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 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). [7] [8]
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 ]
There are two types of polar climate: ET, or tundra climate; and EF, or ice cap climate. A tundra climate is characterized by having at least one month whose average temperature is above 0 °C (32 °F), while an ice cap climate has no months averaging above 0 °C (32 °F). [2] In a tundra climate, even coniferous trees cannot grow, but other ...
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.
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).
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 ...
