Karori Wildlife Sanctuary is a protected natural area where the bio-diversity of a square mile of forest is being restored.
A predator-proof fence, specifically designed to exclude 14 species of non-native mammals, ranging from possums to mice, encircles the 8.6km perimeter. The Sanctuary is at present in a degraded state. Flora now missing from the site or rare – including large podocarp species such as rimu and totara – will be re-established. Many species of threatened native wildlife will be re-introduced. The Sanctuary will be developed as a major education, research and recreational site for the benefit of all New Zealanders.
Eighteen captive-bred Brown Teal were released in the Karori Wildlife Sanctuary between November 2000 and April 2001.
