Wilding Conifer Rules

Read more about the rules in the Tasman-Nelson Regional Pest Management Plan (updated 2024) relating to wilding and pest conifers.

There are three region wide rules (outside of Operational Areas):

  • A ‘clear land rule’ – that focuses on the eradication of pest conifer seedlings before they can proliferate and spread;
  • A ‘planted forest (wilding conifer spread) rule’ – to manage self-seeded spread from forest plantations onto neighbouring land; and
  • A ‘pest agent conifer rule’ – to manage potential seed sources that may impact neighbouring properties and halt the spread of wilding conifers in general.

And two rules regarding operational areas under management

  • A ‘maintain the gains rule’ - to safeguard prior control and investment; and
  • A ‘good neighbour rule’ (GNR) - for boundary management of pest conifers that prevents an occupier’s inaction on control work impacting their neighbour.

Operational Area is an area currently being managed for the control of wilding conifers under a recognised programme. These areas typically have received taxpayer or ratepayer funding and the rules aim to protect this public investment.  

There are 12 conifer species declared pest conifers in the RPMP, as listed in Table 6. Ten individual species are designated pests in any regional situation while the wilding conifer sub-class of subjects covers two species and their pest designations apply only when they occur in wilding states.

Class of subjects

Wilding conifers

Definition

‘Wilding conifers’ - means any introduced conifer tree, including (but not limited to) any of the species listed in the above table, established by self-seeded means, unless it is located within a forest plantation and does not create any greater risk of wilding conifer spread to adjacent or nearby land than the forest plantation that it is a part of. For the purposes of this definition, a forest plantation is an area of 1 hectare or more of predominantly planted conifer trees.

Species for the purposes of the wilding conifers class description include (but are not limited to):

Douglas fir (Pseudotsuga menziesii)

Radiata pine (Pinus radiata)
