A remote corner of southwest New Zealand faced a costly, but vital, battle against invasive predators to protect its unique biodiversity.


  1. Chalky Island is a predator-free sanctuary for threatened species.
  2. A stoat was successfully trapped and killed to protect vulnerable species like the kākāpō.
  3. Stoats, introduced to control rabbits, have wreaked havoc on birdlife.
  4. New Zealand has a Predator Free 2050 plan.
