Protecting the next 4.5 million acres in Greater Yellowstone

Greater Yellowstone is a place where people can experience the unparalleled wonders of one of the world’s most vibrant ecosystems. We believe Greater Yellowstone will remain healthy and wild only if it is kept whole.

Our work aims to:

  • Permanently protect vital public and private lands

  • Secure crucial habitat for Yellowstone’s iconic wildlife

  • Safeguard wildlife migration routes from Yellowstone to the Northern Rockies

Key Campaigns Include:

Defending Paradise Valley

With our efforts passing the Yellowstone Gateway Protection Act, the public lands north of Yellowstone are protected from gold mining forever. However, two foreign mining companies are still interested in placing toxic gold mines on private lands. Lucky Minerals, Inc. must do a full analysis before receiving a permit to continue their exploratory drilling. Crevice Mining Group is wanting to drill right on the border of Yellowstone and has the permit to do so, despite local opposition. We’ll continue to fight against this threat to the economy and ecosystem.

The Gallatin Range is the last large mountain range adjacent to Yellowstone National Park not permanently protected. Primarily located within the Custer-Gallatin National Forest in Montana, we are working to protect 250,000 acres of critical habitat for grizzly bears, wolves, elk, moose, and the elusive lynx and wolverine. Our goal is to protect this area of pristine, wild country on Yellowstone’s northern border through legislative and administrative solutions.

The Wildest of the Wild

Safeguarding vital public lands EAST OF YELLOWSTONE

The Absaroka-Beartooth Front lies east of Yellowstone National Park and is perhaps the wildest part of Greater Yellowstone. It includes the nation’s first national forest – the Shoshone – which supports an incredible array of wildlife. The Bureau of Land Management administers parts of the Front and the adjacent Bighorn Basin, a stunning network of sagebrush and badlands. Our goal is to work with our members and supporters to protect approximately 1.6 million acres of public lands in this area from oil & gas development, off-road vehicle use and other harmful activities.

Connecting Yellowstone to the Northern Rockies

Protecting and connecting wildlife migration routes

The land between the three great ecosystems of the Northern Rockies – Greater Yellowstone, the Crown of the Continent and central Idaho’s vast wilderness – is a complex matrix of public and private lands along Montana/Idaho border and northward, often referred to as the “High Divide.” This area is key to connecting some of Greater Yellowstone’s most iconic wildlife, such as the grizzly bear and wolverine, with other large protected areas. By working with landowners, elected officials, federal and state agencies, and our land trust partners, we aim to protect and restore the natural connectivity of lands so that wildlife can safely migrate and connect with other populations. Ultimately, our goal is to protect 700,000 acres of public land through a combination of administrative and legislative designations, as well as more than 30,000 acres of private land through conservation easements.



Just beyond west Yellowstone are the sand dunes and volcanic buttes of eastern Idaho’s Snake River Plain. Solitude and recreational escape are easily found in the sagebrush expanses that boast pronghorn, sage grouse, moose, elk and more. Idaho residents and visitors enjoy viewing and hunting migrating big game, but unconstrained motorized use threatens habitat and hunting traditions. For the first time, you have a chance to protect key areas of the Upper Snake. Click here to make sure balance is created to safeguard Yellowstone’s wildlife into the future.
