Tom Bergerud top wolf expert from BC told the IDFG the following:
"I predict that you´re going to have major impacts from wolves in this state," (Idaho) he said. I predict a major elk decline.
He said that he saw wolves "repeatedly depress moose, caribou and elk populations while studying them throughout Canada and in some cases they wiped out local populations of caribou."
"I've watched herd after herd (of caribou) go EXTINCT across Canada," he said. The problem: wolves have no known predators to keep them in balance with the ecosystem..”
