Arctic vegetation is largely controlled by the mean temperature in July, the warmest month. Arctic vegetation occurs in the tundra climate, where trees cannot grow.Tundra climate has two boundaries: the snow line, where permanent year-round snow and ice are on the ground, and the tree line, where the climate becomes warm enough for trees to grow.

Svalbard has permafrost and tundra, with both low, middle and high Arctic vegetation.There have been found 165 species of plants on the archipelago. [3] Only those areas which defrost in the summer have vegetations, which accounts for about 10% of the archipelago. [11]
Arctic ecology is the scientific study of the relationships between biotic and abiotic factors in the arctic, the region north of the Arctic Circle (66° 33’N). [1] This region is characterized by two biomes: taiga (or boreal forest ) and tundra . [ 2 ]
The Kalaallit Nunaat high arctic tundra ecoregion covers the coastal areas of northern including the upper half of the west coast and the upper one-third of the east coast. [1] Greenland (called Kalaallit Nunaat in the Greenlandic language). Areas inland of this strip of land are either covered in ice or bare rock.
The underlying soil of this damp Arctic coast is thick, solid permafrost, covered in summer with thermokarst "thaw lakes" of melted ice. 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.
Frost action processes have a strong effect on the soil and vegetation of arctic-alpine regions. [5] Tropical alpine regions are subject to these conditions as well, but they seldom happen. Because northern alpine areas cover a massive area it can be difficult to generalize the characteristics that define the ecology. [ 6 ]
Eriophorum callitrix, commonly known as Arctic cotton, Arctic cottongrass, suputi, or pualunnguat in Inuktitut, is a perennial Arctic plant in the sedge family, Cyperaceae. It is one of the most widespread flowering plants in the northern hemisphere and tundra regions. Upon every stem grows a single round, white and wooly fruit.
