Description

It is a deciduous shrub or small tree, depending on the environment, usually with multiple stems that reach 2 to 7 m in height in dry, cold, high elevation, and other difficult environments, and 10 to 20 m in favorable sites.

Scouler's Willow is the most common upland willow through most of its range. It invades quickly and abundantly after fires and logging. Mineral soil seedbeds are required for seedling establishment (Forest Practices Branch 1997).  At lower latitudes, the species grows in former clearcuts, burned areas, thinned forests, and areas of natural disturbance such as avalanche areas and river flood zones. These are all moist, well-drained to poorly drained sites. Although this willow tolerates drier conditions than most other willows, it does not tolerate xeric conditions.
