Some Arctic plants grow close to the ground as cushion plants, which keep the plants close to the warm soil and shield the tender central growing shoot. Arctic plants limit their height to be below the snow level. Plants that protrude above the snow are subject to strong winds, blowing snow, and being eaten by caribou, muskox, or ptarmigan.

An Arctic–alpine taxon is one whose natural distribution includes the Arctic and more southerly mountain ranges, particularly the Alps. [1] The presence of identical or similar taxa in both the tundra of the far north, and high mountain ranges much further south is testament to the similar environmental conditions found in the two locations.
The flora of the alpine tundra is characterized by plants that grow close to the ground, including perennial grasses, sedges, forbs, cushion plants, mosses, and lichens. [28] The flora is adapted to the harsh conditions of the alpine environment, which include low temperatures, dryness, ultraviolet radiation, and a short growing season.
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 ]
Alpine plants can exist at very high elevations, from 300 to 6,000 metres (1,000 to 20,000 ft), depending on location. [8] [9] For example, there is a moss that grows at 6,480 m (21,260 ft) on Mount Everest. [9] Arenaria bryophylla is the highest flowering plant in the world, occurring as high as 6,180 m (20,280 ft).

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.
Papaver radicatum (arctic poppy), a flowering plant of the Arctic tundra follows the sun around the sky during the 24-hour daylight of summer north of the Arctic Circle. Changing climate conditions are amplified in polar regions and northern high-latitude areas are projected to warm at twice the rate of the global average. [1]
