The Maine Department of Agriculture Conservation and Forestry (DACF) has recently verified the first known occurrence of mile-a-minute weed (Persicaria perfoliata) in Maine. This fast-growing invasive vine, native to India, Asia, and the Philippine Islands, poses a significant threat to nurseries, Christmas tree farms, reforestation projects, and restoration areas, as it can smother young plants and trees under its dense growth.

Invasive species like mile-a-minute weed have the potential to cause severe harm to Maine's environment and economy. As part of our commitment to controlling and eradicating this invasive plant, the DACF urges the public to report any potential sightings promptly. If you encounter a vine resembling mile-a-minute weed, please visit the Maine Natural Areas webpage for identification information. If the plant matches the description, we encourage you to take photos, note the location, and report the finding via email to Invasives.MNAP@maine.gov or call (207) 287-7545.

MIPN synthesized recent research on garlic mustard and developed recommendations to help managers navigate sometimes-conflicting information about whether and how to prioritize management of this species. This 12 page guide includes a decision-support tree and a box discussion of best practices for volunteer pull events.

Garlic mustard (Alliaria petiolate) is a highly destructive invader in North America. As well as hindering the survival of native plants, it poses a particular threat to the survival of the rare West Virginia white butterfly (Pieris virginiensis).
