A key task was the development of seamless animal-habitat models for all terrestrial vertebrate species for the region. Through coordination from the U.S. Geological Survey’s Gap Analysis Program (GAP) and the collaborative efforts of participating state institutions, 819 seamless habitat models were completed in September 2005. These data are made available to the public with ‘provisional’ status by the SWReGAP consortium of institutions responsible for their development. Following a peer review process meeting USGS GAP requirements, these data will be provided with ‘final’ status.

Ranges are coded based categories of historic distribution, breeding. and seasonality.  For more information on the range coding click here.
