Abstract:A recent suggestion that the entire population of the Javan
Rhinoceros in Ujung Kulon National Park was annihilated by the effects of the
eruption of the Krakatoa in 1883 is investigated. Based on a review of
contemporary reports, it is shown that people survived the waves and remained
settled in one village until 1906 when it was evacuated during a plague of
tigers. The first report of a rhinoceros
in the peninsula of Ujung Kulon dates from 1857 and the animals were
occasionally reported from the area afterwards. There is no indication from the available estimates and sightings that
rhinos were exterminated in the area. Ujung Kulon has been a protected area since 1921. Rhino numbers ranged upwards to about 40 or
50 for most of the period until 1949. The population of Rhinoceros sondaicusis not a new founder population established after the eruption of the Krakatoa
in 1883.
Keywords: Conservation, founder

Introduction
The Javan
Rhinoceros (Rhinoceros sondaicus Desmarest, 1822) (Mammalia:
Rhinocerotidae) is one of the rarest mammal species on earth, which survives
only in the Ujung Kulon National Park on the western tip of Java and in the Cat
Tien National Park in the southern part of Vietnam. Fernando et al. (2006) recently studied the
genetic diversity of the Javan Rhinoceros by analysing the DNA obtained from
dung samples of both these widely separated populations. In line with previous taxonomic findings by
Groves & Guérin (1980), it was found that the two populations represent
separate evolutionary significant units which shared a common ancestor from
around 2 million years ago to 300,000 years ago. As part of their investigations, they
suggested that the catastrophic explosion of Krakatoa in 1883 not only
annihilated the human settlements in Ujung Kulon, but also wiped out the rhinos
from the peninsula (Fernando et al. 2006: 445). In their opinion, the remaining rhinos in Ujung Kulon are likely to be
the progeny of animals which invaded the area after 1883 from other parts of
southern Java.
We investigate
the historical evidence of this scenario proposed by Fernando et al.
(2006). There are only limited data
regarding the rhino population in western Java, but we will place the existing
estimates in the perspective of the conservation and management of Ujung Kulon
from the first reports of rhinos in the area from around 1850 to 1949. We will also look at the information on human
settlements on the peninsula around the time of the eruption of the Krakatoa,
to assess how they were affected by this event. The wide time period is chosen to gain insight in the possible changes
in the rhino population, as well as to document a significant period in the
history of nature conservation in Indonesia and on the island of Java in
particular.
Fernando et al.
(2006: 447) quite rightly state that conservation and management of the two
last remaining populations of Rhinoceros sondaicus require “an
understanding of its demography, ecology, behaviour, genetics, and their
interactions.” This species of
rhinoceros has always been rare, or, possibly more accurately, sightings have
always been uncommon throughout its large former range (Groves 1967). In comparison to the other species of
rhinoceros, the biology of the Javan rhinoceros has been quite exceptionally
well studied and documented, mainly through the efforts of three pioneers in
nature conservation.
A comprehensive
review of all knowledge about the Javan Rhinoceros was published in Dutch in
1941 by Henri Jacob Victor Sody (1892-1959). Sody studied the systematics and biogeography of Asian mammals during a
period of 30 years (1918-1947) spent on Java teaching at the secondary
agricultural school in Bogor (Becking 1989). As a result of the Japanese occupation of Indonesia at the time, very
few copies of this book remain, probably no more than ten in total. It was important enough to be translated into
German and this version is widely available (Sody 1959).
Ujung Kulon has
for many years been a priority for nature studies by Andries Hoogerwerf
(1906-1977), who from 1931 to 1937 worked in the Botanical Garden in Buitenzorg
(Bogor) as Head of the Department for Hunting and Nature Conservation, and from
1937 onwards he was in charge of nature conservation in the Dutch East Indies. Hoogerwerf made numerous visits to Ujung
Kulon during the 1930s and 1940s. His
observations were described in many smaller articles highlighting the plight of
the fauna of the reserve, as well as in his magnum opus, ‘Udjung
Kulon, the land of the last Javan rhinoceros’, which will long remain
critical to all further surveys in the area (Hoogerwerf 1970). Further studies on the ecology and behaviour
of the Javan rhinoceros in Ujung Kulon were undertaken by the Swiss biologists
Rudolf Schenkel (1914-2003) and his wife Lotte Schenkel-Hulliger (Schenkel
& Schenkel 1969; Schenkel 1971).
Ujung Kulon
before 1883
On 19 January
1752, the Swedish chaplain and amateur naturalist Pehr Osbeck (1723-1805), who
attended lectures by Linnaeus in Uppsala, anchored in Meeuwenbaai (Mew Bay,
West Java) on his return from China. He
recorded that it was hazardous to reach the shore due to the abundance of
corals. Walking from the beach inland, he found the forest very thick, wet, and
dangerous due to the abundance of tigers and other carnivores (Osbeck 1765:
352-353). Apparently, he did not
encounter any of these animals, nor does he mention the presence of
rhinos. Osbeck was correct to state that
the bay was then the usual anchoring place for ships travelling through the
region. For instance, Captain James Cook also passed near the shore of Prince’s
Island (Prinseneiland) on board the Endeavour on 1 October 1770
(Hawkesworth 1783: 301).
The extreme
western tip of Java remained unexplored until the start of the nineteenth
century. In 1807, there was an attempt
to construct a new naval port on the shore opposite Pulau Peutjang (Meeuweneiland)
under orders of the Governor-General Herman Willem Daendels (1762-1818), but
the work was abandoned when the men succumbed from breathing noxious vapours
(Hoogerwerf 1970: 9). In 1816, Captain
Basil Hall (1788-1844) anchored in Mew Bay, and provided the following
narrative: “While the boats’ crews were busily engaged in filling the
water-casks, one or two of the officers endeavoured to penetrate the woods in
search of game; but the jungle was found everywhere completely impervious. The
whole forest rung with the discordant screams of birds, principally of the
parrot tribe, dressed in a plumage as brilliant and beautiful as their notes
were unmelodious. In every other respect, the scene was perfectly undisturbed,
nor could there be distinguished a single trace of inhabitants, or any symptom
to tell that the spot had ever been visited since the creation” (Hall 1826:
6).
Two expeditions
organised in 1853 and 1854 by the “Koninklijke Natuurkundige Vereeniging”
(Royal Society for Natural History) to explore the coal seams near Muara
Tjukuja (Meeuwenbaai) did not lead to any further development. At that time, and for a considerable period
afterwards, there was only one settlement in the region, a kampong (village)
called Djungkulan or Djungkulon near this bay (Maier 1853; Smit 1854). It is likely that visitors to the area rarely
penetrated inland from the coast into the tiger-infested forests which have
been characteristic for this peninsula (Hoogerwerf 1970: 11).
The rhinoceros
was not reported in the area until Arthur Adams (1820-1878), naval surgeon and
conchologist, gave an account of his visit to Mew Bay (Meeuwenbaai) in his
voyage on board the Actaeon in 1857. He mentioned a little waterfall, which then existed about 2 miles east
of the only village. He stated that
“there is a legend among the sailors of a rhinoceros having charged a party
watering here some time previously.” Although this could have been an unfounded rumour, he also found the
ground “literally ploughed up by the tracks of these unwieldy pachyderms”
(Adams 1861: 7328).
A lighthouse was
first built in 1877 on Java’s westernmost point, Tanjung Layar, and replaced by
a second structure in 1897. According to
Kal (1910), the settlement consisted of the lighthouse, a residence for the
supervisor and quarters for the workers. It was about 15 minutes walk from the beach, connected through a sandy
road which was 2-3 meters wide and fringed by shady trees and a few coconut
trees. There were six wells containing
good drinking water. The European
graveyard then had three graves. The village of Djungkulan near the lighthouse
also had two small satellites called Tjikula and Rumah Tiga in the 1870s. There was relatively little human presence in
the whole peninsula.
The effects of
the Krakatoa eruption in 1883
When the
Krakatoa erupted on 27 August 1883, huge tidal waves ran across the Sunda
Straits towards the coast of Java. According to Verbeek (1885), who gathered
the available information on the disaster from local sources, most of the
people living in the villages in Ujung Kulon gathered at the lighthouse (about
40m) and survived the eventful days. He
suggested that all available information showed that the waves were less than
15m high when they reached the Javanese coast and penetrated less than a
kilometre from the northern shore.
Although the villages and the surrounding lands in Ujung Kulon were inundated,
there was relatively little long-term effect on the wildlife.
About 20 years
later, Veth (1875: 247) stated that Rumah Tigah in the bay behind Pulau
Peutjang was then the only settlement in Ujung Kulon. According to Kal (1910: 139), the village of
Djoengkoelon (Djungkulon) opposite Meeuweneiland, with about 40 houses, had
been devastated during the eruption, but people had returned there afterwards,
only to leave permanently due to a plague of tigers. Similarly, Halewijn (1933) mentioned that the
village of some 500 people which existed near the mouth of the Tji Boenar (Tji
Bunar) had been abandoned in 1906 due to a plague of tigers. According to Hoogerwerf (1970:11), the whole
of Ujung Kulon was evacuated at the beginning of the 20th century, except the
small post at the lighthouse. This
measure was taken by the government to protect people from the regular
outbursts of malaria and dysentery, as well as on account of the number of
tigers in the area. Possibly another
motive was to facilitate the creation of a new nature reserve.
There is then no
evidence that the eruption of the Krakatoa directly influenced the number of
people living in Ujung Kulon. Besides
the lighthouse, there was only one relatively small village. This was abandoned as late as 1906 due to
pressures on the government to provide good living conditions in the province.
The rhinoceros
was widely distributed over the island of Java until well into the 20thcentury and its distribution included the province of Bantam, which borders
Ujung Kulon. Rhinos were often shot in the southern part of Bantam in the early
part of the century (Sody 1941: 50). Van
Weede (1908: 379) hunted rhinos with W. Boreel in 1908 at CikepuH, east of
Pelabuhan Ratu on the south coast, stating his regret that the numbers were
diminishing. In 1914, a large female
rhinoceros was shot (after obtaining a special permit) in South-West Bantam by
V. de Sturler, who donated the specimen to the Zoological Museum in Buitenzorg
(Sturler 1915: 63). It is widely
accepted that the last rhinoceros in southern Java was shot at Tasikmalaja by
P.F. Franck for the Museum at Buitenzorg on 31 January 1934 (Appelman &
Franck 1934).
Special
expedition were always required to
observe rhinos in Ujung Kulon. Sijfert
Hendrik Koorders (1863-1919) was the first president of the “Nederlandsch
Indische Vereeninging voor Natuurbescherming” (Society for Nature Conservation
in the Dutch East Indies) founded in 1912. He visited Ujung Kulon from 25 June to 6 August 1892 and mentioned that
the peninsula was covered with primary forest and was uninhabited, except for
the area around the First Point. He
encountered fresh spoor of rhino, besides many deer, tigers and banteng
(Koorders 1916). There are three
references to the presence of rhinos in Ujung Kulon from the early years of the
20th century. Alfred Ernst
(1908: 24) visited the region in 1906 and records that tigers and rhinos were
still plentiful. Hugo Bremer went on a
hunting expedition near Welcome Bay in 1908, and soon found “eine Menge Spuren
der Dickhäuter, die in dem weichen Boden große runde Vertiefungen hinterlassen
haben” (Bremer 1908: 59). Kal (1910: 139,
cf. Sody 1941: 50) also mentioned that rhinos were present on the peninsula
Djoengkoelon.
The killing of
rhinos on the island of Java was totally prohibited in an ordinance of 1909 (Staatsblad
van Nederlandsch Indië, no. 497, 23 October 1909; Sody 1941: 50). The maximum sentence for this offence was 8
days imprisonment or a fine of 100 guilders. Although poaching continued, rhinos increased along the South coast, and
were particularly numerous in Ujung Kulon (Kerkhoven 1926). In 1910, a local association of big-game
hunters called “Venatoria”, petitioned the government to acquire exclusive
hunting rights in Ujung Kulon, whereby it undertook to follow all regulations
strictly and manage the area. The
“Nederlandsch Indische Vereeninging voor Natuur-bescherming” was not averse to
this proposal, because it would give a measure of stability and ensure some
form of protection. However, the
petition was denied by the government (Hoogerwerf 1970:13).
Eekhout (1911)
stated that six permits for mining exploration were granted in February 1910
for both Prinseneiland (Pulau Panaitan) and the peninsula Djoengkoelan. The
prospecting was done by the “Maatschappij voor Mijnbouwonderzoek Welkomstbaai”
(Company for Mining Exploration in Welkomstbay) founded in Batavia. In August
1910, Eekhout was sent to explore the possibilities, and he reported that,
besides at the lighthouse, there were no people resident on the peninsula. The mining appeared unprofitable and the
project was abandoned without further intrusions.
In September
1913, a number of leading citizens of Batavia, including the Public Prosecutor,
went on a holiday trip to Ujung Kulon, which was said to be the richest in game
on the whole island (Hoogerwerf 1970: 12). A banteng was shot, and tracks of rhino were found along the Tjigenter
and near the mouth of the Tjitjangkok. The guides estimated that only four or five rhinos were left in the
area, because they had been decimated by the Chinese, but one of the guides
himself would have killed 11 of them. The whole area was uninhabited, because the villages had not been
rebuilt after the explosion of the Krakatau.
Ujung Kulon as a
nature reserve (1921-1937)
Ujung Kulon was
declared a “Natuurmonument” (Nature Reserve) on 16 November 1921 by Government
Decree No. 60 (Staatsblad Nederlandsch Indie, no. 683). This automatically entailed the introduction
of a total ban on killing or trapping any animal species and on the
establishment of human settlements. At
the time, however, there was no supervision to ensure that the laws were
adhered to, and it was not forbidden to enter the forest.
The presence of
the rhinoceros in the nature reserve was well-known at the time, but estimates
of the size of the population were less reliable. Sody (1941: 54-55) quotes a letter dated 8
July 1932 received from Mr. Elbers, the administrator of an agricultural
enterprise in Tjikandi Ilir near Serang. Elbers had regularly visited South Bantam and Ujung Kulon up to 1929 and
had observed rhinos in the swampy area of the nature reserve between Tjikawoeng
and Tjihaneuleum, as well as along the Tjigenter, Pamegeran, Tjitelang, Njioer
and Moeara Oedjoeng Koelon (near the lighthouse). Although he estimated that there were about
100 rhinos at the time, he predicted their extermination because Chinese and
Indonesian poachers had uncontrolled access in the absence of professional
hunters. The same estimate of 100
animals was repeated by the (anonymous) Assistant-Resident of Lebak in a letter
dated 11 May 1932 to Sody (1941: 55).
When Halewijn (1933)
visited Ujung Kulon at the end of July 1931, he found several older rhino
tracks, both near the lighthouse and elsewhere. In 1935, rhinos occurred in the swamps south of Java’s third point, as
well as to the east of the reserve in the vicinity of Pradana on the Peperbaai
(Hoogerwerf & van Steenis 1936: 48, 49). Franck (1935: 48-49) stated that the number of rhinos in Ujung Kulon
could not be properly estimated for three reasons: visits to the reserve by Europeans
were rare and generally too short; visitors did not explore those forests where
rhino live during the day; and the forest personnel were not trained to assess
the situation. When he compared the
experiences of people who had been to Ujung Kulon between 1912 and 1935, he
found that most had kept to the path which runs south from Meeuwenbaai. Rhino tracks had been found all over the
reserve. He hoped that the current
population would increase with proper management and protection, and suggested
that at the time there were about 25-30 animals, possibly six males and 19-23
females.
There is regular
evidence that rhinos and other animals were poached in Ujung Kulon during the
1930s. In February 1930, a Chinese man
was found to have shot at least two rhinos within the area of Ujung Kulon (Sody
1941: 53, after Bataviaasch Nieuwsblad 25 February 1930). Although he was apprehended, he was released
on a legal technicality (Bernard 1930; Leefmans 1931). In 1933 there were further reports of rhino
poaching (Endert & Dahler 1935: 15; Sody 1941: 55). On a visit in August 1934, Jan Scipio de
Kanter, retired resident of Bantam, found clear signs of poaching activity in
the area of the Tjikarang. When he had
previously visited in October 1932, he had mentioned in his report that the
police had solved nine cases of rhino poaching in the preceding 12 months
(Hoogerwerf 1970: 63).
In 1936, rumours
in the local media highlighted that a large number of rhinos had been illegally
killed in Ujung Kulon in the last quarter of 1935. A reward of 250 guilders for information
leading to an arrest offered by Johannes Cornelis Ligtvoet, Assistant-Resident
of Pandeglang, had no result. Through information from a Chinese rhino poacher
finishing his prison sentence and an intensive police investigation, many
poachers were arrested, including the Wedana (district chief) of
Tjibalioeng. The official enquiry by
Ligtvoet (report dated July 1936) found that a poaching gang had succeeded in
killing 15 rhino from October 1935 to April 1936 (Sody 1941: 56; Voogd &
Siccama 1939: 51; Hoogerwerf 1970: 64). One of the poachers was sentenced to 3 years in prison (Endert 1936:
18). The whole episode was brought
before the “Volksraad” (National Assembly) in questions by the politician Jan
Verboom (Voogd & Siccama 1939: 51 with reference to the Appendix of the Handelingen
van den Volksraad betreffende het zittingsjaar 1937-1938, p.8; Sody 1941:
56 following Algemeen Handelsblad, 4 December 1936). A subsequent nationwide investigation into
the sale of rhino products as medicine found that the trade was flourishing all
over Java. It was also decided to post
five police officers at Karang-Randjang on the isthmus to the peninsula. An extensive intelligence system was
organised covering much of western Java (Voogd & Siccama 1939: 51-52).
Hoogerwerf
visited Ujung Kulon in January 1936, paying attention to the security of the
area. He suggested that there could
never be adequate protection without the availability of a boat to aid in
patrols (Hoogerwerf 1936). Requests for
a motor launch to improve access and for additional guards were turned down by
the government authorities in 1932 and 1936 (Hoogerwerf 1970: 16).
On 13 September
1937, one of the local newspapers in Java (Het Nieuws van den Dag voor
Nederlandsch Indië) published a photograph of four skulls left in Ujung
Kulon by poachers, but there is no report of the men ever being found (Sody
1941: 57, fig. 12).
Ujung Kulon as a
game sanctuary (1937-1949)
Ujung Kulon was
declared a “Wildreservaat” (Game Sanctuary) covering an area of 28.600 hectares
by Decree No.17 of the Governor-General on 24 June 1937 (Staatsblad
Nederlandsch Indië, no. 420). The
eastern boundary was changed to effect a link with the forest reserve Gunung
Hondjé. On 2 July 1938, the Director of
Economic Affairs decreed that the park would be entirely closed to visitors,
except with special permission obtainable from the Chief Forest Inspector (Besluit
Directeur Economische Zaken, No. 10040/B.W./H.I., 2 Juli 1938). Sody (1941:
58) states that in reality only the East coast was closed as part of these new
protection measures. However, a European
guard was posted at Tamandjaja on the West coast to oversee a forest guard and
boatsmen, while on the isthmus a new post was erected for two retired military
men and a guard.
Hoogerwerf
visited the reserve in an official capacity from the end of August to the
beginning of October 1937. He found that
the stock of game was satisfactory, including about 20-25 rhinos, but there was
a great lack of pasture (Hoogerwerf 1938 1970: 18; Sody 1941: 58). On two visits in 1938, Hoogerwerf (1939) saw
seven rhinos in Ujung Kulon, including at least one (possibly two) calf. A new surveillance system was devised, which
was all that was deemed necessary at the time to protect the remaining rhinos. However, the structure of management was
changed with almost immediate consequences.
In February
1939, a European poacher shot a female rhino and her calf in Ujung Kulon
(Hoogerwerf 1970: 19, 64; also reported in Java-Bode of 3 May 1939 in
Sody 1941:58 note 202). According to a
speech by Verboom in February 1940, maybe as many as four rhinos had been
poached in the previous year (Sody 1941: 58, note 202). In 1939, after the case of poaching had
become public, some improvements to the management of the reserve were
instituted, largely spearheaded by Maarten Hoek, the first forest official of
Bantam. An improved patrol system around
the perimeter of the whole reserve was instituted, old grazing grounds were restored,
and regular transport to the island was maintained (Hoogerwerf 1970:19). Due to the additional vigilance, in October
1939, five Indonesians were caught while transporting parts of a freshly shot
female rhino east of the reserve (Hoogerwerf 1970: 64).
Hoogerwerf made
several excursions to Ujung Kulon in 1941. He encountered two rhinos on 14 February 1941, and another two on 28 May
1941 on the Tjigeunteur. Tracks were
found on the shore opposite Meeuweneiland on 16 February 1941 (Hoogerwerf
1949). This visit was followed by a
politically unstable period during the Japanese occupation of Java from March
1942 to 1945. Hoogerwerf accompanied a
Japanese hunting party to Ujung Kulon from 6 to14 September 1942, partly to
ensure that no rhinos would be killed, immediately followed by a short survey
of the area with forest officials from 17 September to 11 October 1942. He found fresh tracks and signs of feeding of
rhinos at different locations, including some on the beach of both the northern
and southern shore. Three rhinos in good
condition were encountered and four times the animal was heard (Hoogerwerf
1946, 1948: 206).
He visited again
from 30 December 1942 to 29 January 1943 to take steps for further surveillance
of the reserve (Hoogerwerf 1970: 20). He
found that the personnel were rarely to be found inside the reserve, and little
work was done on maintenance of the pastures and the patrol trails. On 19 January Hoogerwerf’s people were
attacked by a couple of rhinos near the Tjitandahan river on the South coast.
Personally, he only saw rhino tracks, but those included those of a calf
accompanied by an adult as well as another group of animals (Hoogerwerf 1948:
210, 1949: 365, 1970: 21).
From July 1943
to April 1944, the forest guards submitted regular reports showing that rhinos
were regularly encountered (Hoogerwerf 1949: 367). These included the following details of rhino
sightings in 1943:
20 May - 6 June: 6 rhinos (5
males.1 female) near north coast
21 June - 19 July: 9 rhinos (7.2)
near north coast
19 July - 18 Aug: 10 rhinos (10.3)
near south coast
19 Aug - 17 Sept: 8 rhinos (8.0)
near north coast
17 Sept - 12 Oct: 11 rhinos (8.3)
near south coast
17 Oct - 6 Nov: 15 rhinos (13.2)
near south coast
Most rhinos were
found solitary or in pairs, but once an unusual group of three specimens was
recorded. From February to March 1944
the guards saw four rhinos (Hoogerwerf 1946: 207). On 29 October 1943, forest guards found the
remains of a freshly poached rhino inside the reserve lying in a mudhole not
far from the northern coast, along the Legon Penju. The owner of the gun used in the incident was
sentenced to 9 years imprisonment for illegal possession of a firearm, but the
poachers could not be apprehended (Hoogerwerf 1970: 21, 64).
The period after
the end of the Japanese occupation was chaotic and any direct management of the
reserve was impossible. From 1946 to
1950, at least five rhinos were poached (Hoogerwerf 1970:21, 64). Fortunately, during a visit to the reserve in
November-December 1950, Hoogerwerf found a good number of rhino tracks. He was certain that he saw tracks of ten
different animals, albeit no calves, but that of course had always been a rare
occurrence. Although he did not estimate
total numbers, he was happy to witness that the rhino population had not
deteriorated too much during the period of war (Hoogerwerf 1950: 55-58, 1970:
21).
Discussion
Fernando et al.
(2006: 445), as part of the discussion on genetic variability, suggest that the
“catastrophic explosion of Krakatoa in 1883, and its aftermath, in addition to
annihilating the human settlements in Ujung Kulon, would likely have
exterminated the Javan rhinos then inhabiting the peninsula. The present day
Javan rhino population probably originated from subsequent re-colonization.” However, this well-documented and carefully
written paper does not justify this statement, nor provide any reference to
another source for this conclusion. As
far as we are aware, the idea of the local extermination of rhinoceros in Ujung
Kulon and subsequent re-colonization has not before been elucidated, hence the
idea would benefit from further discussion. The historical data on the early human settlements in Ujung Kulon are
patchy, but most sources agree that, outside the immediate surroundings of the
lighthouse, there has only been one sizeable village on the peninsula during
most of the 19th century. This village was abandoned or evacuated in 1906, possibly under pressure
from the government due to the prevalence of diseases and a rise in the number
of tigers. There is no evidence that the
eruption of the Krakatoa had a lasting influence on the population of the
village, even though it obviously created great disturbance when it occurred.
The impact of
the volcanic eruption on the wildlife in Ujung Kulon is even more uncertain.
There could have been casualties, or possibly large mammals like the rhino were
able to withstand the waves. There may
have been changes in the flora caused by the salt water, but if this had any
effect on the browsers and grazers is unknown. The reports on the rhinoceros in the region have always been
sketchy. The animals were regularly
reported in Ujung Kulon, both before the eruption of 1883 and afterwards. In the literature, we are unable to find any
statement that the rhino population particularly suffered during the
period. Rhinos were sighted in Ujung
Kulon in 1892, 1906 and 1908, and of course regularly afterwards. Before the catastrophe, there were no
definite estimates of rhino numbers. After it, there were suggestions that the rhinos numbered anywhere
between 20 and 100 (Hoogerwerf 1970: 70). None of these figures was based on a long-term or intensive survey of
the entire area, hence possibly the wide range in the estimates. There is, however, in our view no evidence
that all rhinos in Ujung Kulon disappeared during the decade after the eruption
of the Krakatoa in 1883.

Nico
van Strien observing white rhino in 2006
Nico van Strien
(1 April 1946 – 7 February 2008) was a well-known biologist interested in the
birds and mammals of Africa and South-East Asia. He will certainly be
remembered for his indefatigable efforts to save the rhinos in Indonesia. From
1975 to 1980, Nico made several excursions into the remotest parts of the
Gunung Leuser National Park on Sumatra with the intention to study the ecology
of the Sumatran rhinoceros. These are elusive animals, and the only way to get
results was to design a technique to monitor their footprints and other signs.
He was able to present his data as a dissertation in 1985, which is one of the
few major studies on the subject. Nico liked field-work, but was no less at
home in libraries and museums, where he traced previous relevant publications.
He knew that sound academic research as well as effective conservation need to
be based on the experiences and observations of all generations and all
backgrounds. In his later years, Nico was active as the Asia Rhino Program
Coordinator of the International Rhino Foundation and as the Co-Chair of the
Asian Rhino Specialist Group. His expertise and leadership were remarkable. On
10 January 2008, his health weakened by incurable prostrate cancer, his friends
and colleagues received an email message from Nico to share his decision “that
whatever energy and time remains should be devoted to my family and friends.
And that I should cease all my official and unofficial functions and duties. I
want to thank you for all the things that we’ve been able to do together for
the benefit of conservation in South East Asia and in particular for the Asian
rhinos. Together we’ve been able to do many useful programs and projects and
many good friendships and professional relationships were formed.” Nico must
have struggled to write these words, just as many of the recipients much have
silently wept. We lost a fighter for nature study and conservation at the
height of his ability. He spent his last
days in Holland with his wife Tineke and his sons Maarten and Willem. Let us
continue the fight to save wildlife in Asia and Africa with similar selfless
dedication Kees Rookmaaker.
