North America - Tundra Alpine

The term tundra was used originally in northern Russia and then applied to all areas surrounding the Arctic Ocean. Though controversy still exists as to the definition of tundra, land in northern Canada, Greenland and Alaska contain what is classically and unequivocally recognized as tundra environments. The continuous land beyond the taiga tree line that reaches north to the Arctic Ocean and the series of islands that extend between Canada and Greenland is classified into two types of tundra: Low Arctic and High Arctic.
