This extension note explores alternatives to conventional clearcutting for timber harvesting in visually sensitive areas of British Columbia, specifically within the Columbia Forest District. The central purpose is to identify silvicultural systems and harvesting methods that reduce visual impact while maintaining timber supply and ecological health. The document details various standard units of harvesting, such as shelterwood and commercial thinning, explaining their application and effects on the landscape, often contrasting them with traditional clearcutting. This document emphasizes the importance of balancing economic viability with aesthetic and environmental considerations when managing forest viewscapes.

This document details a case study on commercial thinning of older forests in British Columbia's Interior Hemlock Subzone, a forestry practice aiming to improve the growth and quality of remaining trees. The study, conducted by the Revelstoke Community Forest Corporation, investigates the operational feasibility and economic viability of this approach on an 85-year-old stand. Key findings highlight that commercial thinning can yield a significant volume of timber, increase the value of future crop trees, and potentially enhance wildlife habitat, though careful planning is needed to manage associated costs and operational challenges. The report concludes by summarizing recommendations for future commercial thinning operations, emphasizing the importance of clearly defined crop tree selection criteria and methods to reduce costs.

This document details a case study on patch cutting in old-growth forests within British Columbia, specifically addressing its impact on wildlife habitat and its use as an alternative to clearcut logging. The study examines a group selection silviculture system aimed at balancing timber extraction with the preservation of wildlife corridors and habitat, particularly for species like caribou and mule deer. Key objectives included creating uneven-aged stands, reducing snow interception, minimizing logging impacts, and maintaining a percentage of the block area as old-growth. The findings suggest that while patch cutting is operationally feasible and offers benefits over conventional clearcutting, it still requires careful planning and management to effectively meet both economic and environmental goals.

This extension note details a case study on patch cutting in old-growth forests in British Columbia. The primary purpose of this research was to investigate alternative silviculture systems, specifically patch cutting, as a method to maintain caribou habitat. The study aimed to assess the impact of this harvesting technique on the abundance and dispersal of arboreal lichen, a critical food source for caribou, while also considering its effects on windthrow and other forest health factors.
