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.

Alpine plants occur in a tundra: a type of natural region or biome that does not contain trees. Alpine tundra occurs in mountains worldwide. It transitions to subalpine forests below the tree line; stunted forests occurring at the forest-tundra ecotone are known as Krummholz.
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. [3] Tundra vegetation is composed of dwarf shrubs, sedges, grasses ...
Lichens dominate the tundra as the region's major primary producer. A symbiotic combination of algae and fungi, a lichen is able to survive in the harsh conditions of the tundra (Biodiversity Institute of Ontario et al. 2010). Their unique structure and survivability make lichen a prominent and keystone plant species in the tundra ecosystem.
This region is characterized by two biomes: taiga (or boreal forest) and tundra. [2] While the taiga has a more moderate climate and permits a diversity of both non-vascular and vascular plants, [ 3 ] the tundra has a limited growing season and stressful growing conditions due to intense cold, low precipitation, [ 4 ] and a lack of sunlight ...
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 ...
The Altai alpine meadow and tundra ecoregion (WWF ID: PA1001) is a terrestrial ecoregion covering the higher elevation of the Altai Mountains at the center of the "X" formed by the borders separating Russia, Kazakhstan, China, and Mongolia. The mountain peaks are the farthest north in Central Asia, separating the plains of Siberia to the north ...
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.
