Armillaria ostoyae, a cause of armillaria root disease, is a normal component of many forest ecosystems in western Canada. The equilibrium between the fungus and its hosts which usually exists in undisturbed forest stands is upset in favour of the fungus by forest management practices that create stumps. Damage caused by the fungus following these management practices is described. Strategies for reducing damage are discussed.
