Thorn Creek Nature Preserve is a natural area of over 1000 acres jointly owned by University Park, Park Forest and the Forest Preserve District of Will County.  A Management Commission was formed in the 1970’s, made up of the landowners plus Friends of Thorn Creek Woods, the citizens group responsible in large part for preservation of these woods. Together they manage this large dry mesic oak hickory forest dominated by 150-year old white and red oak trees with a rich understory of native shrubs, rare plants and spring wildflowers.
