THE NUMBER OF POLAR BEARS IN THE RUSSIAN FEDERATION

According to expert estimates, in the early 1990s the size of the polarbear populations inhabiting the Russian Arctic and the adjacent areas amounted to: the Kara-Barents population – 2500-5000 animals, the Laptev population – 800-1200 animals, the Chukotka-Alaska population – 2000-5000 animals. For the latter population, the estimate recommended by the Polar Bear Specialist Group of the IUCN Species Survival Commission is 2000 animals. 

Based on the results of the polar bear census conducted in 2004 in the northern part of the Barents Sea, including the area of Svalbard and Franz Josef Land archipelagos, the size of the Barents Sea part of the Kara-Barents population was estimated at approximately 2650 animals.
