Wildlife managers have been foiled so far in attempts to eliminate a large wolf pack that has shed bovine blood in the Bondurant area all spring.

Once numbering 16 wolves but cut by aerial gunning to 11 animals, the Dell Creek Pack has persistently preyed on cattle on private ranchland about 25 miles southeast of Jackson. U.S. Fish and Wildlife Service officials aren’t tolerating the depredation and have made plans to kill all of the pack’s members.

“There’s been nine, possibly 10 livestock depredations by that pack,” said Mike Jimenez, the service’s Northern Rockies wolf coordinator. “There’s been a couple that have been newborns, but most of them have been large 400-, 500-pound calves from last year. When packs do that and they do that over and over again, we’ll probably remove that pack.”

“I won’t sugarcoat it or anything,” Jimenez said. “We’ll remove that entire pack.”

But the Dell Creek wolves have evaded “several” planes dispatched to carry out the task so far. On behalf of Fish and Wildlife, the U.S. Department of Agriculture’s Wildlife Services conducts the lethal operations.

The wolves “clearly” have smartened up to the sound of aircraft, a behavior that Jimenez has seen before.

“When wolves have been darted before and there’s a helicopter, you see them go for the trees immediately,” he said.

Because it’s the lowest-cost option, a small fixed-wing aircraft has been used for the flights. The strategy could potentially shift to trapping or ground-based calling and shooting, but Jimenez’s guess was that they will stick with the aerial approach.

Wolf-livestock conflict in Wyoming this spring has been mostly confined to the Hoback Basin, although two weeks ago four wolves were eliminated from the 15-animal Warm Springs Pack near Dubois after killing two cattle.

Also near Bondurant, the Rim Pack, a group of eight wolves, was in federal officials’ crosshairs after killing cattle in the same pastures where the Dell Creek Pack has been causing trouble. The pack — which made national headlines last month after “surplus killing” 19 elk at the McNeel Feedground in a night — quickly fled and was reduced by only one animal.

“That’s all we could get,” Jimenez said. “If we could have got more, we would have taken more.”

Lethal control is a routine way to dissuade wolves from preying on livestock. If removing a portion of a pack doesn’t break the behavior, whole packs are sometimes eliminated.

In 2015, a heavy year for conflict, 54 Wyoming wolves were killed in response to depredating 72 cattle and 62 sheep. Two wolf packs were altogether removed. Canis lupus is confirmed to have killed 12 cows and 19 sheep in Teton County, Fish and Wildlife reports show.

Nonlethal techniques to deter the Dell Creek and Rim packs have not been attempted this spring in the Hoback Basin, where conflict has been chronic.

The Dell Creek Pack didn’t form until 2014, and in its first couple years of existence it stayed out of trouble despite roaming territory with ample private ranchland.

Given the time of year, it’s likely the pack is raising puppies in the area, Jimenez said. Dens make wolves less mobile and able to follow natural prey like elk and deer that in springtime are migrating into higher-elevation areas.

“There’s 11 wolves in there right now, and they’re denning in an area with lots and lots of livestock,” Jimenez said.

Look up Wyoming ranching revenues compared to cattle revenues in he Southeast. You will find the facts. i have studied wolves and ranching in the West for many years. I will bet your cattle ranching friend receives federal subsidies. As a true capitalist, all such subsidies should be abolished. And also no cattle or livestock should be run on public lands. The Old West is gone. The land and its creatures have been subduded or destroyed. Just leave the wildlife alone.

Catherine- your ignorance is showing---- nearly everything you said is a flat out un truth--- I know the man and ranch this happened on--- number one its private land- number two his one man operation would have t hire at least 4 others to do round the clock surveillance--- not that that matters-- how do you shoot a wold in the dark thats attacking you income? I encourage you to look up our state revenues---- agriculture is second only to oil and gas for money makers in this state--- and folk may come to yellowstone but they don't drop tourism dollars elsewhere--- May the great creator give you common sense and rid our pastures of wolves---

Once again, idiocy and abuse of Nature triumphs in Wyoming. Why don't these ranchers take care of their cattle? Where are the range riders? Where are the guard dogs. Ranching contributes almost nothing to the Wyoming economy--in fact, ranching contributes almost nothing to any state west of the Mississippi. Tourism brings money to Wyoming--tourism and mineral extraction. People come from around the world just to breathe the same air as wolves and Grizzlies. They do not come to smell the cattle. May the Great Creator save the wolves. And end those who destroy them and despise Nature.
