The Greater Yellowstone ecosystem comprises 28 million acres of irreplaceable habitats that support one of the largest intact collections of wildlife and animal species in the lower 48 United States. At its core is the 2.2-million-acre Yellowstone National Park, the first U.S. national park and the beginning of a movement that has resulted in protected areas around the world.
