Report Endangered and Threatened Species

The Illinois Natural Heritage Database Program needs your help to keep our database current. We track all endangered and threatened species (E&T species) within the state of Illinois. We welcome and encourage you to report your observations of listed species. For birds, we only track observations with evidence of breeding (nests, eggs, young, adults bringing food to the nest, etc.).
