The habitat zone of lemmings is the cold latitudes of the Northern Hemisphere. The most common are 3 types:
Norwegian Lemming – inhabits Norway and the Kola Peninsula of Russia;
Siberian (brown) lemming – Russia (Northern Dvina – Eastern Siberia), the Alaska Peninsula, northern Canada;
Ungulates are common throughout the Arctic and Greenland.
Lemming is a small-sized rodent from the family of hamsters. In total there are about 20 species that do not differ much from each other.
The habitat of lemmings are the zones of mountain tundra and forest-tundra, arctic islands. The ideal conditions for these animals are wet and damp places.
Lemmings often follow a sedentary lifestyle in certain areas of the tundra. Animals live in burrows, which they dig themselves. The possessions of lemmings are mass meandering moves. This factor affects the microrelief and vegetation of the tundra. The burrows in winter can sometimes be right under a layer of snow. Sometimes rodents also build nests of a semi-open type from moss and twigs. From the holes in all directions are trampled paths along which the lemmings move, eating all the greens around them. These summer paths also serve in winter – the animals adhere to them, making passages under a layer of snow.
