Quaking Aspen (Populus tremuloides)

A 35-50 ft., sometimes taller, deciduous tree, quaking aspen is pyramidal when young, usually developing a long trunk and narrow, rounded crown at maturity. Its small, nearly round, shiny leaves have a flattened petiole which allows them to quiver in the slightest breeze. Smooth, whitish-green bark becomes furrowed at the trunk’s base with age. Silvery catkins appear before leaves. Fall color is bright yellow. The names refer to the leaves, which in the slightest breeze tremble on their flattened leafstalks. The soft smooth bark is sometimes marked by bear claws. A pioneer tree after fires and logging and on abandoned fields, it is short-lived and replaced by conifers. Sometimes planted as an ornamental. Principal uses of the wood include pulpwood, boxes, furniture parts, matches, excelsior, and particle-board. The twigs and foliage are browsed by deer, elk, and moose, also by sheep and goats. Beavers, rabbits, and other mammals eat the bark, foliage, and buds, and grouse and quail feed on the winter buds.
