Abstract
Mountain pine beetles devastated pine stands in the Columbia, White and West Kettle River valleys, whereas other species of bark beetles remained at low levels. Larch casebearer moderately damaged larch stands and further expanded its range. False hemlock looper, spruce budworm and black army cutworm outbreaks declined. The tree diseases, Armillaria root rot, globose gall rust and white pine blister rust continued to cause tree mortality and increment loss.
