Faced with the challenge of balancing timber extraction with high recreational values and visually sensitive landscapes, this study aims to evaluate different harvesting systems. The study was conducted at Robson Ridge and Pilot Point and compared the productivity, costs, and site disturbance of ground-skidding and cable-yarding methods, highlighting key factors like terrain, machine type, and operational planning that influence the success of these silvicultural approaches in visually sensitive areas. The findings emphasize that meticulous planning, especially concerning road layouts and patch boundaries, is crucial for achieving both economic and environmental objectives in small patch clearcutting. -
Application of a Selection Silvicultural System in the ICHwk1 of the Columbia Forest District
This document details the Revelstoke Community Forest Corporation's implementation of a single-tree selection silvicultural system in a second-growth forest area.

The primary objectives of this alternative harvesting method were to maintain ungulate winter range, cultivate caribou habitat, minimize visual impacts from a nearby highway, and enhance future wood quality, particularly by reducing western white pine mortality. The document outlines the site's characteristics, the planning and prescription process for harvesting, and the challenges and successes of the logging operation, including cost analyses. This document concludes that while initial costs were higher, this approach offers a feasible way to access timber in sensitive areas that would otherwise be off-limits to traditional clearcutting, with an expectation of reduced costs as experience grows. -

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. -
Patch Cutting in Old Growth to Address Concern About Wildlife Habitat and Clearcut Adjacency
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. -
Interior wet fire weather zone
This guidance document outlines best management practices for fuel treatment within British Columbia's Interior-Wet Fire Weather Zone, a region characterized by its productive forests and diverse tree species like western cedar and hemlock. While typ...This guidance document outlines best management practices for fuel treatment within British Columbia's Interior-Wet Fire Weather Zone, a region characterized by its productive forests and diverse tree species like western cedar and hemlock. While typically experiencing higher precipitation and less frequent stand-replacing wildfires, drier subzones are prone to mixed-severity fire regimes. The guide emphasizes managing surface fuels, ladder fuels that allow fire to climb, and crown fuels to reduce the intensity and spread of wildfires, especially given the increased risk from climate change-induced drought and successful fire suppression efforts near communities. The document aims to provide professional guidance for mitigating wildfire threats through strategic fuel management and maintaining forest health. -
Wildfire Facilitates Upslope Advance in a Shade-Intolerant but not a Shade-Tolerant Conifer

Researchers examined post-fire tree regeneration across various fire severities, focusing on the contrasting responses of shade-tolerant and shade-intolerant conifer species. While overall montane species regeneration decreased in burned areas, shade-intolerant Jeffrey pine showed increased success in severely burned plots, aligning with predictions of higher climatic suitability. Conversely, shade-tolerant red fir regeneration declined significantly with higher fire severity, suggesting that the specific regeneration niche of a species, its ideal post-fire conditions, is critical in determining whether fire facilitates or hinders its range expansion. -
Coastal Fire Weather Zone

It details the ecology of this temperate rainforest, noting that while mature stands typically resist widespread fires due to high moisture and closed canopies, disturbed areas and specific drier zones are more prone to fire, especially with the presence of invasive species. The core purpose is to guide fire management through specific interventions, focusing on surface, ladder, and crown fuel reduction to prevent canopy fires, alongside recommendations for forest health mitigation to prevent pest outbreaks after treatment. The document also references established Canadian Forest Fire Behaviour Prediction System fuel types to characterize fire risk and includes practical examples of post-treatment characteristics from various locations. -

It explains that these standards are modifications of existing reforestation guidelines, tailored to achieve specific fire management objectives, such as reducing crown fire potential and enhancing fire suppression effectiveness, particularly near communities and high-value infrastructure. The document details considerations for developing these standards, including species selection based on fire resilience, stand density management to influence fire behavior, and structural characteristics like canopy base height. It provides a framework and examples for forest professionals to create stocking standards that balance timber production with proactive wildfire management at both local and landscape levels. -
Influences of Clearcut Harvesting and Fertilization on Structure and Function of the Soil Food Web in ICH Forests of Southern Interior British Columbia

The first study compared clearcut harvested areas to adjacent forests, finding that clearcutting generally reduced key indicators of soil food web activity and nitrogen cycling. The second study examined the effects of broadcast fertilization on clearcuts, revealing it boosted nitrogen availability but also increased the potential for nitrogen loss through leaching and denitrification. This research aims to inform foresters and managers about how harvesting and fertilization influence soil ecosystems, suggesting ways to mitigate negative impacts and sustain forest productivity.
