PAD-US (CBI Edition) Version 2.1 is limited to the continental U.S., Alaska, and Hawaii. It does not include protected areas data for U.S. territories at this time.
PAD-US (CBI Edition) Version 2.1 is a preliminary pass at assigning establishment dates for the national database, with a primary focus on federal lands held by Bureau of Land Management, USDA Forest Service, US Fish & Wildlife Service and National Park Service. A total of 2088 protected areas records were assigned establishment dates in this version.
