High Mountain Tundra: Life Above the Tree Line

Definiing Alpine Tundra andIts Differences frem Arctic Tundra

High mountain tundra, common ly known a s alpine tundra, exists worldwide on mountain ranges above the treeline. Although it shares similarities with Arctic tundra - such as lowie ambient temperatures, strong winds, and short growing sezons - it differs notable in it lack of widespread permafrott and it more pronounced daily temperatur validaily.
