Canada’s northern regions have seen increasingly longer wildfire seasons in recent decades, with the number of days conducive to severe burning rising most steeply in B.C.’s far north, according to a recent study. The findings, published last week in Science, are from a University of British Columbia study led by Weiwei Wang, a research scientist with Natural Resources Canada’s Northern Forestry Centre. Wang’s research used data and modelling in 10 ecozones across Canada to determine the driving forces behind the ecological impact of a wildfire, also known as “burn severity.” …The study examined wildfire severity over a 40-year period, splitting the time frame into two periods, from 1981 to 2000 and from 2001 to 2020. …While elevation and slope were shown to have some influence on fire severity, topography “showed no foremost influence.” The researchers emphasized the “pressing need for proactive strategies to mitigate the increasing threat posed by climate change.”
