List Of Plant Species 
At Three Natural Blacksoil Prairie Remnants 
In Central Illinois

Kenneth R. Robertson

Prior to settlement by people of European descent, more than 60% of the land area of Illinois was in prairie vegetation, more than 22 million acres. Some counties in Central Illinois were more than 90% prairie. Today, only about 2,300 acres of high quality, unplowed prairie remains in Illinois, mostly in very small, isolated remnants. Three noteworthy examples of such remnants are: Loda Cemetery Prairie Nature Preserve in Iroquois County, Prospect Cemetery Prairie Nature Preserve in Ford County, and Weston Cemetery Prairie Nature Preserve in McLean County. These three prairies are all mesic blacksoil prairies, about 5 acres in size, and officially dedicated Illinois Nature Preserves; the plants and animals are protected. These examples were originally pioneer cemeteries established on virgin prairie.

The soil that developed under blacksoil prairies is one of the most agriculturally productive soils in the world, and very nearly all prairies were plowed. Because blacksoil prairies are so rare today, it is often difficult to find out what plant species occur in this habitat. Over the years, we have put together a list of flowering plants for these three prairies. This list can serve as a model for those planing prairie restorations. Each prairie can be considered a sample plot on the original vast prairie, and the combined species list for all three remnants is an approximation of the diversity of plants that would have been found on virgin mesic blacksoil prairies in Central Illinois. The information is from unpublished files at the Center for Biodiversity, Illinois Natural History Survey. Most data is from the work of Paul Shildneck, Kenneth R. Robertson, and John Taft.

The numbers in the column entitled "C/C" are the Coefficient of Conservatism as used in this reference: J. B. Taft, G. S. Wilhelm, D. M. Ladd, and L. A. Masters. 1997. Floristic quality assessment for vegetation in Illinois, a method for assessing vegetation integrity. Erigenia (Journal of the Illinois Native Plant Society) 15: 1-95. This coefficient ranges from 0 to 10; species with lower numbers are "weedy" and found in disturbed habitats, while species with higher numbers are found primarily in undisturbed habitats. Only native plants are assigned numbers.
