“There is nothing like looking, if you want to find something. You certainly usually find something, if you look, but it is not always quite the something you were after.”–J.R.R. Tolkien
Spring. At last! It’s come to the prairies and savannas in full flush. Welcome back, prairie trillium.
Hello, Virginia bluebells!
A few days of warmth and sunlight followed by rain and cool nights keep the wildflowers fresh and vibrant. And as always, there is the promise of more to come.
With the first days of May come good news. Our dragonfly data collection efforts at Nachusa Grasslands, restricted in April because of COVID-19, could now—cautiously—begin. Saturday, Jeff and I drove to Franklin Grove, IL, so I could walk several of my regular routes and see what was flying.
The day started out fair and sunny but gradually turned overcast and windy as we traveled. Yet the thought of being back at Nachusa–taking on a task that felt “normal” for spring—was a lift to our spirits. It felt odd to travel an Interstate highway again. Strange to stop and put gas in the car—our Suburu has gotten about eight weeks to the gallon lately. It’s bizarre to see many businesses shuttered; to pass a shopping outlet mall turned COVID testing center, lined with cars. What was so familiar only months ago is now changed.
Arriving at Nachusa, I hop out of the car to maneuver the heavy metal bars of the bison gate open and drive into the bison unit,
Jeff and I scan the prairie ahead. The bison are noticeably absent. How such massive animals can disappear into the prairie is a mystery. I know that this spring, at least nine bison calves have been sighted. I look again. Nada. I remember previous summers and the joy I felt when the mamas and new babies appear.
We continue to look for bison—and dragonflies—as we travel the gravel two-track to one of my route locations. Normally, the first dragonfly monitoring hike of the season is in April, although not much is flying at that time. Common green darners (Anax junius) will have arrived from the south. Freshly-minted dragonflies and damselflies should be emerging from the ponds and streams, ready to participate in the ancient dance of pairing up and creating new life.
Although we’ve driven this two-track many times, it looks different this spring. Nachusa is known for prescribed fire; this is the first time I’ve seen its approximately 3,500 acres untouched by flames at this time of year. If you didn’t know it was May—and ignored the temperature —it could easily be January. But look closer, and you see that underlying carpet of emerald.
Our first stop is a large pond I’ve monitored since 2013. But wait!
Where is it?
What? It’s gone! Oh no…I can’t bear looking.
It was in this pond that I saw my first Northern pintails, migrating through Illinois and stopping for a quick paddle and a bite to eat. It was here I had my one and only face-off with a mama bison; me, carelessly walking my route without paying attention to their movements. This pond is where the great egret would stop to rest on its hunting expeditions. So many memories. What could have caused such a change?
I remember the pond as it was in previous years.
I look again. Wow.
Later, I learn what’s happened. Beavers! They’ve spent the past months re-sculpting the prairie landscape to be more to their liking. Who would have thought? At Nachusa, I usually think about the thousand pound-plus bison and the changes they may make to the places I frequent. Amazing what a few 50-pound beavers can do in a matter of months. Such a big changes from a small animal. I think of Mary Oliver’s poem “Little Owl Who Lives in the Orchard”: “It’s not size, but surge that tells us when we’re in touch with something real…” Although the beavers’ work was slow and gradual; the end result brings about a surge of emotion. The beavers have upended my idea of a place I thought I knew. I feel unsettled.
Onward! Next monitoring route. Once a stream, then re-shaped by beavers several years ago as a pond, now a stream again. It’s fascinating to see the different types of dragonfly and damselfly species change over time with the habitat changes; some dragonflies prefer running water, others choose still water. Jeff sets up his camp chair and pulls out a book while I pick my way alongside the stream, watching for any insect movement.
The skies fill with clouds as the wind picks up, although the temperature remains in the 70s. A great blue heron flies over.
After 30 minutes, it’s clear no Odonates are out and about; at least none I can find. Not surprising at this time of year. I log my times and mark the data sheet with a big fat zero. We pack up, and move to the next route. Around a curve, over a bridge, and across the prairie on the gravel two-track. Still no bison. But—stop the car!— I shout. Jeff quickly pulls over, and we get out and marvel over a carpet of wood betony—Pedicularis canadensis—more than I’ve seen in all my years as a prairie steward.
Wood betony is a hemiparasite which can draw nutrients from other plants, especially prairie grasses. For this reason, it is coveted by prairie stewards who want to open grass-dominate areas for prairie wildflowers. I love this wildflower for its crazy flowers and crinkly leaves.
The bumblebees are working the pinwheeled blooms, sampling one after another.
I read on Illinois Wildflowers website later that long-tongued bees are the primary pollinators, including queen bumblebees and mason bees.
We watch the bees for a while, then clamber back into the car and continue to the next site, a small pool I call the “Power Line Pond.”
Except…not so small anymore.
The beavers strike again!
This pond is flooded almost beyond recognition.
When bison came to Nachusa Grasslands, their hooves changed the shoreline of this watering hole, making it difficult to get close to the water in places. Last year, I re-rerouted my data collection hikes in an ever-widening arc to stay on solid footing. Today, I’m grateful for my knee-high rubber boots. Looks like I’ll be wading.
As I slosh through the water, I see them. Common green darners!
My first dragonfly data for the season. Delighted, I mark my tally sheet. Jeff and I watch them zip across the expanded pond, occasionally stopping to oviposit, then flying to a new spot to start again. Another common green darner appears, flying solo. One of the best moments of dragonfly season is making the first hash mark on your data sheet. Today is that day. The season is off and running. At last.
There are several small ephemeral pools nearby, perhaps bison-made, that sometimes shelter damselflies of various species. Today, all I see are a few water-striders, admiring themselves in the mirror of the sky-reflected water.
One of my all-time favorite novels, Crow Lake, tells the story of three children unexpectedly orphaned in rural Canada. The oldest son, about to leave for college, chooses to invest in his siblings and stay home so they won’t be parceled out to various relatives. By doing so, he comes to terms with his losses, including a promising future derailed. Mary Lawson uses the life of a pond—-in particular, its surface tension—as a way to consider how sudden change may re-route our plans; cause us to reinvent ourselves. The outcomes aren’t always what we’d expected, or even hoped for. It’s how we choose to respond to sudden change that shapes us and our future, she shows through her story.
This trio of common green darners turned out to be all we’d see for the day. A spatter of rain begins, and our hopes of more sightings disappear. We drive out of the bison unit, and head for home. But on the way, we pass Clear Creek, one of my routes I’ve not gotten to today. We swing in and park. The chances are slim to none to see any dragonflies or damselflies, but who can resist one more hike?
As we walk, we glimpse the quick touch-down of a mourning cloak butterfly. This spring, I’ve only seen the cabbage white butterflies and red admirals. Mourning cloak butterflies are unusual in that they often overwinter, then mate in the spring. This one refused to turn around and give us the full glory of its coloration.
But I had seen this species in bright sunlight the previous spring, and marveled.
It is exciting to see the first butterflies of the season. But I want dragonflies. I wade into Clear Creek and scrutinize the shoreline, slowly walking the edges. Later in the season, Clear Creek is populated by ebony jewelwing damselflies and springwater dancer damselflies and shadow darner dragonflies. But today, no damselfly or dragonfly is stirring under the steel gray skies.
I pull a few garlic mustard plants, then wade back to the trail. Jeff has already hiked to the top of Fame Flower Knob, overlooking the creek.
I follow the trail to the top, scrutinizing the new growth as I hike. No dragonflies on the trail…but look!
Sand phlox. An unexpected delight. And over here…pussy toes.
Such unusual flowers. Like a cluster of shaggy Q-tips.
And over here….a small patch of birdfoot violet. So tiny!
I spend some time admiring them up close. Then, I join Jeff.
Together we’re silent, taking in the view. It’s familiar, yet changed by circumstances — the lack of prescribed fire, the work of prairie creatures such as bison and beavers, the temporary lack of stewardship activity over the past weeks during Illinois’ quarantine. Witnessing these changes to a place I care about is part of building a relationship with it.
What other changes will 2020 bring?
There’s no way to know. But I do know this. I’ll be back here, to watch them unfold.
J.R.R. Tolkien is best loved for his “Lord of the Rings” trilogy, and the delightful prequel, The Hobbit. The lines that kick off this post are spoken by the dwarf Thorin to young dwarves in The Hobbit as they look for shelter in a rainstorm on their way to burgle treasure from the fearsome dragon Smaug. Instead of shelter, the dwarves find… well, if you haven’t read the book in a while, this is a great time to revisit it. Read more here.
