That dedication shows up in the numbers. In 2025, our volunteers donated 21,410 hours, valued at $734,149. An average full-time American employee works 2,080 hours per year.

By that measure, volunteers extend our workforce by 10 full-time positions, improving stewardship of 31,900 acres and 66 preserves.

“Our volunteers’ knowledge, enthusiasm and commitment are truly contagious. They’ve helped build a community that feels welcoming, inspiring and deeply connected to the land,” said Community Engagement Specialist Norma Zamudio, who works to support and grow our volunteer program.

Opportunities are open to all, with training provided and no experience necessary. Volunteers are active in habitat restoration, education, seed processing, transcription, gardening, photography and other disciplines.

Mat Sullivan’s volunteer story started with a degraded lake. As an intern with the Lake County Health Department (LCHD) six years ago, he tackled an assignment at Slough Lake within Duck Farm Forest Preserve in Lake Villa.

The 37-acre waterbody was struggling with invasive carp, high phosphorus levels and frequent blue-green algal blooms. Carp are bad news for water quality. Adult carp thrash around during spawning, stirring up sediment on the lakebed. They stir it up even more by feeding on bottom-dwelling insect larvae and crustaceans—aquatic animals with hard shells, such as crayfish.

Sullivan was on the case. During his internship, he helped monitor conditions and remove over 3,000 carp totaling nearly 11,000 pounds from the lake. It was a turning point.

In 2024, LCHD measured a 154% increase in water clarity and an 80% drop in phosphorus levels compared to 2010.

Today, Sullivan works full time at LCHD but felt drawn back to Duck Farm and Slough Lake. He became a restoration volunteer, then a site steward. Stewards lead teams of other restoration volunteers, hosting frequent workdays that last 2–3 hours. They complete certifications in chainsaw safety and herbicide application.

Sullivan has removed invasive plants and helped establish more than 100 native species in Duck Farm’s southern portion. “Pollinators are now showing up,” he said. “I was amazed at how quickly native plants, insects, birds and animals began to rebound. The difference is night and day.”

When Diane Phillips took a career aptitude test in high school, she got two very different results: forest ranger or accountant. For 35 years, Phillips has taught accounting, prepared taxes and worked as a high school administrator. Another decades-long commitment? Volunteering to lead environmental education programs.

In 1991, at a coworker’s urging, Phillips visited Ryerson Conservation Area in Riverwoods. There, she met Mark Hurley, a longtime Forest Preserves environmental educator who retired in summer 2026. He quickly became a mentor.

“I had the teaching skills down, but Mark and other folks helped me grow environmentally,” Phillips said. “I have a banker’s box of index cards at home full of the knowledge I’ve gained from all the educators.”

Environmental education volunteer Diane Phillips has taught countless programs over her 35-year tenure.

She’s taught countless programs: Birdwatching Hot Spots, Sunday Strolls, guided Hike Lake County walks.

Perhaps her favorites to teach have been community campfires held on Friday nights at Greenbelt Forest Preserve in North Chicago. These casual evenings invite families to roast marshmallows, hear stories, make crafts and take a nighttime hike. They reach new audiences.

“Some people have told me, ‘I’ve never had a s’more,’ or ‘I’ve never been to a forest preserve,'” said Phillips. “That always made my heart warm, to know we’ve brought another group into a forest preserve.” Even after 35 years, Phillips still loves volunteering.

“Maybe that career test was right.”

Dave Szaflarski has been visiting Oriole Grove Forest Preserve in Lake Bluff since before it was called Oriole Grove. He knew the 86-acre area along the Skokie River as Lake Bluff Preserve during his childhood.

“My friend lived down the street. We loved exploring the woods, finding old bottles, building forts, watching trains go by,” Szaflarski said.

In adulthood, he volunteered to become Oriole Grove’s site steward. For years, Szaflarski removed invasive buckthorn, dame’s rocket and garlic mustard, applied herbicide and mowed grass trails, often solo.

But not always. A partnership with Lake Forest High School brings environmental studies students to volunteer workdays—in exchange for extra credit.

“If they bring their parents, they can get double credit,” said Szaflarski.

One recent project involved digging up the remnants of a 1920s-era chain-link fence installed when the land was a private estate. Szaflarski appreciates the students’ manual labor while connecting it to deeper lessons. “I tell them, ‘You made the right decision today coming to a workday. Take that positivity forward.'”

Earlier this year, Szaflarski received the Forest Preserves’ Gilman Award to honor his 29 years of service. It celebrates volunteers who demonstrate dedication to an intense project or position.

“It was a surprise. I never thought, ‘Oh, it’s my turn to win,'” he said. “It’s almost like the Academy Awards.”

Most Wednesdays, Barbara Johnson boots up a laptop in the Dunn Museum’s Teich Family Reading Room in Libertyville, selects a handwritten archival document and types it into the 21st century.

Some days, it’s the meeting minutes of a local club describing a potluck. Others, it’s a ledger from the 1840s describing transactions at a general store in Half Day, a former unincorporated town annexed by the village of Vernon Hills in 1993.

The variety of subjects and the challenge of decoding old cursive keep Johnson coming back to help digitize the Museum’s archives.

“It’s like in elementary school when my teachers gave us hieroglyphics and I liked decoding those,” Johnson said. “This is paleography”—the study of historical handwriting systems.

Translation continues to be a specialty. Barbara has written Spanish captions for videos in the Museum’s galleries. Solving historical mysteries is another passion.

Combing through records, Barbara determined the Museum’s namesake Bess Bower Dunn (1877–1959) is buried at the Northshore Garden of Memories in North Chicago. Dunn was Lake County’s first official historian, serving for 60 years.

“It took a while to find that out,” said Johnson. “Once I get an idea in my head, I go after it. I investigate.”

Taking an outstanding photograph requires skill with cameras and an eye for composition.

Photographing the forest preserves requires even more. Awareness of when migratory birds visit Lake County. Of places where spring wildflowers bloom. Of the weather conditions that spark the liveliest fall colors.

Enter our team of six volunteer photographers: Tim Elliott, Liz Rose Fisher, R. Scott McNeill, Bill Oakes, Judith Salstone and Tom Wilson. The group donates thousands of images annually, documenting local landscapes, plants, animals, restoration, education programs and more. Many regularly appear in Horizons.

Scott McNeill offers some advice for aspiring nature photographers. “Keep your head on a swivel. Look up, down and all around,” he said. “Camera memory is cheap. Shoot. Shoot. Shoot.”

Finally, “always photograph for you first. Make an image you like before you worry if others will like or enjoy it.” Connect with us on Flickr to share your photos of the preserves.

Kay Ross and Leroy Howze help feed Lake County one fresh fruit or vegetable at a time.

They tend the Forest Preserves’ 0.08-acre Community Garden Site in Waukegan, a plot of 20 raised beds at Oak Street and McKinley Avenue. We supply the seeds, plants and equipment. Ross and Howze take it from there.

From May through October, the pair grows watermelons, tomatoes, pumpkins, corn, green beans, spinach and carrots. Residents may help themselves to ripe produce.

“We’re giving back to the community, and it feels really good,” said Ross, a program manager for a Chicago insurance company. “It’s fulfilling. It’s also a chance to slow down and reconnect.”

More volunteers—and watchful neighbors to prevent damage by animals and weather—are always welcome.

Volunteers provide serious value to the Forest Preserves, relieving budget pressures and helping us do more. Above are stats from 2025.

These are just a few of our current volunteers’ stories. Everyone is welcome to add their own. Gardeners are needed at the 2.5-acre Independence Grove Native Garden in Libertyville to help plant, prune, mulch, weed and water.

Restoration crews at Nippersink and Kestrel Ridge Forest Preserves in Round Lake, plus Duck Farm and Oriole Grove, could use more hands. (View our current calendar of restoration workdays here.)

Other groups monitor wildlife, process seeds at the Native Seed Nursery in Grayslake, grow flowers and vegetables at Bonner Heritage Farm in Lindenhurst or remove trash and logjams from the Des Plaines River.

Even if a volunteer group is full, we encourage you to apply. Waitlists are available.

Applications aren’t required for restoration workdays—adults and children ages 10 and up can attend with signed waivers.

Give your time and talent at LCFPD.org/volunteer or email volunteer@LCFPD.org.

At first light, a wetland at Rollins Savanna Forest Preserve (Grayslake) stirs to life. Red-winged blackbirds trumpet conk-la-REE-look-at-ME songs from swaying cattails. Wood ducks tip forward to eat plants below the water’s surface, rear ends bobbing in the air.

A great blue heron stands motionless onshore, amber-yellow eyes searching the shallows for tasty fish. The fresh smells of spring drift on a casual breeze as the landscape comes alive. Birdwatching gives you front-row seats to these compelling scenes, especially in Lake County.

Telling the whole story: sharing Native voices

Post by Heather Johnson, Nicole Stocker and Brett Peto

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


Your forest preserves span 31,600 acres, including the traditional homelands of Native peoples. Indigenous cultures existed here starting at least 12,000 years ago, and the community maintains vibrant connections to the land today.

The Forest Preserves and its Dunn Museum in Libertyville partner with American Indian groups to guide us as we share the story of this area.

When you settle into bed for the evening, another world awakens. Flying squirrels launch between trees, bats emerge from roosts and owls begin their silent hunts.

Your forest preserves provide the food, water, shelter and darkness these animals need during their night shifts. Despite their abundance and proximity, our nocturnal neighbors can seem mysterious. The dark obscures their unique activities.

Let’s peek behind the curtain.

Imagine stepping into the woods, leaving behind the noise and stress of daily life. As you pause and breathe, a sense of calm takes over. There’s no rush or destination, only the soothing quiet of the woodland. Welcome to forest bathing, a practice that invites you to reconnect with yourself and nature.

Forest bathing, also called shinrin-yoku or forest therapy, involves immersing yourself in the outdoors—not through exercise or hiking, but by simply being present in the natural world. Its roots stretch back to a 1980s-era effort launched by Japan’s Ministry of Agriculture to help the country’s population reduce stress and improve health.

Forest bathing doesn't require equipment. Just a picnic blanket will do.

Every acre strong: The Community Campaign for Lake County Forest Preserves

Post by Brett Peto

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

Post by Brett Peto

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.

The building looks as if it’s always been there.

As though the floodplain forests of Ryerson Conservation Area in Riverwoods summoned
the smoky green walls, floor-to-ceiling windows and sleek roof.

But the new Ryerson Education Center (REC), opened spring 2024, is the culmination of three years of planning and an ambitious goal. Create a net-zero energy building that produces as much power as it consumes each year.

“We want to raise the bar and set the example for green buildings and environmental sustainability,” said Alex Ty Kovach, executive director of the Forest Preserves. “Our goal is that this new building will become a viable model of long-lasting, energy-efficient design.”

Unraveling the science of habitat restoration

Guest post by Kim Mikus

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.
