Joly, Kyle, 2013, Caribou vital sign annual report for the Arctic Network Inventory and Monitoring Program: September 2012-August 2013: National Park Service: Fort Collins, Colorado, v. NPS/ARCN/NRDS—2013/586.
Summary
Caribou (Rangifer tarandus) are an integral part of the ecological and cultural fabric of northwest Alaska. Western Arctic Herd (WAH) caribou roam over this entire region, including all 5 Arctic Network Inventory and Monitoring Program (ARCN) National Park Units. Conservation of healthy caribou populations are specifically mentioned within the enabling legislation (Alaska National Interested Lands Conservation Act or ANILCA) of three of these Parks and is of critical concern to subsistence hunters within this region. Caribou are, by far, the most abundant large mammal in northwest Alaska and are famous for their long-distance migrations and large population oscillations. For these reasons, ARCN chose WAH caribou as a Vital Sign for [...]
Summary
Caribou (Rangifer tarandus) are an integral part of the ecological and cultural fabric of northwest Alaska. Western Arctic Herd (WAH) caribou roam over this entire region, including all 5 Arctic Network Inventory and Monitoring Program (ARCN) National Park Units. Conservation of healthy caribou populations are specifically mentioned within the enabling legislation (Alaska National Interested Lands Conservation Act or ANILCA) of three of these Parks and is of critical concern to subsistence hunters within this region. Caribou are, by far, the most abundant large mammal in northwest Alaska and are famous for their long-distance migrations and large population oscillations. For these reasons, ARCN chose WAH caribou as a Vital Sign for longterm monitoring.This report documents the monitoring results of this Vital Sign during its 4thyear (September2012 – August 2013) of implementation. Results from the first 3 years of monitoring are also included for ease of comparison. Periodic syntheses of these data will be performed and reported on as appropriate. National Park Service (NPS) monitoring of the WAH is done in conjunction and cooperation with the Alaska Department of Fish and Game (ADFG), US Fish and Wildlife Service (FWS) – Selawik National Wildlife Refuge, and Bureau of Land Management (BLM) –Central Yukon Field Office. NPS-sponsored monitoring of the herd relies heavily on the use of Global Positioning System (GPS) radiotelemetry collars that are capable of transmitting location data to a satellite. Given the extremely remote area that the WAH inhabits, this system provides the most efficient and accurate means to track individual caribou. These data are being utilized to monitor the timing and location of migrations, as well as seasonal distributions of WAH caribou. Monitoring phenology of movement is perhaps the simplest means to track the influence of climate change, natural perturbations, development, and other potential impacts on a species – an analysis of which is outside the scope of this current report.This report also documents the NPS commitment and involvement with the WAH Working Group. The group is composed of important stakeholders including representatives for rural villages, sport hunters, conservationists, hunting guides, hunting transporters, and reindeer herders. In addition, all of the agencies charged with managing the WAH, including the ADFG, NPS, FWS and BLM, serve as advisors to the group. Information gathered by the Caribou Vital Sign monitoring program are intended to supplement and complement existing data streams gathered by the other cooperating agencies and will be of vital importance in future management decisions.
