Description :
The aim of this study was to investigate biomechanical effects of trees beyond treethrow, particularly displacement by tree growth and the potential for transport of regolith material into stump holes. Specifically, they sought to document the extent of surface displacement (as indicated by rock fragments) and formation of stump rot depressions; to estimate the importance of these biomechanical effects relative to uprooting; and to identify common patterns of soil and regolith development associated with individual trees. Rocky soils in the Ouachita Mountains in Arkansas were studied.
