of all the seeds we collect each fall on the prairie, this is my least favorite. So pretty in bloom! So stinky in your hands.tallcoreposisWMFermi10118.jpg

Rot and decay, the calling cards of October, are juxtaposed with these last flushes of bloom and seed. A giant puffball lies shattered and corrupt, broken up by small mammals and now fodder for insect life.

giantpuffballfermi10118WM.jpg

And in proportion to the slow decline of plants, the insects seemingly flourish. You don’t notice them so much at first, except for the mosquitoes who won’t be ignored. But take a moment and look—really look—at the grasses and flowers, and all at once, you realize they are teeming with insect life. So much diversity!

Decay can be beautiful. The turn of the prairie dock leaf…

The compass plant seedheads, dry and full of promise for new life.

Wild quinine, its silvered seeds perhaps more lovely than the flowers themselves were.wildquinineWMFermi10118.jpg

In autumn, the balance of light to dark shifts, tipping ever-so-slowly toward darkness as the days go by. Change is in the air. Bloom to seed. Flourishing to decline. All this change is in evidence here this morning.

So much to see in one short morning hike here! Who knows what other adventures will unfold this October on the prairie?

The opening quote about autumn is from Mary Ann Evans (1819-1880), a Victorian-era English novelist and poet who wrote under the pen name George Eliot. She chose a man’s name to escape being thought of as a romance writer. Among her books are Middlemarch, The Mill on the Floss, and Silas Marner.

A Vision for Prairie

“What are we made of? How did the universe begin? What secrets do the smallest, most elemental particles of matter hold, and how can they help us understand the intricacies of space and time?”–Fermilab

I’m pondering some the above questions as I hike Fermilab’s prairies and natural areas. It’s 95 degrees with a heat index of about 110. Outside is not where the rational part of me wants to be. But today, I have a chance to explore some of the iconic prairie plantings at Fermilab. I don’t want to miss the opportunity.

Fermilab is a 6,800 acre particle physics laboratory about an hour west of Chicago, established in 1967.  Their stated vision is to “solve the mysteries of matter, energy, space and time for the benefit of all.” I admire Fermilab’s drive to know. But as someone who barely passed physics in high school and dropped out of calculus, I’m not here for the  particle accelerators and neutrino science. I’m here for their prairie.

And what beautiful sweeps of tallgrass are all around me.

The compass plant flowers (above) wave over my head, their periscope-like blooms splashing the prairie with yellow. Waist-high Culver’s root (below) is in the early stages of bloom. Its white candles are luminescent in the tallgrass.

To restore prairie in this place is an act of creativity and the imagination, as well as an act of science. Biochemist Dr. Robert Betz had a vision for the vast acreage that surrounds Fermilab’s accelerator ring and the grounds around the various research labs and buildings. Today, the results of that vision and the tireless work of volunteers, with leadership by ecologist Ryan Campbell, are almost 1,000 acres of planted tallgrass prairie. The prairie, along with other natural areas, encompasses “high-quality aquatic habitats, rare orchids, and even nesting Osprey”.

All around me is evidence of a successful outcome. Butterflies are puddling along the two-track, including this pretty little tailed-blue. They’re attracted to the salts and minerals in the dirt.

Impressive oak savannas edge the prairies. Their cool shade is a welcome contrast to the blazing heat. The wetlands along the two-track gravel road are home to myriad dragonflies, water birds, and other aquatic life. The wetlands are lush. Brimming with water after the rain of previous weeks.

Speaking of dragonflies! They are out in full force on my hike, despite the fierce heat. As I walk,  at least half a dozen Halloween pennant dragonflies are stationed in the tallgrass at regular intervals. Although much about dragonfly body temperature regulation is unknown, we do know that when it is hot they use strategies to lower their body heat. This one has its abdomen pointed downward to cool off.

fermihalloweenpennant62918wm.jpg

Other times you’ll see dragonflies doing handstands across the prairie in hot weather, a thermoregulatory practice called obelisking that helps deflect heat.

I need some strategies of my  own to get out of the hot, sticky weather—strategies that don’t involve standing on my head or other gymnastics. Time to find my air-conditioned car. Whew!

Each prairie has its own delights. On the Schulenberg Prairie at The Morton Arboretum where I’m a steward supervisor, bunchflower is in eye-popping bloom this week. BunchflowerSPMA7218CROSBYwm.jpg

The lilies make me want to sit for an hour and just look. (Mosquitoes quickly put an end to that notion.)

SchulenbergPrairie7218lilymichiganwmjpg.jpg

Nachusa Grasslands, where I’m also a steward,  is carpeted with wildflowers of all descriptions this month. Like an impressionist painting, isn’t it?

These two prairies both have some beautiful butterflies. Like this black swallowtail at the Schulenberg Prairie, which flew erratically across the flowers and led me on a merry chase for a closer view.

Sometimes, as I’m busy tending to my responsibilities on these two sites, it’s easy to forget how many other astonishing prairies there are all around me.  The last time I hiked Fermilab this year, it had just been burned. Look at it now!

There is joy in the familiar. But delight in new discoveries.  Although I’ve been coming to Fermilab Natural Areas off and on now for years, today’s short road trip is a mental post-it note reminder to myself to not get in a “prairie rut.” Visit new prairies.  Discover the delights of seeing prairie restoration in all its variations. Expand my perspective. Learn from what other stewards are doing. Hit the road and see what new tallgrass adventures await.

Where will your next prairie adventure take you?

Grateful thanks to art gallery curator Georgia Schwender who (despite ferocious heat) offered me a tour of some of Fermilab’s natural areas. Check out Fermilab’s Art Gallery on the second floor of the Wilson Building in all seasons. Look for Fermilab’s “Seeing the Prairie” exhibit July 27-September 28, 2018.
