Tundra is separated into two types : Arctic Tundra and Alpine Tundra.
Characteristics of Tundra
- Extremely cold climate
- Low biotic diversity
- Simple vegetation structure
- Limitation of drainage
- Short season of growth and reproduction
- Energy and nutrients in the form of dead organic material
- Large population oscillations
- low shrubs, sedges, reindeer mosses, liverworts, and grasses
- 400 varieties of flowers
- crustose and foliose lichen
Alpine tundra is located on mountains throughout the world at high altitude where trees cannot grow. The growing season is approximately 180 days. The nighttime temperature is usually below freezing. Unlike the arctic tundra, the soil in the alpine is well drained. The plants are very similar to those of the arctic ones and include:
- tussock grasses, dwarf trees, small-leafed shrubs, and heaths
- Mammals: pikas, marmots, mountain goats, sheep, elk
- Birds: grouse like birds
- Insects: springtails, beetles, grasshoppers, butterflies
This Weasels live in the Arctic Tundra. Since the Weasel sheds it fur near the end of Autumn, its new white coat grows back thicker for the winter. This way, it's able to stay warmer throughout the frosty season in the Tundra.
The Snowy Owl is from the Arctic Tundra also just like the weasels. Range- Northern Canada and Alaska. They prefer open spaces like tundra, grasslands, or frozen lakes.
The Arctic Fox live in the Tundra. They live in dens or burrows, where they raise their young. The Arctic Fox is found throughout the entire Arctic tundra, through Alaska, Canada, Greenland, Russia, Norway, Scandinavia, and even Iceland, where it is the only native land mammal.
