Recent studies show that plant roots or fibers can significantly increase the shear strength of soils by increasing the apparent cohesion of the soil. The author is presently studying this effect on soils by vegetation, mainly by examining the effect of forest clear-cutting on the stability of natural slopes, was found to be affected by trees and vegetation, causing modifications of soil characteristics and soil moisture stress, the author monitored creep rates before and after cutting. The preliminary results of a side-by-side type study in a forested and adjacent cut-over watershed in Oregon suggest that a forested slope creeps at a lower rate than a cut-over one.
