Mammal Surveys in the Greater Kuparuk Area, Northern Alaska, 2009

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 during May–August 2009. Surveys were conducted in spring, the calving season, postcalving, and late summer; no surveys were conducted during the insect season in July or in September and October due to weather and logistical problems. 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 twice in 2009, around the peak of calving (2–4 June) and near the end of calving (8–10 June). Summary maps of caribou density were prepared to compare distribution and density in 2009 with long-term averages from regional calving surveys since 1993. A helicopter was used to sample age and sex composition on 11 June. Additional aerial surveys of caribou distribution and abundance were conducted in mid-May, late June, early August, and late August in the Colville East survey area between the Colville River and the western Kuparuk Oilfield.
