Christchurch weeds



Categories of weeds

Weeds fall into the following categories:

Total control plant pest
A high level of control that aims to eradicate the plant from the region. Species that have been declared total control plant pests can not be sold, propagated or distributed.

Progressive control plant pest
Staged control is aimed at eventual eradication through reduction of propagule sources. Species that have been declared 'progressive control plant pests' can not be sold, propagated or distributed.

Containment control plant pest
Control is aimed at ensuring that the species does not spread in range. Species that have been declared containment control plant pests can not be sold, propagated or distributed.

Surveillance plant pest
No control of existing plants is required, however sale, propagation or distribution of these species is prohibited.

Unwanted organisms
Species that have been declared 'unwanted organisms' can not be sold, propagated or distributed. A Regional Council can also spend money on their control if eradication is feasible.
