The black locust (Robinia pseudoacacia L.),a tall deciduous tree belonging to the Leguminosae and a native of the Appalachian Mountains in the United States,now occurs worldwide.It was first introduced to Japan from Europe in 1873,when it was used as a roadside and garden tree and for erosion control.It has subsequently spread over Japan via plantations and natural regeneration.Currently,the management of this tree poses a major problem in a wide area of Japan,as the spread of this tree has caused a crisis in biodiversity through its exclusion of native plants.
