Yellowstone Battleground: Grizzly Cauldron (2009x4)
Air date: Apr 18, 2009
Grizzlies once reigned unchallenged as the top predators of Yellowstone, but everything changed when an old rival returned to the landscape. After almost a century without them, wolves were reintroduced to Yellowstone and again play a vital role in the ecosystem that depends upon them. Once the sole rulers of this vast kingdom, grizzly bears are now re-learning how to cope with the rise of an equal competitor.
