This study aims to quantify the loss of coarse woody debris habitat due to reservoir construction and identify affected terrestrial vertebrate species. The authors explore management strategies to restore or enhance CWD, defining CWD as woody material greater than 10 cm in diameter lying on the ground, including stumps. The paper provides a framework for understanding and mitigating the ecological consequences of hydroelectric development on forest ecosystems.

This technical report evaluates the effectiveness of selection harvesting as an alternative to clearcutting within the old-growth temperate rainforests of Vancouver Island. By comparing single-tree and group selection methods, the study examines how these systems maintain an uneven-aged stand structure while meeting reforestation requirements on steep, ecologically sensitive terrain. The research highlights significant operational challenges, noting that safety regulations and the complexities of helicopter yarding often require foresters to adapt their initial harvesting prescriptions. This document concludes that while natural regeneration is abundant, the slow growth rates in shaded environments may require adjusted timelines for achieving free-growing status and long-term forest health.

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.
