It can be a legal requirement to report certain weeds, particularly if they have been listed as a high priority weed in your state or territory. All jurisdictions have lists of weeds that are high priorities and should or must be reported. Legislation and terminology differs between the states and territories, but these weeds are often termed ‘notifiable’, ‘prohibited’, ‘reportable’ or ‘alert’ weeds. Typically, these weeds are either not known to occur in the state or territory, or are in the very early stages of establishment, and would have a significant impact if allowed to spread.
Some weeds can also be reported at the national, regional or local government level.
