The Richardson Mountains are home to a rich variety of wildlife species and possess a high cultural, conservation, and hunting value for northern people. The study area encompasses about 3,000 km2 and lies in the northern Richardson Mountains (67º 30' - 68º 30' N, 135º 30' - 137º W), at the northwest corner of the Gwich’in Settlement Area, adjacent to the Yukon border (fig. 1). This mountainous region is characterized by 1,250 m peaks and plateaus, interspersed with 300 m valleys. Large mammals in the study area include Dall sheep, Porcupine caribou, moose, muskoxen (Ovibos moschatus), grizzly bears, wolves, lynxes (Lynx canadensis), red foxes (Vulpes vulpes), and wolverines (Gulo gulo). Golden eagles (Aquila chrysaetos) are seasonally present in the area and may predate on sheep. Subsistence harvest of Dall sheep and wolves occurs on both sides of the Yukon and Northwest Territories border, but no resident or non-resident hunting of sheep is permitted at this time. Grizzly bear harvest in the Richardson Mountains is restricted to a triennial quota of 12 bears in the Gwich’in Settlement Area (Grizzly Bear Management Agreement in the Gwich’in Settlement Area 2000) and 12 bears in the Inuvialuit Settlement Region (Inuvialuit Game Council, Hunters and Trappers Committee, personal comm.). Although the area is presently relatively pristine, forthcoming oil and gas development in the adjacent Mackenzie Valley may leave a heavy footprint (Holroyd and Retzer 2005). Additionally, the Arctic is among the most impacted biomes by climate change (ACIA 2005, Walther et al. 2002), and a rapid warming will likely influence abundance and composition of vegetation, wildlife, and diseases. The Richardson Mountains are therefore likely to undergo significant changes in the future.
