Agency App. C |
“factors such as a decrease in ‘trappability’ of possums in winter may have an influence in assessing the operational outcomes” |
481 |
3 |
Agency App. F |
“the RTCI [residual trap catch index] may not be accurate” |
487 |
5 |
Agency App. F |
“ongoing predation [during poisoning] managed by intensive trapping around nest trees” |
488 |
3 |
Agency App. F |
“in non-treatment area, RCTI dropped to 11.5% in February 2002, with no significant differences between treatment and control by Feb 2002…decline in control block due to poisoning and trapping for fur” |
507 |

Agency App. F |
“Ship rats, stoats, possums [predators of Kereru]..ongoing predation noted after 1080 operation which achieved RTCI of 4.4% and rodent tracking index of 5% immediately after the operation..four years’ sustained ground control..including intensive trapping around nest trees..improved nesting for at least one season” |
531 |

Agency App. F |
“To demonstrate efficacy in terms of percent kill [in DoC possum operations], the timing of the pre-control and post-control RTCI monitoring had to have occurred within 1 year before, and within 3 months after, the operation” (seasonal effects on possums numbers and trappability are likely however) |

Agency App. O |
“The applicant estimates areas of land that would not be treated under a cyanide/trapping scenario..but there is too little justification in the application for the Agency to evaluate this analysis” |
772 |

Agency App. O |
“Significant numbers of weka have been caught where they gain access to traps..DoC [now requires] traps..where ground birds are known to be present, to be set 700 mm above the ground..weka continue to be caught..the effectiveness of the new guidelines is not known” |
773 |

Agency App. O |
“The catch rates reported..may..represent a significant percentage of the kiwi population..McLennan et al (1996) report that extensive surveys showed that about 10% of adult kiwi had damaged feet or toes, which they attributed to having been caught in leg-hold traps over the previous 2-3 decades..the actual catch rate will be [30-50%] higher taking account of birds injured fatally, and natural attrition of the ‘marked’ [damaged] population” |

Agency App. O |
“Blue penguin..paradise shelduck..brown teal..Australasian harrier..pukeko..southern black-backed gulls..kereru..kakapo..kaka..kea..kakariki..long tailed cuckoo..morepork..pipit..fantail..tomtit..robin..bellbird..tui..and kokako..have all been caught in traps..most..caught in leg-hold traps that have been set on the ground without surrounding barriers to reduce accidental capture of non-target species” |
774 |

Agency App. O |
“traps raised to protect native ground birds have a higher risk of trapping birds such as kereru, morepork, and kaka” |
774 |
3 |
Agency App. O |
“records of bird by-catch include some very small species..indicating that the traps must have been set very lightly” |
775 |

Agency App. O |
“complete eradication [of pests with cyanide/trapping] is possible, as on Kapiti Island” |
776 |

Agency App. O |
“[percentage kill..aerial 1080..intial control 87.9%, maintenance control 39%..traps only initial control 79.2%, maintenance control 78.6%]” |
776 |

Agency App. O |
“[costs per hectare of control]..aerial 1080 $24..traps & cyanide $18..traps only $19” |
777 |
3 |
Agency App. O |
“the percentage kill..indicates that trapping can be as effective as aerial application” |
778 |

Agency App. O |
(costs and time were reduced, and kill rates increased, when ground control (cyanide and traps) was supplemented with dogs) |

Agency App. T: Submissions |
“A trapper in our area has found no lesions on any possums he has trapped. Other species than possums can spread Tb, and our numbers of pigs with Tb are increasing” |
911 |

Agency App. T: Submissions |
“We have proven that by encouraging coordinated and targeted trapping that possums (and rats as a by-product)..can be controlled to low numbers (using humane and kill traps) and harvesting a valuable resource” |

Applicants’ references |
“Trapping and poisoning only provide short-term solutions to the possum problem and often involve methods that involve suffering. [Many of the] Intrusive experiments connected with these methods..do not attain the welfare standards required by members of the public” (Morris & Weaver, 2003) |

Submitter 9142 |
“It appears that ferrets are capable of transmitting infection to stock.. [2 experiments have demonstrated that where] ferret populations have been reduced by trapping, the incidence in Tb declines” (Ragg & Byrom review) |

Committee Decision |
“The Committee notes that 1080 is the only available vertebrate pest control agent able to control multiple pest species” |

Committee Decision |
“neither [trapping or shooting] are wholly reliable in terms of reducing suffering” |

Committee Decision |
“The Committee notes that [on-going suffering from a sub-lethal dose] applies to all vertebrate pest control methods” |
