US - Estimates of Potential Grizzly Bear Habitat Quality

This map shows estimates of potential grizzly bear habitat quality, based on roads, human population density, urban centers, and greeness (a metric derived from satellite imagery that may be related to the distribution of prey). Carlos Carroll provided data and analysis for this map. Source habitat is habitat that produces a surplus number of individuals (i.e., reproduction exceeds mortality), while sink habitat produces at a deficit (i.e., mortality exceeds reproduction).
