Yellowstone Wolves: The Renewal of Nature Trailer (2021)
The 'Wapiti Lake Pack' is the largest wolf pack in Yellowstone. For centuries, humans were hunting and eradicating them from almost everywhere including Yellowstone; the world's first national park. In 1926 the last of the wolves were killed. Then, in 1995, 70 years after their extermination, the wolves were resettled in Yellowstone National Park, where they restored an entire ecosystem that was out of balance. This documentary follows the White Alpha Wolf of the 'Wapiti Lake Pack and her pack and shows how the wolves have rebalanced the ecosystem.
