From this story in the Salt Lake Tribune:
_In signs the state may have a significant wolf population, the legendary predator killed sheep and cattle in Utah earlier this summer and a ranch hand shot a wolf menacing a herd. The wolf was shot by a ranch herder in southern Idaho, but that wolf had earlier attacked livestock in Cache County, Utah, said Mike Linnell, Utah director of the U.S. Department of Agriculture wildlife services. An earlier report the wolf was shot in Utah was incorrect. Linnell said wildlife agents also trapped and destroyed a wolf in Rich County, Utah, on Saturday morning. That wolf had preyed on calves in that area.

__”We’re going to have challenges if [wolves] come into Utah,” Leonard Blackham, commissioner of the Utah Department of Agriculture and Food, said. “There’s no question about it. Our mountains just aren’t secluded enough.” There have been periodic sightings of wolves in Utah for years. Less often, wolves have been blamed for killing livestock in northern Utah. In September 2002, wolves killed 15 sheep and lambs near Hardware Ranch in Cache County.

Those wolves were suspected of originating in the Yellowstone-Grand Teton area of Wyoming. Wolves were introduced into that state, Idaho and Montana in the 1990s. Ever since, there have been disputes between ranchers, environmentalists and government over how to manage the increasing numbers of wolves._
