Biotic Community: Lower Colorado River: Sonoran Desert

The name of my biotic community is the Lower Colorado River Subdivision of the Sonoran Desert. It is located specifically downtown Phoenix area but covers a much wider area all together. This community is dominated by low shrubs, primarily creosote bush (L. tridentate) and white bursage (Ambrosia dumosa).  These shrubs don’t require much water to survive but are most common by drainage ways. These plants can live up to two years without water at all. The plants have very shallow roots to intercept any water that falls on the soil.
