Introduced predators like rats, possums and stoats are a major problem for New Zealand’s plants and animals. For millions of years, our native wildlife evolved without the threat of ground-based mammal predators. This means they are vulnerable to predation and unable to defend themselves.
Since people and predators arrived on our shores, dozens of species have gone extinct. Today, around 4,000 of our native wildlife and plants are at risk of meeting the same fate. So long as rats, possums and stoats remain in New Zealand, our native wildlife will continue to decline and those threatened with extinction could vanish forever.
