The northern most biome on our planet is the arctic tundra. It is a treeless wet circumpolar band between the polar ice caps and the forests to the south. The predominant plants are lichens, grasses, sedges and dwarf woody plants. Despite the lack of trees, animals are found on land, in air and nearby oceans. Similar communities are found at high mountains of all latitudes forming the alpine tundra. The climate is very cold with a short growing season. The soil is frozen for most part of the year and only the top 0.5 meter melts during the short summers in the arctic tundra. The permanently frozen soil below is known as permafrost. In summer you might see huge herds of caribou, flocks of waterfowls and huge swarms of mosquitoes! With such a harsh climate it is not surprising that only a few kinds of plant and animal species are found here though, in the short growing season moss, lichens, some grasses and fast growing plants dominate the landscapes. Swarms of migratory birds invade the tundra in summer to raise their young and fly south as the summers come to an end. Some of the common permanent residents are musk ox, polar bear, grizzly bear, wolves, snowy owl, arctic hare, weasels, minks, etc. Tundra is a very fragile ecosystem as the rate of organic matter decomposition is very slow. On account of harsh climate plants grow very slowly and the tundra tak es a long time to recover from any disruptions.
