A new high-tech mapping system developed by Land Information NZ will give authorities fighting the spread of wilding pines their first complete picture of infestations nationwide.
The pines are a major threat to ecosystems, native landscapes and farms.
They are estimated to cover more than two million hectares and are spreading at a rate of 5% a year.
Land Information Minister Mark Mitchell says the new wilding conifer information system will underpin the control programme run by MPI, the Department of Conservation and forestry, farming and community groups.
The web-based mapping system captures real-time information and comes with a mobile app that authorities can use. NZN
