3. Mistaken Identity

Think you found an early Detection plant species?

Invasive plants have a major impact on Vermont's natural ecosystems. Of greatest concern are species not yet found in Vermont, or species that are present in low numbers but exhibit invasive behavior. The sooner we find new infestations, the better our chances of slowing their spread to other areas, and of eradicating it where it has been detected.

  1. Check the List of Early Detection Plants below for early detection species and confirm the species identification that you think you have found.
  2. Submit a photo.
