Mammal Surveys in the Greater Kuparuk Area, Northern Alaska, 2012

The focus of this study was the distribution, abundance, and calf production of Central Arctic Herd (CAH) caribou between the Colville and Kuparuk rivers in northern Alaska from spring to fall 2012. Surveys were conducted in spring (mid-May), the calving season (early June), postcalving (late June), late summer (mid-August), and fall (early October). Another survey planned for mid-September was cancelled due to poor weather. No surveys were scheduled during the insect season in July. Incidental sightings of other species of large mammals were recorded during aerial surveys for caribou and other species (mainly birds).

A fixed-wing airplane was used to survey the distribution and abundance of caribou once during calving in 2012 (8–10 June). An earlier calving survey was not completed due to persistent fog and other inclement weather in early June. Summary maps of caribou density were prepared to compare calving distribution and density in 2012 with long-term averages from regional calving surveys conducted since 1993. A helicopter was used to sample the age and sex composition of caribou groups on 12 June.
