Abstract

Fifteen ecozones make up terrestrial Canada, and five make up the marine waters bordering Canada. Canada’s 15 terrestrial ecozones can be subdivided into 53 ecoprovinces, which can be further broken into 194 ecoregions. Ecozones are useful for general national reporting and for placing Canada’s ecosystem diversity in a North American or global context. Ecoprovinces are useful units at an intermediate scale for national and regional planning and reporting purposes. Ecoregions are a useful ecosystem scale for national, provincial, and regional planning and reporting purposes. Regardless of the level in the hierarchy, each unit is distinguished from others by its unique mosaic of plants, wildlife, climate, landforms, and human activities.
