The most numerous group of animals that live in these regions – a lemming and arctic hare. However, in order to survive, the wolf flock sometimes needs and larger prey. Such may be musk oxen and reindeer, but they rarely come to these territories. Therefore, wolf flock should bypass an area covering 2,000 square kilometers. In winter the temperature drops.
