The biodiversity of tundra is low: 1,700 species of vascular plants and only 48 species of land mammals can be found, although millions of birds migrate there each year for the marshes. [9] There are also a few fish species. There are few species with large populations.
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 ...

A further 6% of the land, supports herbaceous cover. [5] In the north, only the hardiest cold-tolerant vascular plants can survive, such as sedge ( Carex ) and cotton grass ( Eriophorum ). In a few low-lying, protected areas there can be small stands of Arctic willow ( Salix arctica ), Dryas species, and low-growing purple saxifrage ( Saxifraga ...
A large amount of the land in the north polar region is part of Earth's tundra biome. South of the Arctic tundra, where temperatures are a little less cold, are the vast forests of conifer trees of the taiga biome. North of the Arctic tundra are polar bears and the unique marine life of the Arctic Ocean. [2]
Geographical locations where the tundra biome is found. Tundra is found north of 70° N latitude in North America, Eurasia and Greenland. It can be found at lower latitudes at high elevations as well. [42] The average temperature is −34 °C (−29 °F); during the summer it is less than 10 °C (50 °F).
Ice features such as ice wedges and pingo mounds of soil and ice can be found. This coast has an arctic climate warm enough to allow plant growth in late-June, July and August only, and even then frosts may occur. On the whole this is a damper, wetter area than the Low Arctic tundra ecoregion that continues along the coast west of here to ...
These rocky islands support a variety of plant life, such as tussock grasses, that has adapted to the snowy and icy conditions.There are a number of endemic plant species including Poa cookii grass and the Kerguelen cabbage (Pringlea antiscorbutica), historically a source of vitamin C for sailors, is found on all the islands, not only the Kerguelens.
