Riparian Habitat

Along the banks of Santa Ysabel Creek and other small creeks throughout the watershed is riparian habitat (a streamside freshwater wetland). The fairly consistent water source (above and below ground) supports a dense thicket of vegetation that’s typically taller and lusher than those in the drier chaparral or coastal sage scrub habitats. Flowing streams and drainages create washes that support trees and smaller herb-like plants. Cool, shaded, and wet riparian habitat attracts many species. Noteworthy species that make this habitat their home are the Least Bell’s Vireo, Southwestern Willow Flycatcher, and Arroyo Southwestern Toad.
