The U.S. Fish and Wildlife Service and numerous conservation organizations observe Endangered Species Day on May 20, 2011, to recognize conservation efforts underway across the nation aimed at helping America’s imperiled species.
To date, the Endangered Species Act, which became law in 1973, has helped to prevent the extinction of hundreds of species. Co-administered by the Service and National Oceanic and Atmospheric Administration, the purpose of the Act is to conserve imperiled species and the ecosystems upon which they depend.
