The 997-acre Thorn Creek Woods Nature Preserve was acquired between 1974 and 2006.
The preserve is part of the Thorn Creek preservation system, which conserves approximately 1,600 acres.
The preserve is jointly owned and managed by four Thorn Creek Woods Management Commission members: the Forest Preserve District, the Village of Park Forest, the Village of University Park and the Illinois Department of Natural Resources.
An 884-acre portion of the site was dedicated as an Illinois Nature Preserve in 1978, 1993 and 2001. This dedication provides permanent protection for the preserve's natural resources.
