    Description

    No other tree in the Rocky Mountain region is more highly valued for its amenities than aspen (Populus tremuloides). In Colorado, New Mexico, Arizona, and southern Utah, aspen covers entire mountain slopes and plateaus, sometimes forming the landscape matrix in which other cover types occur as patches. Northward aspen occurs in patches (figure 1), forming small groves that can be thought of as a keystone cover type - one that has more significant effects on species diversity and ecological processes than would be expected considering the comparatively small amount of land area that it occupies.
