yellow aspenQuaking aspen (Populus tremuloides) is the most widely distributed native Northern American tree species and is abundant in the Intermountain West. Aspen is found across a range of elevations and in a variety of habitats from sagebrush-steppe to mixed-conifer forests and subalpine meadows. Aspen communities support a large number and diversity of understory and overstory plant species and provide habitat for many birds and small mammals. Aspen dieback and mortality is a concern across the western US. Recent studies can be used to inform aspen restoration and the stabilization of existing populations. Resources listed here provide the background necessary to understand causes of site-specific aspen decline and to inform restoration planning in the Northern Rockies.

This hot topic was developed in partnership with Grand Teton National Park.
