The broad objective of this research is to determine the influence of forest management practices on channel morphology by channel type and biogeoclimatic zone. The results are used to assess whether more rigorous management practices have improved channel and riparian conditions and provide a means of accurately extending the results of existing coastal research to all regions of the province. The research objectives of this study are to evaluate the supply rates of woody debris to the stream system and determine the functional role of woody debris by stream type. This includes an evaluation of the role of log jams in creating and modifying riparian zones, a comparison of processes across biogeoclimatic zone, and an assessment of the influence of management practice on channel conditions. The operational objectives are to summarize the research results into guidelines aimed at ensuring the functional integrity of woody debris on managed forest lands. This includes providing operational staff with woody debris management strategies that are regionally and locally relevant (e.g., aid streamside management decisions and road layout in the vicinity of a watercourse), and to assist in the optimization of timber supplies without compromising the integrity of stream environments. The results will be used to develop regionally based "best riparian management practices" for all streams sizes considered by the FPC, and to develop assessment tools that indicate channel and riparian conditions. The results will form a critical component of the review, revision, and scientific justification of the aforementioned FPC guidebooks, as methods are adapted for the new results-based FPC.
