| Abstract/Description or Keywords | Debris flows and other types of landslides are a common occurrence both naturally and following logging in Clayoquot Sound and Barkley Sound. Identifying terrain susceptible to landslides following logging and road building will be critical for ongoing forest management in the Clayoquot Sound/Barkley Sound area. An empirical approach, applied to a representative sample of logged hillslopes within a specific geographical area, is used to quantify the likelihood and frequency of postlogging landslide occurrence. For each map polygon within a sample area, terrain data including slope, slope morphology, surficial material, bedrock type, and the presence or absence of natural and post-logging landslides are recorded. Analysis of the data uses non-parametric univariate or multivariate statistical tests to identify relationships between landslide frequency or likelihood and terrain features. In this report data collected from Clayoquot Sound and Barkley Sound is analyzed and relationships between terrain features and post-logging landslide occurrence are presented. |
