In the west of Java lies the Halimun Reserve, today integrated into the Mount Halimun Salak National Park. A tiger was killed there in 1984, and pugmarks found in 1989 were the size of a tiger's. However, an expedition of six biologists conducted in 1990 did not yield any definite, direct evidence for the presence of a tiger. A subsequent survey was planned in Meru Betiri National Park in autumn 1992 with the support of WWF Indonesia, deploying camera traps for the first time. From March 1993 to March 1994, cameras were deployed at 19 locations, but did not yield a picture of a tiger. During this period, no tracks indicating the presence of tigers were discovered. After the final report of this survey had been published, the Javan tiger was declared extinct.
