Control in my area

The linked maps below show where wilding conifers are spreading, and where the National Conifer Control Programme is currently operating.

Programme control areas

To support the wider Programme, Land Information New Zealand (LINZ) has developed a web-based mapping and monitoring tool which provides a complete and consistent picture of where wilding conifer spread is present in New Zealand. You can use this tool to report an infestation that we don't yet have on our maps, or to learn about infestations in your area.

There is also a mobile App that LINZ have developed for Programme field workers - download the appropriate App here.

Community groups

There are groups helping to control wilding conifers throughout New Zealand – visit our Community Group page to join a group in your area.

Land holders and managing spread

If you’re a Land holder, you can also help by controlling conifers and minimising spread of pines from your property.

If left unmanaged, scattered trees can turn into dense forest and costs of control escalate rapidly. So it pays to control any scattered trees on your place early and remove the seed sources, if possible.

The usual method is to control seedlings and outlying trees first, and work back to the original seed source. Monitoring and ongoing management is needed twice in the following 5-6 years after initial control, as some wilding conifer seeds remain viable for this long.

Some re-infestations are hand weeded, while in other situations ongoing management can be achieved by mob-grazing and fertilising to encourage grasses that compete with wildings. Work with neighbours to control wilding conifers that have spread across property boundaries.

Discourage wilding conifer spread by:

  • selecting carefully which conifer species you plant and where
  • removing wilding conifer saplings that have established outside planted areas, before they develop seed cones

Be a good neighbour

Regional councils' Regional Pest Management Plans may list wilding conifers as pest species, and have rules that require land holders to control these plants. Good neighbour rules may mean it’s the landowner’s responsibility to remove these plants from their property and prevent them from spreading into neighbouring properties.

What if my neighbour isn’t controlling their pest trees?

If the plants are listed as pest plants for your area, contact your regional council for help. Your neighbour may be required to contribute to the removal of wilding conifers from your land.

If the plants aren’t listed as a pest plant for your area, then discuss the problem with your neighbour.
