Alpine tundra is a type of natural region or biome that does not contain trees because it is at high elevation, with an associated harsh climate. As the latitude of a location approaches the poles, the threshold elevation for alpine tundra gets lower until it reaches sea level, and alpine tundra merges with polar tundra .
In physical geography, a tundra (/ ˈ t ʌ n d r ə, ˈ t ʊ n-/) is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. There are three regions and associated types of tundra: Arctic, [2] Alpine, [2] and Antarctic. [3] Tundra vegetation is composed of dwarf shrubs, sedges, grasses, mosses, and ...
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 ...

Elevations of the ecoregion range from sea level (on the western coast) to 600 m in the valleys, to peaks over 4,000 m. 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.

The maximum elevation is 1,633 metres (5,358 ft). The ecoregion to the north on Baffin Island is the Davis Highlands tundra, which receives more than twice as much precipitation (400-600 mm/year). [6] The terrain varies across the ecoregion. The north and west is mountainous and heavily covered in ice.
