From the Gillette News Record:
“Those who say wolves are responsible for the decline in elk populations are missing the big picture, Smith said. Bears and mountain lions also eat wolves, but food abundance or shortage, in ebb and flow patterns on the landscape, affect the populations more than any predator, Smith said.
“Humans,” he said, “are the leading cause of wolf mortality everywhere.”
Smith said he is surprised how many wolves get hit by cars.”
