"Wake up in paradise" is New Zealand's proud boast. It has a rightful swagger: its turquoise glacial lakes are ringed by untouched mountain ranges, while historic Māori sites speak of a people at one with the natural world.
​
But there are stains on the environment. In this corner of the South Pacific, waterways are increasingly polluted and, from the suburbs to the alpine peaks, an untold army of feral pests is running amok, putting about 80% of New Zealand's bird species at the risk of extinction.

A pest-culling operation on 12,500 ha north of Dunedin is aimed at decimating the possum population by poisoning and trapping.
​
OSPRI has sent pamphlets to residents in the area informing them of the next stages of its work over the next two years.

Whio, kereru, kiwi and New Zealand native bats will benefit from an aerial 1080 operation needed to eradicate bovine TB in the Ruapehu District.
​
The operation, over about 35,000 ha, will take place at a time around late July when fine weather is predicted, Ospri operations extension officer Phillip Dawson said.

Birds and bats could be threatened with local extinction if the Department of Conservation (DOC) cannot make more aerial 1080 drops this mega-mast season.

Forest and Bird warns a plague of rats sweeping unchecked across parts of the country will be followed by an invasion of stoats by spring.

Official maps released today have revealed the vast swathe of New Zealand wilderness under threat from a plague-fuelling "mega mast" - but officials say response plans can't be scaled up.
​
Forest & Bird is warning a nationwide rat plague is only about to get worse, and has pleaded with the Government and councils to increase their 1080 rat control programmes, before a stoat plague comes next.

Possum numbers in the West Coast's Perth River Valley area have potentially reduced from roughly 10,000 to just 30 after a new technique was used in a 1080 operation.
​
Zero Invasive Predators (ZIP) is in charge of the operation in the Perth River Valley area in South Westland. The operation is halfway through and has involved the deployment of 4 kilograms of 1080 per hectare so far.

Twenty-one years of intensive pest control in the Landsborough Valley is paying off. David Williams reports.
​
Colin O'donnell ambles towards the edge of silver beech forest near the Landsborough River, drawn by the high-pitched, repetitive call of a mohua. It's a call the Department of conservation ecologist has been following for more than 30 years.

An aerial drop of 1080 is set for a large area of the Kahurangi National Park to control a booming rat population.
​
This year's beech mast, or heavy seed production, is expected to lead to a heavy breeding season for rats taking advantage of the abundant food source.

A newly long-term study reveals kiwi chicks located in a North Island Forest are more likely to survive following the aerial 1080 operation, where the poison is dropped, to control pests.
