Region 3 Candidate Species

PDF version


These plants and animals have been sufficiently studied, and the U.S. Fish and Wildlife Service has decided that they should be proposed for threatened or endangered status. The listing priority number indicates the general order in which they will be proposed. Within each Region, the pace at which new listing proposals are completed depends upon the funding appropriated by Congress to the listing and classification portions of the FWS budget. (Bold type indicates states that are within Region 3.)
