Twelve plant and animal species are classified as containment control pests in the Marlborough District Council's Regional Pest Management Strategy due to their impacts on economic and ecological values. These species include:
- Nassella tussock (Stipa trichotoma)
- Chilean needle grass (Stipa neesiana)
- White-edged nightshade (Solanum marginatum)
- Kangaroo grass (Themeda triandra)
- Broom (Cytisus scoparius)
- Gorse (Ulex europeaus)
- Nodding thistle (Carduus nutans)
- Ragwort (Senecio jacobaea)
- Contorta pine (Pinus contorta)
- Possums (Trichosurus vulpecula)
- Feral rabbit (Oryctolagus cuniculus)
- Reed sweet grass (Glyceria maxima)
The strategy places the obligation for the control of these pest species on the occupier. The level of control required varies from one pest species to another and, in the case of some species, from one property to another. Objectives include the prevention of any spread of these pest species and the prevention of any increase in their density.
Council carries out inspections to determine if occupiers have carried out the required control work, undertakes enforcement action where required, carries out inspections to monitor for the presence of these pest species on properties surrounding known sites and provides affected occupiers and interested parties with information relating to these pest species.
