Relations between tree-ring widths, climate, and annual area burned in the boreal forest of Alberta
Ring-width chronologies from three white spruce (Piceaglauca (Moench) Voss) and two jack pine (Pinusbanksiana Lamb.) sites in the boreal forest of northern Alberta were constructed to determine whether they could provide proxy records of monthly weather, summer fire weather, and the annual area burn...
