Interpretation Guide
Black ash is widely distributed (5.8% of area), sparse, but high IV and abundant in the swampy land of the northern forests which for the most part, has not yet been decimated by EAB. Its northern, cold climates hopefully could help slow the spread of EAB, but the species is quite susceptible when attacked. Our medium reliable models suggest no change in suitable habitat in the future. Our metrics suggest a poor overall capability for this species, but again, EAB is likely to dictate its potentials.
Family: Oleaceae
Guild: opportunistic, fast-growing understory tolerant
