Overview

Greater Yellowstone

President Theodore Roosevelt called Yellowstone “the best looking country on earth.” It is much more than a pretty place – it is a natural wonder. Yellowstone holds the world's greatest concentrations of geysers and thermal activity. The headwaters of all three of the nation's largest watersheds—the Columbia, the Colorado and the Mississippi—begin here. It's the world's first park and the first international biosphere reserve. Each year millions of people from all over the world come here for enjoyment, inspiration and to experience a place where the land and wildlife remain in a natural setting. 

Yellowstone is often called a land of superlatives. The Greater Yellowstone represents:

•  An irreplaceable collection of habitats that supports the largest concentration of wildlife species.

• The location of the five longest remaining long-distance mammal migrations– one of the Earth’s most stunning and imperiled biological phenomena–in the lower 48 United States.

•  Habitat for large concentrations of elk, mule deer, bighorn mountain sheep, bison, and pronghorn, and the southern anchor of a larger system for wide-ranging carnivores that are critical to the natural balance: wolves, grizzly bears, coyotes mountain lions, wolverine, lynx, and fox.

•  The site of the discovery of the world’s oldest living organisms–single cell species living in the hot springs that are so unique that scientists assigned these species    their own kingdom.

•  Home to 109 other species or communities considered to be imperiled globally, including critical habitat for the world’s largest swan, the trumpeter swan.

•  Some of the best remaining waters for native cutthroat trout, restricted by habitat loss and competition from introduced species to 15% of its original range.

•  Numerous endangered or threatened species including grizzly bear, wolf, trumpeter swan, boreal owl, black-footed ferret, peregrine falcon, and the bald eagle.
