There are three regions and associated types of tundra: Arctic tundra, [2] alpine tundra, [2] and Antarctic tundra. [3] Tundra vegetation is composed of dwarf shrubs, sedges, grasses ...

Arctic tundra is the northernmost (and coldest) of European habitats, in extreme northern Scandinavia, Svalbard archipelago, northernmost part of Russia. Some typical animals include reindeer, Arctic fox, brown bear, ermine, lemmings, partridges, snowy owl and many insects. Most tundra animals undergo hibernation during the colder season.
Other mammals include lemmings, polar bear, walrus, beluga whale, snowshoe hare and Arctic hare, red fox, grey wolf, Arctic ground squirrel and seals. The coast is also home to many breeding waterbirds including snow goose , spectacled eider , Steller's eider , king eider , red-throated loon , [ 3 ] pacific loon , [ 4 ] and yellow-billed loon .
A focus of the latest Arctic evaluation was the effects of warmer weather and wildfires on the tundra, a far-northern biome that's typically known for extreme cold, little precipitation and a ...
