The following 336 weeds have been included in WeedScan because they are considered a priority in one or more states or territories in Australia. This means that these weeds have the potential to be very damaging but are either not yet present, are still becoming established or may not have reached their full potential distribution.
Weed names in bold have not yet been included in the weed matching model but they are slated to be included in future models.
