The Illinois Plant Information Network (ILPIN) was designed to provide many different types of information about ALL of the vascular plant taxa found in Illinois. At this site, you can search on a species (by scientific or common name), and retrieve all the information we have compiled on the species, as well as a map of its known distribution among the counties in Illinois.

ILPIN was developed by Louis Iverson (liverson@fs.fed.us), currently employed by the USDA Forest Service, 359 Main Road, Delaware, OH 43015. Data were complied from numerous sources by David Ketzner and Jeanne Karnes, at the Illinois Natural History Survey. Nomenclature for taxa follow: Mohlenbrock, R.H. 1986. Guide to the vascular flora of Illinois. Southern Illinois University Press, Carbondale, IL.

Work was conducted and sponsored by the Illinois Natural History Survey, 607 E. Peabody, Champaign, IL 61820. Funding was also provided by the Illinois Department of Transportation. The work was primarily done during the period 1984-1992;
