The National Wilding Conifer Management Strategy has been released by the Ministry for Primary Industries just before Christmas and you can download it by clicking here

strategy front

Wilding Conifers displace native vegetation, change ecosystems, reduce available grazing land, limit future land use options, visually change landscapes, can affect water quantity in water sensitive catchments, and can result in damaging wild fires.

Approximately 1.7 million hectares, almost 6% of New Zealand, have already been affected to some extent by these unwanted trees.

Wilding conifers are continuing to increase in area at an average compounding rate of approximately 5-6% per year. At current infestation levels this equates to approx 90,000 hectares each year becoming infested.

Without effective control this initial infestation gets progressively denser until it is solid wilding conifer forest.

In March 2013 a working group was established to develop a strategy for the management of wilding conifers in New Zealand - The New Zealand Wilding Conifer Management Strategy 2015 -2030. 

Membership of the working group consists of key stakeholders including the forestry and farming industries, regional and district councils, DOC, LINZ, NZDF, researchers and community trusts.

The strategy proposes a range of actions to improve the efficiency and effectiveness of wilding conifer management.

MPI is currently leading a process to decide on the next-steps to implement the strategy.

Annual Group Meeting in Rotorua 7-8th April 2014

The 2014 annual meeting of the National Wilding Conifer Management Group was held in conjunction with the North Island Wilding Conifer Group bi-annual meeting at the Scion Campus, Rotorua. Again over 30 people from across the country with a strong contingency from the North Island attended the one day meeting and also joined the fieldtrip that covered wilding conifer areas in the Central North Island. A particular high point was the visit to the Waiouru NZ Army area - not only a "training" ground for the army but for wilding conifer control teams too.

After a short introduction and the Annual General Meeting of the Groups (draft minutes can be found here) at the start of the meeting, the day was filled with information and updates related to wilding conifer management from the regions and affected areas (representatives gave a short overview of their actions) and wilding conifer related research.

Presentations covered the progress of the WCG in Queenstown (click here for the presentation), updates on the work that Horizon is doing and a update on the development of the North Island Initiative -Nature Central-. Brian Richardson General Manager for Forestry Science gave an introduction to Scion and talked about Scions long history in wilding conifer management (early control at Waiouru, click here for the presentation). Kit Richards provided a forest management perspective on forest certification (Forest Stewardship Council) as this requires now the monitoring and management of spread from plantations (click here for presentation). Thomas Paul gave an overview of this years progress on the SFF work (click here) and touched briefly on the possible way forward in regards to mapping of wilding areas on a national scale and how this data could be made available via a LINZ Initiative (David Mole) (click here). Stefan Gous (Scion) and Pete Raal (DoC) gave an update on aerial and ground based control systems and chemicals (click here). Armin Wagner talked about Scion's research in Genetics of pines that might lead someday to the development of trees that do not spread (click here). Veronica Clifford, researcher with the Scion Fire Team, gave a presentation on wildings and fire, understanding the impact of wildings on fire risk in NZ and fire as a potential control tool (click here). Duane Peltzer from Landcare Research had the last word, giving a good overview of their co-invasion work and future directions of their research in the weeds and wildings space (click here).


Overall the workshop was well received and the field-trip provided a good overview of the situation in the Central North Island. Great inroads have been made controlling Lodgepole pine, but still a lot of work needs to be done to reduce wilding "pressure" on landscape and biodiversity values in the Central North Island.

Report on the status of wilding conifers in New Zealand released

The long awaited report on the status of wilding conifers has been released by the Ministry of Primary Industries (MPI) which will provide a very good overview over the wilding conifer situation in New Zealand. The report has been developed over the last year by Victoria Froude from Pacific Eco logic commissioned by MPI in April 2011 to develop a report with the purpose to bring together information to address the historical factors, the current state and the impacts of wilding conifers but also the legislation and policy and the current management and control of wilding conifers. Logically the report also identified barriers to manage and control and the current and future risks associated with wilding spread and land use issues. In addition the report informs the reader on current research and potential opportunities and by including of a number of case studies highlight some of the ecological problems arising from wildings.

This overview led to a number of recommendations in the report to improve and guide future action and to assist MPI to determine their future role with respect to wilding conifers under the Pest Management: National Plan of Action (PMNPA) and to identify opportunities for improving efficiency and effectiveness of wilding conifer management in New Zealand.

As the report was prepared and reviewed, a wide range of stakeholders had the opportunity to contribute their perspectives, ideas and information and it gave many stakeholders also a chance to confirm or question collated information or add additional and alternative information. This allowed the identification of topics and issues where consensus exists and the identification of ways how parties could work together to improve policy and management systems affecting wilding conifer management. The WCMG and most of its members were actively involved in the development of this report. The WCMG could also provide the appropriate stakeholder forum for the preparation of the non-statutory national strategy for wilding conifer management.


The first two key recommendations from this report, that have been signed off by the Minister so far are:


  • That a non-statutory national strategy be prepared for wilding conifer management. The issues and options in the report provide a framework for the strategy and
  • That the Ministry of Primary Industries be the lead agency for preparing this strategy.



The main report (a real “door-stopper” of 207 pages) can be downloaded by clicking here.

A summary report including the key-components of the primary report and an evaluation of current and potential wilding conifer management can be downloaded by clicking here.

A number of appendices (Distribution maps from the Department of Conservation) that a supplementary information to the report are available under Maps & Models
