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 ...
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 ...

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 Torngat Mountains are the southernmost range of the Arctic Cordillera, a chain of mountain ranges that reach 2,500 km to the northern point of Ellesmere Island. The Torngat Mountains form a peninsula between Ungava Bay on the west and the Atlantic Ocean on the east. The ecoregion is only 100 km wide, and 300 km north to south.
The Interior Yukon-Alaska alpine tundra ecoregion (WWF ID: NA1111) covers alpine, sub-alpine, and boreal forest areas along the cordillera (chain of mountain ranges) of Interior Alaska and south-central Yukon Territory. Geologically, they are the disjunct uplands of the Yukon-Tanana Terrane plus a southern extension of the Brooks Range. The ...
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 ...
From the northwest to the southeast the mountains of this ecoregion are the Ogilvie Mountains, the Wernecke Mountains Group, the Mackenzie Mountains, and the Selwyn Mountains. [ 4 ] The alpine regions of this region is situated between the lower elevation ecoregions - Northwest Territories taiga ecoregion to the north, and the Yukon Interior ...
