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.

Polar ecology is the relationship between plants and animals in a polar environment. Polar environments are in the Arctic and Antarctic regions. Arctic regions are in the Northern Hemisphere , and it contains land and the islands that surrounds it.
Instead, bare and sometimes rocky land can only support certain kinds of Arctic vegetation, low-growing plants such as moss, heath (Ericaceae varieties such as crowberry and black bearberry), and lichen. [6] [7] There are two main seasons, winter and summer, in the polar tundra areas.
Nothofagus fusca, New Zealand. Antarctic flora are a distinct community of vascular plants which evolved millions of years ago on the supercontinent of Gondwana.Presently, species of Antarctica flora reside on several now separated areas of the Southern Hemisphere, including southern South America, southernmost Africa, New Zealand, Australia, and New Caledonia.
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 ]
For an island so far north, this number of species constitutes an astonishing variety of plant life. Because of the harsh climate and the short growing season, all the plants are slow growing. They seldom grow higher than 10 cm (4 in) In some areas, especially in warmer valleys, the plants produce carpets of blossoms.
Cassiope tetragona (common names include Arctic bell-heather, white Arctic mountain heather and Arctic white heather) is a plant native to the high Arctic and northern Norway, where it is found widely. Growing to 10–20 cm in height, it is a strongly branched dwarf shrub. The leaves are grooved, evergreen, and scale-like in four rows.
