Correctly monitoring and mapping infestations and control operations helps to ensure that wilding conifers don’t re-infest a controlled site.
Controlled areas need to be monitored regularly, as conifer seeds in or on the ground are viable for up to 6 years. Check controlled sites after 2-3 years and hand-pull any seedlings that have sprouted. Repeat this 2-3 years later. For more information on Control methods, follow the quick link at the bottom of this page.
Generally, if the site is clear of wildings after 6 years from its original control, the operation will be complete. Although if there is a seed source that cannot be removed, then control will be ongoing.
The LINZ - Wilding conifer information system has been developed by Land Information New Zealand (LINZ) to support the National Wilding Conifer Control Programme. The tool is well-suited for larger landholders and stakeholders involved in control efforts. They use it to:
Another support for dealing with larger infestations is a standardised 'good-practice' method of post-control monitoring - something we are working to develop.
