The 997-acre Fults Hill Prairie State Natural Area is owned and managed by the Illinois Department of Natural Resources. Most of this unique natural area was purchased between 1970 and 1976. From the uplands of Fults Hill Prairie Nature Preserve to the lowlands of Kidd Lake Marsh State Natural Area, a variety of plants and animals can be found, some common and some found nowhere else in the state.
Fults Hill Prairie Nature Preserve consists of 532 acres of uplands and includes woodland, prairie and glade communities. It has the largest complex of high-quality loess hill prairies in Illinois. Prairies once were the dominant natural community in Illinois. The Illinois Nature Preserve system was established to give the highest level of protection to the state's few remaining high quality natural areas; this site was dedicated as a preserve in 1970. In 1986 it was recognized federally by the U.S. Department of Interior as a National Natural Landmark.
Kidd Lake State Natural Area is an example of the once expansive wetlands of the Mississippi floodplain known as the American Bottoms. The marsh historically was part of an 800-acre lake bed, and once was home to a variety of wetland birds, some now rare in Illinois. It is an important rest stop for migrating waterfowl and continues to provide critical habitat to a diverse range of birds, as well as amphibians and reptiles.
Visitors are welcome, but please help protect the area by not disturbing or removing anything. All natural features are protected by law.
We hope you enjoy your stay. Remember, take only memories, leave only footprints.
