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 .
The Interior Yukon–Alaska alpine tundra ecoregion (WWF ID: NA1111) covers alpine, sub-alpine, and boreal forest areas along the cordillera (chain of mountain ranges) of Interior Alaska and south-central Yukon Territory. Geologically, they are the disjunct uplands of the Yukon–Tanana terrane plus a southern extension of the Brooks Range. The ...
In physical geography, tundra (/ ˈ t ʌ n d r ə, ˈ t ʊ n-/) is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. There are three regions and associated types of tundra: Arctic , [ 2 ] Alpine , [ 2 ] and Antarctic .

The tundra region is found in high latitudes, primarily in Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, as well as the Antarctic Islands. Consisting of the arctic, alpine, and Antarctic regions, and stemming from the Samer language, tundra literally means a "high and dry place".
The Köppen climate classification is "ETH": Alpine tundra, with no month with an average temperature in excess of 10 °C (50 °F). [4] [5] Where the Northern Andean páramo is generally humid throughout the year with moisture delivered in the form of rain, clouds and fog as air masses are lifted up over the mountains, the Cordillera de Merida páramo is similar to the Costa Rican páramo and ...
The alpine tundra of Rocky Mountain National Park taken along the Tundra Communities Trail at approximately 12,000 feet. Region 2 is the alpine region of the park with accessible tundra trails at high elevations—an area known for its spectacular vistas. [ 36 ]
The truest alpine tundra communities are located on the harsh western and northwestern slopes of tall mountains. The western slopes are typically heath dominated communities composed of plant of the family Ericaceae , changing to grasses and sedges toward the harsher northwestern faces.
