Yellowstone cutthroat trout once occupied habitat across Montana, Wyoming, Idaho, and slivers of Nevada and Utah. Now, they are in steep competition with nonnative fish for habitat and resources. To help give the Yellowstone cutthroat trout a leg up, GYC staffers volunteered to work with partners to remove invasive brook trout from Mill Creek, a slow-moving stream near Yellowstone National Park’s northern border.

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.

In late 2023, the Wind River Indian Reservation, the Eastern Shoshone and Northern Arapaho Tribes, and the Greater Yellowstone Coalition received a $619,500 grant from the National Fish and Wildlife Foundation (NFWF) and through its America the Beautiful Challenge.

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.

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?”

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