A map of North America shows various ecological regions, each marked with a distinct color to represent different Level 1 ecological regions.

Extent of the Level I Ecological Regions of North America

Ecological Regions: Level 1 Regions

Arctic Cordillera (Red): Found in the northernmost parts of Canada, specifically the Arctic Archipelago. Tundra (Blue): Covers large portions of northern Canada, including parts of Nunavut and the Northwest Territories, as well as coastal areas of Alaska. Taiga (Purple): Spans across central and northern Canada, covering parts of Quebec, Ontario, Manitoba, Saskatchewan, Alberta, and British Columbia. Hudson Plain (Orange): Located in the northeastern part of Canada, around the Hudson Bay area.
