Notes: The area damaged by insects is a sum of reported moderate to severe defoliation or damage by insect type and province and may include duplication since forest areas may be damaged by more than one type of insect. Other insects includes jack pine budworm, hemlock looper, gypsy moth, blackheaded budworm, balsam fir sawfly, swaine jack pine sawfly, bruce spanworm, western spruce budworm, large aspen tortrix, two-year-cycle spruce budworm, spruce beetle, aspen twoleaf tier and others. Sums may include missing data where provincial-level species data for specific years was unavailable.
