Saving Yellowstone with Dennis Quaid

High in the mountains, over 10,000 feet up, an unlikely champion stands: the whitebark pine. This resilient tree sustains life, providing food and shelter for animals like the grizzly bear, red squirrels, and more.

Follow three key predators of Yellowstone: the wolf, red fox and coyote. These canids are now studied by Grand Teton scientists in a multi-year tagging project to discover how people and predators can coexist.

Seven major rivers originate from the Continental Divide, shaping the Yellowstone landscape and sustaining diverse wildlife. Amid threats like drought and climate change, the ecosystem relies on its river and an unlikely hero: the beaver.

Yellowstone is one of the world's largest intact temperate ecosystems. As nearby populations grow, creatures like the red squirrels, pygmy rabbits, and pelicans are vital indicators, helping scientists uncover ways to adapt to a changing environment.
