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 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.
