Improving the Nations Data on Natural Resources and Parklands
The PAD-US section of the website describes the land inventory database and efforts to improve how we track U.S. lands set aside for conservation, open space, recreation and other natural resource uses.

The Data Portal section of the web site contains a wide range of information on protected land inventories maintained by indivdual states, federal agencies and national non-profits. You are invited to help improve this information by directly contributing information about available protected areas data.

The PAD-US Partnership section of the web site describes the 2008-2010 design project to create a recommendation for a national inventory of protected areas.
