The 110-acre Egermann Woods Forest Preserve in Lisle is one of the few remaining presettlement oak forests in DuPage County. This project involves crews removing aggressive plant species from 87 acres of the preserve, which threaten the 347 native plant and 127 wildlife species that live there, some state-endangered or rare. The aggressive plant species keep sun and water from reaching the grasses, wildflowers, and oak and hickory seedlings that grow here. As a result, the variety of plants and animals is declining.
Crews will cut and remove invasive trees and shrubs and carefully apply herbicides to the cut stumps so these aggressive plants can’t grow back. They may also create and burn brush piles on site. Both the mature hickories and majestic oaks that grow among them will remain untouched, while promoting more germination of seedlings and wildflowers. The work is a board-certified master plan project, furthering the Forest Preserve District’s mission to preserve the flora, fauna and scenic beauty of DuPage natural areas.
Work will begin in December 2021 and take place primarily in December, January and February. It will take a few winters to complete. Crews may also do follow-up hand and mechanical work in the spring and summer from time to time.
The $364,000 project will be funded through the Forest Preserve District’s yearly appropriated construction and development funds.
