Mountain pine beetle continued as the most damaging pest in the Nelson Region. Mature lodgepole pine stands in the Flathead River Valley have been devastated and infestations in other areas expanded. Spruce beetle infestations in Engelmann spruce were found at two new locations. Douglas-fir beetle populations remained low. Larch casebearer and larch needle cast injury was widespread. Larch budmoth defoliated western larch in the West Kootenay and the larch sawfly infestation expanded in the Elk River Valley.
