Physiognomy and Structure: This vegetation typically forms shrubby thickets. Shrub density often is such that there is virtually no herbaceous layer development.

Floristics: Examples may be dominated by Ligustrum sinense, Tamarix spp., and other exotic shrubs.

Dynamics:  These are dominated by shrubs which benefit from canopy disturbance and, for instance, may increase when the canopy is opened from wind or logging activities.
Environmental Description:  These are bottomland, riparian, wetland and coastal areas which are dominated by exotic shrubs. Tamarix spp. are found along the upper tidal zone of brackish and salt marshes and along the upland edge of bays along the Gulf and Atlantic coasts of North America, especially in areas of dredge spoil.
Geographic Range: This alliance occurs in warm temperate areas of the southern United States, and the Mexican state of Tamaulipas.
