The United States Department of the Interior (DOI) is a cabinet-level department of the federal government, responsible for the management and conservation of most natural resources and cultural heritage within the U.S. It was established in 1849 to oversee public lands and protect them from exploitation. The DOI includes several agencies such as the National Park Service, the Fish and Wildlife Service, the Bureau of Land Management, and the Bureau of Indian Affairs, among others. These agencies work together to ensure the conservation and sustainable use of natural resources, preserve cultural heritage sites, manage wildlife populations, and support tribal governments in providing services to Native American communities. The department is headed by the Secretary of the Interior, a member of the President's cabinet.
