construction work at Willowbrook

Construction Starts on Major Renovation
Phase at Willowbrook Wildlife Center

After a ground-breaking ceremony this summer at Willowbrook Wildlife Center, construction is fully underway on major improvements at the site, which will include a new visitor center.

After setting up on site, the Forest Preserve District contractor continues to prepare the area for concrete foundations for two new structures and concrete pads for additional animal enclosures. A new raptor flight barn will house rehab and resident raptors and include larger areas for short flights and observation. The carnivore enclosure will house the center’s resident bobcat as well as rehabilitating carnivores transitioning to release.

This phase should wrap up in spring, at which time animals on the exhibit trail will move into their new homes. The District’s consultant is hard at work on permits for the remaining phases of work, which will start south of the existing clinic after the resident animals have moved.

As temperatures drop and the seasons change, artifact displays change, too. For instance, Kline Creek Farm seasonally moves textiles and other pieces from display to storage to protect them from fluctuations in temperature and relative humidity in the 1890s farmhouse, which can dramatically shorten the life of some materials. Periodic rotation to a climate-controlled storage environment can also safeguard items from dangers such as light, dust, and mold.

These seasonal changes may take some textiles off display this time of year, but they allow Kline Creek Farm to instead interpret other historical artifacts related to winter life on the farm, such as the ice saw and ice hatchet.

Ice saws (pictured here) were used in the 1890s to cut blocks from frozen lakes. Ice hatchets were used to chip odd shapes from the resulting blocks so the blocks would fit tightly together in the icehouse, helping preserve the ice well into summer. Ice saws are common artifacts, but because the ice hatchet is not an easily recognizable tool (and has an odd shape not useful in woodworking), few remain.

This winter, follow the farm on TikTok or Facebook to see Forest Preserve District staff demonstrate ice harvesting and interpret other activities and relics of the past.


Habitat Work Continues at Herrick Lakerestored prairie at Herrick Lake

This winter, crews will continue habitat improvement work at the 887-acre Herrick Lake Forest Preserve by removing invasive shrubs and trees throughout oak, prairie, and wetland ecosystems. These efforts will create healthier habitats (including the already-restored prairie below) for the 545 native plant and 238 native wildlife species that live at the preserve — some state-endangered, state-threatened, or rare. When completed, the project will create a mosaic of 550 acres of restored habitat, one of the largest such areas in the county.

Trail fans should note, though, that the work will require closing a section of the Green Heron Trail and the spur leading to Herrick Road through mid-March. The Forest Preserve District will post signs to let visitors know where these stretches begin and end.


Work Begins at Fischer Woods

The Forest Preserve District will begin to revitalize oak habitats this winter at Fischer Woods Forest Preserve. The main goal will be to remove invasive shrubs and trees, such as European buckthorn and honeysuckle, which produce dense clumps of leaves. This impenetrable vegetation keeps sun and water from reaching the wildflowers and oak and hickory seedlings that grow below. As a result, the variety of plants and animals that live at Fischer Woods has been declining. Similar work throughout the Forest Preserve District has shown that not only plants but also populations of birds and butterflies can recover once the weedy vegetation is removed. This winter, crews will cut and mow invasive trees and shrubs and will carefully apply herbicides to the cut stumps so the plants can’t grow back. They may also chip trees and brush and create and burn brush piles.

Because equipment is large and will be moving at a fast pace, visitors may periodically see “area closed” signs. The Forest Preserve District expects work to wrap up by December 2025.


Expanded Parking at Waterfall Glennew parking lot at Waterfall Glen

Forest Preserve District visitors can now enjoy expanded access to the trails at Waterfall Glen thanks to a new 180-car parking lot off Bluff Road.

The lot, a 2019 certified master plan project, reduces pedestrian conflicts near the intersection of Cass Avenue and Bluff Road and improves access to the trails. The former 17-car lot could not adequately accommodate the increasing number of visitors to the Rocky Glen area, one of the more popular destinations at the preserve, and frequently resulted in overflow parking on Bluff Road and Cass Avenue. The project not only expanded spots by more than 10 fold but also rerouted the trail and installed a new trailhead. A future 0.3-acre picnic area will further enhance the site.

The new lot was open by Labor Day weekend, weeks ahead of its target completion date.
The project’s design was coordinated with an ongoing habitat restoration project at the preserve to lessen effects to natural resources, minimize disruption, and enhance the overall visitor experience. 


Grant to Benefit Blackwell Forest Preserveveery

The Forest Preserve District of DuPage County and the DuPage Birding Club jointly announced that the club awarded a $2,000 grant to the 501(c)(3) Friends of the Forest Preserve District of DuPage County to fund the planting of nearly 100 native tree saplings and shrubs near McKee Marsh at Blackwell Forest Preserve in Warrenville.

The grant will advance a restoration project already begun at the site, which included the removal of nonnative buckthorn and honeysuckle shrubs. Newly planted native trees and shrubs will increase the habitat’s biodiversity, provide needed vegetative structure, and restore resources for native and migratory birds that nest and forage in the woodland’s understory.

The Forest Preserve District expects it will take several years for the saplings and shrubs to reach maturity before the habitat provides the conditions required by understory-nesting birds.

District Celebrates Important Trail Connection

In October, the Forest Preserve District celebrated the opening of a new 1.7-mile section of limestone trail in Pratt’s Wayne Woods, an important connection between the forest preserve’s trails and the Elgin Branch of the Illinois Prairie Path.

The new trail segment marks the completion of the nearly 20-mile North Central DuPage Regional Trail, which spans northern DuPage County and connects the Elgin Branch of the Illinois Prairie Path on the west to Cook County’s Busse Woods in Elk Grove Village on the east. It includes side paths as well as on-road and off-street trails.

The final segment runs along the west side of Munger Road starting at Forest Preserve Drive, crosses Army Trail Road, and ends at Smith Road, where it connects to the Illinois Prairie Path.

The Forest Preserve District received $1.5 million in Surface Transportation Program funds and $152,000 from the federally funded locally programmed Transportation Alternatives Program for the construction of this final segment.
