Canada: Large study shows caribou herds in Alberta, B.C., growing from wolf culls, cow pens

Fresh research suggests western Canada's once-dwindling caribou numbers are finally growing. But the same paper concludes the biggest reason for the rebound is the slaughter of hundreds of wolves, a policy that will likely have to go on for decades. "If we don't shoot wolves, given the state of the habitat that industry and government have allowed, we will lose caribou," said Clayton Lamb, one of 34 co-authors of a newly published study in the journal Ecological Applications.
