Tundra, the ice desert, frozen prairie, the cold plains of the Far North get their name from the Finnish word tunturia, which means treeless land. The tundra biome is the coldest of all terrestrial eco-systems, and also the most chaotic. Still, the tundra is host to a surprising number of plants and animals, and represents a fascinating testament to nature's adaptability, and cruel beauty. The arctic tundra occupies earth's Northern hemisphere, circling the North Pole all the way down to the evergreen forests of the boreal biomes. The arctic tundra sees little rainfall, like the cold deserts of russia. The soil of the arctic tundra is poor in nutrients, which accounts for the low amount of vegetation.
