The small, flightless bird had been absent from this eroded volcano in the Waikato for approximately a century, driven out by the rats, stoats, and possums that had colonized New Zealand's forests with devastating efficiency. Its return was the first proof that an audacious experiment was working. Sanctuary Mountain Maungatautari is not merely a nature reserve. It is a 3,400-hectare ecological island on the mainland, sealed off from the outside world by 47 kilometres of specially engineered pest-exclusion fence, and it has become one of the most important conservation projects in the Southern Hemisphere.

Photo credit Public domain. The fence is not infallible. Storm damage in July 2007 required quick repairs. Kakapo proved that even flightless birds can outsmart a barrier if the right tree falls in the right place. Mice still live inside the enclosure. But Maungatautari has demonstrated something that matte...
