Technical Bulletin No. 0456: Catalog of Landslide Inventories for the Northwest

Landslides are an important source of sediment in both undisturbed and managed steep drainages in the Northwest. Recent regulatory and management issues, including a lawsuit against the Siuslaw National Forest, and proposals for new state forest practice rules have focused attention on landsliding processes, and control opportunities. Most of the information on landslide rates and factors controlling landslides has been obtained from landslide inventories, some of which cover large areas and time periods.
