Hail occasionally causes severe damage in forest stands. Near Candle Lake, Saskatchewan, a severe bail storm damaged 70- to 80-year stands including mixed white spruce (Picea glauca (Moench) Voss), aspen (Populus tremuloides Michx.), and jack pine (Pinus banksiana Lamb.); and pure jack pine. Characteristic symptoms seven years after the initial occurrence included: dead trees, particularly jack pine; dead tops; crowns partly dead and conspicuously thin on the side that faced the storm; open and healed wounds all on the same side of the trees, especially on the thin-barked upper parts, all traceable to the annual ring of the same year.
