Alpine tundra is a type of natural region or biome that does not contain trees because it is at high altitude. Alpine tundra is distinguished from arctic tundra, because alpine soils are generally better drained than arctic soils. Alpine tundra transitions to subalpine forests below the tree line; stunted forests occurring at the forest-tundra ecotone are known as Krummholz.
Alpine tundra occurs in mountains worldwide. The flora of the alpine tundra is characterized by dwarf shrubs close to the ground. The cold climate of the alpine tundra is caused by the low air pressure, and is similar to polar climate.

Famous quotes containing the word alpine:
“I held a bayonet
that was for the earth of your stomach.
The belly button singing its puzzle.
The intestines winding like the alpine roads.
It was made to enter you
as you have entered me....”
—Anne Sexton (1928–1974)
