 The Parahyangan highlands of West Java receive over annually, while the north coast of East Java receives annually.The natural environment of Java is tropical rainforest, with ecosystems ranging from coastal mangrove forest on the north coast, rocky coastal cliffs on the southern coast, and low-lying tropical forest to high altitude rainforest on the slopes of mountainous volcanic regions in the interior.The Javan environment and climate gradually alters from west to east; from wet and humid dense rainforest in western parts, to a dry savanna environment in the east, corresponding to the climate and rainfall in these regions.Originally Javan wildlife supported a rich biodiversity, where numbers of endemic species of flora and fauna flourished; such as the Javan rhinoceros, Javan banteng, Javan warty pig, (tiger), Javan hawk-eagle, Javan peafowl, Javan silvery gibbon, Javan lutung, Java mouse-deer, Javan rusa, and Javan leopard.
