The 2,492-acre Waterfall Glen Forest Preserve in Darien is one of the most ecologically impressive parcels of open space within the Forest Preserve District of DuPage County, if not northern Illinois.
The ridges and scattered potholes that make up the topography of Waterfall Glen — and most of the county — are the result of one geological event, the Wisconsin Glacier. In fact, the entire Des Plaines River Valley was formed by glacial meltwaters and drainage from a postglacial lake that covered most of the Chicagoland area.
Today, Waterfall Glen’s prairies, savannas, and oak-maple woodlands contain 740 native plant species, 75 percent of all the plants known to grow naturally in DuPage County. As a result of this rich variety, over 300 species of mammals, birds, fish, amphibians, and reptiles and another 300 of invertebrates use the forest preserve either year-round or during their migrations.
The District will close a section of Waterfall Glen's Centennial Trail for one day while contractors use a helicopter to apply herbicide to common reed, an invasive plant that has taken over a section of the trail. The actual day of the application will depend on the weather, but it will be sometime between Aug. 19 and 31. The District will post "Trail Closed" signs on barricades to block the trail the morning of the application and will reopen the trail the next day.
An eastern area of the Centennial Trail has been closed by the Metropolitan Water Reclamation District of Greater Chicago (MWRD) for the Deep Tunnel construction in McCook. Please follow the detour signage. Additional information on the project can be found at www.mwrd.org or email: email@example.com.
The District has removed considerable amounts of buckthorn, honeysuckle and other select weedy, invasive trees and shrubs from Kettle Woods since winter 2014. Click here for more information on the project.
