The Canadian Arctic tundra is a biogeographic designation for Northern Canada's terrain generally lying north of the tree line or boreal forest, [2] [3] [4] that corresponds with the Scandinavian Alpine tundra to the east and the Siberian Arctic tundra to the west inside the circumpolar tundra belt of the Northern Hemisphere.
The adversity of soil and climatic conditions proves to low production levels, as well as little biomass accumulation due to slow rates of nutrient release in cold and wet soils, specifically as a result of limited nitrogen and phosphorus (Nadelhoffer et al. 1996) Additionally, there are low temperatures and strong winds in the tundra causing most vegetation to be dominated by woody plants ...
The ecoregion is a transition zone between the taiga forests to the south, and the treeless arctic tundra to the north. 50% of the territory is herbaceous cover, 18% moss and lichen, 6% shrubs, and about 1% tree cover in protected areas and along river courses. [ 3 ]
The climate of the ecoregion is Tundra climate (Köppen climate classification ET), a local climate in which at least one month has an average temperature high enough to melt snow (0 °C (32 °F)), but no month with an average temperature in excess of 10 °C (50 °F).
Alpine tundra in the North Cascades of Washington, United States. Alpine tundra does not contain trees because the climate and soils at high altitude block tree growth. [26]: 51 The cold climate of the alpine tundra is caused by the low air temperatures, and is similar to polar climate. Alpine tundra is generally better drained than arctic ...
The Baffin coastal tundra is a small ecoregion of the far north of North America, on the central north coast of Baffin Island in the Canadian territory of Nunavut. This is permafrost tundra with an average annual temperature below freezing.

Indeed, Denali (Mount McKinley), the highest peak in North America at 6,100 m, is located here, while the St Elias Mountains reach as high as 6000 m and are some of the highest peaks in Canada. This ecoregion is largely separated from the coast by the Pacific coastal mountain icefields and tundra so the climate is continental. Rainfall varies ...
