Steve Backshall looks for the answer to a puzzle involving wolves and beavers.

In Yellowstone National Park, where wolves, bears, coyotes, bison and elk roam vast grasslands, wetlands and forests, Steve Backshall looks for the answer to a puzzle.

In the spectacular Yellowstone where wolves, bears, coyotes, bison and elk roam vast grasslands, wetlands and forests, Steve Backshall looks for the answer to a puzzle. Wolves and beavers have little to do with each other so why, when wolves were returned after an absence of 70 years, did the beaver population increase? The revelation is as magical as it is surprising.
