PAD-US 3.0 Download data by Department of the Interior (DOI) Region Shapefile

The Protected Areas Database of the United States (PAD-US) version 3.0 dataset was clipped to the 12 unified regional boundaries for the Department of the Interior (DOI) to provide data downloads for each of the regions. The unified regional boundaries are primarily based on a science-based approach to promote management efficiencies. The unified regions provide better management on an ecosystem basis to include critical components such as wildlife corridors, watersheds, and trail systems.
