GRANTS PASS, Ore. – Scientists have found that, contrary to what many people think, killing wolves does not always reduce attacks on livestock.
Researchers at Washington State University found that for every wolf killed in Idaho, Montana and Wyoming over the past 25 years, there was a 5 percent increase in the sheep and cattle killed the next year. Livestock kills only started going down after overall wolf numbers were reduced by more than 25 percent.
