About this Collection

The U.S. Fish and Wildlife Service and the National Oceanic and Atmospheric Administration's National Marine Fisheries Service share responsibility for administration of the Endangered Species Act (ESA). We have issued internal guidance and national policies to promote efficiency and nationwide consistency in implementing the ESA to conserve and recover listed species of plants and animals native to the United States and its territories.

Below you will find links to summaries of our major policies, sorted by the associated section of the ESA.
