New - The Regional Pest Management Strategy is under review Find out more about the review.

In Marlborough, we are faced with ongoing control of many pest species that were the result of historic introductions, for example, Chilean needlegrass. Other species such as the invasive sea squirt, Styela clava in the waters of the Picton Marina, are more recent arrivals, which our team are involved with.

The Biosecurity team currently consists of five team members who monitor, regulate and control pests (both animal and plant) that are within the Regional Pest Management Strategy (RPMS).

A large part of the Biosecurity team's job is to conduct compliance inspections on farm properties for pests under the RPMS to ensure landholders control pests on their properties to a satisfactory level.

Another part of the Biosecurity team's role is to eradicate pests classed as Total Control pests in the RPMS; these are pests that are found in low number in Marlborough but have the potential to become serious invasive issues if left, for example Chinese Pennisetum.

We also have a number of surveillance pests which the Biosecurity team survey the area for to gain more information on their distribution and assess potential issues for the region in the future, for example, Argentine ants.

Another important role for the Biosecurity team is to advise and provide awareness of biosecurity issues and methods to control and prevent the spread of pests.

If you find a plant and are not sure what species it is, the Landcare Research plant ID is a great resource to help you. If you are still unsure what it may be, contact the Biosecurity team.
