Wolf Road Prairie
An Illinois Nature Preserve
Wolf Road Prairie is a remnant of the prairie and savanna landscape that once graced much of northeastern Illinois. At this site, a freshwater marsh dominated by sedges and cattails occupies the northern half while high-quality mesic prairie occurs throughout much of the balance of the site. The prairie is dominated by tall grasses like big bluestem and Indian grass and is festooned with a variety of colorful and interesting flowers including blazing stars, shooting stars, hoary puccoon, rattlesnake master, prairie phlox, prairie dock, and compass plants. The remnant oak savanna is restricted to a narrow corridor along 31st Street and is dominated by open-grown burr oaks with carpets of wild geraniums and wild hyacinth.
Visitors are welcome, but please protect this nature preserve by remaining on the trail and by not disturbing or removing anything. The sidewalks that serve as trails are a telling reminder that this site was once targeted for development. Plants and animals are protected by law. Wolf Road Prairie Nature Preserve is owned by the Forest Preserves of Cook County, Save the Prairie Society, and the Illinois Department of Natural Resources.

Excerpt from the Forest Preserves of Cook County: "The southern portion of Wolf Road Prairie is crisscrossed with sidewalks from an abandoned 1920s subdivision. When development threatened again in the 1970s, concerned citizens bought the first parcel of what is now an 82-acre Illinois Nature Preserve. The savanna, wetland and rare remnant black soil prairie landscapes that make up this stunning preserve are home to more than 360 native plant species."(Submitted on April 24, 2024, by Sean P.
