The taxonomic affinity of Southeast Asian tigers has been re-investigated by J.H. Mazák and C.P. Groves. Specimens of four traditionally recognized tiger (Panthera tigris) subspecies were examined using various craniological methods, including multivariate craniometric and phenetic analysis. They conclude that Sumatran tigers differ absolutely (100%) from the geographically neighbouring mainland form Panthera tigris corbetti; and that the Javanese tiger is also 100% distinguishable from the Sumatran. According to these scientists they are therefore regarded as two distinct species (Panthera sumatrae, Panthera sondaica) under the Phylogenetic Species Concept (PSC). The Bali tiger is than classified as a subspecies of the Javanese tiger, Panthera sondaica balica. (Mazák and Groves 2006) However for now, The Extinction Website still regards the Javan tiger as Panthera tigris sondaica. This may change when there is consensus among scientists about its true taxonomy.
|Characteristics||The Javan tiger was quite similar in appearance to the still existing Sumatran tiger, but had numerous darker and closer-set black stripes. Striping on the flanks and back was often double-looped. This dense pattern of stripes was characteristic for this subspecies. This subspecies was also notable for their cheek whiskers that were the longest of any of the subspecies. (Van den Hoek Ostende. 1999)|
|Range & Habitat||The
Javan tiger occurred on the Indonesian island of Java (Jackson
& Nowell 2008).

|History & Population||
oldest tiger fossils from Java date from 1.2 million years ago. This
prehistoric tiger, Panthera tigris trinilensis, was found at the
locality of Trinil, which also yielded the oldest human remains of the
island, the famous Java-man. These tiger fossils are now stored in the Dubois Collection of the National
Museum of Natural History in Leiden, the Netherlands. Although these
fossils have been found on Java, they probably do not belong to a direct
ancestor of the Javan tiger. During the Ice Ages the larger Indonesian
islands were regularly connected to the mainland, which allowed faunal
exchanges. The last time such immigration occurred was during the late
Pleistocene, some 50.000 years ago. Tigers, which probably migrated from
China, reached Java again. As the sea level rose, the tiger population
became isolated and finally developed into the Javan subspecies.
the early 19th century Javan tigers were so common all over
Java, that in some areas they were considered nothing more than pests. As
the human population rapid increased, large parts of the island were
cultivated, leading inevitably to a severe reduction of their natural
habitat. Wherever man moved in, the Javan tigers were ruthlessly hunted
down or poisoned. The Javan tiger experienced growing competition for prey
species with wild dogs and leopards. Natives carried much of the hunting
out, a surprising thing since they considered the tiger a reincarnation of
their dead relatives. By 1940, tigers had become restricted to remote
mountain ranges and forests. In the mid-1950s only 20-25 Javan tigers
remained on Java. During the 1960s the Javan tiger even disappeared from
the famous Ujung Kulon reserve on the western tip of Java, where nowadays
the last Javan rhinoceroses live. The last stronghold of the Javan tiger
was a rugged area in southeastern Java, known as Meru-Betiri, which had
become a game reserve in 1972. It was considered this tiger's last chance
for survival. However, even it was declared a reserve, the area was under
attack by agricultural development. A track count revealed that in 1979 at
most three Javan tigers where still living there. The Javan tiger has not
been seen or tracked since. The exact time of extinction remains unknown,
but this subspecies must have become extinct in the early 1980s.
(Van den Hoek Ostende. 1999)
reports still surface of few tigers to be found in East Java. Meri-Betiri
National Park, the least accessible area of the island, is located here
and considered the most likely area for any remaining Javan tigers.
Despite the continuing claims of sightings it is far more likely that the
Javan tiger has become extinct. The 'tigers' are quite likely to be
leopards seen from a distance.
|Extinction Causes||The Javan tigers were driven to extinction though a rapid increase in human population leading inevitably to a severe reduction in habitat for the tigers, which e.g. resulted in growing competition for prey species with wild dogs and leopards. Forests were felled and than converted for agricultural use. The Javan tigers were also merciless hunted and poisoned.|
|Conservation Attempts||The establishment of nature reserves in the 1940s and later could not save the Javan tiger, because tigers need a large area with a rich food supply. The reserves were too small and too far apart, and therefore could not maintain tiger populations. Besides, the amount of prey species was too low. Captive breeding was maybe an option, because there have been captive Javan tigers in Europe. They could be found in Rotterdam Zoo (the Netherlands), Berlin Zoo (Germany), and maybe in Budapest Zoo (Hungary). However, it is likely that the Javan tigers in Budapest were in fact Sumatran tigers. The Javan tiger was common in Indonesian zoo collections before World War II, but during the war these zoos were disbanded. Following the war, when zoo collections were re-established, Javan tigers were very rare in the wild and it was much easier to obtain Sumatran tigers, so the zoos hadn’t any Javan tigers anymore. But sadly enough no conservation attempts have been made in captivity.|
|Museum Specimens||The National Museum of Natural History “Naturalis” in Leiden, the Netherlands, has two mounted skins of Javan tigers, one skeleton and ten skulls. The first skin (young female) was obtained in 1820 or 1821 in western Java by three of the first Dutch zoologists to explore the Netherlands East Indies (nowadays Indonesia), namely Heinrich Kuhl, Johan Christiaan van Hasselt and Gerrit van Raalten. Heinrich Kuhl and Jahan Christiaan van Hasslt collected the skeleton too. The first director of this museum, Coenraad Jacob Temminck, used these specimens when he described Felis tigris sondaica in 1844. The second skin is from an adult male Javan tiger that was imported into the Netherlands from Java on 10 June 1920 and died in Rotterdam Zoo in February 1931. (Van den Hoek Ostende. 1999) Also Wiesbaden Museum in Germany has a mounted skin of the Javan Tiger in its collection. It was collected on Java in 1825.|
|Relatives||The Bali tiger was the first subspecies of the tiger to become extinct. Unfortunately, since then, further two subspecies, namely the Caspian Tiger and the Javan Tiger, have become extinct. The six remaining tiger subspecies are the Bengal tiger Panthera tigris tigris (Linnaeus, 1758), Siberian (Amur) tiger Panthera tigris altaica (Temminck, 1844), Sumatran tiger Panthera tigris sumatrae Pocock, 1829, Indo-Chinese tiger Panthera tigris corbetti Mazak, 1968, South China tiger Panthera tigris amoyensis (Hilzheimer, 1905), and the Malayan tiger Panthera tigris jacksoni (Lou et al., 2004). The six remaining subspecies are all critically endangered en may follow the extinct ones soon, if nothing more will be done to protect them! (Lou, et al, 2004)|
