President Theodore Roosevelt called Yellowstone “the best looking country on earth.” It is much more than a pretty place – it is a natural wonder. Consider these facts:

Greater Yellowstone represents:
•  An irreplaceable collection of habitats that supports the
   largest concentration of wildlife species.

•  The greatest concentration of geysers and thermal activity
    on Earth.

•  The headwaters of all three of the nation’s largest
    watersheds– the Columbia, the Colorado and the
    Mississippi– begin here.

•  It is the world’s first park and the first international
   biosphere reserve.

• 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.

Other Fast Facts
•  Yellowstone River is the longest undammed river in the
    United States.

•  Upper Snake River Valley has one of the largest complex
    of wetlands in the Northern Rockies.

•  From 1970 to 2000, the area’s population grew 61%,
   compared to 38% nationally.

•  More than two million acres have been subdivided into
   plots of 200 acres or less in the 20 counties that encompass
   the Greater Yellowstone.

•  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.
