Canada's Boreal Forest: One of Earth's Last Great Wilderness Regions
The boreal forest stretches across the northern third of Canada — a vast belt of spruce, fir, and muskeg that stores carbon, sustains wildlife, and defines the ecological identity of the country.

About the Biome
The Northern Third of Canada, Covered in Forest
Spanning from Newfoundland and Labrador to the Yukon and parts of British Columbia, Canada's boreal forest forms the southern fringe of the circumpolar taiga belt. It covers roughly 552 million hectares — approximately 77 percent of Canada's total forest area.
The biome is defined by its cold continental climate, vast peatlands, and species assemblages adapted to fire, permafrost, and long winters. Black spruce, jack pine, trembling aspen, and tamarack dominate much of the canopy, while sphagnum moss carpets the forest floor in wetter zones.
Because of its scale and intact character in many regions, the Canadian boreal carries disproportionate global significance for carbon storage, freshwater retention, and migratory bird habitat.
