The Southwest Regional Gap Analysis Project (SWReGAP) is an update of the Gap Analysis Program's mapping and assessment of biodiversity for the five-state region encompassing Arizona, Colorado, Nevada, New Mexico, and Utah. It is a multi-institutional cooperative effort coordinated by the U.S. Geological Survey's Gap Analysis Program. Data sets are made available to the public by the SWReGAP consortium of institutions responsible for their development, including the Southwest Node of the NBII.

The NBII Program is administered by the Biological Informatics Program of the U.S. Geological Survey
