Wilding pine control

Control of wilding pines in the Marlborough Sounds is an initiative set up by the Marlborough Sounds Restoration Trust.  Wilding pines are a significant problem in the Sounds, undermining its scenic qualities and threatening native flora and fauna.  In some parts of the Sounds wilding pines are overtaking native plants as the dominant species.

Kaitiaki o Ngahere is among several contractors taking part in this project and carrying out pine control in selected areas of the Sounds.  Pines are located, drilled and injected with herbicide, with specific guidelines about which areas are to be treated depending on land ownership and public safety once the trees have died.  The control work often involves staying in areas accessible only by boat and with limited cell-phone reception.

Project components

  • Using GIS technology to download the positions of mature pine trees onto GPS
  • Developing systems and equipment for safely and efficiently transporting, mixing and applying the required amounts of herbicide for the job
  • Working in remote and challenging locations and environments
  • Ensuring control of all pines (seedlings to mature trees) within the specified area.

The outcome
The results of the project can clearly be seen during a Cook Straight ferry trip – there is great hope for freeing large areas of native bush in the Sounds from pine trees.  The project continues each year with more of the Sounds being brought under the protection of the Marlborough Sounds Restoration Trust.
