“[the Otago Regional Council] does not screen bait used for rabbit control.” |
485 |
4 |
Agency App. F |
“[the Otago Regional Council’s] sowing rates for rabbit control (10 to more than 40 kg/ha) are much greater than that used for possum control, resulting in a significantly larger number of baits being available for ingestion by target and non-target species” |
485 |

Agency App. F |
“increased abundance of tui and silvereyes [on Rangitoto Island 8-9 years after eradication of possums and wallabies]..the abundance of insectivorous and seed-eating birds did not increase [possibly because of] the ongoing presence of ship rats, stoats and cats” |
509 |
3 |
Agency App. F |
“Additional seed produced [after browsing animals were removed from Rangitoto Island] may have led to increased seed consumption by rodents..[which] also consume large quantities of invertebrates, also reducing the resources available to birds” |

“NZ has a multiplicity of important ecologically challenging, animal control problems that must be seen to be believed..However, where enough soil has remained..a new and stable equilibrium of the animal-vegetation-soil complex has developed..a long-term objective toward the noxious animal problem is to strive for habitat stability” (Howard, 1965) |

“Comparison of the Whitecliffs data with that of other lowland podocarp/broadleaf forests over one year, shows that 1080 has a severe impact on many other invertebrates. At Whitecliffs, insect larvae, comprising coleoptera, hymenoptera, diptera and lepidoptera dropped dramatically from July through to October, then stabilised for the rest of the year at the crash level. Insect larvae in other forests followed the normal pattern of continual rise from July until the onset of the following winter” (Meads, 1994) |

“At least 9 invertebrate orders are prone to 1080 poisoning. Invertebrates have been observed eating baits..their habitats are contaminated by residues leaching from baits, and from animal by-products and carcasses..1080 should not be used where susceptible invertebrate species or rare insectivores are found” (Notman, 1989) |

“No major changes to the [aquatic] invertebrate communities was observed, except for a decrease in the total number of taxa collected in some streams 5 days after the [1080] drop.. [and a] slight decline in the EPT taxa collected 5 days after the drop. Such decreases were not evident at the control site” (Suren & Lambert, 2002) |

“I am a retired Conservator of Wildlife ..have been opposed to the bulk sowing of 1080 since the late 50s and early 60s..when I witnessed its obvious ability to kill other than the target species in large numbers. Its use on rabbits decimated the huge quail and chukor population of Central Otago as well as every other species of ground bird, hawks, moreporks and falcons that were attracted to the baits, the dead rabbits and the secondary kill of rats and insects etc.” |

“scientific research supporting [DoC’s] claims [mostly] reaches only the lowest levels of control quality. Statistics are often poorly done, absent or selectively reported. The studies are short term and narrow in scope. There is not one randomized, blind treatment. Results are frequently misrepresented and distorted often with obvious bias. There are numerous errors of inference, omission and commission. Roughly half of the studies are only published internally..mostof the others are published in a single journal, the NZ J Ecology. There is only one study that appreaed in a peer reviewed international journal…The entire lot, excepting one or two, was produced by researchers who are financially dependent on DoC’s good will” (Whiting-O’Keefe review) |

“The Leopold Board made several recommendations for reform. It called for the establishment of a permanent advisory board of predator and rodent control, and representation by a ‘wide spectrum of opinions’..It suggested that the [US] Fish and Wildlife Service reassess its own goals ‘in the light of changing public attitudes toward wildlife’..It called for sharp federal controls on the use of 1080..when secretary Udal accepted the Leopold Report in March, 1964, and announced it would become..policy..Sheepmen yelled bloody murder, and descended on their congressmen in bus-loads” |

“The [US] 1080 poisoning programme went on for a few years, until the predators and raptors were almost gone. The bald and golden eagles that had been common in the valley were seen only rarely, and hilltops that had rung with the howls of coyotes now were still and silent..Then the rodents hit the valley like a horde of locusts. With hardly any meat-eaters left to control their sharply multiplying numbers, the rodents popped up everywhere” |
