Notification of possum control using aerially applied toxin



Landowners and other interested parties are advised that Vector Free Marlborough Limited (VFML) will be commencing aerial application of bait containing the toxin Sodium fluoroacetate (1080) to the Stormy Ridge and Karamea Bluff blocks in the northern Buller, from daylight on Wednesday 2/05/18. The aerial application of non-toxic prefeed bait to these blocks was completed in late March.

The operation is being carried on behalf of OSPRI, to keep possum numbers under control to prevent spread of tuberculosis (TB) to livestock. It is important to keep possum numbers low as we work towards eradicating TB from New Zealand over the long term.

Description of control area

The control area is located in the northern Buller. It is situated between the north bank of the Ngakawau River and the south bank of the Kohaihai River, and takes in approximately 32,310 hectares of forest including significant tracts of Department of Conservation managed land, as well as some private land. Maps of the control area may be obtained from the VectorFree website or by contacting us using the details below.

Operation date

The application of toxin will begin from daylight on 2/05/18 and is expected to take several days to complete. Commencement and completion of the operation are subject to weather, and if conditions are unsuitable it will begin on the first fine day thereafter. In the event of an extended delay occurring, further notification will be provided. People intending to venture into the control area are encouraged to contact VFML for up-to-date advice.

Poisoning methods, poison used and nature of poison

• Sodium fluoroacetate (1080) in the form of a cereal pellet with a toxic loading of 0.15%, approximately 30mm long, cinnamon-lured and dyed green. 1080 pellets will be aerially applied onto the ground.

General warning

The public are reminded of the danger that toxic baits and possum carcasses pose, particularly to children and dogs.

• Follow advice stated on poison warning signs.

• Do not touch poison baits.

• Do not touch poisoned possum carcasses.

• Children must be kept under strict supervision in the control area.

• Keep pets under supervision; do not let dogs eat poisoned carcasses.

Game animals should not be sold or taken for eating from within or adjacent to this area until the area is declared clear of pesticides.

Dogs must be kept under strict control at all times and not have access to, or be taken into, the control area, as they are particularly susceptible to harm from contact with 1080 baits and poisoned carcasses. The risk that poisoned carcasses pose to dogs may extend downstream of the control area.

Warning signs will be erected at all main public entry points, and the public are reminded that it is an offence to remove any of these signs. Please follow the instructions stated on the signs.
