MOUNTAIN ASH (Sorbus americana)
SITKA MOUNTAIN ASH (Sorbus sitchensis)
GREENE MOUNTAIN ASH (Sorbus scopulina)
Other names: none, other than mountain ash, or ash.

VERY POOR

The Sorbus genera are small shrub like trees found in the northern part of the adjacent states and Alaska. They seldom reach tree size. They are hardy shrubs, smooth barked, with white flowers and red berries. The wood decays quickly. 

None of these species have been recorded or recovered as a bearing tree, thus no report. 

Do not use as a bearing tree unless nothing else is available. Bark scribing is probably the only way to mark a mountain ash if it is utilized. Painting would be a must.
