Why New Zealand needed a strategy for wilding conifer managementIn 2014, despite the collective efforts of central government, local government, and land holders, large areas of New Zealand were affected by wilding conifers and they were spreading by more than 5 percent - around 90,000 hectares - each year. If left unchecked, these tree weeds would cover 20 percent of New Zealand by 2030. The New Zealand Wilding Conifer Management Strategy 2015-2030 was developed in response to this threat, and the National Wilding Conifer Control Programme was established in 2016 to deliver on the aims of the strategy. The strategy balances the good and bad of conifers - minimising the negative impacts of wilding conifers, while keeping beneficial conifer plantings. It also highlights that wilding conifer management is a complex and long-term undertaking. |

In the right place, conifer trees have benefits for New Zealand. They provide timber, store carbon, decrease erosion, filter soil nutrients, improve water quality, and provide shelter and shade for stock. In the wrong place they are a major threat: to our ecosystems, landscape and farms. They out-compete native plants and animals, remove up to 40% of water from a catchment, limit productive land use options on high country farms and severely alter natural landscapes. Wilding conifers may also increase the risk of wild fires and harbour disease. Without decisive action, preventing them from spreading further would soon be beyond our grasp.
The Strategy was developed by Biosecurity New Zealand (part of the Ministry for Primary Industries) and a working group with a range of perspectives. This work was done in association with the National Wilding Conifer Management Group (now the Wilding Pine Network).
