The tundra is a cold, treeless area; it is the coldest biome. The tundra is characterized by very low temperatures, very little precipitation (rain or snow), a short growing season, few nutrients, and low biological diversity. The word tundra comes from the Finnish word tunturia, which means "treeless plain."
There are two types of tundras, Arctic tundras and alpine tundras.
- Arctic tundras are frozen, windy, desert-like plains in the Arctic that are dotted with bogs and ponds. Permafrost (a layer of frozen subsoil) covers the ground, so there is very little drainage of water. The short growing season lasts for only 50 to 60 days. Arctic tundras are located in the far north of Greenland, Alaska, Canada, Europe, and Russia. Some animals of the Arctic tundra include:
- Mammals - Arctic foxes, Arctic hares, caribou, ermine, lemmings, musk oxen, polar bears, porcupines, Arctic shrews, squirrels, voles, weasels, wolves
- Birds - Arctic loons, snowy owls, falcons, ptarmigans, ravens, snow buntings, snow birds, snow geese, sandpipers, Arctic terns, tundra swans, many species of gulls
- Fish - cod, flatfish, salmon, trout
- Insects - Arctic bumblebees, blackflies, flies, grasshoppers, mosquitoes, and moths.
- Alpine tundras are located high in mountains worldwide, above the tree line. The growing season is about 180 days, and nighttime temperatures are usually below freezing. The soil is well-drained (unlike the Arctic tundra). Some animals of the alpine tundra include:
- Mammals - elk, marmots, mountain goats, pikas, sheep
- Birds - grouse-like birds
- Insects - beetles, butterflies, grasshoppers, and springtails.
