Java is an island with a large amount of biodiversity. The [[natural environment]] of Java
Java is an island with a large amount of biodiversity. 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 and subtropical moist broadleaf forests|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.{{cn|date=December 2023}}

Since ancient times, people have opened the rainforest, altered the ecosystem, shaped the landscapes and created [[Paddy field|rice paddy]] and terraces to support the growing population. Javan rice terraces have existed for more than a millennium and had supported ancient agricultural kingdoms. The growing human population has put severe pressure on Java's wildlife, as rainforests were diminished and confined to highland slopes or isolated peninsulas. Some of Java's endemic species are now critically endangered, with some already extinct; Java used to have [[Javan tiger]]s and [[Javan elephant]]s, but both have been rendered extinct. Today, several national parks exist in Java that protect the remnants of its fragile wildlife, such as [[Ujung Kulon National Park|Ujung Kulon]], [[Mount Halimun Salak National Park|Mount Halimun-Salak]], [[Gunung Gede Pangrango National Park|Gede Pangrango]], [[Baluran National Park|Baluran]], [[Meru Betiri National Park|Meru Betiri]], [[Bromo Tengger Semeru National Park|Bromo Tengger Semeru]] and [[Alas Purwo National Park|Alas Purwo]].
