RESEARCH: An Ecologist & a Biological Sciences Professor propose an alternative to Predator Free 2050: “based on 3 flawed assumptions … it is badly designed & unachievable” they say

A research collaboration is proposing an alternative to Predator Free 2050, calling the current policy “badly designed and unachievable”.

16 July 2018

The research says the Predator Free 2050 policy is based on three flawed assumptions — that predator extermination is the best way to protect biodiversity, that we need to eradicate every stoat, rat and possum to protect biodiversity, and that complete eradication of predators is possible. This research collaboration was undertaken by Associate Professor Wayne Linklater from Victoria University of Wellington’s School of Biological Sciences and ecologist Dr Jamie Steer, who is also a Senior Biodiversity Advisor at the Greater Wellington Regional Council.

“None of these assumptions are true,” says Associate Professor Linklater. “Complete eradication of predators is technologically impossible, and biodiversity is affected more in some places by habitat decline and plant eaters than it is by predators.”

But perhaps one of the biggest issues with Predator Free 2050 is it requires eliminating select predators from complex communities of other plants, animals and humans, he says.

“This will likely lead to negative social and ecological outcomes. Eradicating some predators will cause populations of other introduced animals to erupt. Many people also have valid concerns about the safety and cruelty of predator control methods, and the policy fails to take into account Māori views on predator management as well, particularly on Māori lands.”

Predator Free 2050 could also lead to reduced public and government support for future conservation policies, says Associate Professor Linklater.

Two academics have hit out at the Government’s Predator Free 2050 goal, calling it “badly designed and unachievable”

From News Hub

They say the plan could lead to a decline in public support for conservation policy, because it’s an “impossible” target destined for “inevitable failure”.

The plan was announced by former Prime Minister John Key in 2016, and Conservation Minister Eugenie Sage has previously said it needed a “reality check”.

Victoria University School of Biological Sciences associate professor Wayne Linklater and ecologist Dr Jamie Steer said their research shows the plan is based on flawed assumptions.

Those assumptions are:

  • Predator extermination is the best way to protect biodiversity
  • The country needs to eradicate every stoat, rat and possum to protect biodiversity
  • A complete eradication of predators is possible

“None of these assumptions are true,” Mr Linklater said.

“Complete eradication of predators is technologically impossible, and biodiversity is affected more in some places by habitat decline and plant eaters than it is by predators.”

He said eliminating select predators from complex communities of plants, animals, and humans was likely to be harmful, causing populations of other introduced animals to erupt.
