The Greater Yellowstone Area (GYA) is a unique and special place. The 15 million acres of federal lands of the GYA are geographically contiguous, ecologically interdependent, and unalterably linked. They are managed  by four federal agencies, the National Park Service, the US Forest Service, the US Fish and Wildlife Service and the Bureau of Land Management, each with differing missions and organizational structures. The Greater Yellowstone Coordinating Committee (GYCC) allows the federal land managers of the GYA to pursue opportunities for voluntary cooperation and coordination at the landscape scale. The GYCC is formed through a Memorandum of Understanding (MOU) that documents the desire of all parties to cooperate fully in matters relating to responsible land management throughout the GYA. The GYCC is not a regional decision-making body.
