    I was hoping Mr Rist that the ABC reporter Fiona Breen who got the wondrous ‘jolly’ to Macquarie Island would have shown extensive footage of the thousands of rotting and decaying rabbit carcases killed by the successful aerial drops of the anti-coagulant poision bait [Brodifacoum].

    Or did all those rabbits conveniently die down their burrows or get eaten by skuas and giant petrels?

    Having watched the highly sanitized ABC news reports on the Macquarie Island pest eradication project all I can say is some people will say and do anything to make a quid…five years to remove 6 rabbits.
    Suckers on you taxpayers!

    The highly sanitized ABC 7.30 report 16th May 2011 was again a cop out… only rabbit footage was of two mixo infected rabbits from the single release of mixo at least twelve years ago!
    The only way then was for them to put Spanish rabbit fleas down WARM burrows hoping it may transmit mixo to other rabbits and cross infect…it was an absolute failure.
    Still no footage of the rabbit plague or for that matter any rabbits in any numbers.

    Again they show burrows of seabirds on the severe slopes that a rabbit couldn’t even abseil to…

    No mention again of Macquarie Island being the most seismically active Island in the World…same old, same old with the fenced off plots carefully cultivated…they have been doing this on Maria Island for years to justify Wallaby and Kangaroo control.

    For Keith Springer to shrug off the mismanagement question from Tracy Bowden was the biggest cop out.
    Of course it is mismanagement, decades and decades of it, incidentally the PWS/DPIPWE only became interested in CAT ERADICATION when huge amounts of NHT MONEY became available.

    “A successful $1.2 million eradication program – funded under the Natural Heritage Trust by the Commonwealth and Tasmanian governments and which began in 1997 – has wiped out the feral cat population. Next week marks three years since a feral cat has been sighted. Now the island, 1500 km south east of Tasmania, has been officially declared cat free.”

    #44Thank you Russell for your response, is it any wonder that we claim that our government ministers are mostly ignorant or even stupid at times, they only know what the grubby lobbyists and hired spooks tell them.
    Money for mates, or even just to piss such big money up against the wall.
    The environment minister for Tasmania is now the new bloke Brian Wightman MP, prior to this it was a responsibility department of which it had Bryan Green meddling with it, then prior again was our Minister for Poisons Programs, the un-plucky David Llewellyn.

    (“Whew.”) Thankfully he didn’t make it back into his former favourite government control position during the last State election, our wildlife species are now a far more tractable even healthier group of creatures since the day of departure of that unusual pro-poisons fellow, David Llewellyn!!

    Re #41
    “Alternatively this island could be cleared with a combination of multiple entrapment’s, hunting dogs and a squad of trained shooters.”

    I believe one tender to do just that was put forward with a written GUARANTEE that all invasive pests would be exterminated within 12 months of commencing without harming a single non-target animal. It also came in at a fraction of the cost of the poison bombardment.

    Money for ‘mates’ I guess?

    David I can answer # 42 with one excerpt from the Senate Hansard 21st February 2011. Page 114-115-116.
    http://www.aph.gov.au/hansard/senate/commttee/S13568.pdf
    Senator ABETZ—If I may quickly go to Macquarie Island, did baiting cease in June 2010? If so, why?
    If I can try to lead the witness, to assist with time, was it because of the unprecedented number of bird deaths?
    Dr Terrill—Yes, what you have outlined is correct. There were an unexpected number of bird deaths. Those bird deaths have been investigated and the conclusion is that the baiting program should continue albeit in a
    modified form.
    Senator ABETZ—So the $1.3 million worth of bait, which is what I have been told, on Macquarie Island will continue to be used?
    Dr Terrill—I will have to check that. I am not sure of the number.
    Senator ABETZ—Take the dollar value on notice, please.
    End Hansard.
    Also a letter from Tony Burke’s office to Ian Rist on the 12 October 2010 confirms the unexpected number of bird deaths being the reason…no mention of bad weather as Senator Abetz had confirmed on page 115 and 116 of the previously mentioned Senate Hansard.
    Hansard page 115-116
    Senator ABETZ—Did you write a letter to a Mr Ian Rist on 12 October 2010 in which you said:
    While some undesired deaths of birds were anticipated as an unavoidable consequence of the Macquarie Island pest eradication program, the level of deaths was higher than expected … Baiting ceased in June 2010 and will not recommence until a review of bird deaths is complete.
    Mr Murphy—That sounds like a letter I wrote to Mr Rist.
    Senator ABETZ—Nowhere in that have you mentioned the weather as the rationale for stopping the
    program. Why not?
    End Hansard.

    Interesting point IF as the label on ALL the Pestoff bait currently on Macquarie Island suggests it is old and out of date…who is going to stump up the 1.3 million dollars for a new lot of fresh bait?

  7. David Obendorf

    March 20, 2011 at 3:13 am

    Minister Wightman states: “We saw just how challenging it can be last year when the project team had to pull out of baiting after the worst winter weather in many months [?years]. Although recent winter weather observations indicated that there should be around 24-28 days for flying, last winter only two-and-a-half days were suitable.”

    Do the BOM records for Macca last winter confirm that only “two-and-half-days were suitable” for flying helicopters?

    Is this a factual reason for the aborted Brodifacoum bait drop, or is it an excuse offered up after Commonweath Environmemt Minister, Peter Garrett ordered a halt?

    Over to you Mr Rist and Mr Boeder.

    Having had correspondence from both State and Federal ministers regarding this insane bombardment of deadly to most all creatures poison, I can only conclude that the government are just not interested in all the collateral killings.

    The general ministerial opinion is that whatever dies,’may,’in the fullness of time, begin to re-inhabit and begin to reproduce their offspring.

    Alternatively this island could be cleared with a combination of multiple entrapment’s, hunting dogs and a squad of trained shooters.

    Such inexpensive methods do not suit our ministers, not enough headlines in it for them to that denotes their all out chemical warfare plans.

    The power to save the avian species is not enough to satisfy the ego’s of our ministers, better to kill the whole damn lot and then pray for some sort of species regeneration.

    Broadifacoum is deadly to all species through consumption and absorption, the fact that it kills everything it encounters is the major reason for its ministerial acceptance.

    Never think that government ministers of either Lib/Lab persuasion care a hoot to the mass slaughter of native creatures, just look at what the forestry entities in Tasmania get away with?

    The fat ministerial salary cheques will continue to roll in regardless of the number of dead vulnerable and or threatened Native species.

    This high falutin’ paycheck after all, is the ministers prime objective in all aspects of their responsibilities.

    re # 39– has minister wightman & his fellow ministers in the lab-green cabinet given up on the $5 million looted from the treasury each year to fund the futile chase for reynard the elusive tasmanian fox, & is now poisoning sea birds etc on macquarie island instead . what is happening on near-by campbell islands & the other islands – expect further looting opportunities for later.

    expect will shortly hear that the tasmanian fox & the tasmanian tiger have been nominated for inclusion on the endangered species list.

    hopeless wastrels – look for the calls of hypocrite when volunteers are called for redundancies among employees providing essential services to tasmanians

    apologise to the tasmanian people & resign i say.

  10. Ian Rist

    Absolutely amazed at the answer given by Minister Wightman to the Dorothy Dixer posed by Labor’s Brenton Best in the Parliament this week 15/03/2011.
    Hansard:
    Mr BEST (Question) – Can the Minister for Environment, Parks and Heritage please advise the House on the status of the Macquarie Island pest eradication project?
    Mr WIGHTMAN – I thank the member for his question. The Tasmanian Government is committed to eradicating feral pests from Macquarie Island. The project to eradicate rabbits, rats and mice is the largest of its type ever attempted in the world. Carrying out eradication in such an environment is extremely challenging. We saw just how challenging it can be last year when the project team had to pull out of baiting after the worst winter weather in many months. Although recent winter weather observations indicated that there should be around 24-28 days for flying, last winter only two-and-a-half days were suitable. It was a disheartening experience for all of us, particularly the project team. As is typical of our professional team, they bounced back with great enthusiasm and began planning for the next visit to the island. I am pleased to report that preparations for the 2011 voyage are well underway.
    The eradication team consisting of about 28 Parks and Wildlife staff, contractors and four helicopters expect to depart to Macquarie Island on a scheduled Antarctic Division trip in mid-April. This will position them on the island five weeks earlier than was possible in 2010 and increase the window of opportunity for suitable baiting weather. As members may be aware, last year there was some non-targeted impacts on a number of bird species. An expert review of the program was commissioned to look at this issue. The recommendations of this review were approved by the State and Federal Environment ministers and approval under the Environment Protection and Biodiversity Conservation Act was provided in early February. To meet some of the conditions under this approval the size of the baiting team has been slightly increased and a focus of the overall team will be to reduce impacts on non-target species. These impacts are regrettable but it is not feasible in this type of operation to avoid them entirely. Short-term impacts are expected to be far outweighed by the benefits.
    The eradication program is essential to protect and restore the unique ecosystems on the island. Many plant and animal species on the island will not persist if we are not successful. Once aerial baiting is complete, highly-trained hunting dogs will be used to locate any surviving rabbits. The field work to complete rabbit eradication is expected to take up to five years. We know that this is a very difficult task for the project team. We are pleased that they are heading down and we wish them all the very best.
    Government members – Hear, hear.

    Well obviously they ignore their Federal Labor colleagues that do tell the truth…
    I have a letter from Tony Burke’s office signed by one Paul Murphy that states the baiting was abandoned last year because “the level of bird deaths was higher than expected. Baiting ceased in JUNE 2010 and will not recommence until a review of the bird deaths is completed.”
    JUNE 2010 ???..I REMEMBER A PRESS RELEASE ON 21 JULY 2010 that QUOTES the then Minister O’Byrne as claiming bad weather was entirely to blame for the cessation of baiting.
    Now I happen to know the exact truth why baiting was stopped… Federal Minter Garrett ordered it stopped, there was an election coming in August and it was not a good look…poisoned birds falling out of the sky everywhere.
    No mention at all of bad weather!
    This was again confirmed in the Hansard of Federal Senate committees on the 21st February 2011.
    So Mister Wightman and previous Minister O’Byrne…what’s your story?
    P.S. As usual the Libs sat sat there and didn’t say anything.

    Russell another factor is there is a big quid in all this…remember when Paula started the whole idea as a funding drive on behalf of Labor that it was all going to cost 12 million dollars, suddenly overnight when Federal Liberal said “we will only pay half” Paula suddenly decided it was all going to cost 24 million dollars.
    Malcolm Turnbull gave them 10 million just before the 2007 election and they have had a top up on that since… two questions …where is the Tasmanian contribution of 12 million and what happened to the original Turnbull 10 million?
    I hear they are looking for more funding to go back next year………………
    Only in Tasmania.

    Russell # 32. Some seventy species of birds inhabit Macquarie Island:
    http://en.wikipedia.org/wiki/Birds_of_Macquarie_Island
    Many of them never leave the Island, once again the reason for baiting in the winter when birds are absent was just more crap fed to what now is known an “unquestioning audience”.
    Simple question…if eight percent of the Brodifacoum baiting caused this much carnage imagine what 300 tonnes of bait would of done?
    Once again another badly thought out disaster…from the masters of disasters.

    August 26, 2010 at 10:27 pm

    “Oh no, the non-target species won’t take the baits.”

    Does anyone know when the migratory and local bird breeding season down there is?

    Wouldn’t it be best to bait when the birds have all gone for a while?

    Too simple isn’t it?

    August 26, 2010 at 1:07 pm

    This poisoning exercise performed in the manner of a military bombardment of poisons. was ever to include wildlife attritions.
    Currently the score-card reads rabbits and other feral vermin poisoned to death: an unknown number.
    Wild species either threatened or non threatened: a considerable body count well in excess of 300 avian species killed.

    This speak is referred to as collateral damage.

    The collateral damage of citizen victims in both Iraq and now the Afghanistan battle-fronts would now well exceed the total of feral species killed to date on Macquarie Island.

    Well done boys!(in a military perspective of course.)

    Well I must say I told you so….
    http://www.abc.net.au/news/stories/2010/08/26/2994378.htm

    With only eight per cent of the bait deployed we have an admission of 300 native birds killed, my informant tells me it was much worse than that.
    My informant also tells me Garrett’s advisors panicked with an election coming up,hence the early pull out…well Pete…….De ja vue.
    Where are The Greens in all this?

  20. Ian Rist

    May 27, 2010 at 8:56 pm

    Could all this erosion and landslide damage be anything to do with the fact Macquarie Island is one of the most, if not the most seismic active islands on the planet?
    The reason Macquarie Island received WHT listing was because of the geological significance and not because of the flora or fauna.
    Two of the unique species that were on Macquarie Island the Macquarie Island rail and the Macquarie Island parakeet are now extinct because of cats.

    Don’t you just the way the magic word Brodifacoum has been avoided through this Macquarie Island debate…
    the latest effort heard on PM via Mark Colvin ABC radio, just an “ordinary rat-bait” will be used to bait the feral animals.
    I suggest Mark Colvin someone has been telling you porkies…Brodifacoum is the most secondary poisoning prone toxin known to man.
    And the good old poison capitol of the world – Tasmania, is going to drop 300 tonnes of the stuff on Macquarie Island…what about all the ducks, waders and scavenging seabirds?
    This will be a monumental stuff up and will be the final nail in the coffin for Minister Peter Garrett, he can’t say he wasn’t warned on this one.
    Ultimately Mr Garrett you are responsible.

    Yeah well the way I read it is like driving a tack with a sledge hammer not a tack hammer.
    Why do us humans think we have the right to cause this type of suffering to animals?
    I disagree with poisoning in any shape or form.
    I mean after viewing a lot of video footage on Macquarie Island I can’t say I have seen a lot of rabbits, however, not having been there I cannot say how bad the situation is.
    What I do know is that photographs have been used to create another crisis situation and make things appear worse than they are i.e the albatross chick photo that was circulated with the mice eating the guano in the nest…the photo was captioned “death by a thousand cuts” to infer the mice were eating the chick alive. Well some research showed that photo wasn’t even taken on Macquarie Island – it was taken on the remote South African sub – antarctic Marion Island.
    Winter photos used to show depleted over grazed growth? C’mon boys and girls please try and earn your funding honestly.

    I was surfing the web the other night, and I found this quote from a Wilderness Society site:

    Recent TWS activities on Antarctic and Sub-Antarctic Issues – September 16, 2003
    In 1997, TWS’ National Campaign Director, Alec Marr, visited Antarctica and Heard and McDonald Islands as a guest of the Australian Antarctic Division. Later that year, after a long campaign, TWS played a pivotal role in gaining World Heritage Listing for Australia’s Sub-Antarctic Islands (Heard, McDonald and Macquarie Islands). In 1997, Alec successfully lobbied the Federal Government to commit $4 million to a feral cat eradication programme on Macquarie Island.

    Interesting to trace it back

    Re #12
    Yes but, wouldn’t it be wiser to use a bait specific to the problem, rather than “kill the fuckin’ lot” approach?

    If there are endemic species on the Island which will take the baits, that means more extinctions. Each extinction affects other plants and animal life around it, which in turn, eventually affects us.

    The lessons should already have been learned.

  33. Ian Rist

    May 21, 2010 at 6:44 pm

    There won’t be a lot of native species left after 300 tonnes of Brodifacoum, suggest you read up on it Don and have a look at some of the previous links on this thread especially the Scientific American thread in # 7 and #1.

  34. Ian Rist

    May 21, 2010 at 2:04 pm

    Interesting to note there were a few comments made on the ABC Stateline program last evening by the head of the Tasmanian Branch of the Australian Veterinary Association on the Macquarie Island baiting program.
    Why was Brodifacoum temporarily put on the poisons register when we already have the best rabbit poison known – Pindone…and no threat of secondary poisoning?
    The spokesperson stated it will be impossible to recover poisoned carcasses and there will be secondary poisoning, what risk assessment was done? Any?
    Smells to me like someone made a big quid out of this, maybe because they just can’t sell Brodifacoum in NZ would be a good start.
    This is what the New Zealanders think of Brodifacoum:
    http://www.youtube.com/watch?v=8xvcQxbo3gE&feature=related
    Interesting also to note Macquarie Island was nominated for World Heritage status not because of its Flora and Fauna but for its Geological features.
    After all its is a huge pile of guano sitting on top of a volcanic upheaval and has the most seismic activity of any Island on earth.
    Could this explain some of the “rabbit” induced land slides.
    Just another case of jobs for the boys.

    In the beautifully sanitized version of Macquarie Island baiting it was also stated that “the birds leave the Island in the winter”.
    I cite a list of the bird species found on Macquarie – goodness all those wild ducks are going think Christmas has come early with all those chook pellets.

    I notice the ABC Stateline Program last evening 14/5/2010 presented a very sanitized version of the debacle that is about to take place on Macquarie Island…nice and soft, bit like a bed time story really – don’t upset the children.
    I noticed also the word Brodifacoum wasn’t mentioned once by the people interviewed…no – they wouldn’t because of the reception they have received from the New Zealanders where it is totally banned for outdoor application.
    They are better to sell it to the Tasmanians that survive on government funding and taxpayers’ money.
    It is also very sad that Airlie Ward was so easily misled by a smooth talker.
    Meanwhile the animals and birds will die in agony in their thousands on Macquarie Island whilst the powers that be are sipping their lattes.
    To conclude I don’t have a problem with how many shooters and dogs go down there, however, the indiscriminate baiting will be a disaster.

    Here we have 290 tonnes of a toxin they now cannot sell in N.Z. So sell it to the dumb Tasmanians to be purchased with even dumber Federal money.

    And the impact from this action on other life..is?
    What other life will be impacTed and what are the flow-on effects likely to be? Do we know?
    Amazing scenario really, just to deliberately plant amounts of a really toxic long lasting poison on a sub-Antarctic island.

    http://en.wikipedia.org/wiki/Brodifacoum
    “Brodifacoum has a similar mode of action to warfarin. However due to very high potency and long duration of action (elimination half-life of 20 – 130 days), it is characterised as a “second generation” or “superwarfarin” anticoagulant.[3]

    Brodifacoum inhibits the enzyme Vitamin K epoxide reductase. This enzyme is needed for the reconstitution of the vitamin K in its cycle from vitamin K-epoxide, and so brodifacoum steadily decreases the level of active vitamin K in the blood. Vitamin K is required for the synthesis of important substances including prothrombin, which is involved in blood clotting. This disruption becomes increasingly severe until the blood effectively loses any ability to clot.

    In addition, brodifacoum (as with other anticoagulants in toxic doses) increases permeability of blood capillaries; the blood plasma and blood itself begins to leak from the smallest blood vessels. A poisoned animal will suffer progressively worsening internal bleeding, leading to shock, loss of consciousness, and eventually death.

    Brodifacoum is highly lethal to mammals and birds, and extremely lethal to fish. It is a highly cumulative poison, due to its high lipophilicity and extremely slow elimination.

    Following are acute LD50 values for various animals (mammals):[4]

    rats (oral) 0.27—0.30 mg/kg b.w.
    mice (oral) 0.40 mg/kg b.w.
    rabbits (oral) 0.30 mg/kg b.w.
    guinea-pigs (oral) 0.28 mg/kg b.w.
    cats (oral) 0.25 mg/kg b.w.
    dogs (oral) 0.25 mg/kg b.w.
    LD50 values for various birds varies from about 1 mg/kg b.w. — 20 mg/kg b.w.[3]

    LC50 (concentration prone of killing 50% of animals exposed to it) for fish:
    trout (96 hours exposure) 0.04 ppm[5]

    Given these extremely high toxicities in various mammals, brodifacoum is classified as “extremely toxic” (LD50 < 1.0 mg/kg b.w.) and "very toxic" (T+; LD50 < 25 mg/kg b.w.), respectively. Because of its persistency, cumulative potential and high toxicities for various wildlife species, it is also considered an environmental pollutant (N; noxious to the environment). The readiness of brodifacoum to penetrate intact skin should be noted, and brodifacoum and commercial preparations containing it should be handled with respective care and precaution because of its skin resorptivity.

    Shouldn’t the Bald Eagles painted on the fuselage be arse upside down?
    Couple of interesting sites below, same poison- brodifacoum, same delivery method- helicopters.
