USDA Officials have determined
that certain species not native to the U.S. are
at risk of becoming invasive should they enter this country.
As part of its effort to prevent the introduction of
invasive or potentially invasive weeds, the USDA maintains
an official Federal
Noxious Weed List. Many taxa
on this list are currently serious weeds elsewhere
in the world, and about two-thirds of the taxa are
currently found in the U.S.
