Narrowleaf Cottonwood is a riparian tree of high-elevation streams in the Rocky Mountains, with narrow, willow-like leaves distinguishing it from other cottonwoods. It forms important gallery forest along mountain streams providing habitat for yellow warblers, willow flycatchers, and beavers. It hybridizes freely with plains cottonwood where their ranges overlap.
