New Zealand’s Mainland Islands Fencing Out Non-Native Predators

Islands often serve an important role in protecting and preserving species because of their isolation and lack of predators. But some species aren’t suited to the offshore ecosystem, and some countries don’t have the islands to devote to conservation efforts. New Zealand has decided to import the benefits of offshore island habitats inland by creating “mainland islands,” typically surrounded by large predator-resistant fences. Despite early success, the effort is meeting some skepticism and resistance.
