It appears that the Porcupine caribou herds of Alaska and Canada are on the rebound. Preliminary counts from the 2010 photo census put population counts over the previous count of 123,000 from 10 years ago. However the final numbers are still being compiled and won't be known for a few months. CBC.ca  has the full story.
With other caribou herds in decline across the North, wildlife managers in both Alaska and Yukon had feared the worst for the cross-border Porcupine herd. In 2009, the Yukon government imposed controversial hunting restrictions along the Dempster Highway, in an effort to protect herd numbers. The Yukon government says news of the higher caribou numbers means officials can review the hunting restrictions along the Dempster Highway.
