Before the high-intensity Jasper Wildfire Complex of July 2024, Jasper National Park had an abundance of altered fuels – from an extensive mountain pine beetle outbreak, and from the community FireSmart initiatives that had been undertaken for 20 years. We set out to characterize these fuels at a high detail using both field and airborne lidar data. First, the impacts of mountain pine beetle on fuels over a range of severity are investigated. Second, fuel treatment efficacy over two decades was evaluated using field and lidar-derived canopy metrics. This research provides critical insight into the variability within both managed and disturbed fuels over time, and gives an in depth description of the fuels that burned in the JAPC-010-Jasper Complex fires this summer. Tristan Skretting is a recent MSc graduate of University of Lethbridge under Dr. Laura Chasmer, studying the wildland fuels in the Athabasca Valley of Jasper National Park, and successfully defended her thesis in July. She is happy to be joining Raphael Chavardès at the Canadian Forest Service for the spring to characterize fuels in the Acadian-Wabanaki forests of New Brunswick and Nova Scotia. Her overall research objective is to examine the relationships between changing fuels and wildfire potential in a warming climate. Moving forward, she hopes to be involved in proactive community protection, wildfire risk evaluation and boosting ecosystem resilience.
