The Summer Tundra:
The Arctic is dominated by two ecozones, the Boreal Forest, and further north, the Tundra.
The treeless rocky tundra with its permanently frozen ground is the ecosystem most closely associated with the far north. It covers over a quarter of Canada and over three-quarters of Alaska.
Because of its harsh climate and the presence of permafrost, the tundra is home to many unique plants and animals with some remarkable adaptations. |
