This is the begining of a page on the whole 1080 air-dropped poison issue in New Zealand. It's very much under construction.
Be warned there are some unpleasant images of poisoned deer in this video: Poisoning Stewart Island.
But there is some great footage of kiwis - particularly right at the end.
The video below is a much longer and more distressing video about the toll 1080 takes on wild and domestic animals.
See here for discovery that one of the Graf Brothers, makers of the videos above, was convicted bank robber in 1986 to ten years imprisonment
For an opposing view - supported by New Zealand's Department of Conservation - see here - this is a Joint Federated Farmers and Forest and Bird: Giving Nature a Voice 1080 website.
This is the Wikipedia site on 1080 usage in
It suggests that the massive use of 1080
'remains a contentious issue, with the majority of the debate occurring between conservationists and livestock farmers on one side and hunters and animal rights activists on the other.'
The report Evaluating the use of 1080: Predators, poisons and silent forests by the Parliamentary Commissioner for the Environment, (June 2011)
The Forest and Bird conservation's support for 1080 is explained in this fact sheet.
With regard to birds it says the follwing,
Because 1080 operations dramatically reduce possum numbers and often kill stoats, rats and deer, they allow native bird populations to recover and then thrive. Research has shown that the nesting success of kereru, tomtits and robins improves considerably following aerial 1080 operations. For example, after 1080 treatment in Pureora Forest, twice as many robins nested successfully as those outside the affected area. Within a year the robin population had increased by 37%, compared to only a 16% increase in the untreated area. Thus, despite some individual birds being killed, the increase in breeding success allows bird populations to bounce back and increase rapidly. The recovery of forest vegetation after possums are killed means nectar, berries and other food sources increase, benefiting bird life.
