Upper Santa Ana River
Riparian Species

Riparian habitat develops along the margins of the stream channels and serves as the interface between terrestrial and aquatic systems. Riparian vegetation structure consists of shrubs, woodlands, and forest, with the width of the riparian zone dependent on channel pattern, slope, and type. In the Planning Area, several Covered Species of birds nest and forage in the riparian habitat, including the Least Bell’s Vireo, Southwestern Willow Flycatcher, and Yellow-billed Cuckoo, and Yellow-breasted Chat.
