  • My comment about kaka, relates to the Tararuas. they are prolific in karori and pukaha, because of intensive control / eradication. ie stoats etc. also, the Tararuas is a good example of impacts of pest. species like kokako, kiwi, robins , whio etc became locally extinct long before 1080 was ever used kaka and other populations are decimated. all through predation or habitat destruction
  • Cheers t.hunter that's the kind of info I'm after.
  • I'm involved in a kokako protection program and we have a 5 yearly 1080 drop, the other years are done by a very labour intensive ground baiting program, over rugged country. If the labour had to be paid for it would make the program cost prohibitive. Something like 2000hrs a year and we only bait over the breading season. The results speak for themselves, from 6 pairs there are now in excess of 140 pairs and many are taken each year to repopulate other areas. other species like Kaka and robins have also increased significantly. 1080 works, there are things still to be learnt and no one denies this, the application is being continuous refined. There is no question it work and stories about dead birds everywhere simply are not true. The number of dead deer and pigs are low as well contrary to anti 1080 propaganda (and aren't they pests anyway?). Even if we killed every deer we could if we wished reintroduce them tomorrow, you can't do that with a Kiwi. There is a nice study published recently about the effect of 1080 on Sika deer in the Kaimanawas using motion sensitive cameras. Their conclusion (and they did ground study to verify) about 10% of the deer population was killed and at the concentration of deer they encountered (I've forgotten the exact number) this was definitely not a problem. As others have said no one likes the idea of spreading poison but as the Parliamentary Commissioner for the Environment (now ex) Dr Jane Wright said "we are lucky to have it". It's a poison designed to kill manuals and we have no native ground manuals. Around the Kokako we protect with 1080, bats have noticeably increased with them now being often seen at dusk. Dave Hansford's book is great as he deals with science no wild conjecture. As he says in his book the anti 1080 lobby has yet to put a single piece of peer reviewed science which supports their claims. Theres' is all rhetoric, half truths and outright lies. A lot of what seems to underlie their "case" is some sort of conspiracy theory, and Gaiters hints at this as well. Doc are lying (why) and spreading 1080 is the end in itself, again why?. Doing nothing certainly will be the end our native birds. Read the science! Hansford is a good place to start, easy to read and he gives plenty of other sources. The science is so one sided that if you still don't believe after reading it then I suggest you don't want to be convinced.
  • From what I've read the conspiracy theory goes along the lines that goverment based decision-making individuals have invested in the 1080 manufacturing. I meet a broad spectrum of humanity in my work and the odd person raises the 1080 issue, including statements such as no other country uses it. I remind them that other countries have native mammals they are trying to protect. Nice to read the bats are making a comeback in the kokako country up there.
  • @Honora, that's the thing that sets me off all the time, statements like "no other country does use 1080." Clearly objectively false, and if you point it out to them it doesn't register. Six other countries use it, and at least Australia does aerial drops too. It's very hard to get a fact based discussion with the anti-1080 people.
  • and at least Australia does aerial drops too Its worse than that. 1080 occurs naturally in south Australia. If our possoms had come from there 1080 would not have worked. People forget that 1080 is in fact a copy of a naturally occurring substance. Same as pyrethrin and pymethrin being essentially the same chemical but one comes from oil the other from daisys and marigolds. Different scale though
  • I read that there are around 60 species of plants in Australia with significant amounts of 1080 naturally present. I'm so glad that Camilla sinensis only has a little.
  • ... and because Australian native animals have co-evolved with naturally occurring 1080, they have a resistance to the poison (at Aus dosage rates) and are very unlikely to be killed by it (although a short-term effect if enough bait eaten). That would explain why NZ dosing rates are so much higher than Aus - you are trying to kill possums that have that resistance. Aus target species are foxes, pigs, dogs, cats etc that are very susceptible to 1080.
