Nat Geo Live: Wild Wolves of Yellowstone

Witness the beauty and wonder of Yellowstone National Park with wildlife biologist Doug Smith.

Yellowstone National Park’s two million acres of wilderness contain many stories, including one of the best case studies in wildlife conservation. Doug Smith led the project that reintroduced gray wolves to Yellowstone in the 1990s. Go behind the scenes—including never-before-seen photos and videos—of the quest to bring wolves back and the incredible changes that happened after they arrived.

Doug Smith served as a wildlife biologist at Yellowstone National Park for nearly three decades and studied everything from beavers to birds.

He’s written numerous scientific publications and has been featured in four National Geographic television specials.
