How does CBI define Canadas Boreal?
The Canadian Boreal ecosystem includes seven ecozones defined under the National Ecological Framework for Canada: the Boreal Plains, Boreal Shield, Boreal Cordillera, Taiga Plains, Taiga Shield, Taiga Cordillera and Hudson Plains, with the exception of the southern part of the Boreal Shield ecozone (Algonquin Lake Nipissing ecoregion) due to the predominantly non-Boreal tree species in that area. The Boreal encompasses almost 6 million km2.
