Welcome to the site for volunteers at Cranberry Slough Nature Preserve!
Cranberry Slough, known for its unique peat bog community populated by sphagnum moss and other plant survivors from post-glacial times, was dedicated as the fifth nature preserve of Illinois in January, 1965. Secluded in southwestern Cook County, Illinois, its 372 acres are nestled within the larger 14,000-acre Palos Preserves, which are laced together by 35 miles of meandering multi-use trails made of packed earth and crushed limestone.
Grey tree frogs, spring peepers, & green frogs should be calling in the background. The audio control is here:
