The plant communities of Bighorn National Recreation Area and Grand Teton and Yellowstone national parks include overlapping combinations of species typical of the Rocky Mountains as well as of the Great Plains to the east and the Intermountain region to the west. Their composition reflects the consequences of the underlying geology, ongoing climate change, and disturbances created by fire, floods, landslides, insect infestations, and the arrival of non-native plants. Yellowstone is home to three endemic plant species, at least two of which depend on the unusual habitat created by the park’s thermal features. Most vegetation management in these parks is focused on minimizing human-caused impacts on their native plant communities to the extent feasible.
