PREDATORS -- Wildlife Services say they had already removed 12 wolves from an area where 176 sheep died in a stampede during an attack by two wolves on Saturday.  They've removed at least one more wolf since that incident.

Of the 13 trapped and euthanized wolves, four were adults or sub-adults, an official said. Nine of the wolves killed were pups.

According to the story in the Jackson Hole News and Guide:

The pack’s demise was already underway when two wolves thought to be Pine Creek members ventured into a 2,400-head sheep herd early Saturday morning. The herd, owned by the Siddoway Sheep Company of St. Anthony, Idaho, was bedding down on Caribou-Targhee National Forest land between Pole Canyon and Fogg Hill, about 5 miles south of Victor.

Running downhill in a panic, about 165 sheep from the Siddoway herd were  killed, trampled and smothered in their terror. Two wolves, which were witnessed by a herder at the scene, killed about another dozen sheep. The final tally: 119 lambs and 57 ewes dead. Price tag: $20,000.
