"Having to squeeze the last drop of utility out of the land has the same desperate finality as having to chop up the furniture to keep warm." - Aldo Leopold
Programs - Greater Yellowstone Ecosystem - Home
The goal of our Greater Yellowstone
Ecosystem (GYE) Protection Program is to protect the rich biodiversity, sparkling
clear air and clean water, and exceptional wilderness, recreation and aesthetic
qualities of the largest, least roaded and most intact ecosystem within the lower
48.
Grizzly bear, grey wolf, lynx
and bald eagles all call the GYE home, as do many other species including elk,
moose, wolverine and Wyoming's only native trout, the cutthroat trout.
Yellowstone National Park, the United States’ first national park, provides the GYE’s name and fertile core. The surrounding national forest and BLM lands (in addition to Grand Teton National Park) are every bit as necessary to the health and strength of the ecosystem, providing the essential habitat to allow wildlife to range in response to seasons, food needs and other varying conditions. Additionally, these wild, striking lands are highly treasured for their recreational and aesthetic resources.
The GYE is a broad and varied ecosystem where elk and deer roam from the high slopes of the Absaroka mountains down to the sagebrush steppe of the Upper Green River Valley, traversing more than a hundred miles in distance and thousands of feet in elevation; where grizzly feast on the high elevation whitebark pine seeds or the lower elevation blueberries; where the existence of a number of Class I airsheds supports the integrity of each airshed; where people and animals can experience much of this rich and awe-inspiring environment in a state still substantially unimpaired by humans.
