NZ predator free by 2050

Prime Minister John Key has announced the government’s goal of New Zealand being predator free by 2050.

“While once the greatest threat to our native wildlife was poaching and deforestation it is now introduced predators,” Mr Key says.

“Rats, possums and stoats kill 25 million of our native birds every year, and prey on other native species such as lizards and, along with the rest of our environment, we must do more to protect them.”

Mr Key says these introduced pests also threaten our economy and primary sector, with their total economic cost estimated at around $3.3 billion a year.

“That’s why we have adopted this goal. Our ambition is that by 2050 every single part of New Zealand will be completely free of rats, stoats and possums.

“This is the most ambitious conservation project attempted anywhere in the world, but we believe if we all work together as a country we can achieve it.”

The Government will lead the effort, by investing an initial $28 million in a new joint venture company called Predator Free New Zealand Limited to drive the programme alongside the private sector.

This funding is on top of the $60 to $80 million already invested in pest control by the government every year and the millions more contributed by local government and the private sector.

Predator Free New Zealand Limited will be responsible for identifying large, high value predator control projects and attracting co-investors to boost their scale and success.

The Government will look to provide funding on a one for two basis – that is for every $2 that local councils and the private sector put in, the Government will contribute another dollar.

“This ambitious project is the latest step in the National-led Government’s commitment to protecting our environment.

“We are committed to its sustainable management and our track record speaks for itself.

“This includes the decision to establish the world’s largest fully protected ocean sanctuary in the Kermadecs, better protection in our territorial sea and our efforts to improve the quality of our fresh waterways.

“We know the goal we have announced today is ambitious but we are ambitious for New Zealand.

“And we know we can do it because we have shown time and again what can be achieved when New Zealanders come together with the ambition, willpower and wherewithal to make things happen.”

This is a BHAG – a Big Hairy Audacious Goal and Conservation Minister Maggie Barry is right when she says it will take a team effort to achieve it.

“New Zealand’s unique native creatures and plants are central to our national identity. They evolved for millions of years in a world without mammals and as a result are extremely vulnerable to introduced predators, which kill around 25 million native birds every year,” Ms Barry says. 

“Now is the time for a concerted long-term nationwide effort to rid ourselves of the introduced rats, stoats and possums that have placed so much of our natural heritage in jeopardy.”

Under the strategy the new government company, Predator Free New Zealand Limited, will sponsor community partnerships and pest eradication efforts around the country.

“By bringing together central and local government, iwi, philanthropists, and community groups, we know that we can tackle large-scale predator free projects in regions around New Zealand,” Ms Barry says.

“Project Taranaki Mounga and Cape to City in Hawke’s Bay are great examples of what’s possible when people join forces to work towards a goal not achievable by any individual alone.”

The Predator Free 2050 Project will combine the resources of lead government agencies the Department of Conservation and the Ministry for Primary Industries to work in partnership with local communities.

Primary Industries Minister Nathan Guy says the goal of a Predator Free New Zealand by 2050 will have major positive impacts for farmers and the wider primary sector.

“Possums and ferrets are the main carriers of bovine TB, which is a very destructive disease for cattle and deer. In this year’s Budget the Government committed $100 million towards combined eradication efforts with industry starting with cattle and deer by 2026,” Mr Guy says. 

“By pooling our resources and working together we can jointly achieve our goals of both eradicating bovine TB, and achieving a predator free New Zealand.”

Not all the technology to make New Zealand predator free yet exists, and the Biological Heritage National Science Challenge will have an important role in developing the science to achieve the predator free goal.

“New Zealand is a world leader in conservation technology and research,” Science and Innovation Minister Steven Joyce says. “The Biological Heritage Challenge has an established network of scientists who are ready and willing to take on the Predator Free Challenge. For the first time technology is starting to make feasible what previously seemed like an unattainable dream.”

Predator Free New Zealand Limited will have a board of directors made up of government, private sector, and scientific players. The board’s job will be to work on each regional project with iwi and community conservation groups and attract $2 of private sector and local government funding for every $1 of government funding. 

Four goals for 2025 have been set for the project:

  • An additional 1 million hectares of land where pests have been suppressed or removed through Predator Free New Zealand partnerships
  • Development of a scientific breakthrough capable of removing at least one small mammalian predator from New Zealand entirely
  • Demonstrate areas of more than 20,000 hectares can be predator free without the use of fences
  • Complete removal of all introduced predators from offshore island nature reserves

“These are ambitious targets in themselves, but ones that we are capable of reaching if we work together,” Ms Barry says. 

“New Zealanders have rightly taken great pride in our conservation efforts to date. If we harness the strength of everyone who is keen to be involved in this project, I believe we will achieve the vision of a Predator Free New Zealand by 2050 and make our landscape a safe haven again for our native taonga species.”

 

Predator free in 34 years is a BHAG but Forest and Bird says it’s possible:

“A country free of predators would allow forests, towns and cities to fill with native bird life such as kiwi, kākāriki (parakeets), pīwakawaka (fantails), tīeke (saddleback), kōkako, and kākā. Other species like tuatara, hihi (stichbirds), toutouwai (robins), insects, and native snails would repopulate forests and other wild places,” says Forest & Bird Advocacy Manager Kevin Hackwell.

“The objective of a predator free country is one that many environmental groups, large and small, have been tirelessly working towards for a long time. However, Forest & Bird intends to look very closely at the detail of how the Government is planning to roll out their vision. For example, if the proposed Predator Free NZ Ltd. company is set up to deliver this programme, what will the role of the Department of Conservation be?”

“Reversing centuries of misguided predator releases and their ongoing devastating effect on our native species and habitats will take commitment, investment, and collaboration, but is entirely achievable by 2050, with the right resources, experts, and framework in place,” says Mr Hackwell. 

“A predator free country will also be of huge value to public health and our agriculture industries which currently spend many millions every year combating waste, contamination, and disease due to pests like rats and possums.”

We spent five days sailing round the Fiordland coast last year, landing occasionally to see native bush much as it would have been when Captain Cook first saw it in 1773. He would have been greeted by bird song but the bush through which we walked was almost silent.

Human and animal predators decimated the bird population and in too many places pests are still winning the battle against the birds.

The Department of Conservation is making a concerted effort to eradicate pests and re-establish species like the kakapo.

That’s not easy on islands and it is even more difficult on the mainland with possums, stoats, ferrets and rats breeding freely and preying on eggs and young birds.

Predator-free fences around bush have been established in several places but the Predator Free New Zealand by 2050 strategy recognises a lot more needs to be done.

It also needs to be done carefully with regard to the whole food chain. Rats prey on mice which prey on birds’ eggs. Eliminating rats would not be enough if that allowed the mouse population to explode.

It will take a lot of money and a lot of work but it will be worth it if it results in burgeoning bird populations with better public and animal health as a bonus from the eradication of pests which wreak havoc on native flora and fauna, and carry diseases.

    The 3 groups, Marsupials, Mustelids and Rodents should all be genetically engineered out of existence in New Zealand. As an isolated location a terminator gene project on these 3 groups has the potential to succeed. Other methods will only ever reduce the problem to un measurable levels. If we do not get the very last one then they will be back!

  2. Andrei says:

    This is the sort of project that ends up producing unintended negative consequences – it could even lead to the extinction of some species it is designed to protect

    Eco systems are semi stable and if you rapidly change them the consequences are unpredictable

    For example consider a species predated upon by rats that feeds upon a certain plant. Now we eliminate the predator and this species now undergoes a population explosion that results in the decimation of its main food source – which leads in turn to a population crash from which the species may not recover

    Chaos theory rules

  3. homepaddock says:

    Andrei – that’s why I said it needs to be done carefully with regard to the whole food chain.

  4. Andrei says:

    It seems like a massive folly to me – an expensive boondoggle, unlikely to succeed and with the potential for ecological catastrophe

  5. Mr E says:

    I have a fair amount of experience of killing Rats in extensive native bush, and I am aware of the rapid rate at which populations can recover from residual populations.

    If we go down this pathway, we need to commit 100%. Failure will result in a monstrous waste of time and wealth.

    Bulaman is correct. I suspect the only way to achieve this goal is to encourage the release of GE material. It is part of what is required for 100% commitment.

    I will watch with interest at Environmentalists climb on board and fall off board with this realisation.

    Without new genetic solutions, I suspect ambitious = unrealistic.

  6. Will says:

    It is possible to achieve on our many small islets, but pretty futile on the mainland. And unnecessary. With the exception of a few poorly adapted specimens, our bird population is fine. Kiwi and kakapo are evolutionary failures, doomed to life in protective custody for the rest of their existence. It’s not clear to me why we attach such value to the stupid things.

    It is not like the country does not have more pressing concerns. Is this some sort of political joke at the Greens’ expense?

  7. Andrei says:

    It is possible to achieve on our many small islets, but pretty futile on the mainland.

    But even then it is only temporary – do you doubt that rats will eventually find their way back to Kapiti – actually they have it is only by Doc being vigilant that it remains rat free

  8. Dave K says:

    Hopefully it is not just limited to terrestrial species but extends to salmonids as well

  9. Andrei says:

    Hopefully it is not just limited to terrestrial species but extends to salmonids as well

    I’m surprised you didn’t add human beings to your wish list as well Dave Kennedy

  10. Mr E says:

    Andrei,
    Dave Kennedy? Presumptuous.

  11. Dave Kennedy says:

    Dave K is not me😉 I support this policy and Ele’s post. However as DoCs funding has been cut severely over the past 7 years it may need a boost to ensure we have enough resources and people on the ground. We can’t just rely on dumps of 1080.

    Other estimates have put the total cost at $9 billion. That’s quite a commitment. However the more efforts we make at preserving our natural environments the more attractive we’ll be to tourists. Perhaps more money can be generated from tourists to support the environments that they want to experience.

    Based on 2015 visitor numbers (3 million) a conservation levy of $25 could earn around $4 billion by 2050.

  12. Paranormal says:

    My concern is this just doesn’t open the 1080 aerial top dressing bomb bay doors.

    I’m all for poisoning possums and other pests, but from ground bait stations. Aerial spraying leaves too much to error. A neighbouring farmer has now lost a number of deer and a dog to 1080. I’m sure we’ll learn that our fisheries have been harmed by 1080 poison along with other unforeseen consequences.

  13. Freddy says:

    There is not the slightest hope of making any impact with bait station ground control, you only need to spent two minutes in our bush to appreciate the impossibility of it. As an example, the NZ Govt have been throwing the kitchen sink at Deer since the 1930′, the population continued to expand dispite this until the 1960′ when Venison became so valuable every man and his dog were going bush to make a quick buck, dispite the huge profits to be made commercial harvesting deer the population only receded to a stable level, it was never in any risk of being wiped out.
    Aerial 1080 drops are the only hope of holding our ground until something better comes along. It’s our version of a finger in the dyke.

  14. Name Withheld says:

    However the more efforts we make at preserving our natural environments the more attractive we’ll be to tourists.

    Removing the salmonids is a little counter-productive to this aim, don’t you think?

  15. Dave Kennedy says:

    I agree with you Freddy for remote areas, but around the fringes and in areas close to farms and people I think there are risks with 1080 use. Already a significant difference is being made with new trapping systems in accessible places.

    NW, that wasn’t my comment, but I do see the potential value in having some streams free of Salmonids and whitebaiting so that native fish species can thrive.

  16. TraceyS says:

    Because there are no risks with trapping eh Dave?

    When will you learn that there are risks with everything!

  17. Paranormal says:

    It’s interesting NZ didn’t have a possum problem until after the removal of the bounty. A friend at University put himself through on the back of his trap line over Mount Pirongia. That work is just not being done now.

    Have you seen that terrain Freddy? There is no terrain in the country that hunters don’t visit. And yes I’ve been into a lot of those places too. My favourites being the Kaimanawas and Kawekas.

    The solution is to go back to a system where locals are incentivised to undertake pest control. And you know what – some of those conservation millions can play a dual role – helping solve employment issues in places like the East Cape and Westland.

    As for deer, we don’t need to eradicate them. They have taken the ecological niche that was filled by the Moa. Don’t believe me – then why is the lancewood like it is?
