Mammal Surveys in the Greater Kuparuk Area, Northern Alaska, 2010
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 late winter to fall 2010. Surveys were conducted in late winter (April), the calving season (early June), postcalving (late June), late summer (early and mid-August) and fall (mid-September). No surveys were scheduled during the insect season in July. Neither of two surveys scheduled in October could be conducted because of persistent inclement weather. 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 calving distribution and abundance of caribou once in 2010, near the end of calving (8–9 June). Summary maps of caribou density were prepared to compare distribution and density in 2010 with long-term averages from regional calving surveys since 1993. A helicopter was used to sample age and sex composition on 11 June.
