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.

It is very common to see wildlife browsing in these areas where the water meets the land. Oxbow Bend and Willow Flats provide excellent habitat for moose that graze on willow and other aquatic vegetation.

Beyond providing habitat for plants and animals, wetlands help filter water and temper flood waters. Whether they are created by a beaver's dam at Schwabacher's Landing or are naturally occuring along the Snake, wetlands are an integral component of the ecosystem.
