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. What’s our vision for Greater Yellowstone?
