The objectives of our proposed research are to compare the large woody debris (LWD) budgets and channel morphology in managed watersheds with those from similar old growth forests. A comparison of LWD budgets (input, storage, and output) enables critical assessment of the influence of different management strategies in small headwater streams (channel widths <3 m), intermediate (channel widths 3 to 30 m) and large (widths >30 m) sized-streams in different biogeoclimatic zones in British Columbia. Three management scenarios (post-Forest Practices Code (FPC), pre-FPC recent, and pre-FPC old) will be considered. The results will resolve questions such as those dealing with the effectiveness/requirement of buffer strips along small streams, the source of LWD in intermediate streams, and wind-firmness of trees left standing along larger FPC streams (S1, S2, and S3).
