Inscription.
Wolf Road Prairie Nature Preserve has been formally dedicated as a sanctuary for native plants and animals. It is being maintained and restored to its natural condition so that present and future generations can see the Illinois landscape as it appeared in the past. This living example of our natural heritage is valuable for scientific studies and provides habitat for rare plants and animals.

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.

By 1978, less than 2,300 acres of high quality prairie remained in the entire state. Most of the undisturbed prairie sites today are found along railroad rights-of-way, in pioneer cemeteries and in places that are not suitable for farming.

incrementally easier to visit. One off of 31st Street southwest of here is next to a small wayside, albeit along a busy road; another is at the corner of Wolf Road and Constitution Drive north of here, about 300 feet (down a much quieter Constitution Drive) from the Franzosenbusch Prairie House. Another marker with an identical name, in front of the Franzosenbusch house, has shorter text and goes a bit more into the history of the preserve.

Excerpt: "Wolf Road Prairie was subdivided into nearly 600 lots for housing and commercial development in the l920’s. Although sidewalks were laid in the south 40 acres of the preserve, the project failed during the Great Depression of 1929. Water and sewer lines were never installed, and the prairie remained largely undisturbed to the present day. Private ownership was fragmented and changes in Westchester zoning requirements did not allow for construction on the small city-size lots. Little by little the state and county acquired

land in the prairie, sometimes one lot at a time."
