Governance & Policy
US Endangered Species Act
Definition
The Endangered Species Act, enacted in 1973, directs US federal agencies to conserve species listed as endangered or threatened. It prohibits the "taking" of listed species, requires designation of critical habitat, obliges federal agencies to consult on actions that may affect listed species, and mandates recovery plans.
