Killing predators such as wolves, mountain lions and bears in order to protect livestock may have intuitive appeal, but a rigorous review of multiple studies that was published today shows little or no scientific support that it actually reduces livestock losses. In fact, in some cases it even leads to increases in livestock loss. These conclusions directly counter the reasoning behind the common practice of killing predators in response to livestock depredations--as carried out by the secretive federal program, Wildlife Services, and many state game agencies.
"This study [paywalled] shows that not only is Wildlife Services' annual killing of tens of thousands of wolves, coyotes, bears, bobcats, cougars, and other animals unconscionable--it's also ineffective", said Michael Robinson of the Center for Biological Diversity. "Our government should ground the aerial snipers, pull the poisons and remove the steel leghold traps in response to these findings."
The unexpected finding that carnivore killings can increase depredations is likely based on disruption of the predators' social dynamics--namely, by removing dominant animals that maintain large territories, these killings release sub-adult animals that are less-skilled hunters and thus more likely to target domestic animals.

So which wolves were killed? The ones actually killing livestock or random ones in the forest that might not have been killing livestock? If it's the latter then there's the problem.
When I was living in alaska about 10 years ago, they were shooting wolves from planes to protect the caribou herd. So it was pretty much the same wolves in the wild that were doing the killing.
Few if any cattle ranchers were around.
The political push for this wolf control at that time was the Alaskan Native population and a few other hunters complaining about the dwindling herd. At that time the Porcupine Caribou herd (sub species of Caribou in parts of Alaska and Canada) was in decline, and the subsistence hunters, (preferentially Natives by law) were having trouble getting enough meat for the winter.
No, you are mistaken. I've always had this sig.
