The U.S. Fish and Wildlife Service (USFWS) is a federal agency within the Department of the Interior. It is responsible for the management and conservation of fish, wildlife, and their habitats. The agency works to protect endangered species, restore ecosystems, and ensure sustainable use of natural resources across the United States. USFWS also oversees the National Wildlife Refuge System, which provides protected areas for wildlife and public enjoyment. The agency collaborates with state and local governments, non-profit organizations, and private landowners to promote conservation efforts and educate the public about the importance of biodiversity and habitat preservation.
