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. Over 130 variables were evaluated for each species, though seldom will all variables have data. This is a start, but a tremendous amount of information still needs to researched and/or compiled. The variables are presented in the input form, used in the compilation process, and described in the document, input form descriptors.

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; this current effort is to make the data more readily available via the web. Thanks to Anantha Prasad (USDA Forest Service) for preparing the Javascript for this site.

Please realize that the database is far from complete; much of the information just is not available. Common names are not available for all species, and many species have more than one common name. Here, only one (if available) is given; other common names are presented in the data for individual species.
