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.

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.
