This extension note explores the critical role of fire in the dry interior forests of British Columbia, which historically experienced frequent, low-intensity surface fires that maintained ecosystem health and biodiversity. The authors explain how human fire exclusion over the past 60 years has dramatically altered these forests, leading to increased fuel loads, higher tree density, altered species composition, and a greater risk of intense, large-scale crown fires. The documen then outlines four management options for these sites: continued fire suppression, controlled prescribed burns, mechanical fuel reduction, or a combination of these strategies, emphasizing the need to balance ecological, social, and economic considerations. Finally, the document highlights various ongoing research initiatives aimed at understanding fire regimes and developing integrated management solutions for these fire-adapted ecosystems.

This document outlines best management practices for fuel treatment within British Columbia's interior-dry fire weather zone, a region characterized by dry ecosystems like Interior douglas fir, ponderosa pine, and bunchgrass zones. It emphasizes how wildfires significantly influence these forest ecosystems, historically maintaining biodiversity and grasslands through low-intensity burns. The guide details fuel management strategies for surface, ladder, and crown fuels, including thinning, pruning, and species conversion, all aimed at reducing the risk and intensity of high-severity wildfires. Additionally, it provides recommendations for mitigating impacts on forest health from treatments and includes case studies illustrating effective fuel management practices.

This document outlines best management practices for fuel treatment within British Columbia's coastal fire weather zone, encompassing the Coastal Western Hemlock and Coastal Douglas Fir biogeoclimatic zones. 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.

This report outlines a management strategy for mule deer winter ranges in the Cariboo-Chilcotin region of British Columbia, specifically focusing on transition and deep snowpack zones. Developed through years of research and aligned with existing land use plans, the document provides management objectives and strategies for forest harvesting to maintain and restore suitable habitat. Key areas addressed include access planning, stand age structure, tree species composition, opening sizes for harvests, and the spatial layout of openings. It also includes appendices detailing snowpack zones, biodiversity considerations, forest health management, and a history of related research and planning efforts, aiming to guide forest managers and monitor habitat preservation.

This paper investigates how different forest harvesting methods impact both the amount of carbon stored and the variety of plant and tree life. The study compared the effects of clearcutting, varying levels of partial tree retention, and no harvesting across different climatic regions in British Columbia's Douglas-fir forests, ranging from humid to semi-arid. The central finding is that the intensity of harvesting significantly influences carbon storage and biodiversity, but importantly, the magnitude of these effects is strongly linked to the regional climate.

This case study outlines a detailed approach to employing planned burns for ecological benefits. The document details the ecological role of fire in the Okanagan, current fire management practices, and the proposed strategic plan. Key themes include the restoration and maintenance of ecosystem health and biodiversity through mimicking natural fire regimes, while also addressing risk management and collaboration among stakeholders. The plan likely specifies objectives, strategies, and implementation considerations for using prescribed fire as a vital tool in landscape management.
