A serious problem in New England where it can form thick stands that eliminate all native understory plants. Although it was initially thought to invade mostly disturbed sites (old fields, roadsides, etc.) it is now known to invade high quality habitats as well, including closed canopy forests. Recent studies have doucmented serious ecosytem impacts as well, including changes in soil nitrate concentrations which may permit the invasion of other weedy or exotic species or hinder the restoration of the native flora even if B. thunbergii were successfully eradicated. Also a problem weed in the upper Midwest, and some areas of the southeastern U.S (NatureServe 2007).
