The '''Western Java rain forests''' ecoregion (World Wildlife Fund ID: IM0168) covers the lowland rain forests below 1,000 meters in elevation in the western half of the island of Java in Indonesia. There are a variety of forest types - evergreen, semi-evergreen, moist deciduous, and even some patches of freshwater swamp. The forests have degraded by conversion of the low areas to agriculture, and by logging. National parks protect some of the last remaining untouched rain forest. A number of endangered mammals are found in the ecoregion, including the Javan rhinoceros, the silvery gibbon, and the Javan surili.<ref name="wwf">{{cite web|title=Western Java rain forests|url=https://www.worldwildlife.org/ecoregions/im0168|publisher=World Wildlife Federation|language=en|access-date=March 21, 2020}}</ref><ref name="ecomap">{{cite web|title=Map of Ecoregions 2017|url=https://ecoregions2017.appspot.com/|publisher=Resolve, using WWF data|language=en|access-date=September 14, 2019}}</ref><ref name="dopa">{{cite web|title=Western Java rain forests|url=https://dopa-explorer.jrc.ec.europa.eu/ecoregion/40168|publisher=Digital Observatory for Protected Areas|language=en|access-date=August 1, 2020}}</ref><ref name="eoe">{{cite web|title=Western Java rain forests|url=https://editors.eol.org/eoearth/wiki/Western_Java_rain_forests|publisher=The Encyclopedia of Earth|language=en|access-date=August 28, 2020}}</ref>
== Location and description == The ecoregion surrounds the interior volcanic mountain ridge of western Java, stretching 500 km in length but nowhere more than 60 km wide. Above 1,000 meters in elevation the ecoregion transitions into the Western Java montane rain forests ecoregion.<ref name="eoe"/>
== Climate == The climate of the ecoregion is ''Tropical monsoon climate'' (Köppen climate classification (Am)). This climate is characterized by relatively even temperatures throughout the year (all months being greater than {{convert|18|C|F}} average temperature), and a pronounced dry season. The driest month has less than 60 mm of precipitation, but more than (100-(average/25) mm. This climate is mid-way between a tropical rainforest and a tropical savannah.<ref>{{cite web|first1=M. |last1=Kottek |first2=J. |last2=Grieser |first3=C. |last3=Beck |first4=B. |last4=Rudolf |first5=F. |last5=Rubel |date=2006 |title=World Map of Koppen-Geiger Climate Classification Updated|url=http://koeppen-geiger.vu-wien.ac.at/pdf/Paper_2006.pdf|publisher=Gebrüder Borntraeger 2006|language=en|access-date=September 14, 2019}}</ref><ref name="kop-data">{{cite web|title=Dataset - Koppen climate classifications|url=https://datacatalog.worldbank.org/dataset/world-maps-k%C3%B6ppen-geiger-climate-classification|publisher=World Bank|language=en|access-date=September 14, 2019}}</ref>
== Flora == Almost 40% of the ecoregion is either under cultivation for agriculture or in built-urban areas. The remainder is 40% closed evergreen broadleaf forest, 14% open forest, and 6% other cover.<ref name="dopa"/> The forest is, however, highly degraded by logging. The evergreen forest's common plants include ''Artocarpus elasticus'' (a tree in the mulberry family), yellow mahogany (''Dysoxylum parasiticum''), langsat (''Lansium domesticum''), and ''Planchonia valida'' (a tree in the ''Lecythidaceae'' family). The areas of moist deciduous forest generally have 1,500 to 4,000 mm/year of precipitation. These forests feature palmyra palm (genus ''Borassus'') and palm trees of genus ''Corypha''.<ref name="eoe"/>
== Fauna == The ecoregion supports 101 species of mammals, five of which are endemic. Mammals of conservation interest include the critically endangered Javan rhinoceros (''Rhinoceros sondaicus''), the endangered silvery gibbon (''Hylobates moloch''), the endangered Javan surili (''Presbytis comata''), the vulnerable fishing cat (''Prionailurus viverrinus''), the endangered banteng (''Bos javanicus''), and the endangered Sunda slow loris (''Nycticebus coucang'').<ref name="eoe"/>
== Protected areas == Only 2% of the ecoregion is officially protected.<ref name="dopa"/> These protected areas include: * Mount Ciremai National Park * Mount Halimun Salak National Park * Ujung Kulon National Park
