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 .
An alpine mire in the Swiss Alps. The adaptations for survival of drying winds and cold may make tundra vegetation seem very hardy, but in some respects the tundra is very fragile. Repeated footsteps often destroy tundra plants, leaving exposed soil to blow away, and recovery may take hundreds of years. [37]
The vegetation is alpine and subalpine. The ground cover is 23% low herbaceous cover, 19% shrub, 17% is closed evergreen forest, 11% is open forest, and 28% is bare or has sparse vegetation. [3] The open forest is characterized by discontinuous stands of white spruce (Picea glauca), alpine fir (Abies lasiocarpa) and lodgepole pine (Pinus contorta).
The hills that circle the refuge lowlands are capped by alpine tundra. It takes a week in a canoe, or more than an hour in a small plane, to traverse the refuge's 2,100,000 acres (8,500 km 2 ) of pristine wildlife habitat.

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 ...
