New Zealand's forests were once rich in bird life, but introduced predators have taken a terrible toll - including extinctions of some species. Pūkaha Mount Bruce is one of a number of sanctuaries aiming to eliminate predators and protect native wildlife. It was once part of Seventy Mile Bush, a stretch of dense forest that was settled (and largely cleared) by Scandinavians in the 1870s.
