The Weed Commissioner for the Town of Vernon has made determinations about which of these plants should have considerations for the Town. Proposed Town of Vernon status of plants: Yes - indicates that this plant should hold a status of Noxious, Nuisance, or Restricted weed in the Town. Maybe - indicates that this plant should not hold a status of Noxious, Nuisance, or Restricted weed in the Town at this time. But the plant is worthy of concern and future change in status is possible. No - indicates that this plant should not hold a status of Noxious, Nuisance, or Restricted weed in the Town. There is no merit for status. (blank) - indicates that this plant has not been throughly considered due to an ambiguous common name referencing this plant. Once the scientific name is agreed upon, and the identity of this plant becomes known, then the plant may be worthy of through review.
