About 80 percent of Canada’s 1 million First Nations and Métis live on reserves and communities in boreal or temperate forests.
7 million hectares (or 12 percent) of forest theoretically available for timber harvest. Although there may be overlap once again between areas burned and logged, it does not factor in insect damage. Because data are not available on fire and insect damage occurring within the 119 million hectares of forest currently managed for timber production, it is difficult to estimate what proportion of these lands are disturbed annually both from logging and from natural events. Such information would provide a more accurate measure of whether current management regimes are sustainable.
