(Illinois Endangered Species Protection Act)
  • "any species which is in danger of extinction throughout all or a significant portion of its range other than a species of the Class Insecta determined by the Secretary to constitute a pest whose protection under the provisions of this chapter would present an overwhelming and overriding risk to man"  (Endangered Species Act of 1973)

Threatened species

  • "any species of plant or animal classified as threatened under the Federal Endangered Species Act of 1973, P.L. 93-205, and amendments thereto, plus such other species which the Board may list as likely to become endangered in the wild in Illinois within the foreseeable future." (Illinois Endangered Species Protection Act)
  • "any species which is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range." (Endangered Species Act of 1973)
