New Guinea Highlands - Ecology

Ecology

The New Guinea Highlands are home to a great variety of Australasian plant and animal communities, distinct from the surrounding lowlands to the north and south of the central ranges and varying up and along the mountain ranges. The habitats of the mountains have been separated into two ecoregions, depending on their elevation, the tropical montane forests and alpine grasslands, but within these broad bands there is a variety of wildlife along the island as some of the mountains stand quite a distance from others with some species of plant or animal existing on only one or two mountains. Particular centres of plant diversity are: the Star Mountains area of western Papua New Guinea near the Indonesian border including Telefomin and Strickland Gorge; the Hunstein Range; Mount Giluwe, a major birdwatching area for Birds of Paradise; the volcanic limestone Kubor Range; the Bismarck Range/Mount Wilhelm/Schrader Range/Mount Gahavisuka, of which Mount Wilhelm is particularly rich in endemic species; and finally the Crater Mountain and Mount Michael in the Eastern Highlands.
