What We Do



Interior studies, manages, protects, and provides access to these significant resources:

  • More than 35,000 miles of coastline
  • 34 million acres in 84 marine and coastal National Parks (managed by the National Park Service)
  • 180 marine and coastal National Wildlife Refuges (managed by the U.S. Fish and Wildlife Service)
  • 1.7 billion underwater acres of Outer Continental Shelf (managed by the Bureau of Ocean Energy Management (BOEM) and Bureau of Safety and Environmental Enforcement (BSEE)
  • 1,100 miles of coastline of the California Coastal National Monument (managed by the Bureau of Land Management)
  • Hundreds of thousands of square miles in marine national monuments (managed by the U.S. Fish and Wildlife Service) including the Papahanaumokuakea Marine National Monument (co-managed by the U.S. Fish and Wildlife Service, NOAA and the State of Hawaii)
  • Marianas Trench Marine National Monument (managed by the U.S. Fish and Wildlife Service)
  • Pacific Remote Islands Marine National Monument (managed by the U.S. Fish and Wildlife Service)
  • Rose Atoll Marine National Monument (managed by the U.S. Fish and Wildlife Service)

Interior uses science-based management to increase our understanding of natural resources for informed responsible use and effective conservation practices. Interior experts provide data, tools, and information to inform and support multiple levels of leaders and decision makers.  

Interior conducts diverse scientific and resource monitoring programs coordinated with other Federal agencies and non-federal partners, to manage energy, cultural, wildlife, and natural resources for the Nation. Through extensive ocean, coastal, and Great Lakes research, Interior works to predict, assess, and manage coastal and marine resources.

Interior manages resources at the landscape and ecosystem scale. By addressing resource management at the landscape scale, programs work across political boundaries and through community engagement to promote health, reduce risk, and support sustainable watersheds, from uplands to coastal waters. Land-use practices provide corridors for wildlife and ensure water quality, quantity and natural resources are resilient and able to adapt to changing conditions.

Interior collaborates, coordinates and supports other Federal agencies, States, Tribes, and a wide array of partners to conduct critical scientific research and manage upland watersheds, coastal and estuarine ecosystems, continental shelf and deep ocean environments and the natural resources that exist in them. These include endangered and invasive species, wetlands, watersheds, refuges, monuments, parks, coastlines, seashores, and open ocean areas in all 50 states and U.S. territories in the Atlantic, Pacific, Arctic, Gulf of Mexico, Great Lakes and the Caribbean Sea.

Interior co-leads the U.S. Coral Reef Task Force with NOAA that includes 10 other Federal agencies, states, Territories, Commonwealths and three Freely Associated States to preserve and protect coral reef ecosystems. http://www.coralreef.gov/

Interior supports The National Ocean Policy- Interior is implementing the National Ocean Policy through leadership involvement with the National Ocean Council, the Ocean Resource Management –Interagency Policy Committee (ORM-IPC) and the Ocean Science and Technology – Interagency Policy Committee (OST-IPC). Interior is responsible for actions that address the nine priority objectives of the vision of an America whose stewardship ensures that the ocean, coasts, and the Great Lakes are healthy and resilient, safe and productive, and understood and treasured so as to promote the well being, prosperity, and security of present and future generations.http://www.whitehouse.gov/administration/eop/oceans/policy

Interior provides access and recreational opportunities to a wide array of coastal,  and ocean environments. Public access to these resources fosters understanding and awareness by connecting present and future generations to diverse natural and cultural treasures.

Interior participates in Regional Ocean Partnerships to strengthen and enhance regional initiatives and support partners with resources and expertise.
