Alaska Department of Fish and Game, July 2014: Alaska‘s largest caribou herd, the Western Arctic Herd, numbered about 235,000 animals as of July 2013 […] That’s down from 325,000 caribou estimated in the 2011 census […] The recent census indicates a decline of about 27 percent [actually 27.7%] since 2011. Mortality was very high during 2011-2012 […] In addition to high adult cow mortality during 2011-2012, survival of calves born during 2011 and 2012 was relatively low.
Jim Dau, ADF&G biologist who has worked with the herd for more than 25 years: “The herd size right now, as of 2013, was 235,000 caribou, and that’s down about 27% since 2011 — so, a big, big decline in the last two years.”

Canada: Yukon To Test For Radiation In Caribou Herd
– Yukon to test for radiation in caribou herd (CBC NEWS, Aug 19, 2011):
Researchers plan to test for radiation in Yukon’s local food supply some six months after a Japanese nuclear disaster.
The Northern Contaminants Program will test caribou for radiation as part of its ongoing effort to monitor the Porcupine Caribou Herd.
The move comes after a nuclear power plant in Japan was severely damaged in March following an earthquake and tsunami, which spewed radiation into the air and water for weeks after the accident.
