The North American Black Locust tree, a continental native tree, of the legume family, is considered invasive within North America, in New York and Connecticut and Massachusetts and the rest of New England, mid-west prairie areas, and the west of the continent.
Its original range, before European arrival, is believed to be in Appalachian Mountains, Pennsylvania to Georgia, and the Ozarks.
It has been used as a pioneer species to restore treeless land in other continents, including Europe, Asia and Africa and Australia. Spain has used them to restart forest in desertified areas, for example.
