Our goals are to monitor the movements, distribution and health of the Western Arctic Caribou Herd. The caribou use different Park units at different times of year. Further, the timing and spatial pattern of the herd’s migration plays a critical role in the harvest of caribou by rural villages. Changes to these patterns may affect these subsistence users. Herd productivity and health will be monitored using a variety of different indices.

Climate change is likely to bring a myriad of interrelated changes to the Arctic. One change is warmer and drier conditions that could increase the prevalence of wildfire in northwest Alaska. Wildfires destroy terricolous lichens that Western Arctic Herd caribou ( Rangifer tarandus ) rely on during winter; taking decades to recover. My goals were to assess the recent (1950-2007) fire regime within the herd's range, identify characteristics of habitat selected by overwintering caribou, and determine the potential impacts of climate change on the fire regime and caribou winter range. I used a combination of existing data and information collected at vegetation plots to conduct these analyses. I found that wildfires...
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...
