This study investigated timber harvesting and mass wasting on the Queen Charlotte Islands. Logging impacts on the frequency and yield of landslides from steep slopes and on the volume of material entering streams were examined for a study area comprised of 27 basins covering 350 km2 between Rennell Sound and Burnaby Island. The influence of logging was assessed by comparing the yield and frequency of landslides calculated for clearcut and road areas to that from forested terrain.
