The Gap Analysis Project (GAP) is a core activity of the Biogeographic Characterization Branch. GAP produces and manages a set of species habitat distribution maps based on the 30-meter GAP land cover product. GAP species and subspecies are best represented within another ScienceBase collection that documents and houses the 2001 release of CONUS habitat maps. The items in that collection provide essential details for the TIR process within their identifiers (species names, GAP identifiers, ITIS TSN, and other related identifiers).
