Well I live in Idaho, and I can tell you from first hand experience that the number of Elk have dropped significantly. Not only that, but they bugle less because the wolves close in fast when they are hear them, and we have gone to hearing wolves, to seeing one or two 1000 yards away to seeing a couple of packs a year as close as 75 yards away. Just like any other big game animal they have to be managed. I don't think there is any debate in that. My good friend is a park ranger in Yellowstone. He worked with releasing wolves and tracking them in the park. He loves them, and grew very close to several of them. I was shocked when he told me that because he is a biologist and looks at the overall picture, wolves need to be managed. I don't know how you disagree with a biologist who likes the wolves saying that they have to be managed.
