Hunters Back Scientists Criticism of “Impossible” Predator Free 2050 Dream
The Sporting Hunters’ Outdoor Trust has condemned the much vaunted Predator Free 2050 campaign as unrealistic,
unattainable and destructive ecologically.
The Trust’s spokesman Laurie Collins of West Coast said the Department of Conservation’s obsession with
eradicating predators flew in the face of biological reality.
“Predators in a balanced ecosystem are an essential part of the established food chain,” he said.
Laurie Collin’s comment was in support of two scientists Associate Professor Wayne Linklater from Victoria
University of Wellington’s School of Biological Sciences and ecologist Dr Jamie Steer, a Senior Biodiversity Advisor at
the Greater Wellington Regional Council who recently said Predator Free 2050 was based on three flawed assumptions:-
1. that predator extermination was the best way to protect biodiversity
2. that there was a need to eradicate every stoat, rat and possum to protect biodiversity.
3. that complete eradication of predators was possible.
Laurie Collins said predators existed everywhere and were part of Nature’s food web. Whales preyed on krill,
falcon preyed on tui and bellbird, morepork preyed on native lizards and rats preyed on mice while stoats preyed on
rats.
However attempted eradication by use of ecosystem poisons like 1080 upset the balance between species. Research
had shown eliminating most but not all rats, enabled surviving rodents to erupt in numbers so within three to four years
of a poison drop, numbers were three times original population.
“And along the way to the futile eradication dream, the poison has killed birds and he invertebrate creatures
such as insects that are food to a number of avian species.”
Laurie Collins said it defied belief that public servants were stubbornly aiming to achieve the impossibility of
extermination and that politicians like National’s Nick Smith and Maggie Barry and more recently the new Minister of
Conservation Eugene Sage were in pursuit of "the unachievable".
Laurie Collins who in his working career had first hand experience of 1080 from its first use in New Zealand in
1958 and in later years, said the realisation of the poison’s indiscriminate killing powers and slow cruel death to
birds and animals compelled him to strongly oppose its use.
“But then 1080 is the tool for an ideologically driven impossible dream in Predator Free 2050. It is
ecologically stupid and senseless,” he said.
He said the fact that kiore rat were introduced over 700 years ago and ship rats at least 200 years ago, showed
the lack of responsible thinking by adherents of Predator Free 2050.
“If rats as predators were going to wipe out birds it’s logical they would have done so within 50 years. But as
predator-prey relationships established, birds were abundant for centuries until a mere 30 years ago when the poison
industry began,” he said.
