Ecological Threat Several species are considered invasive in the United States and distinguishing the species can often be difficult. Tamarix aphylla invades streambanks, sandbars, lake margins, wetlands, moist rangelands, and saline environments. It can crowd out native riparian species, diminish early successional habitat, and reduce water tables and interferes with hydrologic process. Tamarix aphylla is native to Eurasia and Africa and was introduced into the western United States as an ornamental in the early 1800s. It occurs throughout the western and central United States, but is most problematic in the Southwest.
