Downers Grove Wetland Mitigation Bank – DuPage County Department of Environmental Concerns

Work at this 15 acre site consisted of the establishment of a wet meadow wetland mitigation bank. The north eastern cell of the bank area contained a small woodland dominated by garlic mustard and buckthorn. As part of the bank establishment, ENCAP, Inc. cleared the buckthorn, eliminated garlic mustard, and planted specified trees and shrubs. ENCAP, Inc. completed installation in 2002 and has since completed numerous management activities including:

  • Planting of native trees and shrubs
  • Selective herbicide application of non-native perennial species
  • Mowing and weed-whacking of non-native annual species
  • Prescribed burning
  • Non-native woody shrub removal

The site met U.S. Army Corps of Engineers, Chicago District performance standards in 2007. ENCAP continues to perform long term maintenance on the site for DuPage County.
