    Corbett, Greg; Paterson, John (LakesWater Quality Society, 2017)

  • 1080 and the fight to save New Zealand's wildlife

    Hansford, Dave (LakesWater Quality Society, 2017)
    I grinned when I saw the title of the symposium was ‘Troublemakers’. I am here because I wrote ‘Protecting Paradise’ and in it I looked at the science around 1080. I explored some of the popular myths and fallacies around ...
