Abstract
In 1974–75 30 muskoxen were introduced to the Bikada River area, east of Lake Taymyr on Taymyr Peninsula; 10 were from Banks Island (Canada) and 20 from Nunivak Island (Alaska). Originally kept in large enclosures, the animals have progressively been set at liberty. The first calves were born in 1978 and by the end of 1981 the population had increased to 51 animals. By this stage it was felt that the muskoxen from both source areas had completely adjusted to their new ecological conditions.
