This research study uses predictive modeling to demonstrate that harvesting intensity and climatic aridity are the primary drivers of future carbon loss in British Columbia's Douglas-fir forests. By simulating forest growth over a fifty-year period, the authors found that clearcutting significantly reduces total ecosystem carbon compared to lower-intensity methods like patch retention, which better preserve aboveground biomass. The data further reveals that forests in arid regions are more vulnerable to carbon depletion than those in humid climates, especially when high-intensity logging is applied. This document advocates for low-intensity harvesting systems and improved forest stewardship as essential strategies to maintain carbon sequestration and mitigate global warming.

This paper investigates how different forest harvesting methods impact both the amount of carbon stored and the variety of plant and tree life. The study compared the effects of clearcutting, varying levels of partial tree retention, and no harvesting across different climatic regions in British Columbia's Douglas-fir forests, ranging from humid to semi-arid. The central finding is that the intensity of harvesting significantly influences carbon storage and biodiversity, but importantly, the magnitude of these effects is strongly linked to the regional climate.

This document details a study using the TASS II growth model to assess how different forest management techniques impact the timber production of lodgepole pine in mixed stands with aspen. Prepared for the Interior Broadleaf Working Group, the report simulates various scenarios involving different densities of aspen and several treatments like brushing at different ages and herbicide application. The core purpose is to provide guidance on choosing the most effective brushing strategies to maximize conifer timber objectives in the Prince George Timber Supply Area, by analyzing the projected growth and yield of lodgepole pine under these varying conditions. The study meticulously examines factors such as site index, height growth, tree survival, and ultimately, the merchantable volume of pine achieved with and without intervention.
