Vermont's Noxious Weed Quarantine

In 2003 the Vermont Department of Agriculture, Food & Markets passed the Noxious Weed Quarantine rule to regulate the importation, movement, sale, possession, cultivation and distribution of certain invasive plants. The plants found on the Noxious Weed Quarantine are either currently negatively affecting Vermont or could in the future pose a serious threat to Vermont's natural and recreational areas.

Vermont's Invasive Plant Watch List

After the establishment of the Noxious Weed Quarantine, the Vermont Invasive Exotic Plant Committee created an invasive plant watch list to monitor other non-native plants that have the potential to become invasive in Vermont. This list has no legal implications but instead encourages people to observe, assess and report where these species occur and how rapidly they may be spreading.
