A habitat improvement project at Herrick Lake Forest Preserve will cause temporary trail closures at the preserve near Wheaton.

The work will begin Dec. 20 and require closing a section of the Green Heron Trail through April 2022, between the spur leading to Warrenville Road and the intersection to the Danada-Herrick Lake Regional Trail to the northeast. There will also be intermittent closures of the spur to Warrenville Road.

The project involves removing aggressive plant species that threaten the native plant and native wildlife species that rely on the area. Crews will cut and remove invasive trees and shrubs and apply herbicides to the cut stumps so the plants can’t grow back.
