Remembering Peter Nelson’s advice – pest management for the 21st century

- Wayne Linklater Jun 14, 2018

Peter Nelson is remembered as a founder of modern, 21st Century, pest management in New Zealand. In 1993, reflecting on our nation’s failure to eradicate Australian brushtail possum, rabbits and deer, he wrote: “The aim of Integrated Pest Management (IPM) is to reduce pest damage to tolerable levels by using a variety of techniques, and ultimately also to reduce … Read More

Predator Free by 2050 – a reputational risk to conservation

- Wayne Linklater Mar 16, 2018

I am suspicious when government conservation policy is promoted as a religious war against animals, like Predator-Free 2050 has been (see last month’s post). Instead, why isn’t the rational case for our support being made? I suspect that the religious and war-like language is indicative of flaws in the policy or its implementation (see my last post) In this post, … Read More

Why is Predator-Free 2050 advocated using the language of religion and war?

- Wayne Linklater Feb 01, 2018

The leaders of the Predator-Free movement routinely describe their goal to eradicate rats, stoats and possums from New Zealand by 2050 with religious and militaristic phrases (see Monday’s post). Sir Rob Fenwick (a Director of Predator-Free 2050), for example, described it as a “project born in a leap of faith”, and a “call to arms” by an “ … Read More

Predator Free 2050 – more like a religious war than science-based conservation policy

- Wayne Linklater Jan 29, 2018

One of the leaders of the Predator-Free movement, Sir Rob Fenwick (Chair of the Predator Free New Zealand Trust and a Director of Predator-Free 2050), described Predator-Free 2050 as a “project born in a leap of faith” (Dominion Post). He appears to think the predator-free goal is more like a religion than a science-based conservation project. And, his religion is … Read More

Predator-free is a “mirage” – John Parkes

- Wayne Linklater Jan 08, 2018

Killing predators to reduce their impact is an important part of wildlife conservation in New Zealand. It delivers good outcomes for biodiversity, especially for our birds and reptiles. It does not logically or scientifically follow, however, that attempting to eradicate predators from ALL of New Zealand is also a good idea. Indeed, some scientists think that a national … Read More

Biodiversity conservation in 2100

- Wayne Linklater Nov 10, 2017

This was the theme of today’s panel-public discussion in Old Government Buildings at Victoria University. It was chaired by Kathryn Ryan – host of Radio New Zealand’s Nine-to-noon. Panelists were asked to provide an opening statement that answered the above questions (text box) and described their position. Here is mine. In 2100 people will be an … Read More

We can do better than Predator Free 2050

- Wayne Linklater May 09, 2017

I have established that Predator Free 2050 (PF2050) is not scientifically rational because it can’t be done and carries with it extraordinary scientific, political and social risks for gains that are less than required to address our nation’s environmental and biodiversity challenges. Instead of PF2050 it would be more sensible, lower risk and increase our chances of sustained biodiversity … Read More

Predator Free 2050 is scientifically flawed

- Wayne Linklater May 09, 2017

Predator Free 2050 is good politics but it is scientifically flawed. It can’t be done. Predator-free 2050 was described as a “moon shot” but, actually, its an Andromeda Galaxy shot – unattainable. New Zealand’s, and the world’s, leading experts in animal eradication have already concluded that it is not possible to eradicate introduced mammalian predators from New Zealand. That … Read More

A better conservation science sector is critical… … of itself

- Wayne Linklater Mar 11, 2017

My latest critique of conservation in New Zealand received a largely positive response, especially from others who think empathy with wildlife an important ethic. It was a busy week and so, unfortunately, I haven’t yet responded to all who telephoned and wrote. But the article also received some negative comments, especially from people who identify themselves as conservationist or … Read More

Conservation’s horizon in New Zea la-la land

- Wayne Linklater Jan 30, 2017

Designing ecosystems, reconciliation ecology for conservation The theme for the influential Ecological Society of America’s annual conference last year was “Novel Ecosystems in the Anthropocene”. A novel ecosystem is a human-made habitat and community of plants and animals. Novel ecosystems can be planned, accidental, or caused by poor environmental management that cannot be undone. And Anthropocene describes the current geological age when … Read More
