    Quaking aspen (Populus tremuloides) is the most  widely distributed tree in North America. It is known by many  names: trembling aspen, golden aspen, mountain aspen, popple,  poplar, trembling poplar, and in Spanish, álamo blanco,  and álamo temblón (49). It grows on many soil  types, especially sandy and gravelly slopes, and it is quick to  pioneer disturbed sites where there is bare soil. This  fast-growing tree is short lived and pure stands are gradually  replaced by slower-growing species. The light, soft wood has very  little shrinkage and high grades of aspen are used for lumber and  wooden matches. Most aspen wood goes into pulp and flake-board,  however. Many kinds of wildlife also benefit from this tree.
