There is one at www.planet-mammiferes.org (see the entry for Javan Tiger). Here is another one from a German book  source Wilhelm Eigener Die Enzyklopaedie der Tiere (1971) |

I found some really interesting information on the Javan tiger on this pdf file web.whittier.edu/people/webpages/ personalwebpages/rmarks/PDF/Asian_Tigers.pdf -
apparently Javan sultans had water buffalo and Javan tigers fight against each other as entertainment for European visitors. I'm not sure the date, but it was probably around the 1800's or even before that. It also has some info on the population status from the 1800's to 2000 of the population status of the Malayan, Sumatran, Javan and Balinese tigers.

3. Panthera tigris (Linnaeus) subsp. from Java, as given by Stremme (1911), von Koenigswald (1933), and Brongersma (1935) from various Pleistocene localities. So tigers were present on Java for a long time not recent. PLEISTOCENE AND RECENT TIGERS Very interesting file digitallibrary.amnh.org/dspace/bitstream/2246/2316/1/N1346.pdf |

The last reaible report of a Javan tiger is from 1982 (which seems quite possible as there was at least 3 left 1979), prints and dropping was found in 1990 but a year long studie 1993-1994 didnt managed to find any reaible signs that confirmed the countine survival of tiger on Java.

Similar to the Sumatran and Bali subspecies of tiger, the Javan tiger (technical name Panthera tigris sondaica) was uniquely isolated in both geographic and political terms to a single water-locked island. Even before research escalated regarding the viability of the Sumatran tiger, significant and original research had been conducted regarding the status and viability of the Javan tiger. In particular, John Seidensticker and his Indonesian colleague Ir. Suyono conducted the first comprehensive field research on the island of Java in the mid-1970s. Unfortunately, the picture revealed by this early research was bleak; few tigers could be found on the island, and trends in the decline indicated the likely extinction of the subspecies within a decade-due completely to the corruption of their habitat by the infiltration of human beings. (Java, with an area of 132,000 kilometers and a population in excess of 130 million people, is the most densely populated island on Earth). Unfortunately, here the worst case scenario developed for tigers. Along with the Caspian and Bali tigers, the Javan tiger is now extinct - none exist in either the wild or in captivity. All that remains are photographs and pelts. The last observation of a Javan tiger that was formally documented occurred in 1972. (Two important related points must be observed here: First, there have been recent anecdotal reports of Javan tiger sightings associated with the wildfires that raged across Java in 1997 and 1998; these incidents, however, were later determined to have involved leopards. Second, the term "extinction" is formally recognized among scientists to mean the absence of any official sightings of an animal for no fewer than 50 years. Hence, while the Javan tiger is universally presumed to be extinct, it cannot yet be technically categorized as such.) In genetic terms, the Javan tiger could have supplied an opportunity for research as valuable as that of the Bali and Sumatran subspecies, had any of its progeny survived. The classifications used to categorize tigers by subspecies were implemented long before the details of genotyping were refined to the degree they have been today. Furthermore, the burgeoning field of genetic analysis had not achieved the techniques necessary to take full advantage of the animal's uniqueness before its demise. The relational proximity between the Sumatran, Javan and Bali tigers might have provided unique insights into the effectiveness of our subspecies identification techniques; techniques essential in the application of conservation strategies. During 1998 and 1999, The Tiger Foundation received reports from Indonesian park rangers of numerous tiger sightings in and around some national parks in Eastern Java. Some of the evidence included photographs of tree scratch marks, pug marks (paw prints) and scats (droppings). The scats were sent to a laboratory in the USA and a team was dispatched to investigate the reports. The Tiger Foundation provided support to the Indonesian Ministry of Forestry, which set several of our camera traps in the forest. Many photographs of animals were taken; no evidence of tigers was found. The scats turned out to be bear droppings. We have concluded that the reported cats are in fact leopards, which are still common in Java. The Javan Tiger is undoubtedly extinct. www.tigerfdn.com/Tigerworld/javanframe.html |

I'd like to see a genetic comparison between Sumatran and Javan tigers, I'd imagine they're not that different and for all intents and purposes see no reason why Sumatran tigers aren't reintroduced to National Parks in Java.

The number of prey (sambar deer, muntjac and Bateng) is to low on Java today, there is no chance that a stable population will bee able to live on this Island, at least not with the current situation, the animals would be poached and wouldent last very long, Java already has a good population of other carnivores, the dhole for ex has taken the tigers place on Java, the leopard is another canrivore, there is simply to little space on Java today to support three large carnivores. |

I agree with sebbe67 Java nowadays wouldn't be able to support a stable population of any other carnivores.

I was editing some pages on Wikispecies and came across the following: species.wikimedia.org/wiki/Panthera_sondaica>> species.wikimedia.org/wiki/Panthera_sondaica_balica>> species.wikimedia.org/wiki/Panthera_sondaica_sondaicaI found a pdf on this: arts.anu.edu.au/grovco/tiger%20SEAsia%20Mazak.pdfMazak J.H., C.P. Groves. 2006. A taxonomic revision of the tigers (Panthera tigris) of Southeast Asia. Mammalian biology 71, 5:268–287. Deutsche Gesellschaft für Säugetierkunde. AbstractThe taxonomic affinity of Southeast Asian tigers is re-investigated. Specimens of four traditionally recognized subspecies are examined using various craniological methods, including multivariate craniometric and phenetic analysis. Sumatran tigers differ absolutely (100%) from the geographically neighbouring mainland form P.t.corbetti; the Javanese tiger is also 100% distinguishable from the Sumatran. They are therefore regarded as two distinct species ( P.sumatrae, P.sondaica) under the Phylogenetic Species Concept (PSC). The Bali tiger is classified as a subspecies of the Javanese tiger, Panthera sondaica balica. |
