As a keystone species — organisms who play an outsized part in shaping their ecosystem — beavers and the wetlands they maintain serve a unique and irreplaceable role in the Greater Yellowstone Ecosystem. Beavers are also ecosystem engineers, second only to humans in their ability to alter a landscape. By cutting wood and building dams, beavers do more than just build dams.

Rivers are the lifeblood of Montana. A low snow year, coupled with the impacts of population growth and climate change, are stark reminders that our rivers need our help. That’s why now is the time to pass the Montana Headwaters Legacy Act (MHLA). As we anticipate the bill’s hearing this spring, we critically need Senator Daines to support the MHLA.

Buckle up! It’s going to be a big year for GYC and the lands, waters, and wildlife of Greater Yellowstone.

Join us for a journey down memory lane and let’s celebrate all we did together for the Greater Yellowstone Ecosystem.

The Montana Headwaters Legacy Act (MHLA) is back in U.S. Senate. We need you to help make it law.

The New York Times Monday captured our collective win of protecting Yellowstone National Park from the last viable gold mining threat along the park’s northern border.

On September 25, 2023, the Greater Yellowstone Coalition raised the $6.25 million needed to stop the mine on Crevice Mountain, just north of Yellowstone National Park. People from across the country and globe gave to stop this mine, proving once and for all that Yellowstone is more valuable than gold.

Water is a defining, dynamic, and driving force in the Greater Yellowstone Ecosystem. The ecosystem’s wild rivers are so significant to its identity that Greater Yellowstone is often called “the headwaters of the West.” But what does it really mean to be “the headwaters of the West?”

The Greater Yellowstone Coalition announces an ambitious campaign to buy out a mining company on the northern border of Yellowstone National Park. If successful, the effort would extinguish the last real and significant mining threat on the border of Yellowstone National Park, forever.

GYC is celebrating 40 years of working with all people to protect the lands, waters, and wildlife of the remarkable Greater Yellowstone Ecosystem.

As a part of GYC’s Tribal work, we’re gathering people together to dive into impactful stories, photos, and film that showcase the social, economic, and cultural injustices against Indigenous People.

In a huge show of support, advocates sent thousands of letters to the Montana Department of Environmental Quality demanding a healthy Gallatin River.
