Zealandia a Nature Reserve with a 500-Year Plan

“In the past 30 years, a wilderness has grown up in the heart of New Zealand’s capital – so successfully its neighbours now complain about the raucous racket of rare birds. But this is just the first step in a much longer plan for wilderness in the city,” Rina Diane Caballar writes in a story about Wellington’s ecosanctuary, Zealandia, for the BBC.

“Zealandia’s rich biodiversity can be attributed to the 8.6km predator-exclusion fence encircling 225ha of land. A group of conservation managers, engineers and scientists designed and tested a fence suitable to Zealandia’s needs – one high enough to prevent invasive mammalian predators such as ferrets and possums from jumping or climbing over, with a wire mesh wall to exclude pests down to the size of a mouse and an underground skirt to prevent rats and other animals from burrowing underneath,” Caballar writes.

“‘By creating an area that excludes all introduced mammalian predators, we’ve created a safe haven,’ Zealandia’s chief executive Paul Atkins says.

“Looking to the future, Zealandia has a 500-year vision of restoring the forest and freshwater ecosystems of the valley where it resides as closely as possible to their prehuman state. This five-century period is the sanctuary’s estimate of how long it would take for the forest’s original canopy to regrow.”
