Raphael Chavardes describes his project to reconstruct the natural fire history of Jasper National Park. Raphael found evidence of historical fire regimes that included low-, medium-, and high-severity fires, which contradicts the usual assumption that these landscapes were historically driven mainly by high-severity fires.
Importantly, he found that during the 20th century, the number of fires has drastically decreased. He explores climate versus human impacts on fires in the area, and how these changes to the fire regime have affected forest diversity in Jasper National Park.
