In April 2002, the Vermont Department of Agriculture, Food & Markets adopted a plant quarantine rule in order to regulate the importation, movement, sale, possession, cultivation, and/or distribution of certain invasive plants. The rule creates two quarantine categories.

Class A species are not yet known to occur in Vermont and are all species on the federal noxious weed list. The movement, importation, sale, possession, cultivation, and/ or distribution of Class A plants is prohibited.
Class B species occur in Vermont and pose a serious threat to the state. The rule prohibits the movement, sale, and/ or distribution of Class B species.
