Zealandia (wildlife sanctuary)

Zealandia, formerly known as the Karori Wildlife Sanctuary, is a protected natural area in Wellington, New Zealand, where the biodiversity of 225 ha (just under a square mile) of forest is being restored. The sanctuary was previously part of the water catchment area for Wellington, between Wrights Hill (bordering Karori) and the Brooklyn wind turbine on Polhill.Most of New Zealand's ecosystems have been severely modified by the introduction of land mammals that were not present during the evolution of its ecosystems, and have had a devastating impact on both native flora and fauna. The sanctuary, surrounded by a pest-exclusion fence, is a good example of an ecological island, which allows the natural ecosystems to thrive by minimising those introduced pressures.The sanctuary has become a significant tourist attraction in Wellington and is responsible for the greatly increased number of sightings of species such as tui and kākā in city's suburbs.Sometimes described as the world’s first mainland island sanctuary in an urban environment, the sanctuary has inspired a raft of similar projects throughout New Zealand, with predator-proof fences now protecting the biodiversity of many other areas of forest. Examples include the 7.7 hectare lowland podocarp forest remnant of Riccarton bush/ Putaringamotu, the 98 hectare Bushy Park and, the 3500 hectare Maungatautari Restoration Project enclosing an entire mountain.
