The U.S. Department of the Interior's (Department) Natural Resource Damage Assessment and Restoration Program (Restoration Program) manages the confluence of the technical, ecological, biological, legal, and economic disciplines and coordinates the efforts of six bureaus and three offices to accomplish the mission.  The Restoration Program has a nationwide presence encompassing nearly the full span of natural and cultural resources for which the Secretary of the Interior has trust responsibility.  Each bureau has its unique natural resource trusteeship and brings its expertise to bear on relevant sites.  The Restoration Program is a truly integrated Departmental program, drawing upon the interdisciplinary strengths of its various bureaus and offices.

	The Bureau of Indian Affairs administers and manages over 66 million acres of land held in trust by the United States for American Indians, Indian Tribes, and Alaska Natives and provides assistance to 562 Federally recognized Tribal governments to help protect water, natural resources, and land rights.
	The Bureau of Land Management administers 262 million acres of land, located primarily in 12 western states, sustaining the health, diversity, and productivity of these public lands for the use and enjoyment of present and future generations.
	The Bureau of Reclamation, working primarily in the 17 Western States, manages nearly 9 million acreas associated with reclamation projects to protect local economies and preserve natural resources and ecosystems through the management and effective use of water resources.
	The U.S. Fish and Wildlife Service conserves, protects, and enhances fish, wildlife, and plants and their habitats and manages the 96-million-acre National Wildlife Refuge System for the continuing benefit of the American public, providing primary trusteeship for migratory birds and threatened and endangered species.
	The National Park Service preserves the unimpaired natural and cultural resources and values of the 84-million-acre national park system and conserves the scenery, natural and historic objects, and wildlife of the park system for the enjoyment, education, and inspiration of current and future generations.

In addition to the five trustee bureaus above, the Office of Policy Analysis, the Office of the Solicitor, and the U.S. Geological Survey (USGS) play key roles in making the Restoration Program a fully integrated Departmental program.  The Office of Policy Analysis provides economic analytical expertise to the Restoration Program at both the national policy and the individual case management levels, the Office of the Solicitor provides legal advice, and the USGS provides technical scientific support.  The Office of Environmental Policy and Compliance provides regional coordination support as well as a link to response and remedial activities associated with oil or chemical releases.
