Ecology

The island is part of two ecoregions. The New Britain–New Ireland lowland rain forests extend from sea level to 1,000 metres (3,300 ft) elevation. The New Britain–New Ireland montane rain forests cover the mountains of New Britain above 1,000 metres (3,300 ft) elevation.

Forests on New Britain have been rapidly destroyed in recent years, largely to clear land for oil palm plantations.Lowland rainforest has been hardest hit, with nearly a quarter of the forest below 100 metres (330 ft) disappearing between 1989 and 2000. If those rates of deforestation continue, it is estimated that all forest below 200 metres (660 ft) will be cleared by 2060. Despite this, most forest birds on New Britain are still widespread and secure in conservation status, though some forest-dependent species such as the New Britain kingfisher are considered to be at risk of extinction if current trends continue.
