Interpretation Guide
American mountain-ash is narrowly distributed (0.5% of area), sparse, and low IV. It is rare in the northern portion of the region. Its low reliable model suggests a large loss in habitat, and its adaptability is also low such that its rating for capability to cope with a changing climate is very poor. Effect of SHIFT is neglibible.
Family: Rosaceae
Guild: understory tolerant, slow growing
