Story: Land birds – overview
The 250-hectare Karori Sanctuary is surrounded by an 8.6-kilometre predator-proof fence. In this photograph the bird sanctuary is on the left side of the fence. Designed to exclude all introduced mammalian predators, the fence has an overhanging cap to keep out climbing possums, cats and stoats, and very fine mesh that even tiny mice cannot wriggle through. Beneath the ground, the mesh extends outwards for more than a metre to prevent rats or dogs from burrowing in. The fence is inspected every week to check for damage. Within the sanctuary, bird numbers are increasing dramatically – including several species that were brought close to extinction by predators elsewhere.
