Alpine tundra in the North Cascades of Washington, United States. Alpine tundra does not contain trees because the climate and soils at high altitude block tree growth. [26]: 51 The cold climate of the alpine tundra is caused by the low air temperatures, and is similar to polar climate. Alpine tundra is generally better drained than arctic ...
Both plant species and animal species have become endangered. The Aleutian shield fern is a plant species that have been endangered due to caribou tramping and grazing, slumping from growing substrate, and human foot traffic. [9] Animal species that are endangered in the tundra include the Arctic fox, caribou, and polar bears.
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.
Alpine tundra is a type of natural region or biome that does not contain trees because it is at high elevation, with an associated harsh climate. As the latitude of a location approaches the poles, the threshold elevation for alpine tundra gets lower until it reaches sea level, and alpine tundra merges with polar tundra .
Alpine plants are not limited to higher elevations. However, high-elevation areas have different ecology than those growing at higher latitudes. [3] One of the biggest distinctions is that the lower bound of a tropical alpine area is difficult to define due to a mixture of human disturbances, dry climates, and a naturally lacking tree line.

The term tundra comes through Russian тундра from the Kildin Sami word tūndâr "uplands," "treeless mountain tract." [15] There are three types of tundra: Arctic tundra, [16] alpine tundra, [16] and Antarctic tundra [17] In tundra, the vegetation is composed of dwarf shrubs, sedges and grasses, mosses, and lichens. Scattered trees grow ...
Rachel Tenny, the host of the Plant School podcast, told Homes & Gardens that watering your plants is a natural instinct when people see something going wrong with them. “We assume the first ...
Plant species supported by tundra are generally short, lacking stems due to threats posed to vascular structure by frozen temperatures, and much of their growing matter is found below the soil. [44] They are composed mainly of perennial forbs, dwarf shrubs, grasses, lichens, and mosses. [42] [45]
