Endangered Species

Nothing is more priceless and more worthy of preservation than the rich array of animal life with which our country has been blessed.  It is a many faceted treasure…and it forms a vital part of the heritage we all share as Americans.
President Richard Nixon – Statement upon signing the Endangered Species Act, 1973

Endangered Species Program

Preventing Extinction. Achieving Recovery

The Endangered Species Act (ESA) provides a critical safety net for America’s native fish, wildlife and plants. This landmark conservation law has prevented the extinction of hundreds of imperiled species and helped many others recover. The U.S. Fish and Wildlife Service (USFWS), along with our sister agency, the National Marine Fisheries Service (NMFS), is responsible for implementing the ESA nationally. We continuously strive towards making implementation of the ESA less complex, less contentious, and more effective. Ultimately we want to work with you and our partners to accelerate recovery of threatened and endangered species, and make it easier for people to coexist with listed species.
