The Green River State Wildlife Area is a wildlife restoration area popular among hunters, hikers, birders and other outdoor enthusiasts. Topography of the 2,565-acre area varies from flat to gently rolling. Swampy slough areas dominate nearly a third of the acreage, but the remaining portions are prairie restorations, open fields, cultivated areas or timberlands. Many of these areas are planted and managed to provide more food and cover for wildlife. Native prairie plants are found in many portions of the Green River State Wildlife Area.
Acquired by the state of Illinois in 1940, with the assistance of funding from the Federal Aid in Wildlife Restoration Act, Green River State Wildlife Area is located about 6 miles northwest of Ohio, IL, off IL Rt. 26.
We hope you enjoy your stay. Remember, take only memories, leave only footprints.
