New Zealand has been geographically separated from other land masses for over 80 million years and, with the absence of land mammals, our native wildlife has evolved in isolation.
When Europeans arrived they introduced animals which later became pests and predators. These took a serious toll on the native plants, birds, reptiles and invertebrates, who were ill-equipped to deal with such a threat.
Controlling pests is essential for the survival of New Zealand's plant and animal species.
New Zealand Conservation Trust's Predator Control Project
The Trust has an extensive trapping programme consisting of 400 DOC200 double traps placed in the Craigieburn Forest Park, Castle Hill, Broken River and Bealey Spur.
As at 2014 there have been over 1000 predators caught in these traps, the majority of those being stoats.
These traps are instrumental in protecting native wildlife from predators such as stoats, ferrets, weasels, rats and hedgehogs.
A number of dedicated volunteers from the Trust as well as volunteers from the Canterbury Environment Trust give up their free time to check, clear and reset the traps.
