Educate and Control
These weeds are present in the County, pose a significant threat, and are deemed controllable or eradicable. Some of these weeds are prevalent in large infestations in the County. These large populations should be controlled or suppressed to prevent further spread.
These weeds are not yet known in the County but are likely to move in OR have been found only in small, scattered, localized infestations AND should be eradicated immediately upon discovery. Notification will occur immediately upon proper identification by MCWCD staff.
