Country
Papua New Guinea
Papua New Guinea: 16 ecoregions. Each with its climate now and toward 2050, and its conservation tier.
Landscape and climate
Papua New Guinea's sixteen ecoregions are almost entirely tropical moist broadleaf forest, from the Southern and Northern New Guinea lowland rain forests and freshwater swamp forests up through the Central Range Papuan montane rain forests to the Papuan Central Range sub-alpine grasslands, plus island units like the New Britain-New Ireland, Solomon Islands, and Louisiade Archipelago rain forests. New Guinea mangroves line the coasts, and the Trans Fly savanna and grasslands in the far south is the one genuinely seasonal, fire-prone landscape. The gradient that matters for plants is elevation, not season: hot, constantly wet lowlands give way to cool, cloudy montane forest and finally open sub-alpine ground. Every ecoregion here holds a Nature Could Reach Half Protected rating, reflecting how much intact forest remains.
