Weeds in this category |
Prevention |
To prevent the weed species arriving and establishing in the region. |
High risk species not known to be present in the region. |
Eradication |
To permanently remove the species and its propagules from the region. |
Species present in the region to a limited extent. |
Containment |
To prevent the ongoing spread of the species in all or part of the region. |
Species have a very high weed risk and very high feasibility of coordinated control. |
Asset Protection |
To prevent the spread of the species to key sites/assets of high economic, environmental and/or social value or to reduce impact on these values if spread has already occurred. |

State Management Priority – Control Zones

A person who deals with a carrier of boneseed must ensure the plant (and any seed and propagules) is not moved from the land; and immediately notify the local control authority of the presence of the plant.
