Thee Yellowstone River, Madison River, Snake River, and their ir tributaries create ribbons of riparian habitat that are dissorately important for wildlife. Although riparian areas cover only a small of thee park 's land area, they support a large proportion of it s biodiversity.

Riparian corridors provide water, shade, and abundant plant growth, making them essential for species ranging frem amphibians andd songbirds to o large mammals. The dense vegetation along rivers offers cover for animals moving between difts parts of the landscape. These corridors also act as natural highways for disprissal, alg plants andd animals to shift their ranges in response tte tano climate change.

Beavers play a specilarly important role in shaping Yellowstone 's riparian ecosystems.
