Animals and plants that live in Russia's tundra region

The tundra, which extends along the extreme northern part of Asia, is divided into arctic, moss-lichen, and shrubby tundra subzones. Only dwarf birches, willows, lichens, and mosses grow in the thin layer of acidic soil. Indigenous fauna include the arctic fox, reindeer, white hare, lemming, and common and willow ptarmigan.
