Talus Slopes (non-forested)

Non-forested talus slope communities are found in the Appalachian provinces on colluvial talus slopes where they form significant accumulations beneath upslope cliff-lines. Nearly all known examples in Tennessee are small and are positioned on otherwise forested slopes although trees and shrubs may be sparse to absent from the talus itself. Such examples are treated here. They range from densely vegetated communities dominated by coarse herbs such as leafcup (Polymnia canadensis) to sparsely vegetated or non-vegetated communities. When vegetation is sparse to lacking they may support a variety of lichen species. Forested talus slope communities are treated separately under the Forests, Woodlands, and Shrublands section.
