Description: Abstract - Landslides related to clearcut logging are a significant source of erosion in the mountains of northwestern California. Forest managers, therefore, frequently must include assessments of landslide risk in their land-use plans. A quantitative method is needed to predict such risk over large areas of rugged mountainous terrain. From air photographs, data were collected of conditions associated with a sample of logging-related slides and randomly located stable sites. Discriminant analyses were used to develop an equation that distinguishes the two types of sites-slide and non-slide-with 81 percent accuracy. The equation can be used to provide an assessment of risk for undisturbed terrain. Results showed that post-logging failure is most likely to occur near actively scouring streams, just below major convex breaks of slope and within drainage depressions.
