The cool, wet climate of British Columbia?s Central and North Coast and northern Vancouver Island has created extensive forested landscapes with organic and organic-rich soils that have developed on moderate to steep slopes. Landslides in organic soils provide a challenge to forest operations in coastal British Columbia. Often landslides initiate at much lower slope gradients than is typical for shallow landslides; as a result, the hazards associated with organic soils are sometimes not identified. Landslides in organic soils are frequently triggered during road construction and timber harvesting activities, and therefore can pose a significant risk to worker safety. The objectives of this Extension Note are to: ? promote awareness about land slides in organic soils on gentle through moderately steep slopes, provide details on site conditions ? associated with landslides in organic soils, and provide alternative management ? strategies to manage the risk associated with road construction and timber harvesting in areas in which organic landslides could occur.
