The Javan tiger was a Panthera tigris sondaica population native to the Indonesian island of Java. It was one of the three tiger populations that lived in the Sunda Islands during the last glacial period 110,000–12,000 years ago. It used to inhabit most of Java, but its natural habitat decreased continuously due to conversion for agricultural land use and infrastructure. By 1940, it had retreated to remote montane and forested areas. Since no evidence of a Javan tiger was found during several studies in the 1980s and 1990s, it was assessed as being extinct in 2008.
