During 1971-75, bark beetles continued as the major cause of tree mortality in British Columbia. The total volume of timber killed decreased markedly, particularly in spruce-alpine fir stands. However, increased mortality occurred in pine stands throughout the Interior of the Province. Defoliating insects caused tree mortality in localized areas in Kamloops and Vancouver Forest regions.
