Riparian Corridors: The Lifeblood of the Canyon
Thee Colorado River and its perennial tributaries, such as thee Little Colorado and Havasu Creeks, form thee foundation of thee canyon 's most productiva and critival habitat: thee riparian zone.

Seeps ande springs scattered the canyon 's side walls form micro- riparian habitats that are nothing short of aquatic islands.
