Potential for maladaptation during active management of limber pine

Science Spotlights Posted on: September 12, 2016
Active management is needed to sustain healthy limber pine (Pinus flexilis) forests in the southern Rocky Mountains as they are threatened by the interaction of the mountain pine beetle (Dendroctonus ponderosae) epidemic, climate change, and the spread of the non-native pathogen that causes white pine blister rust disease (Cronartium ribicola). Movement of seedlings with disease resistance from northern to southern Colorado may result in planting failure. Identification of genotypes resistant to white pine blister rust in the southern Rockies is needed at the finer scale of a national forest scale rather than the region.
