NEXT supported environmental initiative Zero Invasive Predators has undertaken a ground breaking trial in Perth River Valley, South Westland.

The ZIP team carried out a challenging operation to completely remove possums, stoats and rats from 12,000 hectare of rugged back country – part of the strategy towards a Predator Free New Zealand.

Four months after the operation was completed results are in – the team has detected no stoats, and only a small number of possums and rats in the trial area.

How was the trial carried out, and what’s happening now to prevent predators from re-establishing in this mainland area?
