Alternative Silvicultural Systems and Harvesting Techniques for Caribou Habitat

Recognizing that clearcutting leads to habitat loss and increased predation on caribou through apparent competition, the report reviews various silvicultural systems and harvesting techniques, analyzing their potential to maintain old-growth characteristics, limit forage for other ungulates, and minimize access. Through a literature review and expert interviews, the study assesses the applicability of methods like partial harvesting, understory protection, and intensive silviculture in the Alberta context, considering ecological, economic, and practical challenges. The report aims to identify strategies that balance timber harvesting with caribou conservation, acknowledging that site-specific conditions and careful implementation are crucial for the success of any alternative approach. -
Stand Growth and Natural Regeneration Development Following Selection Harvesting of Dry-Belt Douglas-fir - 15 Year Results
This document details a 15-year study examining the effects of partial cut logging, specifically single-tree selection harvesting, on dry-belt Douglas-fir stands in British Columbia.

The research, initiated in 1993, investigated how different levels of residual growing stock and stand structure influenced the growth of remaining trees and the establishment of new seedlings. By remeasuring permanent plots and analyzing overstorey and understorey development, the study aimed to provide long-term data crucial for improving growth and yield models, informing sustainable forest management practices, and understanding the dynamics of these complex forest ecosystems. -
Adjusting Free Growing Criteria for Broadleaves in the Northern Interior of British Columbia

The report achieves this by reviewing existing literature on the silvicultural traits and competitive interactions of both planted conifers and naturally regenerating broadleaf species in the northern interior, alongside the ecological and silvicultural benefits of retaining broadleaves. The study proposes alternative free-to-grow criteria specifically designed to encourage the retention of broadleaf species in the Prince George, Robson Valley, and Mackenzie Timber Supply Areas, aiming for implementation within BCTS Prince George's Forest Stewardship Plan.
