Interpretation Guide
Mountain maple is narrowly distributed (1.2% of area), sparse, and very low in abundance across the northern tier, and FIA does not even map its territory over most of its southern and Appalachian range mapped by Little in the late 1960s. Consequently, it has a very poor reliability model depicting substantial loss in habitat, even though modeled future habitat does retain habitat to the southern range of Little. It does however, score as highly adaptable, resulting in a rating of poor capacity to cope.
Family: Aceraceae
Guild: understory tolerant
