Dead and Down Woody Debris Fuel Loads in Canadian Forests

This research compiles and analyzes a national database of dead and down woody debris to improve fire behavior and effects modeling in Canadian forests. The study emphasizes that DWD is a major component of surface fuels, significantly impacting fire intensity, consumption, and the transition to crown fires. By examining various forest types and ecozones, the authors identified key predictive variables such as bioclimatic regime, age, and structural components. This work provides crucial tools for a more accurate understanding of DWD distribution across Canada, enhancing the country's ability to forecast and manage wildfires.
