LINZ works to control terrestrial weeds and wilding trees on LINZ-administered Crown land.
Here you can find out more about current control programmes for terrestrial weeds and wilding trees, the control methods used and the implementation of control programmes.
Control programmes
LINZ is currently undertaking control programmes to target terrestrial weeds and wilding trees. Target species include: wilding conifers, in particular Pinus contorta, as well as gorse, broom, Old Man's Beard, nasella tussock, briar rose and other pest plant species.
You can download the Pest Plant Control Programme 2011-2012 (PDF 186KB).
LINZ is working with regional councils to control the spread of wilding conifers in the South Island. Wilding conifers such as Pinus contorta, Pinus mugo, Pinus nigra and larch pose a significant threat to the production, biodiversity and landscape values of the South Island regions.
Control methods
Wilding trees and shrubs are controlled using a combination of techniques such as mechanical (using axes, chainsaws), hand weeding or by herbicide spraying. The technique utilised depends on the nature of the terrain, accessibility and the resilience of certain species to herbicides.
Implementation of control programmes
Public consultation
The control method used for tree and shrub control is decided after consultation with interested parties such as Department of Conservation, adjacent landowners, regional councils and local interest and user groups.
Public notices
Before a control programme takes place, the public are informed via local newspaper and radio notices, and signs.
