"Keeping Common Species Common"
GAP Analysis originated in Idaho in the late 1980's as a system for assessing the distribution of native plant and animal distributions in relation to land stewardship.  Since then, GAP has grown to a federally funded program under the Biological Resources Division of the United States Geological Survey.  GAP's main objectives are to: map current land cover, predict the distribution of vertebrate species, document the representation of vertebrate species and land cover types in areas managed for the long-term maintenance of biodiversity, and provide this data to the public. This is accomplished through the cooperation of many state and federal organizations. For more information on GAP, please visit the National Gap Analysis Program website.
