The Farwell Canyon project was established within two Douglas-fir (Pseudotsuga menziesii) stands in the Very Dry Mild Interior Douglas-fir (IDFxm) biogeoclimatic subzone in the Cariboo Region, British Columbia in 2001. The project goals were to improve forage for wildlife and livestock (i.e., increase vascular plant cover), improve the growth of the residual stand by reducing inter-tree competition, shift the plant community composition to one that is more typical of open forest condition, and improve the resiliency of the stand to catastrophic fire. From a timber management perspective, the goal was to increase individual tree growth by logging and thinning while maintaining overall stand-level growth. To achieve these goals, treatment combinations of "modified" logging, pre-commercial thinning, and burning were applied to return the forest to a more open condition that is typical of Douglas-fir forest adjacent to grassland in the IDFxm. This report describes effects of the treatments on the overstorey tree growth and the changes in stand structure over the 10-14 years since treatment.
