Abstract

Large Woody Debris (LWD) recruiting to streams and rivers from the riparian forest has a major influence on channel structure and fish habitat throughout British Columbia and the Pacific Northwest. Harvest of riparian forest leads to changes in recruitment of LWD with subsequent long-term effects on both channel structure and fish abundance over decades to centuries. At present, long-term effects of current riparian management practices are unknown. The objective of this project is to develop a model linking riparian management (e.g. buffer width) to LWD input rates, small stream channel structure, and abundance of juvenile anadromous cutthroat trout and coho salmon, and is a direct extension of previous forestry-related research in coastal B.C. streams (Rosenfeld and Parkinson 1995, Rosenfeld et al. 2002, Rosenfeld and Boss 2001, Rosenfeld et al. 2000, Rosenfeld 2000). This model will serve as a management tool for coastal B.C. forest planning and should be applicable outside coastal B.C. when appropriate model parameters become available for other regions.
