Muskoxen in Angujaartorfiup Nunaa, West Greenland: Monitoring, Spatial Distribution, Population Growth, and Sustainable Harvest
In the 1960s, 27 muskoxen (Ovibos moschatus) were introduced to Angujaartorfiup Nunaa, which is located next to Kangerlussuaq Airport in West Greenland. Data from 12 aerial surveys of muskoxen from 1986 to 1996 show 1) that the population has stabilized at 3000 muskoxen since hunting was initiated i...
