Wetlands, Marshes and Swamps
Wetlands, marshes, and swamps are abundant in Grand Teton National Park. These areas are fed by numerous mountain streams, springs, or seeps and provide vital habitat for a wide variety of plants and animals. Vegetation such as pond lilies, willows, and cattails supply wildlife with food and shelter.
