The Protected Areas Database of the United States (PAD-US) is the official inventory of public parks and other protected areas in all U.S. states and territories. This growing database contains more than three billion public land and marine acres managed by nearly 15,100 agencies and nongovernmental organizations, covering 200,000 separate parks and protected areas. Explore the different types of public lands in the United States. National, state, regional, and local organizations all manage protected lands. From the PAD-US map you can identify protected areas managed by various federal agencies such as the Bureau of Land Management, the U.S. Forest Service, and the National Park Service. Or you can view information for recreational areas such as State Parks. Navigate through these lands using an interactive mapper.
