This paper investigates the effectiveness of various fuel treatments in mitigating wildfire behavior in British Columbia's seasonally dry forests, a region increasingly vulnerable to extreme fires. Through field measurements and fire behavior modeling, the study assessed how different combinations of thinning, pruning, and residue fuel management impact the potential for crown fires and tree mortality. Key findings suggest that high-intensity thinning is more effective at reducing both passive and active crown fire potential and tree mortality compared to low-intensity thinning, while pruning after thinning offered little additional benefit. The study also highlights that chipping or pile burning residue fuel can reduce crown fire risk, but cautions that chipping may lead to delayed tree mortality not captured by current models, indicating a need for further research on its long-term effects.

This document focuses on fire risk reduction in the Coastal Douglas Fir biogeoclimatic zone and synthesizes expertise from a collaborative community to address the escalating threat of wildfires. It highlights the unique challenges within the CDF, particularly the high concentration of human settlements integrated with forests and the prevalence of degraded, homogenous forest stands resulting from historical logging and fire suppression. The document emphasizes the critical need for ecologically-informed active forest management to restore biodiversity and enhance climate resilience, moving away from a zero-fire model. It explores current initiatives, identifies significant inter-jurisdictional complexities and funding gaps, especially concerning privately held lands, and advocates for multi-scale collaboration and the reintroduction of Indigenous land management practices to achieve long-term wildfire mitigation and ecological integrity.

This document explores the increasingly severe wildland fire situation in B. C. , driven by climate change and accumulated forest fuels, with an emphasis on the urgent need for a whole-of-government provincial landscape resilience strategy. It is structured to detail the current wildfire context, analyze the significant social and ecological impacts of catastrophic wildfire, and examine the current governmental and non-governmental responses to wildfire governance in the province, including the critical role of First Nations and local governments. Ultimately, the primer The document calls for a fundamental shift toward proactive prevention and mitigation measures, highlighting the need to vastly expand fuel management efforts and adopt a comprehensive, collaborative approach to build lasting social-ecological resilience across B. C.

This webinar argues that managing the escalating crisis of high-severity Canadian wildfires requires a move beyond traditional fire suppression toward proactive fuel management. The key is to apply a strategic risk framework that prioritizes efforts based on both fire probability and the immense consequence to critical values at risk, such as vital infrastructure, vulnerable communities, and watersheds. Effective mitigation must combine mandated land-use regulations, such as strict FireSmart building standards, with a significant increase in landscape-level fuel treatments, including prescribed burning. The webinar discusses that achieving long-term success necessitates a fundamental reworking of the existing forest management framework in British Columbia to adequately integrate fire resilience and prevention.

This document establishes a consistent provincial approach for fuel management planning in British Columbia. The primary purpose of this document is to direct forest professionals in developing Wildfire Risk Reduction Plans, which strategically identify and prioritize areas for fuel management projects on Provincial Crown land adjacent to communities. The plan outlines a phased WRR Plan Development Process, moving from data collection and risk analysis to the delineation of planning units, such as Wildfire Risk Reduction Units, and the smallest operational-scale Fuel Management Units, with an emphasis on total-chance planning to ensure community resiliency by reducing wildfire intensity and increasing suppression opportunities. The successful execution of a WRR Plan requires extensive collaboration and coordination among various stakeholders, including the BC Wildfire Service, land managers, and Indigenous Nations.

This webinar presents results from a simulation study of north-central New Mexico that investigated the relative effectiveness of a variety of fuel treatment strategies and the tradeoffs of implementing fuels programs with competing management goals.

This paper investigates the practicality of current wildfire fuel reduction goals in north-central British Columbia by examining mechanical raking treatments within the Burns Lake Community Forest. The study assessed if these treatments achieved the targeted fuel load of 1-5 tonnes per hectare in areas deemed high risk for wildfire. Their findings suggest that meeting these targets using current methods is challenging and potentially unsustainable, highlighting the need for a standardized fuel measurement methodology and more adaptable fuel load targets that consider ecological and operational factors. The research advocates for a more feasible and scientifically sound approach to wildfire risk reduction in the region, emphasizing the importance of consistent data collection for future comparisons and improved practices.

This document provides guidance on harvesting and thinning treatments within Wildland-Urban Interface areas, specifically focusing on reducing wildfire risk in British Columbia. It details a multi-step planning process for Community Wildfire Protection Plans, emphasizing the analysis of land features, existing values like public safety and wildlife habitat, and long-term visions for a fire-resilient forest dominated by Douglas-fir. The report also presents case studies illustrating various fuel reduction methods and their associated costs, alongside operational considerations and responses from professionals regarding logging systems, fuel management, and funding challenges. This document delves into fire behavior modeling to inform best practices for achieving target fuel loadings and canopy base heights, while also highlighting policy conflicts that hinder cost-efficient implementation of these crucial wildfire mitigation strategies.

This paper reviews the effectiveness of stand-level fuel reduction treatments in Canadian boreal conifer forests, specifically focusing on black spruce, jack pine, and lodgepole pine. These treatments, which involve thinning trees, pruning lower branches, and removing understory vegetation, aim to mitigate the risk of fast-spreading, high-intensity crown fires that are naturally prevalent in these ecosystems. While these fuel treatments generally reduce modeled and observed fire behavior under low to moderate fire weather, evidence suggests they become ineffective under very high or extreme fire conditions, especially when combined with high surface fuel loads and the relatively short stature of boreal conifers. The authors highlight the need for further research into managing surface fuel loads, exploring alternative fuel configurations, and integrating these treatments with broader fire suppression strategies.

This webinar examines how legal objectives for mule deer winter range and old growth management affect the Stswecem'c Xget'tem First Nation's ability to reduce wildfire risk, adapt to climate change, and restore ecocultural values in their south-central BC forests. Despite the impacts of settler-colonial policies, SXFN has long stewarded their territory using fire. In partnership with the University of British Columbia, they assessed crown fire risk, fuel loads, and potential treatments, highlighting both current stewardship efforts and the importance of Indigenous sovereignty in land management.

This document outlines how to integrate wildfire risk reduction into forest regeneration practices. 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.
