The weather has varied a lot so far this spring. Minor snow squalls and hailstorms trade off with wonderfully warm, sunny days, which seem to call out, encouraging us to find the signs of spring. When the season brings all the beauty and promise of plants and flowers emerging from the winter, I feel as if I am seeing friends old and new once again. It’s rather comforting to know that regardless of what occurs in human society, spring carries on in the Lake County Forest Preserves in northern Illinois.
Many of the floral signs of spring are ephemeral, created by healthy populations of plant species that only emerge above ground for six to eight weeks—between the start of the spring warm-up and the closure of the canopy, when the trees grow a full set of leaves. Their live-fast lifestyle is an evolved response to their shade intolerance. Ephemerals need to finish flowering and fruiting while they have enough sunlight, and also put something away for a rainy day. They stash the sugar they make during photosynthesis in underground storage organs such as corms, bulbs, and rhizomes. The starchy carbon will see them through the winter into the next spring.
Some residents of our woodlands and prairies announce the arrival of spring in understated ways that require careful attention. The early-flowering harbinger of spring (Erigenia bulbosa), and later bloodroot (Sanguinaria canadensis), are two examples. Other signs of spring are exuberant and showy, such as the carpets of marsh marigold (Caltha palustris) at Ryerson Conservation Area in Riverwoods. And of course, no spring display is quite so welcome as large-flowered trillium (Trillium grandiflorum) in full bloom. (This sight is only possible when the white-tailed deer (Odocoileus virginianus) population is stable; otherwise these beautiful plants are eaten out of existence.)
Not all spring wildflowers are showy, though, and not all of them are ephemeral. Arriving later in the season, Jack-in-the-pulpit (Arisaema triphyllum) is one of the most common spring wildflowers in our woodlands. It’s usually entirely green in Lake County. Rarely, some maroon stripes may also be seen on the inflorescence, the reproductive portion of the plant.
The sky to the west was robin’s egg blue, a clearing in the day’s dose of clouds. They had just sneezed a handful of snow, already melting. I drove with the radio off. I didn’t know whether to wear my regular hiking boots or a pair of Wellington boots I’d packed at the last moment. The trail could be soggy, or maybe not. I was on my way to Sun Lake in Lake Villa, part of the Lake County Forest Preserves in northern Illinois.
For this month, I decided to revisit the idea behind my February 2019 post, when I explored a new-to-me preserve and wrote up my observations as a virtual tour. Readers seemed to enjoy it, and I enjoyed circling another name on the map I keep at my desk. So, here I was, about a year later, ready to chronicle another tour. Find a comfy chair and a warm mug. Here’s a snapshot of Sun Lake as I saw it.
I keep thinking about angles. Not the kind you measure with a protractor, but those you measure with your mind. The angle of a story, a conversation, or a project. Photography, of course, uses physical angles—where’s the camera pointed? is the sun directly overhead or is it the sweet time of golden hour?—but the best photos make you want to see even more. They make you want to break open the frame and soak in every bit of the Lake County Forest Preserves in northern Illinois.
Since it’s nearly the end of 2019, I thought I’d turn 180 degrees and peruse the photos uploaded to our group Flickr pool since January 1. Suffice to say: we’re spoiled. Spoiled with the beauty of Lake County’s flora, fauna, and natural areas, and the talent of the photographers who capture it for everyone to see. Trees and shrubs in their bright fall wardrobes on either side of a trail draining into a vanishing point. A sandhill crane (Grus canadensis) with both wings up like a paper airplane as it dashes to take off. A whirlpool of stars spun around a rich blue sky over a tranquil wetland.
I’ve gathered these moments plus seven more below, but that’s only a small taste. I encourage you to browse the rest of the visual buffet as we make the turn out of the 2010s into the 2020s. And, hey! You might become inclined to upload that shot living on your phone, camera, or computer.
Everyone has one! At least, anyone who regularly hikes in the Lake County Forest Preserves in northern Illinois has one: a favorite trail. It might be the trail near your home or the one that reminds you of a secret only-I-know-about-this spot growing up. Maybe it holds a special memory. Whatever the reason, something about it always sparks joy in your heart.
Fall is the time of harvest here in the Midwest. Golden stacks of hay bales, farmer’s markets teeming with end-of-season produce, and above all, apples. But step away from the orchard and into an oak woodland and you’ll find a different kind of autumn apple: an oak apple gall. What looks like a small, lime-green, spotted apple dangling from an oak leaf is not a fruit at all, but rather a secret abode for a tiny wasp.
There are more than 50 species of oak apple gall wasps in North America. Each one creates a unique fruit-like structure that protects and feeds its eggs and larvae as they develop. Lately, I’ve been finding many dried, spent brown husks created by the larger empty oak apple wasp (Amphibolips quercusinanis) around the Lake County Forest Preserves in northern Illinois.
The air was warm, the sunshine spread everywhere. Spiderwort blooms were freshly open, a waist-high meadow of bluish-purple fireworks. We found the steel T-post marking the start of the day’s first transect and the red flag for the first plot.
Then we gathered our tools. A one-meter-square collapsible wooden quadrat, retractable tape measure, clipboard, data sheets, and each other’s knowledge of plants.
Well, my own knowledge, not so much. I was there to take photos and observe the three experts onsite: Pati Vitt, Manager of Ecological Restoration; Ken Klick, Restoration Ecologist II; and Pete Jackson, who authored a 2009 study on this preserve’s plant communities that served as his thesis for a master’s degree program. In my head, I called them the Plant Team.
In mid-January, it felt like a good time to circle another name: Heron Creek in Lake Zurich, Illinois. It surprised me that I’d never walked its trails. A 242-acre preserve home to rolling woodlands, fields, the Indian Creek basin, and more than 116 species of birds, Heron Creek is closer to our General Offices than several sites I had been to. It was even roughly on my route to and from work. So toward the end of January, I took myself, some winter weather gear, and a few cameras there to explore.
Time can never be stopped, sped up, or slowed down. It started long before now and will continue far after. But with photographs, we can pause time, pin it in front of us, and study reality. It’s like kneeling at a riverbank and scooping a handful of water. The current stops in your palm, but just a foot beneath it carries on. Photos take time to make a moment.
With nearly 31,000 acres to explore, many moments are possible in the Lake County Forest Preserves in northern Illinois. An eastern bluebird (Sialia sialis) landing with one foot, wings at sharp angles. A cluster of milkweed seeds hanging on to their pod by threads of floss. Sunflowers and sunbeams, two shades of honey mixing in the air. I’ve collected these special moments and more in a gallery below.
All photos featured were taken by the truly skillful photographers in our group Flickr pool. Each of these images, these presses of the pause button and scoops out of the river, were captured in 2018. Our sincere thanks go to every photographer who shares their time and talent documenting the flora, fauna, and natural areas of Lake County.
Fall is my favorite season. I know it’s here on the first day I walk outside into the sort of air so crisp it makes your nose run instantly, somehow in a good way. Sunset shifts sooner. You opt for a sweater instead of a t-shirt and everything pumpkin-flavored becomes tastier than you remember. Best of all, the crowns of oaks, hickories, maples, and more across the Lake County Forest Preserves in Illinois change into their vibrant fall fashions.
