Interpretation Guide
Quaking aspen is widely distributed (10.3% of area), dense, and with high IV and very abundant across the northern tier of forests with a highly reliable model suggesting a small decrease in suitable habitat, especially under RCP 8.5. It has medium adaptability, being able to colonize early successional habitats, and because of its high abundance, even though it is a decreaser, it rates an overall class of fair capability to deal with the changing climate. SHIFT also rates it as a decent species for infill planting.
Family: Salicaceae
Guild: pioneer, moist-site intolerant
Functional Lifeform: medium-size to large deciduous tree
