Forest management in interior British Columbia: moving beyond equivalent cut area
Alila, Younes
Although the relation between Equivalent Cut Area (ECA) and hydro-geomorphology at the watershed scale is not well understood ECA continues to be used to constrain forest management in BC. Until this relation is understood in a quantitative manner we may be unduly restricting forest development at great cost to the industry. The urgency to understand how ECA affects hydro-geomorphology has increased with recent pine beetle epidemics and wildfires that are creating disturbances in watersheds equivalent to 100% ECA. This project is an interdisciplinary multi-stakeholder initiative to quantify the relationships between ECA and watershed hydro-geomorphology. This study uses an original and innovative ecosystem approach that supplements field based results with long-term numerical modeling to address the linkages between changes in upland hydrology and the effects on channel condition/stability. Hydro-geomorphic analysis of Cotton Creek together with several other experimental watersheds will be combined to provide forest managers and professionals with guidelines, tools and models to link in an original way watershed hydro-geomorphology with forest management and to apply these results to watersheds with a wide range of physiographic, climatic, and hydro-geomorphic characteristics in BC?s southern interior.
