We have to be graceful that Indonesia is situated on equator and has avast and dense tropical forest. Hence, Indonesia has numerous natural resources with its valuable biodiversity, not only for Indonesia nation, but also for the international society in general. The Indonesian tropical forest is in the third rank (based on on area) after Brazil and Zaire.Indonesia archipelago spreads over 5000km along the equator. Biogeographically, this country is affected by Indomalayan plain at the west side and Australasian at the east, on that account specifically Indonesia biogeography can be divited into seven main regions : Sumatera, Jawa - Bali, Borneo (including Natuna and Anambas), the Lesser Sundas (including Wetar & Tanibar), Celebes, Moluccas and New Guinea (including Aru and Kai islands). The Lesser Sundas, Celebes, and Moluccas are considered transitional region between Indomalayan and Australasian plains.
Amongst the 17000 islands in the archipelago, many of the have been separated from the main plains for thousands of years. Thus, these islands exhibit unique characteristics, and the have high entemism. This is one factor why Indonesia is rich species. Although Indonesia occupies only 1,3% of the global area, this country is endowed with abundant natural wealth. The abundance is indicated by the existence of a 10% of the total flowering plants in the world, 12% of the total mammal species, 16% of the total bird species, and 25% of the fish species in the world.
