Think you found an early Detection Terrestrial plant species?
Invasive plants significantly affect Vermont's ecosystems and economy. Reporting species that are not yet present in Vermont or exist in small numbers but show invasive tendencies can prevent these species from gaining a foothold in our region. Early detection of new infestations increases our ability to slow their spread and potentially eradicate them from affected areas.
Step 1
Review the list of early detection terrestrial plants below and confirm the species that you think you have found. Please note: this list was updated in 2026 to reflect terrestrial plant species listed as Tier I (not yet present in Vermont) and Tier II (limited distribution in Vermont). Giant hogweed has also been included because of its human health risk.
- Kudzu (Tier I)
- Tree-of-heaven (Tier II)
- Black swallow-wort (Tier II)
- Pale swallowwort (Tier II)
- Mile-a-minute (Tier II)
- Porcelain berry (Tier II)
- Wineberry (Tier II)
- Japanese stiltgrass (Tier II)
- Japanese hops (Tier II)
- Amur cork tree (Tier II)
- Giant hogweed (Tier III)

Carefully review common look-a-likes on the species page. There are many native plants that are easily confused with invasive species.
Step 3
Collect one to three clear, identifiable images of the plant species and submit a report at the link below.
Plants designated with an asterisk (*) have been designated as plant pests by the Agency of Agriculture, Food & Markets, and are not allowed in Vermont for import, sale or movement without a state permit.
