Greater Yellowstone Coalition: People protecting the lands, waters, and wildlife of the
Greater Yellowstone Ecosystem, now and for future generations.

Phosphate mining in the Greater Yellowstone Ecosystem occurs in the upper Blackfoot River and Salt River watersheds, an area of vast roadless forests known for its impressive diversity of wildlife. It has scarred the landscape and dumped poisonous selenium into area streams in substantial amounts, killing horses, livestock and wildlife, and ruining habitat of the struggling Yellowstone cutthroat trout. Most notably, the Salt and Blackfoot river watersheds are home to two of the three largest remaining populations of Yellowstone cutthroat trout in Idaho  ̶  and a large percentage of the entire remaining population in Greater Yellowstone. The effects of land uses such as phosphate mining in this remote area can and do ripple across the ecosystem. Learn more by visiting our website.
