Five years after the disastrous wildfire in Fort McMurray, Alta., researchers are warning that the complex role of peatlands, a factor critical to projecting the risk and behaviour of future fires, is missing from the forecasting model.
The Fort McMurray fire burned out of control from May 1 to July 5, 2016, though it continued to smoulder until it was finally declared extinguished Aug. 2, 2017.
Peat deposits – which are prevalent across Canada, especially in Alberta – are complex threats that can complicate and magnify the risk of severe, long-lasting fires and heavy smoke, but they are not yet part of the standard assessment tools that fire managers use.
It’s a critical gap that should be addressed urgently, say the authors of a new paper published today in the International Journal of Wildland Fire, who have completed the first scientific assessment of peatland smouldering fire potential.
