Whitebark Pine Distribution.

A) The predicted contemporary distribution of whitebark pine (P. albicaulis) in the western United States and southwestern Canada using a plant-climate model (Rehfeldt et al. in press). Pixel colors represent votes for whitebark pine occurrence. The black drawn lines represent predicted metapopulations of whitebark pine based on chloroplast microsatellite molecular markers (Richardson et al. 2002). B) The predicted 2030 distribution of whitebark pine using the average of two general circulation models.
