The riparian ecosystem runs through the montane, subalpine, and alpine tundra zones and creates a foundation for life, especially for species that thrive next to streams, rivers, and lakes.[74] The headwaters of the Colorado River, which provides water to many of the southwestern states, are located on the west side of the park. The Fall River, Cache la Poudre River and Big Thompson Rivers are located on the east side of the park. Just like the other ecosystems in the park, the riparian zone is affected by the climatic variables of temperature, precipitation, and elevation. Generally, riparian zones in valleys will have cooler temperatures than communities located on slopes and ridge tops. Depending on elevation, a riparian zone may have more or less precipitation than other riparian zones in the park, with the difference creating a shift in the types of plants and animals found in a specific zone.[75]
