The Illinois List of Endangered and Threatened Species is reviewed about every five years by the Illinois Endangered Species Protection Board (ESPB). To date it has evaluated only plants and animals of the US state of Illinois, not fungi, algae, or other forms of life; species that occur in Illinois which are listed as endangered or threatened by the U.S. federal government under the Endangered Species Act of 1973 are automatically listed as such for the state of Illinois.
