The Greater Yellowstone Coordinating Committee (GYCC) was formed between the National Park Service and US Forest Service in 1964 through a signed Memorandum of Understanding (MOU). The MOU provides for mutual cooperation and coordination in the management of core federal lands in the Greater Yellowstone area.

The MOU was again revised in 2002 to reflect the inclusion of the US Fish and Wildlife Service on the Coordinating Committee.

The Coordinating Committee

• The National Park Service Rocky Mountain Regional Director, the National Forest Service Intermountain Regional Forester, and the U.S. Fish and Wildlife Service Mountain Prairie Regional Director;
• Park Superintendents from Yellowstone and Grand Teton National Parks;
• Forest Supervisors from the Beaverhead-Deerlodge, Bridger-Teton, Caribou-Targhee, Custer, Gallatin, and Shoshone National Forests;
• Refuge Managers from the National Elk Refuge and Red Rock Lakes National Wildlife Refuge.

Rebecca Aus, Supervisor of the Shoshone National Forest serves as the current committee chair. The chair serves for two years and will rotate again in Spring 2010. Virginia Kelly serves as the staff for GYCC and is stationed in Bozeman, MT.
