Abstract/Description or Keywords | In this paper we review research conducted in small coastal streams on the Queen Charlotte Islands and Vancouver Island. Research on the Queen Charlotte Islands was designed specifically to identify and describe the long-term response of stream channels to increased sediment and debris loadings resulting from both natural processes and forest management practices. The focus of this research is on log-jam characteristics (e.g., origin, function, and longevity) because jams are the major factor controlling the long-term evolution of channel morphology and fish habitats. The streams have a range of natural disturbance histories, with hillslope failure events documented back to the 1820s and impacts from logging that began 40 years ago. Stream Channel Morphology and Recovery Processes D. L. H, S. A. B S. R 78 Research undertaken by the Carnation Creek Fish/Forestry Interactions Program was established to document annual changes in a series of study areas all located within a single watershed. The physical setting of Carnation Creek on Vancouver Island is similar to that of watersheds investigated on the Queen Charlotte Islands (Church, this volume) and enable much finer temporal resolution of channel changes than does the research on the Queen Charlotte Islands. The results from Carnation Creek are used to illustrate a detailed, annual sequence of channel changes that support the longer-term (decades-long) results from the Queen Charlotte Islands. |
