Description of the substance

---Description---The Mountain Ash is not related to the true Ashes, but has derived its name from the similarity of the leaves.

In comparison to the true Ash, it is but a small tree, rarely more than 30 feet high. It belongs to the order Rosacece and is distinguished from its immediate relations the Pear, Crab Apple, White Beam and Wild Service Tree by its regularly pinnate, Ashlike leaves. It is generally distributed over the country in its wild state, but is also much cultivated as an ornamental tree.

Habitat and range.—The American mountain-ash occurs in swamps, low woods, or moist ground from Newfoundland south along the mountains to North Carolina and to Michigan. It is most abundant in the northern portion of its range.

Description.—This smooth-barked tree reaches a height of 30 feet with a trunk 18 inches in diameter. The leaves resemble those of the sumac, consisting of from 11 to 17 lance-shaped, pointed leaflets about 1 1/4 to 4 inches long. When young they are slightly hairy, both sides soon becoming smooth. The white flowers are borne from May to June in dense clusters measuring from 3 to 6 inches across. The flowers are followed later in the season by large, dense, showy clusters of bright-red berries about the size of peas, which give the tree a brilliant appearance.

Although ash berries are inedible to humans, they are a favorite of birds such as ruffed and sharptail grouse, and ptarmigan, and mammals such fisher and marten. Deer and moose eat the twigs.

IMPORTANCE TO LIVESTOCK AND WILDLIFE :
American mountain-ash is a preferred browse for moose and white-tailed
deer.  Moose will eat foliage, twigs, and bark.  Up to 80
percent of American mountain-ash stems were browsed by moose in control
plots adjacent to enclosures on Isle Royale.  Fishers, martens,
snowshoe hares, and ruffed grouse also browse American mountain-ash.

The berries of American mountain-ash are eaten by numerous species of
birds and small mammals, including ruffed grouse, ptarmigans,
sharp-tailed grouse, blue grouse, American robins, other thrushes,
waxwings, jays, squirrels, and rodents.


PALATABILITY :
Aldous rates American mountain-ash as one of the most palatable

to 57 percent of their summer diet, depending on availability.
