US draft Federal noxious weed lists


USDA-APHIS (US) has a noxious weed program which is designed to prevent the introduction into the United States of non-indigenous invasive plants and to prevent the spread of newly introduced invasive plants within the United States. On its web site, a draft list (2000-08-09) of noxious weeds is available. In a draft action plan for the noxious weeds program, this list has been further worked (2002-01), and plant species have been separated into four lists: federal noxious weeds, not in US (A1), federal noxious weeds, introduced (A2), regulated non-quarantine weeds (C) and a list of non-regulated weeds of interest to APHIS.
