Status of Peary Caribou and Muskox Populations
(Rangifer taranduspearyi) and muskoxen (Ovibos moscharus) had recovered since die-offs in the early 1970s. Sampling intensity was 26%, except for 74 % over Polar Bear Pass on central Bathurst Island. Populations of 289 Peary caribou and 208 muskoxen were estimated. The proportion of calves among cla...
