The southern portion of Fourth Lake Forest Preserve near Lindenhurst, IL contains a 200-acre cattail-dominated marsh. The Lake County Forest Preserves is developing a controlled burn management plan for a 60-acre portion of this cattail marsh. In order to implement this plan, a 30 feet wide by 6700 feet long burn break is to be installed by herbicide-killing of all vegetation within the alignment and reducing dead stem heights to less than 18 inches. Dead stem heights can be reduced by compression/compaction or cutting dead biomass by vehicle tracking, pulling/dragging weighted rollers, or manual cutting. All lanes will be cut made through cattail-dominated areas. Path alignments will be field flagged by Owner and review with contractor.
