PAD-US, how is it built = July 2016.jpg
Detailed Description
USGS integrates data from a network of state and federal stewards, along with national non-governmental organization lands (for example, The Nature Conservancy, The Trust for Public Land, Ducks Unlimited) and conservation easements (from the National Conservation Easement Database, NCED) to produce PAD-US and related globally relevant products (for example, submissions to the World Database for Protected Areas, WDPA).
