For years, GYC has advocated for infrastructure on US 20 in Idaho to mitigate wildlife-vehicle collisions and connect fragmented habitat, and a new report highlights the importance of continuing this work. Along the 45-mile stretch from Ashton to the state line, three other sections also landed among the priorities, demonstrating the need to protect this entire corridor.  

The west slope of the Tetons provide premium habitat for bighorn sheep, nesting raptors, and other wildlife — but newly approved development on public land here is likely to make their lives much more difficult. That’s a key impact of Grand Targhee Resort’s expansion plan, which the Caribou-Targhee National Forest approved in early June.

The nominee to lead the Bureau of Land Management has an anti-public lands track record. Steve Pearce’s confirmation hearing is expected to be held on February 25. Act now – contact your Senators and ask them to stand up for public lands once again by stopping Pearce’s nomination as BLM Director. 

For more than 40 years, the Greater Yellowstone Coalition has worked to ensure grizzly bears thrive across the Greater Yellowstone Ecosystem. This past year, your support made a real difference. Across the ecosystem, we advanced conflict-prevention strategies, strengthened partnerships with agencies and communities, and invested in practical tools that help people and bears thrive on shared landscapes. 

We recap our 2025 favorite conservation moments and wins in Greater Yellowstone.

A recent water quality study by researchers at Brigham Young University–Idaho found that streams near the Kilgore Gold Exploration site are highly sensitive to acid pollution, underscoring the risks that a potential open-pit, heap-leach cyanide gold mine could bring in this area.

What we’ve learned over the last four decades, and even more acutely understood in just the last few years, is that conserving a place as big as Greater Yellowstone starts small. Conservation of this beloved region begins first in conversations with friends, stakeholders, and neighbors. It’s working together with all people to build home-grown solutions that protect iconic wildlife, our public lands, and the cold, clean waters that are the lifeblood of Greater Yellowstone. And it turns out that when we work together, we’re greater.

GYC launches public lands protection campaign.

Idaho’s passage of Senate Bill 1170 weakens cyanide mining safeguards by transferring oversight from environmental experts to lawmakers, allowing mining companies to operate with fewer safety rules despite cyanide’s well-known risks. This shift endangers Idaho’s clean water, wildlife, and outdoor heritage—resources GYC is working to protect in Kilgore, where a foreign, financially unstable company is exploring for gold. Without action, an open-pit, heap-leach cyanide mine could transform this unspoiled corner of the Centennial Mountains. 

Right now, members of Congress are proposing a plan to sell-off our public lands. The very lands that unite us as Americans, that pump billions of dollars into Western states’ economies, and that have been part of our heritage for generations.  

We need you to tell Congress our public lands are NOT for sale.  

The U.S. Fish and Wildlife Service wants to hear from people who care about grizzly bears and want to help shape their future.

The Idaho Transportation Department recently secured $20.8 million in federal grant funding to build three wildlife underpasses at Rocky Point, a section of U.S. Highway 30 that has an unprecedented number wildlife-vehicle collisions every year. This funding will create safer conditions for drivers and allow one of Idaho’s largest mule deer herds to complete seasonal migrations.
