Inventories of shallow, rapid soil mass movements (debris avalanches) are useful for assessing impacts of forestry practices such as clearcutting and road construction. Analysis of inventory data from steep Pacific Rim forest land indicates a several-fold increase in debris-avalanche erosion from clearcutting relative to the rate in forested areas and even greater increases from roads. Some of the limitations of interpretation of inventory data can be overcome with improved data analysis.
