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 ...
In physical geography, 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 lichens ...
Wildlife includes large colonies of seabirds on the islands and waterbirds and shorebirds in the many wetlands such as the Kuskokwim River delta, one of the largest waterbird nesting areas in the world and home to the world's largest communities of tundra swan, most of the world's emperor goose, and half of the world's black brant (Branta ...
This is a largely unspoilt environment home to large predators, although there is some development associated with tourism, especially at Kantishna near Denali Park, and some mining activity including the abandoned copper mining camp of Kennecott, Alaska in the Wrangell Mountains and coal mining at Nabesna and Healy, Alaska.
Alpine tundra occurs at high enough altitude at any latitude.Portions of montane grasslands and shrublands ecoregions worldwide include alpine tundra. Large regions of alpine tundra occur in the North American Cordillera and parts of the northern Appalachian Mountains in North America, the Alps and Pyrenees of Europe, the Himalaya and Karakoram of Asia, the Andes of South America, the Eastern ...

Iceland is of volcanic origin with the landscape being influenced by water and wind erosion, abrasion and frost action. The Highlands form a plateau some 500 m (1,640 ft) above sea level, lying in the central and southeastern part of the island, and occupy about 40% of the landmass; they consist largely of volcanic deserts interspersed with glaciers.
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.
