Predator Eradication: New Zealand's Plan to Save Native Birds.

New Zealand aims to eradicate rats, stoats, weasels, ferrets, and possums by 2050 to protect its unique ecology and save its native birds. The government has marked these predators for eradication, and Predator Free 2050 Ltd has been set up to channel government and private money into local projects to test eradication strategies. The most ambitious of them is Predator Free Wellington, which aims to kill off a range of pests, notably rats, which thrive in urban environments. The project's 36-strong team has turned amateur rat-catchers into proper exterminators.
