Abstract:
The question of whether the Endangered Species Act (ESA) “works†is an important part of the debate before Congress concerning both its annual appropriations and reauthorization of the Act itself. Information on the species that have been delisted or downlisted from the Lists of Endangered and Threatened Wildlife and Plants is often cited when judging the ESA’s success or failure. This report outlines the process and reasons for delisting or downlisting, and summarizes the 27 species delisted due to extinction, recovery, or data revision, and the 22 species that have been downlisted from endangered to threatened status due to stabilized or improving populations.
