Synopsis

Across the breathtaking expanse of Yellowstone, where wolves, bears, coyotes, bison, and elk traverse grasslands, wetlands, and forests, Steve Backshall seeks to unravel a mystery. Wolves and beavers appear to have no natural connection, so why did the beaver population flourish after the wolves' reintroduction, a return that had been absent for seven decades? The answer, it turns out, is both enchanting and unexpected.
