Report: Fire Regime Dynamics of the Southwestern Alberta Foothills

Report: Fire Regime Dynamics of the Southwestern Alberta Foothills

This final report by the Fire Regime Team describes their landscape-scale assessment of fire frequency, severity and age structures for six study areas distributed throughout the montane and lower subalpine zone of the Foothills using dendroecological methods. They describe and contrast the fire regimes and ecological outcomes for the lodgepole pine and Douglas-fir zones of their study sites and implications of these results.

Webinar: Altered fire regimes and reduced montane forest diversity

Webinar: Altered fire regimes and reduced montane forest diversity

This presentation from the Webinar Wednesdays series of the Healthy Landscapes Program (fRI Research) explores the reconstructed fire history of sites within Jasper National Park. Raphael found evidence of mixed-severity fire regimes, and explores how altering these regimes has affected the landscape.

Altered mixed-severity fire regime has homogenised montane forests of Jasper National Park

Altered mixed-severity fire regime has homogenised montane forests of Jasper National Park

Fire suppression has altered the forests of Jasper National Park. Historically, the sites we studied experienced a mix of high-severity fires and low-to-moderate severity fires. With no fires since 1905, these forests have aged together and homogenised, making them more susceptible to high-severity fire. Prescribed burning is recommended to promote forest resilience.

Evidence of mixed-severity fires in the foothills of the Rocky Mountains

Evidence of mixed-severity fires in the foothills of the Rocky Mountains

Industrial disturbances like harvesting are increasingly trying to mimic wildfire, but first we need to understand how wildfire has historically affected forests. This study shows that the foothills of the Rocky Mountains in Alberta historically experienced high-severity, stand replacing fires, but also low-to-moderate-severity fires that resulted in stands with complex structure.
