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.
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.
As summer winds down, a telltale hum that signals the changing seasons begins to ramp up in the fields and forests. These trills and chirps are the mating calls of tree crickets (Oecanthinae)—a group of fascinating insects that are often heard but seldom known or seen. Their small size and mint green color helps camouflage them amidst the verdant grasses, shrubs and trees of late summer.
The wooded habitats along the Des Plaines River in southern Lake County, Illinois are changing. Last winter, the Lake County Forest Preserves completed 194 acres of canopy and understory thinning in woodland communities at MacArthur Woods and Grainger Woods Forest Preserves. This winter, woodland habitat restoration has begun at Captain Daniel Wright Woods and Ryerson Conservation Area, in addition to continuing at MacArthur Woods.
The restoration and species monitoring that will continue within these natural areas for the next 20 years will help ensure the sustainability of oak woodlands and the wildlife they support for many generations to come.
Winter visitors to these preserves, or vehicular passersby, will notice the use of heavy equipment, burning piles of brush, and an already visible difference in the openness of the woodland landscape. A number of canopy trees are being removed to increase the amount of sunlight reaching the ground. Visit these areas again when the leaves return, and early results of the Woodland Habitat Restoration Project will be obvious. Continue reading →
This past weekend I had the pleasure of hearing Kenn Kaufman, a naturalist and bird expert, speak at the Smith Nature Symposium. He is somewhat of a “rock star” in the birding world. His novel, Kingbird Highway, chronicles a personal adventure hitchhiking around the country at the age of 16 on a quest to find birds—a story that has reached the status of folklore. Many years later, and surely a much longer “life list,” his keynote address at Ryerson Conservation Area focused on warbler migration: the phenomenon of these teeny tiny birds in every hue of the rainbow that travel thousands of miles across entire continents each spring and fall. He presented complicated doppler maps and in-depth scientific research on these migratory dynamos, but by the end of the discussion the focus had shifted to something more simple: the children from his young birders club.
Late that evening, as I settled down with one of his many guide books, Field Guide to Advanced Birding, I was struck by this same theme of simplicity. Kaufman urges folks to slow down and focus not on looking for the birds, but instead to spend time looking at the birds. He stresses getting to know the common birds of an area very well. By doing so, we are well on our way to knowing when a rare bird may enter the scene. This concept brought to mind one of the best places to take a long look at one common bird of Lake County, Illinois: a great blue heron rookery.
With the recent snow and cold weather, last summer’s dry heat seems like a distant memory. Yet, it was only this past week that the National Weather Service officially changed its “moderate drought” designation to “abnormally dry” for most of Lake County, Illinois (although, a small northwest portion of the county is still considered to be in a “moderate drought”). While every drop of rain and flake of snow is helping to slowly ease our way out of the past eight months of drought, the damage already done will decide the sweetness of this spring.
Each spring for the past three decades, the naturalists at Ryerson Conservation Area have tapped sugar maple trees to harvest the sap and turn it into pure maple syrup.
Even though Illinois recently received a break from this summer’s heat and drought, the precipitation deficit that remains statewide has kicked off autumn with atypical natural events. Thus far, the year 2012 has been the fourth driest on Illinois record. However, it has been raining acorns and fall colors have been peeking through the greenery since late August—three weeks earlier than usual. This fast-forward to fall is a tree’s way of protecting itself when water is in short supply. The vibrant color displays of autumn, which seem so lively, are actually a sign that a tree is entering dormancy.
These flashes of fall colors are a result of changes in pigments. The dominant green pigment in leaves is chlorophyll. The leaves in a tree are like little factories, mixing together a recipe of specific ingredients (sunlight, carbon dioxide and water) to make food for the tree’s growth. Chlorophyll acts as the “chef” in this process, called photosynthesis; its presence is necessary in bringing everything together.
Typically, autumn’s cool nights and shortening days trigger photosynthesis to slow down. The scarcity of one key ingredient, water, is triggering this earlier-than-average dormancy. As the work of the leaves comes to an end for the year, chlorophyll breaks down and reveals yellow and orange pigments that have hidden behind its green cloak all summer. Leaves that contain the pigments xanthophyll and carotene—as do hickories, cottonwoods, elms and some maples—will change to vivid shades of yellow and orange as the green fades. Continue reading →
