The contents of this document have been compiled from material entered on the MASS website, which was created and maintained by the Canadian Forest Service. In September 2011, due to increased web accessibility requirements, NRCan conducted a stringent review of its web content to accommodate a 50% reduction of its overall web presence. As a result, many CFS subsites, including those for MASS, have been archived or adapted for delivery in alternative formats.
The Montane Alternative Silvicultural Systems (MASS) project was established in 1991 to address rising concerns about the extent of clearcut harvesting and regeneration performance in high-elevation coastal forests. A multi-disciplinary research and operations partnership tested safety, economic viability, and environmental sustainability of small Patch Cuts, Green Tree Retention, and Shelterwood harvesting, and contributed to the acceptance of Variable Retention as a silvicultural system in British Columbia. Longer term studies evaluated impacts on forest dynamics, soils, microclimate, and biodiversity. In 2012, the study site continues to provide opportunity for further study. Scientists from MacMillan Bloedel (now Island Timberlands) and the Canadian Forest Service led others from University of Victoria, University of British Columbia, and the Forest Engineering Research Institute of Canada (now FPInnovations) in research supported by the Canada–BC Forest Resource Development Agreement (FRDAII), Forestry Practices Initiative of Canada’s Green Plan, Forest Renewal BC, and Natural Resources Canada.
