Nature Preserve Area: 
Location and Access:

Special Note: Trails and parking are available at this preserve.

Cranberry Slough typifies the rolling topography of the Valparaiso Moraine of the Northeastern Morainal Division of Illinois. Formerly, the site supported a mosaic of prairie and oak savanna. Currently, the steep slopes support both young upland forests and remnants of degraded prairie. The kettleholes currently support sedge meadow and marsh communities. Water levels have been held at artificially high water levels by a shallow dams so consequently, beaver and other wetland wildlife have been recorded from this preserve.
