Range restriction & dwindling populations

In many of the places where kiwi were once common, they are now just a distant memory. Where kiwi are not protected from predators, the range over which kiwi are found is still in decline. Predation means too few chicks survive to replace adult birds, while ferrets and dogs can quickly wipe out adult populations.

When small remnant populations of kiwi are lost we also lose their whakapapa – their unique DNA. This may make kiwi less adaptable, and inbreeding is a risk as populations become increasingly fragmented and isolated.

However, we have the tools and ability to turn this loss around. Many projects have been able to undertake effective pest control which has seen populations rise. Kiwi are able to live in a wide range of habitats, such as production forest and farmland, as long as we protect them from dogs and other dangers. With strong community support, people and kiwi are able to live side by side.

There is urgency to act. Where kiwi are still hanging on, we can protect and rejuvenate these populations.
