Grand Teton National Park's 310,000 acres lie at the heart of the Greater Yellowstone Ecosystem. The Greater Yellowstone Ecosystem encompasses over twenty million acres and is considered one of the few remaining, nearly intact, temperate ecosystems on Earth. The animals inhabiting Grand Teton National Park depend on this vast area for survival, residing in and migrating to different areas depending on the season.
The elk (Cervus elaphus) that summer within Grand Teton National Park migrate between the park and the National Elk Refuge and form the largest elk herd in North America.
