More 1080 drops in 'Battle for our Birds'

The controversial pest poison 1080 will be used to deal with an expected explosion in rat and stoat numbers this year which threatens to "annihilate" the country's native endangered birds.

Hailed as the Department of Conservation's largest ever species protection programme, and dubbed the 'Battle for our Birds', the $21 million project aims to protect 25 million native birds a year over the next five years.

It was unveiled tonight by Conservation Minister Nick Smith at his annual speech to the Rotary Club of Nelson.

"Our native birds are in decline and the kiwi will not exist in the wild for our grandchildren unless we do more to protect them," he said.

He said the problem was "particularly urgent" this year, because the country was facing a one in 10-15 year large beech mast, which is expected to drop around a million tonnes of seed this autumn.

"This flood of food will trigger a plague of an additional 30 million rats and tens of thousands of stoats. When the seeds germinate in spring, these starved predators will annihilate populations of our endangered birds," he said.

The programme will increase pest control in 35 forests to protect 12 native species, and mainly involves using 1080.

Dr Smith said he was aware some people would object to the use of the controversial poison, but said it would not mean record use.

"Pre-feeding, improving bait quality to avoid crumbs attractive to birds, helicopter rather than fixed-wing aircraft distribution, GPS, and the development of repellents for non-target species have enabled major improvements in 1080 control methods," he said.

"Reason must trump prejudice about poisons when the very species that define our country, like kiwi, are at stake."

An additional 500,000 hectares will be treated this year, and will also see the expansion of DoC's pest control work by 50,000 hectares each year over the next five years.

The plan is aimed at helping to protect the great spotted, brown and tokoeka kiwi, kaka, kea, whio (blue duck), mohua (yellowhead), kakaraki (orange-fronted parakeet), rock wren, long and short tailed bats, and giant snails. But is expected to also help save other native birds, reptiles, insects and trees and plants.

The programme will cost about $21 million over the next five years, coming from DoC's $335 million annual budget, Dr Smith said.

 

DoC director-general Lou Sanson said field staff would be closely watching the seed fall and rat-tracking results from key sites over the next few months.

"We need to be ready to act quickly to knock back rat or stoat numbers before they overwhelm birds which are particularly vulnerable during the spring nesting season."

It was concerned that its existing trap and ground-based networks would be overwhelmed if predator numbers rose rapidly.

"Our best, and fastest, option for protection over large tracts of rugged bush is using biodegradable 1080 baits by air."

Forest & Bird, New Zealand's largest conservation charity, backed an increase in the use of 1080 as a "fitting response" and the level of its use over the next five years should become the new baseline if the ongoing battle against introduced predators is to be won. "Without this increase in predator control, there will be a real possibility that we will lose a bird species this mast year. Ground control operations carried out by Forest & Bird branches around the country are already reporting increased numbers of rats. That means the stoats will follow," Forest

& Bird advocacy manager Kevin Hackwell said.
