This study investigates alternative forestry practices to mitigate the negative impacts of conventional clearcutting on 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.

This case study the practical and economic implications of implementing ecosystem-based management principles in a coastal British Columbia old-growth forest. The study specifically examines a harvesting operation that incorporated retaining tree patches and individual trees to promote biodiversity and ecological function, while assessing the productivity and costs associated with the applied harvesting systems and equipment. The report aims to provide insights into the operational challenges and potential efficiencies of adopting this new paradigm of forest management compared to traditional clearcutting practices.

This case study investigates the economic and operational feasibility of implementing variable retention harvesting in coastal British Columbia. It details a specific trial on northern Vancouver Island, comparing a clearcut and a dispersed retention compartment within the same cutblock, analyzing the productivity and costs associated with different harvesting systems and equipment. The study aims to provide information on the practical challenges of adopting new forest management principles focused on sustaining ecological values alongside economic viability, ultimately contributing to the refinement of these techniques through adaptive management.
