In Early April, Refuge and Alaska Department of Fish & Game conducted a cooperative aerial survey of overwinter calf survival in the Northern Alaska Peninsula Caribou Herd. Although the sample size (1,500 caribou) was below ideal levels because of poor snow-cover conditions, researchers estimated calf to cow ratios of 20:100.


In addition, four adult female caribou were captured and fitted with radio-collars. New collars replaced four collared caribou mortalities from 2009–2010.  The addition of the collars increases the number of radio-collared caribou available to track during future surveys of the same caribou herd.
