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 tundra, [ 2 ] alpine tundra , [ 2 ] and Antarctic tundra.
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 ...

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).
The Bounty Islands are small granite rocks (with a maximum height of 88 m or 289 ft), while the small Antipodes Islands group (maximum height 366 m), the largest group the Auckland Islands (705 m or 2,313 ft) and Campbell Island (569 m or 1,867 ft) are volcanic in origin. Macquarie Island (433 m or 1,421 ft) is the furthest south and the coldest.
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]
The Kola Peninsula tundra ecoregion (WWF ID: PA1106) is an ecoregion that covers the northeastern half of the Kola Peninsula, along the coast of the White Sea, a marginal sea of the Arctic Ocean. The maritime effects of the White Sea create a milder climate than would be expected for a region of this latitude.
