519 3 Agency App. F “Snails take about 3 years before young big enough to detect..further monitoring [to assess effects of 1080] needed” (translocation of snails by DoC will have left juveniles, also large risk of trampling damage)
520 1 Agency App. F “Hochsetter’s..frogs were monitored..during an aerial operation..no change was detected in the Hochsetter’s..population but [statistically] there was only a very small probability of detecting an impact because the number of frogs [was] too small..no conclusions could be drawn”
520 2 Agency App. F “Archey’s frogs were monitored..during an aerial operation..declines in numbers occurred in both treatment and control areas [during the four months after control]..attributed to seasonal and/or disturbance factors”
521 1 Agency App. F “Groups of bats were captured when returning to their roost and held in captivity for 48 hours (to assess mortality after a 1080 cereal operation]. No [deaths] or signs of poisoning occurred..further information..is needed..to fully assess the potential impact of 1080”
537 1 Agency App. F “One non-target kill has been reported in association with the 10% gel, where one weka..was seen paralysed..and died 15 minutes later..proximity to area..indicated 1080 was the likely cause, with baits having slipped off treated leaf surface”

750 2 Agency App. N “The attractiveness and palatability of..non-toxic baits and lures to wild-caught short tailed bats [4 females and 46 males] were assessed in an enclosure in 3 separate trials”
754 3 Agency App. N “The responses of [35] captive skinks to..non-toxic..cereal baits and to..cereal bait containing pindone [an anticoagulant used mainly for rabbit control] have been evaluated..consumption of the wetted baits increased significantly, with no difference between the 2 types of bait..the Agency was not able to locate any information on the palatability of carrot bait to lizards”
45 1 Applicants’ references “Kauri snails were not contaminated. These analyses were based on a small sample and should be treated accordingly” (Eason et al., 1991)
70 1 Applicants’ references “[skinks] ate..[cereal] bait..sublethal effects require further study” (Freeman et al., 1996)
92 1 Applicants’ references “50% of the weta offered the toxic [1080 ‘grain based’] baits died, while the other 50% suffered sublethal poisoning which altered their behavioural patterns” (Hutcheson, 1990)
109 3 Applicants’ references “Monitoring involved catching a sample of 269 bats as they arrived at a roost after foraging, then holding them in captivity for 48 hours..although..several replicate trials are required before a generalised conclusion can be drawn about the fate of short-tailed bats following aerial 1080 operations” (Lloyd & McQueen, 2002)
111 1 Applicants’ references “Wild-sourced eels were acclimatised for 21 days in a wet-laboratory before being exposed to 1080 [32 eels used in Trial 1 and 48 used in Trial 2]” (Lyver et al., 2004)
164 2 Applicants’ references “No radio-tagged kereru and too few radio-tagged kaka bred to show [effects of possum and rat numbers after poisoning]..while no radio-tagged adult male kaka died during the study, 6 females did..radiotagged kereru suffered high mortality..predation was the main cause of mortality” (Powlesland et al., 2003)
