Mission

The Greater Yellowstone Coalition (GYC) was founded in 1983 to protect the lands, waters, and wildlife of the Greater Yellowstone Ecosystem, now and for future generations. Since that time, we have emerged as a nationally known advocate for the idea that ecosystem level sustainability and science should guide the management of the region's public and private lands. This vast ecosystem includes twenty million acres of wild country that includes Yellowstone and Grand Teton national parks, parts of six national forests, three national wildlife refuges, and state and private lands in Wyoming, Idaho, and Montana. We work to ensure that a thoughtful and holistic approach is taken to managing the national and wildlife resources in harmony with people and modern development.
