Fire deficit increases wildfire risk for many communities in the Canadian boreal forest

M. Parisien, Q. E. Barber, et al.

Explore how decades of fire suppression in Canada's boreal forest may be backfiring, leading to increased wildfire risks near communities. This research, conducted by Marc-André Parisien and his colleagues, uncovers alarming trends showing a significant fire deficit in many areas.

Abstract
This study investigates whether decades of aggressive fire suppression in Canada's boreal forest has reduced the proportion of recently burned forests (RBF) near communities, thereby increasing wildfire risk. Analysis of 160 communities reveals a fire deficit (lack of RBF) in 54.4%, with 74.4% surrounded by a low proportion of RBF (≤10%). This suggests that suppression policies are increasing flammability in the wildland-urban interface.
