  • Northern Canada: High-latitude Arctic region with permafrost and tundra vegetation.
  • Northern Mexico: Arid and semi-arid desert biomes.
  • Eastern United States: Deciduous forests and coastal plains.

Northern Canada is the only region listed that lies in the high Arctic latitudes where the tundra biome is found.
