Terrain within the Skidegate Plateau of the Queen Charlotte Islands was studied to determine if landslide frequencies could be correlated to specific landscape attributes or combinations of attributes. The analysis indicates that roadfill landslide frequency is associated with slope angle, natural landslide presence, slope position, and slope morphology, whereas clearcut landslide frequency is related to these factors as well as to surficial material, bedrock formation, horizontal slope curvature, and soil type. Combinations of these variables are used to develop landslide risk classifications.
