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.
