Since 2000, the BC Ministry of Environment has developed a substantial body of science on landslides and forestry operations in coastal British Columbia. Recently, under the Forest and Range Practices Act, there has been a shift in liability from government to licensed professionals. This shift has increased the need to understand, and remain current with, relevant information on forest management practices that may cause landslides.

Recognizing that there are many barriers to accessing new knowledge, this workshop attempts to synthesize in a single day the new volume of landslide information available for Vancouver Island. Drawing mainly from published and submitted scientific papers, the emphasis of the workshop is on understanding and working with regional information to improve on-the-ground practices and reduce landslide risk.

Workshop topics will be illustrated with recent (typically 2005) case studies from across Vancouver Island, and the many practical tools (e.g., maps, data and developing models) available to land managers, forest and geoscience professionals will also be discussed.
