- •
We model the climate niche of Pinus ponderosa and Pseudotsuga menziesii varieties.
- •
Classification errors were less than 5% and were mostly false positives.
- •
Niche space was mapped for the decade surrounding 2060 using GCM ensemble output.
- •
Projected impacts were more severe for P. ponderosa than for P. menziesii.
- •
Projections were dire for the varieties occurring in Mexico.
