St. Mary River Single Tree Selection Study in the Rocky Mountain Trench

This extension note documents a long-term research project in British Columbia designed to test the operational feasibility of single tree selection within mixed conifer forests. By comparing different levels of basal area retention, researchers are investigating how various thinning intensities influence timber growth, natural regeneration, and understorey light levels. Beyond wood production, the study evaluates how these harvesting methods impact ungulate winter range by measuring snow interception and forage availability for local wildlife. Thsi document serves as a practical model for managing complex, uneven-aged stands, particularly in areas where foresters must balance timber salvage with long-term ecological health.
