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 Tundra of North America is a Level I ecoregion of North America designated by the Commission for Environmental Cooperation (CEC) in its North American Environmental Atlas. One of the planet's most recent biomes, a result of the last ice age only 10,000 years ago, the tundra contains unique flora and fauna formed during the last glaciation ...
Arctic ecology. A sunset in the arctic region. Arctic ecology is the scientific study of the relationships between biotic and abiotic factors in the arctic, the region north of the Arctic Circle (66° 33’N). [1] This region is characterized by two biomes: taiga (or boreal forest) and tundra. [2] While the taiga has a more moderate climate and ...
The Canadian High Arctic Tundra ecoregion encompasses most of the northern Arctic archipelago, from much of Baffin Island, Somerset Island, and Prince of Wales Island in the south, through all islands northward to the most northern island in Canada, Ellesmere Island. [3] Much of the northern islands are covered in ice, and the climate is very ...
Mount Elbert rises through multiple biotic zones, with alpine tundra at its peak.. The Rocky Mountains range in latitude between the Liard River in British Columbia (at 59° N) and the Rio Grande in New Mexico (at 35° N), and in height up to the highest peak, Mount Elbert at 14,440 feet (4,400 m), taking in great valleys such as the Rocky Mountain Trench and San Luis Valley.
The Canadian boreal forest is a very large bio-region that extends in length from the Yukon-Alaska border right across the country to Newfoundland and Labrador. It is over 1,000 kilometres (620 mi) in width (north to south) separating the arctic tundra region from the various landscapes of southern Canada. The taiga growth (as defined in North ...
Canada's 15 terrestrial ecozones are further subdivided into 53 ecoprovinces, 194 ecoregions, and 1,027 ecodistricts. [13]Canada is characterized by a wide range of both meteorologic and geological regions that are divided into fifteen terrestrial and five marine ecozones, [14] such as the forests of British Columbia and Central Canada, the prairies of Western Canada, the tundra of Northern ...
