Bark beetles killed 17,000 lodgepole pines of 5,100 acres (2,040 ha) at 48 locations in the District in 1975. Conifer defoliator populations declined from 1974 levels. Porcupine feeding on lodgepole pines was common throughout the District. Damage induced by weather conditions was evident at three locations and foliage diseases were confined to trembling aspen and spruce.
