The Polar Bear 

 research actrv'ity of the bureau of sport fisheries and wildlife 



Background: The great white bear of the Arctic, the polar bear, has long 

 been known to mankind. Polar bears, Eskimos, and igloos together commonly 

 are associated \%ith the frozen reaches of the Far North. This bear has been 

 exploited, mainly for food and fur, by the aboriginal peoples with whom it 

 coexists geographically. This exploitation, however, appears never to have 

 threatened the continued existence of the species. 



In recent years, notably since World War II, the polar bear has come to be 

 much sought as a trophy by non-native hunters. The utility of small aircraft 

 for hunting this bear far out on the Arctic ice floes, as well as increased af- 

 fluence, has done much to .stimulate this interest. The native peoples, concur- 

 rently, have found a profitable market for skins for trophy puri)oses. Increased 

 exploitation has resulted, which in turn has aroused a concern for the welfare 

 of the species.
