The arctic wolf’s primary biomes are the arctic & alpine tundra‚ the taiga‚ and the alpine biome. Contrary to popular belief regarding its harsh habitat and the much-publicized climate change‚ the endangerment status of the arctic wolf is listed as “Least Concern” by the IUCN and WWF‚ and‚ in fact‚ it is exactly
