PREDATORS -- Pro-wolf groups touted a 2014 Washington State University researcher's study that indicated killing wolves involved in attacking livestock would simply exacerbate the problem long term.

In recently published dueling science, University of Washington researchers have surveyed research and found the opposite may be true.

Three UW researchers, who aren’t wildlife biologists but were intrigued by the earlier study, analyzed the same data with a different statistical approach.

Their work indicated that killing wolves that prey on livestock can lead to a short-term increase in attacks, particularly for sheep. But the year after the wolves were killed, livestock attacks went down.
