The Ministry for Primary Industries oversees a national wilding conifer programme divided into 79 management units, but less than half are currently active due to lack of funding.
Although the programme had received $140 million from the government and $20 million from partners since 2016, the current financial situation is dire. Boffa Miskell biosecurity consultant Sian Reynolds highlighted that only 31 units are being managed this season, leaving 42 units with no funding at all.
The dwindling budget has forced the programme back to a baseline of just $10 million per year, while at least $40 million annually is needed for effective wilding conifer control.
It is estimated that deferred control could increase costs by about 30% each year, making the need for adequate funding critical.
Reynolds emphasized the importance of investing in wilding conifer control now to prevent a major issue in the future. With about 10 conifer species classified as wildings, including douglas fir and contorta pine, the spread of these invasive trees could have significant consequences for the environment and agriculture.
Boffa Miskell has been managing the wilding conifer programme at Molesworth and Muller stations, investing approximately $12 million in controlling the infestations in the area. However, recent funding cuts have led to the abandonment of control efforts in certain high-risk areas, posing a threat to the natural landscape and farming activities.
Despite the challenges, there have been successful examples of wilding conifer control in areas like Flock Hill station and Craigieburn, showcasing the importance of proactive management.
North Canterbury farmer Hamish Roxburgh highlighted the need for comprehensive land management strategies post-removal of wilding conifers to prevent reinfestation. He emphasized the effectiveness of controlled burning as a method of eradication, but noted the resistance faced from some quarters due to environmental concerns.
Overall, the issue of wilding conifers requires a multi-faceted approach involving adequate funding, effective control measures, and sustainable land management practices to safeguard New Zealand’s high country landscapes.
