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.
While millions of acres within the Greater Yellowstone are protected through park, national forests and wildlife refuge status, the areas of greatest biological importance, about 10% or 2.8 million acres, are not protected. These areas are the crucial winter feed grounds that are necessary for the survival of species such as elk and pronghorn.
Working with others we aim to protect 1 million acres, or the most important 4 percent of all Greater Yellowstone wildlife habitat, by 2015. We also strive to accelerate public policy efforts to identify sustainable funding for conservation within the region, and work on the ground in six priority landscapes within Idaho, Montana and Wyoming.
