Kudzu is also from Asia.....developing....
Kudzu was brought into the southeastern states in the early 1930s by the USDA Soil Erosion Service (soon renamed Soil Conservation Service), to help reduce rampant erosion of roadside banks and raw gully surfaces where no native plant species cold gain a foothold on extremely erodible, highly infertile soil surfaces. Being a very aggressive and competitive member of the plant world, kudzu soon exploited and conquered areas where it was not wanted, invaded woodlands and completely covers native trees. As you drive the rural highways and byways of Mississippi you can easily spot trees covered with kudzu vines. My guess is that it crowds out more desirable and commercially useful woodland species.
In other parts of the U.S.A. i.e., Corn Belt states, other non-native, highly invasive/competitive plants introduced to America by the USDA in the 1930s to help control erosion and/or provide wildlife habitat can be found spreading (and achieving dominance) in areas where they were not wanted. Reed Canary grass and multiflora rose are two such plants.
