Abstract

The relationship between the monthly area burned by wildfire from May to August in nine Canadian provinces, and the flammability of the forest as measured by the components of the Fire Weather Index, was investigated. In western Canada with the exception of the Yukon and Northwest Territories, explained variance averaged 33%. In the Terriroties and eastern Canada explained variance averaged 12%. The best predictors of area burned were the monthly means and extreme maximum values of the Duff Moisture Code and the Daily Severity Rating.
