The Javan Tiger


CharacteristicsThe 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.Range & HabitatThe Javan tiger occurred on the Indonesian island of Java.History & PopulationThe 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.
The tiger fossils, reckoned among the oldest in the world, 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. In 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. Occasional 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.
Some agencies are carrying out experiments using infrared activated remote cameras in an effort to photograph any tigers. Authorities are even prepared to initiate the move of several thousand natives should tiger protection require this. But until concrete evidence can be produced, the Javan tiger must be considered yet another subspecies of the tiger to be extinct and lost forever.Extinction CausesThe 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 AttemptsThe 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 SpecimensThe 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.RelativesThe 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 five 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, and the South China tiger Panthera tigris amoyensis (Hilzheimer, 1905). These 5 subspecies are critically endangered en may follow them soon, if nothing more will be done to protect them!

Lesser One-horned rhinoceros


Ujung KulonMeru Betiri 760 sq km of the peninsula and sea on Java's very remote south-western tip is devoted to Ujung Kulon National Park. Several offshore islands are included in the reserve, Peucang, Panaitan and one of which is the remains of a pre-16th century volcano. In 1883 the island of Rakata Besar exploded dramatically. It lost about half of its land area in the process and sent tidal waves across the Indian Ocean causing the deaths of 36,000 people. The smoking cone which can be seen today signals Anak Krakatau, offspring of the famous Krakatau. It appeared in 1929 and has continued to grow steadily. Java island is one of the most geologically active places in the world.

Ujung Kulon has large tracts of undisturbed lowland rainforest, swamps and beaches. Because it is protected on three sides by sea, and on the fourth by the Honje mountains, it has provided a refuge for wildlife, some of which are now rare in the rest of heavily populated Java (population: over 100 million). In the mid-1950s only 20-25 tigers remained on Java. Half of these were in Ujung Kulon, but these are known to have vanished by the 1960s. The exact time of extinction for the Javan tiger remains unknown, but this was probably sometime in the 1980s. It was after this time, between 1980 and 1986 that the number of wild areas of Indonesia officially designated National Parks rose from five to sixteen. Ujung Kulon was one of the earliest preserved areas, first being protected in 1910, then declared a reserve in 1937. Come 1980 the designation was changed and became Indonesia 's first National park. Ujung Kulon has always been of extremely high conservation value and contains several species of endangered or threatened animals. Oriental small-clawed otters, hornbills, leopards, Asian wild dogs, Javan leaf monkeys, crocodiles, green peafowl, Javan gibbons, Javan warty pigs, green turtles, milky storks and Banteng wild cattle all make their homes here. In total, over 350 species of animals and 250 species of birds have so far been recorded here.

The most important resident of the park is the Javan or Lesser One-horned rhinoceros. This is the most endangered large mammal in the world and only two wild populations remain (there are no Javan rhinoceros in captivity). Ujung Kulon contains 50-60 animals while Cat Tien National Park in Vietnam has another 10-15 with different physical characteristics. The two subspecies used to be common over India, Bhutan, Bangladesh, China, Myanmar, Thailand, Laos, Cambodia, Vietnam, Malaysia, Sumatra and Java. In an attempt to save the small stable population in Ujung Kulon, efforts are being made to prevent the illegal access which is gained both from land and sea. Though the number of rhino is not increasing, the age structure shows change, so it is thought the amount of poaching is higher than originally considered. This cancels out the expected yearly population increases. Having said that, there have indeed been some rises in numbers. Back in 1967 Ujung Kulon rhino plunged to an all time low of 21-28 animals. The population originally came under threat due to loss of habitat, and medicine or sport hunting. Male rhino are most at risk from poaching as they have the dense formation of hair which makes up a large horn. Females usually have no horn, and when they do, it's insignificant. As with tiger bone, rhino horn is highly valued in traditional Asian medicine, and also in common with the tiger, there is no proof it has anymore effect than a placebo. Its primary use is as an aphrodisiac. It is possible the present population may be at or near carrying capacity; the park maximum is estimated to be in the region of 80-100 rhino. Translocation of excess animals to restock Vietnam is not able to be done. The two groups are very different and cross-breeding is not thought to be possible. Translocation of rhino is very difficult anyway with low survival rates. Even if placed in captivity these large mammals would have a very high mortality (about 30%); this is usual for captive rhino. Fecal DNA analysis and camera traps are being utilised to gain a better understanding of the current population. Habitat, food availability, and the possibility of translocation are also under examination. Like all Indonesian National Parks Ujung Kulon continues to increase in popularity. Though reaching Ujong Kulon is expensive and usually involves a long boat ride which, except for the dry season, can be a rough trip, it is now one of the most popular National Parks on Java. Even the thought of the recommended malaria shots don't seem to put visitors off. Fortunately, access to the area is strictly controlled and a permit must be gained for entry, while guides are required for those wanting to hike through the park.

A Brief Introduction to Gamelan Music


Normal 0 false false false MicrosoftInternetExplorer4

Gamelan is a Javanese/Indonesian word for ensemble. The word "gamel" means to hammer something in Javanese and , indeed, "hammering" or hitting is the way in which most of the different instruments in the ensemble are sounded with the exception of the two stringed instruments -- the bowed fiddle (rebab) and the plucked zither (siter) -- and the flute (suling), male chorus (gerong) and female soloists (pasindhen). Most of the instruments are made from cast bronze and are in the shape of hanging gongs (gong, kempul) and racked gongs (bonang and kenong) which look like gongs lying on their backs with the boss facing up towards the ceiling. There are metallophones (saron) (like xylophones but made from metal, in this case, bronze polished to a gleaming luster) and drums (kendhang) played with the hands. The drummer and the bowed instrument player are the leaders of the group, one determining melodic transitions and the other determining rhythmic transitions. No single person stands in front of the ensemble and conducts. The musicians must listen and rely on their understanding of what is "usual" in a piece of any particular form and "special" or pamijen in a particular piece in order to play it properly. The music is cyclic, often composed of several different cycles, each of which is repeated an undetermined number of times. Each cycle begins and ends with the stroke of the biggest gong (gong agung) which is, itself, named Nyai Saraswati. The length of individual cycles can be as short as 30 seconds or as long as 20 minutes. As most pieces are composed of several different cycles, each played several times, the duration of pieces can range from a few minutes to more than an hour, rivaling a Mahler or Beethoven Symphony in terms of complexity, movements, and duration.

The late 19th century composer Claude Debussy heard gamelan at the 1889 World's Fair in Paris. He was transfixed and spent many days in the Dutch East Indies Pavilion listening to the Indonesian musicians perform. He worked hard to understand the structure and tuning. He later set about composing music inspired by the Javanese music he heard. Some of the other composers who have been inspired by Indonesian gamelan traditions include: Maurice Ravel; Oliver Messiaen; Benjamin Britten; Colin McPhee; Harry Partch; John Cage; Lou Harrison; Peter Sculthorpe; Anne Boyd; Steve Everett; and many contemporary Indonesian composers such as I.M. Harjito; B. Subono; Tony Prabawa; Franki Raden; I Wayan Sadra; and Otok Bima Sidarta.

Western musicians who hear gamelan are struck both by the complexity of the relationships between the melody lines of the different instruments and, if they are aware of the "rules" of western harmony, by the almost "impressionistic" tone clusters that can be heard if the listener hears the music vertically, or tries to interpret it "harmonically". People without musical training often focus on the melifluousness of the sound and the soothing, meditative quality of some of the music. Others are excited by the multileveled interlockingness of the texture, comparing it to the experience of listening to several, incredibly good jazz solo players improvising together.

Indonesia is a big country, consisting of many cultures with many musical traditions. The biggest culture, with the most highly refined musical tradition, is that of the Javanese. The island of Bali also supports a distinct classical tradition. The music of other cultures has also been recorded, but I will not be dealing with that, as it has more the character of folk art.

Since many readers are apparently less familiar with the Javanese cultural setting (as opposed to India, China or Iran), I will discuss this background before proceeding to the list of recordings. The language we call Javanese is spoken in the central and eastern parts of the island of Java. The western part is Sundanese (from which there are also a few recordings, not to be discussed). Javanese is a very complicated language, consisting of three distinct vocabularies and grammars to be used with those in superior, equal, or inferior social positions with respect to the speaker. The national language of Indonesia is a modern construction, designed for simplicity and easy use by the wide array of different cultures within its boundaries.

Prior to the European period, Javanese was the dominant culture of the region, at times holding hegemony in parts of the Asian mainland. For instance, in the early-medieval history of what is now Cambodia, a restoration of the traditional monarchy was heralded by the arrival of a prince from Java to take the kingship. During the Mongol era, a large invasion fleet (much larger than that sent to Japan) was sent to Java, only to be soundly thrashed at sea, without a landing. This will give the reader some idea of the Javanese strength, but it should also be noted that this hegemony was generally not expressed through military means (at least insofar as we understand it), but rather as cultural and trading superiority. Of course, this situation was drastically modified by the arrival of the Arab traders.

Indonesia is counted as the most populous Muslim nation in the world, but this is somewhat misleading. Islam is not a "state religion" as it is in many Islamic countries, and there is quite a bit of variety, although the majority of inhabitants do profess Islamic beliefs. Among the larger cultures, North Sumatra is the "most" Muslim; in fact, it was home to a major Islamic University (known, for instance, in China) during the later medieval era. Java is also Islamic, in the sense that the people believe in many of the tenets of Islam and identify themselves as Muslims, but there are also other simultaneous belief systems. Prior to Islam, Java was alternately Hindu and Buddhist (and Bali remains Hindu), and these beliefs continue to be important for Muslim people. There is also an older layer of native religious practice which is still alive and well. Javanese religion is termed "syncretistic" (i.e., combining various influences), and it is generally only our tendency to give priority to the monotheistic religions which yields the Javanese the designation of "Islamic" per se. Of course, the influence of Islam should not be understated either.

The above discussion of syncretism should not give the impression that Java is an area of religious conflict. The different belief systems have been molded into a coherent whole, and the various public rituals (like the calendar with its simultaneous cycles of five and seven days, i.e. these coincide every thirty-five days) are thoroughly ingrained throughout the Javanese population (of course, as we know, the "Europeanized elite" frequently have different ideas). The Sanskrit classic epic Mahabharata continues to be a huge cultural influence on Java (it is easily apparent from the simple fact that many personal names are taken from that text, etc.) and the shadow puppet theatre based on episodes from this epic is one of the most distinctive and wide-spread Javanese cultural practices. The gamelan is always used to accompany these plays (wayang kulit). The classical dance forms of Indonesia are also attaining some level of popularity in the USA (you could have seen them regularly in the Rose Bowl Parade, for instance), and much of the court music was written to accompany dance. There is also a large and impressive body of surviving classical literature on various topics, usually written in verse (including a verse encyclopedia, if you can imagine...).

The gamelan orchestra, based on metallic percussion with winds and drums, is well-known to many readers. In various forms, it is ubiquitous to Southeast Asia. In Java, the full gamelan also adds a bowed-string instrument (the rebab, a name illustrative of Islamic influence) and voices. The rebab is one of the main melodic instruments of the ensemble (together with the xylophone "gender") and is often played by the senior musician. Voices consist of male and female choruses, together with soloists; however, the voices are not usually featured in court gamelan (as opposed to wayang kulit, shadow puppet theatre) and are supposed to be heard discreetly in the middle of the orchestral sound. In these abstract pieces, the words are largely secondary to the music itself.

This list of recordings is devoted to court gamelan. There are four royal courts (kratons) in Central Java, two each in Surakarta (Solo) and Yogyakarta. Returning briefly to history... when the Dutch took over the Southeast Asian trade and established themselves in Java (Sunda, actually), their policy was not to destroy the royal court, but to isolate it. In other words, they did everything they could to remove any political influence from the sultans, but allowed the court to remain as a cultural institution (which had always been a large part of its role, perhaps analogous to the Chinese Emperor). Much later, the court (originally in Solo) divided into four, due to philosophical differences (of aesthetic) in the royal house, and with encouragement from the Dutch. The kratons continue to serve as cultural and educational institutions, and house the classical music tradition of Java. Each court has a huge roster of musicians and an extensive collection of historical instruments; today many of these musicians also have jobs outside their kraton, but this was not true in the past. Despite what any of this discussion might imply, the music itself is extremely coherent. It shows no sign of mixed objectives, but is rather a "pure" style. The repertory is vast.

There are two scales in Javanese gamelan music, "slendro" (pentatonic) and "pelog" (heptatonic-pentatonic). Tuning is not standard, rather each gamelan set will have a distinctive tuning. A complete gamelan consists of a pair of sets, one tuned in each of the scales and intended to be played together in many instances. Different gamelan sets have different sonorities, and are used for different pieces of music; many are very old, and used for only one specific piece. Musical forms are defined by the rhythmic cycles. These consist of major cycles subdivided by smaller cycles, each marked by the striking of successively smaller gongs. The melodic interplay takes place within this framework (technically called "colotomic"). There are also distinct melodic modes ("patet") within the division of scale, but my knowledge of this is insufficient to attempt any sort of detailed explanation.
