The Department of Conservation and the 1080 Fraud

 About a year ago we learned that DoC was routinely and indiscriminately dropping food laced with tonnes of a universal poison, 1080 into our forest ecosystems. Ostensibly, this aerial poisoning of our forests is being done to control possums.

DoC asserts that only possums and other so called “pests” are significantly poisoned. As scientists and life-long environmentalists, we were struck that this contention appears to violate the most fundamental ecological principles as well as common sense. Is it plausible that one could drop food mixed with a poison that kills all animals into a semi-tropical ecosystem and only negatively affect possums and other “pests”?

This question is particularly relevant now in light of the upcoming aerial 1080 drop into the Coromandel watershed. In science, extraordinary claims require extraordinary evidence. We resolved to determine whether the extraordinary claims of DoC have the weight of extraordinary evidence behind them. The answer is unequivocal: they do not.

After months of investigation, we found that 1080 research, almost entirely sponsored and controlled, by DoC sustained six conclusions, which given the large cost and risks of DoC’s aerial 1080 program we find truly astonishing.

First, there is not a single scientifically credible study showing that aerial 1080 when used on the mainland is of net benefit to any species of New Zealand’s native fauna, let alone has the general salvational effects claimed by DoC.

Second, there is overwhelming evidence from DoC’s own research that aerial 1080 is killing large numbers of native animals, including birds, insects and other invertebrates, and our only native mammal, the bat. Moreover most native species are entirely unstudied.

Third, there is not a single ecosystem level study showing lack of harm, let alone showing the overwhelming beneficial effects that DoC claims. In fact 1080 drops often increase stoat and rat populations.

Fourth, while it is probable that possums, if left unchecked, would over time do some damage to our forests, the degree of that damage is not known and whether that damage is being controlled with aerial 1080 without irreversible damage to the forest ecosystem is entirely unproven.

Fifth, DoC’s 1080 research is generally of poor scientific quality, is obviously biased as one would expect given the fact that the researchers owe their jobs to the goodwill of the DoC bureaucracy, and it does not actually show what DoC claims.

Sixth, in any case, it is clear from AHB research that there is a clear alternative: ground based baiting with species specific bait stations. In short there is absolutely nothing in the scientific record that would justify the following statement from DoC’s May 14 press release: “Without 1080, the price New Zealanders would have to pay in the loss of their unique species and habitats is too awful to contemplate.”

To the contrary, DoC’s own science tells a depressingly grim story. DoC habitually, publicly and aggressively misrepresents what its research shows. For example, DoC claims in its ERMA submission “that robin nesting success more than compensates for any robin losses from 1080”. This is absolutely false.

The cited study showed increased nesting success in 1 of 3 years, but even that single success failed to translate into increased robin population success -- the bottom line. The study also showed that 54% of banded robins died in the 1080 poisoned area compared to none in the un-poisoned area.

DoC has claimed that Kereru populations are increased by aerial 1080 treatment, and yet the only study published on the subject was methodological nonsense, which proved nothing, but incidentally “showed” that Grey Warblers and Silvereye populations decreased in the 1080 treated area, an observation never mentioned by DoC’s otherwise highly efficient public opinion control machine.

DoC claims that the tomtit is not affected by aerial 1080 bait, and cites a study done by Westbrooke in 2005 to prove that. However, the published paper actually shows that substantial numbers of tomtits could be being killed even by low concentration cereal baits, and more important it shows that about 40% of tomtits died when exposed to low concentration carrot baits!!! Yet this is never mentioned by DoC. Carrot bait is still in widespread use by DoC.

DoC claims that bats are unaffected by aerial 1080. However, a competent 2002 study by Lloyd and McQueen showed that bats were clearly poisoned. The study gave a “best estimate” that 14% of bats would be killed in 14 foraging flights in a 1080-poisoned area...»Next
