Infestation of the spruce beetle have resulted in widespread mortality in the spruce forests of Nova Scotia. An estimated 18% of the merchantable white spruce volume, or 1 584 900 m3, is dead and 9%, or 799 200 m3, is infested with the beetle. Only 5% of the red spruce stands examined were infested with the beetle. Attack was more common in white spruce >22 cm diameter than in small trees.
