The authors explore how different harvesting methods in a specific forest type could meet sustainability targets, encompassing biodiversity, visual quality, old-growth recruitment, and timber production over a 100-year rotation. By modeling several scenarios and comparing their outputs, the study aims to familiarize readers with the PrognosisBC tool and demonstrate its utility in assessing trade-offs and informing complex forest management decisions, while also acknowledging the model's limitations and the crucial role of professional judgment. -
Harvesting on Mule Deer Winter Range under General Wildlife Measures for Shallow Moderate Snowpack Zones Approach and Lessons Learned following a Second Harvest Entry after 30 Year
This report details a second timber harvest entry conducted on a mule deer winter range in British Columbia, thirty years after the initial logging. The study examines the application of General Wildlife Measures for shallow and moderate snowpack z...This report details a second timber harvest entry conducted on a mule deer winter range in British Columbia, thirty years after the initial logging. The study examines the application of General Wildlife Measures for shallow and moderate snowpack zones, focusing on a clumpy single-tree selection silvicultural system designed to balance timber harvesting with maintaining and enhancing mule deer habitat. Key aspects explored include the planning and operational implementation of this approach, including the creation of small canopy gaps and thinning from below, along with the lessons learned regarding ecological impacts, adherence to regulations, and operational feasibility. The report serves to document this long-term research project's progression and inform future management practices on similar winter ranges. -
Can Thinning and Fertilizing Young Lodgepole Pine Mitigate Future Timber Supply Challenges
This extension note reports on a 14-year study investigating how thinning young lodgepole pine stands to different densities and repeatedly fertilizing them with multiple nutrients affects their growth. The central question explored is whether these ...This extension note reports on a 14-year study investigating how thinning young lodgepole pine stands to different densities and repeatedly fertilizing them with multiple nutrients affects their growth. The central question explored is whether these silvicultural practices can accelerate stand development enough to help offset future timber supply shortages anticipated due to the mountain pine beetle epidemic. The research measured the impact of these treatments on tree size and overall stand volume, aiming to determine optimal strategies for mitigating timber supply challenges in the interior of British Columbia.
