Introducing Papua New Guinea
The island of New Guinea, of which Papua New Guinea is the eastern part, is only one-ninth as big as Australia, yet it has just as many mammal species, and more kinds of birds and frogs. PNG is Australia’s biological mirror-world. Both places share a common history going back tens of millions of years, but Australia is flat and has dried out, while PNG is wet and has become mountainous. As a result, Australian kangaroos bound across the plains, while in PNG they climb in the rainforest canopy.
PNG is one of earth’s megadiverse regions, and it owes much of its diversity to its topography. The mountainous terrain has spawned diversity in two ways: isolated mountain ranges are often home to unique fauna and flora found nowhere else, while within any one mountain range you will find different species as you go higher. In the lowlands are jungles whose trees are not that different from those of Southeast Asia. Yet the animals are often startlingly different – cassowaries instead of tapirs, and marsupial cuscus instead of monkeys.
