Abstract

The Illinois list of endangered and threatened vascular plant species identifies 315 species of plants as being in danger of extermination from Illinois. An inventory of specimens of endangered and threatened species housed in the herbarium of Northern Illinois University was conducted and 30 specimens of 22 endangered species and 9 specimens of 7 threatened species were found housed therein. A list was compiled, based on habitat and distribution information, of endangered and threatened plant species with possible occurrence in the study areas. The study areas were surveyed for habitat types present and categorized according to species likely to occur there. An inventory was conducted of Illinois endangered and threatened vascular plant species on selected public lands in DeKalb and Ogle Counties, Illinois. One endangered species, Rusty Woodsia (Woodsia ilvensis) and one threatened species, Ginseng (Panax quinquefolius) were found to occur in the study areas.
