Abstract

Abstract - Accelerated erosion in the form of landslides can be an undesirable consequence of clearcut logging on steep slopes. Forest managers need a method of predicting the risk of such erosion. Data collected after logging in a granitic area of northwestern California were used to develop a predictive equation. A linear discriminant function was developed that correctly classified almost 90% of the data. The equation was based on measurements of slope, crown cover, tributary drainage area, and distance from a stream. A procedure was then developed by which the discriminant function can be used to determine the optimum strategy for managing landslide-susceptible terrain
