Note: Data include those areas where there is tree mortality and moderate to severe defoliation. Defoliation does not always imply mortality. Defoliation data is collected on an insect-species basis. Because any forested area can be defoliated by more than one insect, there may be considerable overlap in the reported figures. The area within which there is moderate to severe defoliation can also include roads, cultivated areas, small lakes and burned areas.

Note: National data include all burned areas within Canada’s forests. Provincial data do not include fires within national parks. In 2015, 84 fires burned 282,131 hectares in national parks across Canada. Some of these fires were controlled or prescribed burning for ecological restoration purposes.
