Your Tax Dollars at Work in Nature

This winter the Forest Preserve District will start work to restore 31 acres of woodland habitat at Hickory Grove, 87 at Egermann Woods, 550 at Herrick Lake, and 72 at Waterfall Glen, all designed to further the agency’s mission to preserve the flora, fauna, and scenic beauty of DuPage natural areas.

Invasive and exotic species are keeping sun and water from reaching the grasses, wildflowers, and oak and hickory seedlings that grow at these sites. As a result, the variety of plants and animals that live there is declining.

Crews will cut invasive trees and shrubs and conduct beneficial prescription burns. The mature hickories and majestic oaks will remain untouched, promoting further germination of young seedlings.

Because these projects require construction crews with heavy equipment, for visitors’ safety the restoration areas, including some trails, may periodically close during winter. For certain activities, only Forest Preserve District employees and contractors will be allowed in the area. The District will post signs to let visitors know when this occurs and expects the bulk of all four projects to be completed by December 2024.


More Good News for Endangered Dragonflies

For six years the Forest Preserve District has been raising federally endangered Hine’s emerald dragonflies at the Urban Stream Research Center at Blackwell. The center’s efforts focus on DuPage, but its ecologists also collaborate with outside agencies to boost populations of these nationally rare insects.

Recently, the Urban Stream Research Center received 101 larvae from the U.S. Fish and Wildlife Service’s Genoa National Fish Hatchery in Wisconsin. The dragonflies started out at the hatchery but needed a place to overwinter. These insects will join the 30 larvae and 1,000 eggs already housed at the center. The District also assisted the transfer of 100 eggs from the center to the Jake Wolf Memorial Fish Hatchery in Topeka, Illinois, which recently joined the partnership to raise Hine’s emeralds.

In other news, the University of South Dakota, another partner organization, received a Recovery Challenge Grant from the U.S. Fish and Wildlife Service, highlighting the importance of boosting Hine’s emerald dragonfly numbers by providing much-needed resources to the rearing efforts at the Urban Stream Research Center.

Let's "Rays" a Cleaner Tomorrow

For more than 100 years the Forest Preserve District has restored prairies, woodlands, and wetlands to create sustainable landscapes in DuPage.

Today, we’re adopting new operational strategies to further support the environment.

To start, we’ve created a fleet of vehicles and equipment (including tractors and lawn mowers) that use alternative fuels or hybrid technology. This has lowered fuel expenditures, reduced tailpipe emissions, and lengthened the lifespan of our equipment. But that’s not enough.

With a pledge from gracious donors, we’re also installing a solar array on the fleet management building at Blackwell Forest Preserve. The 330-kilowatt array will be capable of producing 384 megawatt hours of electricity a year, offsetting 100% of the building’s electrical-energy consumption. It will not only save taxpayers an estimated $22,000 annually but also reduce greenhouse gas emissions equivalent to 272 metric tons of carbon dioxide. (We’ll also sell back an additional 29,000 kilowatt hours to ComEd annually with its net-metering program.)

Our goal is to get to “net zero,” but we can’t get there alone. We need your help to get this building and others like it to generate as much energy as they consume.
That’s why we’ve created the green-energy endowment fund to help implement conservation efforts at the fleet building and similar structures. To find out how you can be a part of this bright future, visit

Board of Commissioners Meetings

For the safety of visitors as well as staff, until further notice, all Board of Commissioners meetings will be online only. You can link directly to live streaming video from the Forest Preserve District’s Facebook page at and from

Details on how to submit public comments or watch recordings of previous meetings and links to agendas and minutes are under “Our Board.”

Normally, commission meetings are at 8 a.m. on the first and third Tuesdays of the month; planning sessions, 8 a.m. on the second and fourth Tuesdays. At both the board hears public comments and staff reports, discusses business, and votes on agenda items.


Easier Access for Fans of Waterfall Glen

A new lot in southeast Waterfall Glen near the Rocky Glen waterfall area and the intersection of Cass Avenue and Bluff Road will bring much-needed parking relief and improved safety for forest preserve visitors.

The 2019 certified master-plan project will add parking for 175 cars, create a 0.3-acre picnic area, allow for future flush restrooms, improve trail access, and reduce many traffic conflicts near the popular intersection.

The design will be in tandem with ongoing natural resource restoration work, which will minimize disruptions to the preserve, improve public safety, and enhance the overall visitor experience.

The Forest Preserve District anticipates to open the lot by the last week of October 2022.


Collections Corner

coyote and owl mounts on display at Fullersburg Woods Nature Education Center

At Fullersburg Woods Nature Education Center you’ll see a series of mounts — birds, a coyote, an American mink — that offer a look at some of the native animals that live in the preserves but may be rarely seen. But like other assets in the Forest Preserve District’s collection they require care and maintenance to keep them from naturally degrading.

Taxidermy cleaning is a careful and delicate process that takes a lot of time and patience (and more than just a dust rag). To protect the mount and the person cleaning it, it’s important for the handler to always wear gloves. Older mounts made in the ‘80s and earlier used toxic chemicals in the tanning process, and oils from human hands can damage fur or feathers.

A special HEPA vacuum with a control for the suction gently removes dust and other fine particles. A Q-tip dipped in ammonia-free glass cleaner removes elements from glass eyes and birds’ feet.

To view these remarkable pieces and other natural-history-related exhibits, plan a visit to Fullersburg Woods Nature Education Center. It’s open Monday – Saturday 10 a.m. – 3 p.m. and is closed on Sundays and select holidays.
