he largest 1080 poisoning operation in New Zealand conservation history is about to get under way in northern Buller and Tasman.
The Department of Conservation is planning to carry out aerial 1080 pest control over about 270,000ha of the Kahurangi National Park this spring as part of its Battle for Our Birds predator control programme to protect native species from a plague of rats and stoats.
It was met with protests outside DOC’s Takaka office this week.
The cost of the aerial drop was about $4.3 million, DOC spokeswoman Fiona Oliphant said.
It is the largest area in DOC’s Battle for Our Birds predator control programme, and has been broken up into six operational blocks of between about 20,000 and 60,000ha.
The Kahurangi operation is one of 25 confirmed Battle for Our Birds operations using aerially-applied 1080 poison over about 680,000ha of conservation land to knock down rising predator numbers fuelled by the unusually heavy seeding in South Island beech forests.
Six operations have been completed. The largest operational block completed to date is 30,000ha at Waitutu forest, in Southland.
DOC Motueka conservation services manager Mark Townsend said it was estimated that without pest control, rat tracking levels would reach 100% in November in parts of Kahurangi National Park.
