Karori Wildlife Sanctuary

Karori Wildlife Sanctuary

Karori Wildlife Sanctuary is a protected natural area in Wellington, New Zealand, where the bio-diversity of 225 ha (just under a square mile) of forest is being restored. The sanctuary covers an area that was previously used as the water catchment area for Wellington, between Wrights Hill (bordering Karori) and Kowhai Park. The sanctuary is a good example of an ecological island.

The most crucial aspect of the sanctuary is a pest-exclusion fence - specifically designed to exclude fourteen species of non-native land mammals ranging from possums to mice - that encircles the 8.6 km perimeter of the Sanctuary. Construction of this fence was completed in 1999 and all fourteen species of mammalian pests within the perimeter were then eradicated. This predator proof fence is of great conservation significance - being a world first. In terms of its meeting conservation goals Karori wildlife sanctuary has met with considerable success thanks to the effective design of the encircling fence. As of 2006 the fence has been successful in excluding all but the smallest species - the house mouse.

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: 98 hectare Bushy Park in Wanganui, the 7.7 hectare lowland podocarp forest remnant of Riccarton bush/ Putaringamotu in Christchurch city and perhaps most notably a 3,500 hectare tract covering an entire mountain thanks to the Maungatautari Restoration Project in the Waikato.

The flora and fauna in the sanctuary is at present recovering from its pre-managed degraded state - the original primary forest that covered the valley was burnt off in the 1850s and 1860s and was farmed up until 1906 - the native forest has been regenerating ever since but in most areas is still only in the early stages of succession with small hardy trees such as Mahoe dominating. Members of the original flora that are now missing from the site, or rare - include large podocarp species such as rimu, matai, miro, kahikatea, and totara - are being re-established. Northern rātā has also virtually disappeared from the valley and a number of seedlings have been planted. A wide variety of native trees, of benefit to native fauna, is already present including a mature colony of the New Zealand tree fuchsia, "Fuchsia excorticata".

The sanctuary has become a significant tourist attraction for the city of Wellington and is responsible for the existence of a greatly increased number of sightings of species such as tui and bellbirds in city's western suburbs.
