Time & talent: the value of volunteers

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.

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.

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.

Monitoring for the future

Post by Jen Berlinghof

It was a bone-chilling winter’s day at Captain Daniel Wright Woods in Mettawa—part of the Lake County Forest Preserves in northern Illinois—when a group of five gathered to monitor for the future. Our crew consisted of Restoration Ecologists Ken Klick and Dan Sandacz, Environmental Educator Eileen Davis, Environmental Communications Specialist Brett Peto and myself.

It’s all hands on deck for an ambitious new tree monitoring program with the lofty goal of sampling every woodland, upland forest and flatwoods habitat within the Forest Preserves every 10–15 years. Ken and Dan are spearheading this project.

In the field, the pair are like bookends. Ken has served 25 years at the agency, while Dan is fresh to the Forest Preserves, starting his tenure this past fall. The two have opted to take a collaborative approach, inviting volunteers from our Natural Resources and Education Departments to help with this significant undertaking.

Planting for pollinators

Guest post by Eileen Davis

It’s a sunny July afternoon at a Lake County Forest Preserve in northern Illinois. The humidity is low and the breeze is just right. I’m poised over a patch of wild bergamot (Monarda fistulosa), furiously clicking away with my camera, hoping to get at least one image that will be clear enough for me to identify the native bumble bee feeding on the flower. If there’s a better way to spend a Saturday afternoon, I haven’t found it.

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.

Become a community scientist

Post by Jen Berlinghof

While the past year and a half has kept many of us mostly at home, nature in our backyards and beyond has provided a balm for these trying times. General use of the Lake County Forest Preserves in northern Illinois is trending 30% higher in 2021 than a typical pre-pandemic year. And in 2020, there was an astounding 70% surge in visitation. The number of folks delving into home gardening and backyard birding has skyrocketed as well, making headlines by leaving store shelves bare of birdseed and bird feeders. The COVID-19 pandemic has amplified our desire to connect to nature closer to home, and it has created space and time for local, daily observations. All of this translates to an environment ripe for community science, also called citizen science.

A native garden to call your own

Guest post by Eileen Davis

What is your earliest gardening memory? Was it planting a seed in a paper cup at school, and watching it sprout and grow on the classroom windowsill? Perhaps you gathered dandelion flowers and presented your mom with a beautiful, yellow bouquet. Or did you rake up a giant pile of leaves to jump in on a crisp fall day? You might even have visited the native garden at Independence Grove in Libertyville, part of the Lake County Forest Preserves in northern Illinois.

My earliest gardening memory is helping my aunt and uncle in their garden. I was only about four or five years old, but I clearly remember the prickly feeling of the cucumber vines scratching my forearm as I helped pull weeds. No matter the memory, we are all doing the same thing—tending to our little piece of the Earth. It’s something humans have done for thousands and thousands of years. We are and always have been dependent on our environment for survival.
