Global Range: Schinus is a native of Argentina, Paraguay and Brazil. In its native range it is a sparse species and never attains the dominance that it acquires in some of the places where it is a naturalized exotic. Schinus has been introduced and become successfully naturalized in more than 20 countries and its range now forms 2 circum-global belts. In the U.S., Schinus (either S. molle or S. terebinthifolius) is found in southern Arizona, southern California, Texas, Louisiana, Hawaii, and the Commonwealth of Puerto Rico, as well as the Bahamas. Schinus was intentionally introduced into south Florida for use as an ornamental in 1891 although there is evidence of its presence 50 years earlier (Gogue et al. 1974). It is still planted in this capacity in California, Texas and Louisiana. In Florida, as in Hawaii, Bermuda, the Bahamas, and more recently in Australia, Schinus has become an an aggressive, rapidly spreading weed that displaces native vegetation (Bennett et al. 1988). This plant is a fast- growing aggressive shrub. It makes a dense canopy, shading out most vegetation it contacts (Ewel et al. 1982).
