Moose, WY – Grand Teton National Park officials say the first calf to be killed by a wolf happened earlier this week. Officials says the Hereford calf was attacked late Tuesday or early Wednesday on the Elk Ranch grazing allotment near Moran Junction in the northeastern part of the park. Two federal wolf managers discovered the carcass and a federal wolf expert verified the calf was killed by a wolf. Officials say wolves have denned in the area since 1999 with virtually no incidents regarding livestock. Grand Teton staffers plan to monitor the area, but no other actions will be taken for now.
