Jasper wildfire complex 2024 : fire behaviour documentation, reconstruction, and analysis. : Fo133-1/433E-PDF

"Following a highly destructive 2024 wildfire in Jasper, Alberta, a study was completed to describe the behaviour and environmental factors associated with this event. On July 22, 2024, lightning ignited multiple fire starts in the upper Athabasca valley in Jasper National Park following a month-long drought. Three ignitions merged as the South Fire and advanced rapidly toward the Jasper townsite. A separate incident closer to the community initially drew most attention and suppression resources. … This report integrates operational interviews and photographs, field measurements, management records, and modelling to reconstruct the sequence and drivers behind this event. Key contributing factors include drought conditions, rapid ignition and acceleration, continuous and mountain pine beetle (MPB)-affected fuels, sustained high intensity, plume-driven behaviour, convection column collapse, and ember transport. The 2024 Jasper Wildfire Complex illustrates the increasing challenge of managing extreme wildland fire events in Canada's evolving fire landscape. By documenting and analyzing this event, this report provides insights into the need for improved understanding and predictive models and to enhance landscape and community resilience to future wildfire threats"--Abstract, page v.
