Flora & Fauna

British naturalist A. R. Wallace (1823-1931) postulated an imaginary line (named after him Walace's Line) as the dividing line between Asiatic and Australian fauna. It passes between Bali and Lombok islands between Kalimantan and Sulawesi, then continues south of the Philippines and north of Hawaii.

This theory probably explains the presence of species of fauna familiar to both Asia and Australia found in Indonesia. However, there are species indigenous to Indonesia, like the "orang utan" apes of Sumatra and Kalimantan, the giant "komodo" lizards which are the only ones of their kind in the world today roaming free on the island of Komodo; the one homed rhinoceros of Java, the wild "banteng" oxen, tigers and many other species which are now protected in wildlife reserves.
