Protected Areas

PAD-US is America’s official national inventory of U.S. terrestrial and marine protected areas (List of National Geospatial Data Assets) that are dedicated to the preservation of biological diversity and to other natural, recreation and cultural uses, managed for these purposes through legal or other effective means. The latest version of the Protected Areas Database of the U.S. (PAD-US 2.0) is now available. This update is a significant step towards meeting our goal of creating a spatially explicit inventory that lets any user – from the general public to professional land managers – know exactly what lands are protected anywhere in the United States and allows them to easily use this inventory in conservation, land management, planning, recreation, and other uses.
