Caribou Monitoring Study For The Alpine Satellite Development Program, 2008
Recent discoveries of oil in the northeastern National Petroleum Reserve–Alaska (NPRA) led to a proposal by ConocoPhillips Alaska (CPAI)—the Alpine Satellite Development Program (ASDP)—to expand development from the Alpine facilities on the Colville River delta and into NPRA. The first ASDP facility to be constructed (winter 2004–2005) was the CD-4 drill site and access road. The North Slope Borough (NSB) development permit for CD-4 stipulated that a 10-year study of the effects of development on caribou distribution and movements be conducted within a 48-km (30-mi) radius of CD-4, which encompasses CD-3 (also constructed in winter 2004–2005) and the planned CD-5, CD-6, and CD-7 pads and associated infrastructure and activities proposed by CPAI. • This report presents results from the fourth year of the ASDP caribou monitoring study, combining analyses of data from aerial-transect surveys, radio telemetry, and remote sensing. Aerial strip-transect surveys of caribou distribution were conducted in three adjacent survey areas (NPRA, Colville River Delta, and Colville East) from April to October 2005–2008, and similar data from earlier studies in those areas during 2001–2004 also were analyzed. The telemetry analyses used location data from VHF, satellite, and GPS radio-collars in the Teshekpuk Herd (TH) and Central Arctic Herd (CAH) collected by the Alaska Department of Fish and Game (ADFG), the Bureau of Land Management (BLM), the NSB Department of Wildlife Management, and the U.S. Geological Survey (USGS). VHF-collar data were collected during 1980–2005, satellite-collar data were collected during 1990–2008 for the TH and 1986–1990 and 2001–2005 for the CAH, and GPS-collar data were collected during 2004–2008 for the TH (including 30 new collars deployed specifically for this study in early July 2006, late June 2007, and late June–early July 2008) and during 2003–2006 and 2008 for the CAH (including four new collars deployed specifically for this study in early July 2008).
