      The Greater Yellowstone Ecosystem (GYE) is one of the last remaining large, nearly intact ecosystems in the northern temperate zone of the Earth. It is located within the northern Rocky Mountains, in areas of northwestern Wyoming, southwestern Montana, and eastern Idaho, and is about 22 million acres. Yellowstone National Park and the Yellowstone Caldera 'hotspot' are within it.

      Conflict over ecological and resource management has been controversial, and the area is a flagship site among conservation groups that promote ecosystem management. The Greater Yellowstone Ecosystem (GYE) is one of the world's foremost natural laboratories in landscape ecology and Holocene geology, and is a world-renowned recreational destination. It is also home to the diverse native plants and animals of Yellowstone.
