Greater Yellowstone

There are so few large, nearly intact networks of wildlands left on earth. Greater Yellowstone is one of the last.

Greater Yellowstone is defined by blue-ribbon trout streams, grizzly bears and the longest wildlife migration corridor in the continental United States. But these treasures are now threatened by expanding energy development pressures and growing populations.

At Wilderness, we're working to protect this iconic American wildland from these threats and preserve the landscape's natural and human benefits.

Stories from Greater Yellowstone

    On Bureau of Land Management (BLM) lands and National Forests, the agencies are mismanaging the use of off-road vehicles (ORVs) such as dirt bikes, snowmobiles, and all-terrain vehicles, resulting in unnecessary damage to watersheds and wildlife, and conflict with other recreationists. This is in spite of a long-standing legal obligation dating back to the 1970s that requires federal land agencies to minimize such damage and conflict.
