Ecoregions of New Guinea
New Guinea, lying within the tropics and with extensive mountain areas, comprises a wide range of ecoregions. These include rainforests, grasslands and mangrove.
Terrestrial ecoregions
New Guinea is in the Australasian realm, which also includes the islands of Wallacea to the west, the Bismarck Archipelago, Solomon Islands, and Vanuatu to the east, and Australia and New Zealand.[1]
Sea levels were lower during the Ice Ages, which exposed the shallow continental shelf and connected New Guinea to Australia into a single land mass. Several nearby islands, including the Aru Islands, most of the Raja Ampat Islands, and Yapen, were also connected to the mainland, which allowed the flora and fauna of New Guinea and the continental shelf islands to mix.[2]
