Study shows effectiveness of nonlethal wolf deterrents

A seven-year study of the Wood River Wolf Project shows nonlethal deterrents to have been more than three times as effective as lethal control in reducing depredation on sheep. The study’s results were published in the February issue of the Journal of Mammalogy. The paper’s seven authors include people involved in the project, which seeks to protect up to 22,000 sheep belonging to four ranchers each grazing season on nearly 1,000 square miles of the Ketchum Ranger District. The project uses shepherds, guard dogs, noisemakers and lights to scare off wolves.“ This is the first peer-reviewed study using nonlethal deterrents to protect both livestock and wolves across a large landscape,” said Suzanne Stone, Northwest senior representative for the conservation organization Defenders of Wildlife and primary author of the study.
