This spatial analysis of the Protected Areas Database of the United States (PAD-US) was performed to provide land managers and decision makers with a general summary of management for biodiversity protection, natural resource management, and recreation access. The PAD-US inventory is an aggregation of data from managing entities representing the U.S. protected areas network and contains many overlapping boundaries. The associated vector analysis files were created to remove overlapping features and "flatten" the data to facilitate spatial analysis and the calculation of area statistics in summary reports. The vector analysis files also allow for other applications that require a representation of overall protection status without overlapping designation boundaries. GAP Status Codes and Public Access Categories are used to calculate total acreage, acres by managing agency, and percent protection status or percent access, respectively. Summaries are available for various units of interest to stakeholders: all U.S. States and Territories, U.S. States, the Contiguous U.S., and by State, Department of the Interior Region, Congressional District, County, Hydrologic Unit Code 12, EcoRegions I-IV, Landscape Conservation Cooperatives, and Urban Areas.
