Unraveling the complexity of mixed severity fire regimes: New insights from three Rocky Mountain ecosystems

View webinar recording.

In this webinar, Dr. Cameron Naficy presents findings from a synthesis of multiple projects conducted in 3 unique mixed-severity ecosystems from the Rocky Mountains of the U.S. and Canada. He briefly reviews a new reconstruction method his research group developed that combines extensive dendroecological plot networks and detailed forest structure mapping from high-resolution historical aerial imagery. Using these data, he describes the spatial and temporal patterns of fire frequency and severity for each study ecosystem, the fire-mediated stand dynamics and vegetation conditions that characterized each ecosystem, and some novel resilience mechanisms and ecological surprises associated with the mixed-severity fire regime model. This project demonstrates how historical data can be used to move beyond simple summaries of historical fire regime attributes and landscape condition by using historical data to reveal fundamental fire regime processes, drivers, and ecological outcomes.
