This article appears in the spring 2025 issue of Horizons, the award-winning quarterly magazine of the Lake County Forest Preserves in northern Illinois.

every acre is ESSENTIAL

Since 1958, the Lake County Forest Preserves has stewarded public funds to protect, manage and restore more than 31,200 acres across 65 sites to provide a healthy, resilient home for 28,850 native plant, animal and insect species as well as miles of trails and countless experiences for all to enjoy.

The Forest Preserves is an essential part of our community. Every acre of restored forest preserve land provides cleaner air, improved water quality, enhanced recreational and health benefits, habitat for pollinators, increased carbon storage and greater flood reduction.

But our restored lands face ongoing threats from invasive species, exotic pests and unpredictable weather. Today’s changing climate requires forward-thinking solutions and innovative, high-quality stewardship of the forest preserves to ensure they remain resilient in an uncertain future.

Gifts from the glaciers: Lake County’s legacy and future of ice

This article appears in the winter 2024 issue of Horizons, the award-winning quarterly magazine of the Lake County Forest Preserves in northern Illinois.

Ice seems temporary. It melts in a glass. It disappears at a sunbeam’s touch. It ebbs with the first relief of spring. But some ice leaves deeper marks than a cold drink.

On the banks of the Fox River in the southwestern corner of Lake County, Illinois, you can see back through time. Not long ago on the 4.5-billion-year arc of Earth’s history, a wall of ice 700–2,000 feet tall covered everything in view today. There was no wide, shallow river. No trees or flowers. Only ice.

Today, 691 acres near the river’s eastern shore make up Grassy Lake Forest Preserve in Lake Barrington. The preserve features 5.6 miles of trails, six scenic overlooks, sedge meadows and mature oak woodlands. Set back less than a quarter mile from the low, forested riverfront is what looks like a medium-sized hill.

A 1.6-mile trail makes a half-spiral as it ascends the hill to an overlook with magnificent views of the Fox River. There, you can rest on a bench, watch the water flow by and ponder this …

You’re sitting on a gift from the glaciers.

Unraveling the science of habitat restoration

This article appears in the summer 2024 issue of Horizons, the award-winning quarterly magazine of the Lake County Forest Preserves in northern Illinois.

From a young age, we’re often taught that planting trees is good for the environment. So, why do we see large areas of trees sometimes removed from your forest preserves, leaving the land temporarily ragged and brown?

The answer is habitat restoration, a sequence of land management activities that improve the health, ecological function and diversity of species at a particular site, according to ecologists at the Lake County Forest Preserves. Sometimes that process involves removing non-native, invasive trees and other species.

During restoration efforts, you may see dramatic visual differences.

What’s wrong with this picture?

Editor’s note: hey readers, Brett Peto here. This month, guest author Pati Vitt, Manager of Restoration Ecology at the Lake County Forest Preserves in northern Illinois, returns with the third part of her series about our research project to restore 180 acres of former farmland within Grant Woods Forest Preserve in Ingleside using a climate-adapted, regionally sourced native seed mix.

This past winter, we planted 800 pounds of native grass seed from southern Illinois and Kentucky in the project area. The goal was (and still is) to help us understand whether we should source native seeds from further south to make our future restoration projects more resilient to climate change.

Unfortunately, as you can probably tell from the photo below, even the best-laid plans can go awry. And so they did, when an unseasonable early drought struck. Pati will pick it up from here.

Growing through change

Editor’s note: hello readers, Brett Peto here. This month, we’ve opened up the floor to guest author Pati Vitt, Manager of Restoration Ecology. She’s here to discuss a recent virtual workshop we held as part of our research project to determine best seed sourcing practices for climate resiliency.

“We know that by 2050, our climate is predicted to be more like Oklahoma,” says Pati. So, we need to understand whether we should source seeds from further south to make our restoration projects more resilient to climate change. To help determine this, we’re procuring 800 pounds of native grass seed from southern Illinois and Kentucky.

This November, we’ll plant those seeds in 180 acres of former agricultural fields at Grant Woods in Ingleside. Then we’ll monitor and compare each species’ growth to seeds sourced from our area. I’ll let Pati pick it up from here.

A new fall fashion

Post by Brett Peto

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.

A group of third-graders from May Whitney Elementary School in Lake Zurich has come to the rescue at Cuba Marsh Forest Preserve. Instead of learning their science standards solely in the classroom, Mrs. Hosteland’s class is addressing an authentic environmental issue through investigation, research and collaborative reports that offer solutions to address the issue of invasive species. These hardworking 8- and 9-year-olds then presented their reports to the District 95 School Board and Lake County Forest Preserve officials. Continue reading →

Wood frogs found!

Discovery is often about being in the right place at the right time. This is exactly what happened recently when a wildlife biologist for the Lake County Forest Preserves was in the right woodland on the right spring day. While monitoring wildlife, a biologist heard sounds from the elusive wood frog (Rana sylvatica). The duck-like breeding calls made by male wood frogs had not been heard in Lake County, Illinois since the late 1980s. This discovery is the first sign of victory following extensive habitat restoration and recent species reintroduction efforts.

Restoring our woodland habitats

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.

MAWO-WHRP-20130124-075

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.
