A Very Fermi Prairie Legend

“I had caught prairie fever.” — Dr. Robert Betz

*******

Most people know Fermilab in Batavia, Illinois, as a particle physics and accelerator laboratory. But today, I’m here for the prairie.

Interpretive trail, Fermilab Natural Areas, Batavia, IL.

Fermilab is a protected government area, so a guard checks my driver’s license at the gate, then makes me a guest tag to stick on my coat. He smiles as he hands me a map and waves my car through the checkpoint. I’m off to the interpretive trail…

… to see what delights the December prairie has in store for me this morning.

You might wonder: What is tallgrass prairie doing at a place where phrases like “quantum gravity” and “traversable wormhole” are the norm?

So glad you asked! The prairie was the dream of Dr. Robert “Bob” Betz, a Northeastern Illinois biology professor who was dubbed by the Chicago Tribune as “a pioneer in prairie preservation.” In 1975, Betz heard that Fermilab’s then-director Dr. Robert Wilson was looking for ideas on how to plant its thousands of acres in the Chicago suburbs.

As Betz tells the story in his book, The Prairie of the Illinois Country (published in 2011 after his death), he enlisted the help of The Morton Arboretum’s legendary Ray Schulenberg and Cook County Forest Preserve’s David Blenz to go with him to meet with Dr. Wilson to pitch the prairie project.

Dr. Wilson, Betz said, listened to their ideas. He then proposed the interior of the accelerator ring for planting. “How long would it take to restore such a prairie?” Wilson asked the trio.

Betz admitted it might take five years. Ten. Twenty or more.

Betz writes that Dr. Wilson was quiet for a few seconds, “… and then he turned to us and said, ‘If that’s the case, I guess we should start this afternoon.’ “

What vision these men had! Their dream, coupled with the work of countless volunteers and staff, has birthed this restoration of Illinois’ native landscape across Fermilab’s vast campus today.

I wonder what Dr. Betz would think if he could hike with me this morning, and see the array of tallgrass prairie plants that shimmer under the winter sky…

Interpretive trail, Fermilab Natural Areas, Batavia, IL.

… which changes every few moments, kaleidoscoping from dark clouds to blue sky; contrails to sunshine.

Within view of the interpretative trail looms Wilson Hall, where the nation’s most intelligent scientists mingle and confer.

I think of these scientists as I hike the prairie. The future, meeting the past. I think of Dr. Betz, and his willingness to dream big.

The slogan for Fermilab is this: “We bring the world together to solve the mysteries of matter, energy, space and time.”

The tallgrass prairie is full of mysteries.

It’s a restoration, hearkening to the past, but also the landscape of our future, holding hope for a healthier, more diverse natural world. Because of the work of Dr. Betz and the people who took time to introduce him to prairie in a way that seeded in him a life-long passion for saving and restoring the tallgrass, we can continue to learn about our “landscape of home” here, even as science moves us into the future.

Thanks, Dr. Betz.

You made a difference.

*****

Dr. Robert Betz (1923-2007) caught “prairie fever” after a nature outing with the also-legendary Floyd Swink (Plants of the Chicago Region, first edition 1969). Once Betz was hooked, he became a force of nature in Illinois for prairie conservation and restoration. At the end of his book, The Prairie of the Illinois Country, he writes: “Fortunately, in spite of all the tribulations the Prairie of the Illinois Country has undergone during the past 150 years, its remnants are still with us. But to continue the work that began decades ago to save, protect, restore, and enlarge these remnants, future generations must make a real effort to educate the public about their importance as a natural heritage and ecological treasure…. Hopefully, what this may mean in the future is there would be a plethora of people infected with the author’s ‘prairie fever.‘”

Read more about Dr. Betz in his obituary here, or in this article by former Fermi staff member Ryan Campbell here. A tremendous thanks to all the stewards, staff, and volunteers who keep the Fermilab Natural Areas healthy and thriving. As Dr. Betz wrote, it is an “ecological treasure.”

August Prairie Rain

“…And the soft rain—imagine! imagine! the wild and wondrous journeys still to be ours.” —Mary Oliver

********

It begins before dawn, with a tap-tap-tap on the windows. At last! Rain.

In my backyard, the plants perk up. From the Sun Sugar cherry tomatoes (everyone’s favorite this summer)…

Sun Sugar cherry tomatoes (Tomato Lycopersicon lycopersicum ‘Sun Sugar’), Crosby’s backyard, Glen Ellyn, IL.

…to the mixed kale…

Mixed varieties of kale (Brassica oleracea spp.), Crosby’s backyard, Glen Ellyn, IL.

…to the prairie patch along the backyard fence…

Crosby’s prairie patch, Glen Ellyn, IL.

…it’s as if the earth heaves a sigh of relief. The rain perks me up, too. When was the last time we had a rainy day? I can’t remember.

Water drops bead and splash from Queen of the Prairie, its flowers fading to seed.

Queen of the Prairie (Filipendula rubra), Crosby’s backyard, Glen Ellyn, IL.

The wild asparagus drips, drips, drips.

Wild asparagus (Asparagus officinalis), Crosby’s backyard, Glen Ellyn, IL.

I walk through the grass in the rain and admire the insects braving the wet. A cucumber beetle peers over the top of a spent Royal Catchfly bloom. No cucumbers here, buddy.

The Wild Quinine, Common Mountain Mint, and the last blooms of Butterfly Weed fall together in the best sort of bouquet.

Crosby’s front yard prairie pollinator patch, Glen Ellyn, IL.

Wait—what’s this? Many of my zinnia’s petals have been neatly stripped off, leaving only the centers. I don’t have to look far to find the culprit, just behind the bird feeders, eating Cup Plant seeds.

With two sock thistle feeders and plenty of feeders full of birdseed across the backyard, why eat my wildflower seeds? Ah, well.

Agastache—Hyssop—attracts a different kind of crowd.

Purple Giant Hyssop (Agastache scrophulariifolia) with a Ruby-throated Hummingbird (Archilochus colubris), Crosby’s backyard, Glen Ellyn, IL.

I have a lot of Hyssop this year, gifted to me by generous friends. Last summer, I plopped it into an available space right by the patio without checking to see how tall it would get. Surprise! It towers over my head. Another surprise—sometimes Purple Giant Hyssop is sometimes…white! I won’t win any landscape design points for placing it where I did. And yet, I’m glad it’s where it is. Even in the rain, every little pollinator wants to stop and sip.

The pale pearl buds of blazing star will open any day.

August and anticipation go hand in hand.

Summer is passing. Walking through the yard in the rain, I feel it. Goldenrod shows its metallics. Wildflowers go to seed. Autumn whispers: Not too long, now.

Crosby’s front yard prairie pollinator patch, Glen Ellyn, IL.

My camera lens fogs up again and again. It feels like 100 percent humidity here, but I’m not complaining about the sauna treatment. Because it is raining! Finally.

Flowering Spurge (Euphorbia corollata), Crosby’s front yard, Glen Ellyn, IL.

Welcome back, rain. We missed you.

A Tallgrass Summer Solstice

“Ah summer! What power you have to make us suffer and like it.” — Russell Baker

Happy Summer Solstice! The longest day of the year.

Belmont Prairie, Downers Grove, IL.

And hello, first day of summer, astronomically speaking. We’re on track for one of the hottest days in the Chicago Region this year. Our local WGN weather bureau forecasts a high of 99 degrees and a heat index in the triple digits. Whew! Not a record, but close enough to make a little shade sound good.

Confused Eusarca Moth (Eusarca confusaria), Schulenberg Prairie, Lisle, IL.

We need rain. Despite this, the prairies overflow with flowers.

Summer on the Schulenberg Prairie, Lisle, IL.

As I hike three prairies across two states this week, I chant the wildflower names to refresh my memory. Scurfy pea.

Ants explore goat rue.

There are so many insects associated with these prairie wildflowers! So many insects unfamiliar to me. The more I learn, the more I realize I don’t know.

I pause to admire a dragonfly, performing his balancing act.

Twelve-spotted skimmer dragonfly (Libellula pulchella), Belmont Prairie, Downers Grove, IL.

I love the male twelve-spotted skimmer; one of the easiest dragonflies to remember. It looks just as you’d expect from the name. As I get older, and my recall is less reliable, I’ll take any low hanging fruit I can get.

And don’t get me started on the juvenile birds…

Immature Dickcissel (Spiza americana), Kankakee Sands, Morocco, IN.

…which may look different than their parents.

Dickcissel (Spiza americana), Kankakee Sands, Morocco, IN.

I spot my first buckeye butterfly of the season. Those rich colors!

Buckeye butterfly (Junonia coenia), Kankakee Sands, Morocco, IN.

Then I puzzle over some wildflowers whose name I struggle to remember. I snap a photo with iNaturalist, my phone app.

Wild four o’clocks (Mirabilis nyctaginea), Kankakee Sands, Morocco, IN.

Wild four o’clocks! A non-native in Illinois. And this one?

Clasping (or “common”) Venus’ looking glass (Triodanis perfoliata), Kankakee Sands, Morocco, IN.

I have to look it up with my app, then revisit Gerould Wilhelm and Laura Rericha’s Flora of the Chicago Region when I return home. Venus’ looking glass is a weedy native, but no less pretty for that.

Well, at least I can identify these mammals without an app. No problem with the scientific name, either.

Bison (Bison bison), Kankakee Sands, Morocco, IN.

I love the juxtaposition of the bison against the semis on the highway. A reminder of the power of restoration.

All these wonders under June skies.

Half moon, Schulenberg Prairie, Lisle, IL.

So much waiting to be discovered.

Hello, summer. Welcome back!

Showers of Wildflowers

“All we have to do is turn off our phones, use our senses, and take note of the bewitching beauty that turns up on almost every walk, often in the smallest of things—lichen, moss, insects, raindrops. Anyone can cultivate the capacity to marvel.” — Annabel Streets

*****

Freeze warning. Monday evening, I cover the newly-planted violas in light of the forecast. I bought a few six-packs in a fit of enthusiasm a month ago. They’ve given me joy on my sheltered front porch. Flowers! Color. I’ve brought them in most nights, keeping them from the worst of the bitter temperatures. This weekend, the thermometer hit 80 degrees and I planted out one of the six packs as well as some of my spring garden vegetables. Normally, the sugar snap peas, onion sets and other early veggies would have gone in two weeks ago. But it’s just been so darn dreary and cold.

Rainy day at Nachusa Grasslands, Franklin Grove, IL.

The hot weather this weekend was a nice break from all the rain, rain, rain. Our backyard is wet in the best of times. With the recent rainfall it’s a quagmire. Our knee-high waterproof boots, caked with mud, stand at the ready by the door—necessary for any trip to the compost bin, or to check on the status of new backyard prairie plant shoots. On one trip outside, I pick a bouquet of daffodils and find a sleepy native miner bee snuggled into the flower folds, out of the rain.

My marsh marigolds are relishing the rainfall. When we moved to our tiny suburban yard 24 years ago, one of the first things we did was dig a small pond and plant one marsh marigold on the edge. Yup, just one plant. Two dozen years later, they have spread, a golden necklace that says “spring” to me each season.

Marsh marigolds (Caltha palustris), Crosby’s backyard, Glen Ellyn, IL.

Some folks, seeing how rambunctious these marsh marigolds are, are suspicious. “Are you sure they’re not fig buttercup?” they ask, referring to a pernicious invasive plant, sometimes known as “lesser celandine” or even, “pilewort.” Although some sources say this invasive plant isn’t in my Illinois county, we know better. A wet area in the subdivision across the street has a large spread of lesser celandine (Ficaria verna, or if you prefer the old name, Ranunculus ficaria). It looks a lot like my marsh marigolds from a distance, doesn’t it?

Lesser celandine, or fig buttercup (Ficaria verna), Glen Ellyn, IL.

Take a closer look. One easy way to tell the invasive lesser celandine from the native marsh marigold (Caltha palustris) is to flip the blooms over.

Lesser celandine ( Ficaria verna, left) and marsh marigold (Caltha palustris, right), Glen Ellyn, IL.

See the (somewhat blurry) three green sepals on the back of the lesser celandine on the left (top image)? The back of the marsh marigolds on the right are a solid yellow. There are other differences as well in the leaves and the flowers, but this is a quick and easy method for distinguishing the two. If you want to become better acquainted, grow the marsh marigold in a swampy place in your yard. Their exuberant blooms will cheer you every spring, even in the throes of our exasperating Midwestern swings of weather.

As you hike the prairies and woodlands this week, look for the marsh marigold blooming in the wetter areas. And think of the other wildflowers you’ll see! Hepatica, an early spring woodland favorite, keeps its old leaves through the winter. You can spot their dark maroon and bright green lobed leaves in the lower left-hand side of this image below.

Spring beauties are in bud and in bloom. On a rainy day, they—like many spring woodland wildflowers—will close, or partially close.

Jacob’s ladder is ready to burst into bloom any day now.

More wildflowers are in bloom, and many more are on the way. Who knows what else you might see? Daily, the blooms change as new species open and others decline.

As I hike, a burst of tangerine and black distracts me from the wildflowers.

Eastern comma butterfly (Polygonia comma), The Morton Arboretum, Lisle, IL.

It’s an eastern comma butterfly! It flutters across the woods, then lands in a patch of sunshine. Yes, I know it’s a common Illinois butterfly, but it’s my first butterfly sighting of the year. Delightful if only for this reason.

So many joys! So much to see.

Spring ephemerals, however, are just that….ephemeral. Blink! And they’ll be gone. Why not go for a hike this week and see them while you can? Who knows what marvels you might discover?

The opening quote for today’s blog is from Annabel Streets’ “52 Ways to Walk: The Surprising Science of Walking for Wellness and Joy, One Week at a Time.” One of my favorite passages is this: “Seek out the work of naturalists and nature writers, who can alert us to the miraculous spots of sublimity we might not otherwise notice. Knowledge doesn’t counter mystery; it enlarges it.” Absolutely.
