The Fish and Wildlife Service (FWS) is a U.S. government agency under the Department of the Interior. Its primary mission is to conserve, protect, and enhance fish, wildlife, and their habitats. The FWS manages national wildlife refuges, enforces federal wildlife laws, and oversees the Endangered Species Act, which aims to protect species at risk of extinction. In addition to conservation efforts, the FWS conducts research and provides education about wildlife and ecosystems. The agency also collaborates with state and local governments, non-profit organizations, and private landowners to promote sustainable practices that benefit both wildlife and people.
