Forest insect and disease conditions in Alberta, Saskatchewan, Manitoba, and the Northwest Territories are summarized for 1994. Ground and aerial surveys included mapping pest infestations, trapping pests using pheromone-baited traps, conducting field observations for pest collection and identification, measuring damage intensity, and updating of pest distributions and their hosts throughout the study area. Spruce budworm, forest tent caterpillar, large aspen tortrix, aspen leafroller, mountain pine beetle, Douglas-fir beetle, spruce beetle, lodgepole pine dwarf mistletoe, spruce gall midge, satin moth, and Dutch elm disease infestations are discussed. Other pests specifically affecting forests, young stands, aspen forests, and forest nurseries are also discussed. An update of surveys for acid rain symptoms in permanently established ARNEWS (Acid Rain National Early Warning System) plots is also reported. Other noteworthy insects, diseases, and tree damage agents are presented in tabular form. Forecasts of spruce budworm, jack pine budworm, and forest tent caterpillar populations are reported for 1995.
