Saola – The Discovery and Threats

Posted on 04 June 2012 by RE Team

In May 1992, Vietnamese and Foreign Biologists were taken by surprise by the discovery of three pairs of horns. These were horns of trophies killed by the local people of central Vietnam’s Vu Quang Nature reserve. The biologists were on field survey in the area. The size of the horns suggested about the existence of a large animal completely unknown to the outside world.

This discovery took the science community by shock. It was believed that after centuries of exploration by explorers across deserts, rainforests of the planet with even high technology left no place or large species unkown to the science.

After this discovery, scientists did extensive research in the area. In next few years this research led to the discovery of 20 partial specimen of this species, including three complete skin and several photos. Researchers were also able to trap the species in remotely set camera in the rain forests. With all these evidences, scientists came to the conclusion that this is a completely new species and it was named as Saola (Pseudoryx nghetinhensis).

Saola was name already local people have been referring to this animal .  Sao means Spindle and La means post. The generic name Pseudoryx , of the species refers to slightly curved, backward-sweeping horns, resembling to those Oryxes found in Africa and Arabia. Saola is very distantly related to these arid-adapted antelopes though. The specific name of the scientific name   refers to efers to the two Vietnamese provinces Nghe An and Ha Tinh close to where it was found.

The saola stands about 85 cm at the shoulder and weighs approximately 90-100 kg.   The coat is a dark brown with a black stripe along the back. Its legs are darkish and there are white patches on the feet, and white stripes vertically across the cheeks, on the eyebrows and splotches on the nose and chin. All saolas have slightly backward-curved horns, which grow to half a meter in length. The genetic analysis reveals that it is a primitive member of the cattle family.

All known locations for the species are mountainous with steep river valleys, covered by evergreen or semideciduous forests between 300 – 1800 m (1000 – 6000′), with low human disturbance.  It is only found in the foothill of the Tuong Son range. Its distribution within this known ranges is uneven and fragmented in small patches. This range occurs in the border between Laos and Vietnam. It stays in the higher elevations during the wetter summer season, when streams at these altitudes have plenty of water, and moves down to the lowlands during the winter, when the mountain streams dry up.

Even after two decades of discovery, very little known about this large mammal. In the discovery article of Saola, the team proposed  a three months survey to observe the living animal. But Even after intense efforts, scientists have not been able to see a Saola in wild in its natural setting yet! Most of the information on the Saola is gathered from photos and local people’ knowledge.

Local people have reported having seen saola traveling in groups of two or three, rarely more.  Villagers say that the ox eats the leaves of fig trees and other bushes along riverbanks. Saola mark their territories by opening up a fleshy flap on their snout to reveal scent glands. They subsequently rub the underside against objects leaving a musky, pungent paste. The saolas’ colossal scent glands are thought to be the largest of any living mammal.

Though very little known about Saola, one thing is certain that its in a very critically threatened state. In 1994 IUCN listed the species as “Endangered”. But in 2006 its given “Critically Endangered” status due to reducing population.  The animal can’t survive in captivity. All efforts to keep in captivity have failed, the latest being late August 2010.  A Saola was captured by villagers in Laos but died in captivity before government conservationists could arrange for it to be released back in to the wild.

The actual size of the remaining population is unknown and its rarity, distinctiveness and vulnerability make it one of the greatest priorities for conservation in the region. The current population is thought to be a few hundred at maximum and possibly only a few dozen at a minimum.

In April 2011, a reserve was declared to help protect saolas. The Quang Nam’s People Committee inaugurated the Quang Nam Saola Nature Reserve in the Annamite mountains along the border of Vietnam and Laos.  This recent development has created hope for this extremely rare mammal in the world.

Amazing Cave Story

Posted on 19 May 2012 by RE Team

Human race spent thousands of years inside caves in the process of evolution. The caves not only provides shelter to lives, but also home to various unique species till now. There are number of gigantic caves around the earth that have self sustaining ecosystem and create a different world inside themselves. In the modern world, the discovery of such cave is always a thrilling story, as they are normally hidden in the remote jungles or mountains lying unknowingly to humans preserving a world inside it untouched for thousands, may be millions of years.

 

The gigantic Hang Son Doong Cave - Coutesy NationalGeographic

 

Almost a year back such a spectecular cave was discovered in the Annamite Mountains of Vietnam. This cave is so huge in size that it contains a river, a  complete jungle and even its own thin clouds making the other side of the cave out of sight at times. It is large enough to accomodate a whole city with skyscrapper inside it. In fact we are talking about the largest cave passage in the world here, named as Hang Son Doong.  For decades, geologists have doubted that Vietnam could be home to some of the world’s most spectacular caves. But a large number of them were unexlored. British scientists from the British Cave Research Association, led by Howard and Deb Limbert, are the first to explore the cave. The cave is named as Hang Son Doong, means mountain river cave. Though credit of bringing the largest cave to the outside world goes to Howard and Limbert, yet the actual discovery credit of the cave goes to a local man named Hồ-Khanh.

Ho Khanh’s family lived in a nearby village and he has long story to tell about the discovery of the cave.

“I was born into a poor family. My father died, and my family had no rice fields, so I had to go to the jungle for work to support my family. Over a period of 13 years, I learnt the location of many caves in the areas I passed through.

In the rainy season of 1991, I went with two others to look for the aloe wood, which is very precious and exists deep in the jungle. It is very hard to find. We separated and I went through Hang En. The next day was raining very hard, so I looked for somewhere to stay for the night. Fortunately I found the entrance of an unknown cave. After the trip I returned home, and gradually forgot about this cave.

Mr Khanh - The discoverer of the cave

In 2006 I met the British Caving Expedition and took them to the Doong area, where they explored many caves. In 2007 I took them to the Doong area again for further cave exploration. On this trip we found Ho Nui Cave. Before the end of the trip I talked with Mr. Howard. Although we can’t speak the same language I knew that he was looking for a cave to connect Hang En, with another cave Hang Thoong, in the Tra Anh area.

I had a memory of a cave in this area, which maybe had a wind, and fog blowing from the entrance, but I couldn’t remember the location. I went off for an extra day searching for this cave, but unfortunately failed.
I didn’t want to give in. Because of my great admiration for the explorers’ abilities and their friendship, I wanted to show them this cave. In January 2008, I spent my own time and money to return to the Doong area to look for the entrance. Relying on my memory and experience, I followed the stream from Hang En, and fortunately found the big cave entrance in about half a day. I cut down some wild saplings to reach the entrance. Finally using my knowledge of the jungle, I found the best path to take the cavers to the entrance, and made it as easy as possible. It was now 2pm on the third day, so I returned to Phong Nha and waited for the expedition to return.
In March 2009 the expedition returned to Son Trach. On the first trip I really wanted to take Mr. Howard to the new cave, but another team came. At that time I was worried in case the cave was dry and not very long. But thank god, in this trip the cave length was measured at about 5k, and there was a large subterranean river. The explorers realized that this could be the largest cave passage in the world.

I believe that I have made them all especially Mr. Howard very pleased, because this is an important cave which connects the Doong area with the Tra Anh area.”

So is the story of discovery of the largest cave passage in the world. The Son Doong cave measures 262 feet by 262 feet (80 meters by 80 meters) and at least 2.8 miles (4.5 kilometers) deep. The biggest chamber of Son Doong is over five kilometers in length, 200 meters high and 150 meters wide. This discovery overtook the size of Deer Cave, which held the record of the largest cave passage previously. Deer Cave in Malaysia, is 300 feet by 300 feet (91 m by 91 m) in parts, but is only about a mile (1.6 km) long.

The Son Doong cave is located in in Phong Nha-Ke Bang National Park of Vietnam, near the Laos-Vietnam border. Phong Nha-Ke Bang area is noted for its cave and grotto systems as it is composed of 300 caves and grottos with a total length of about 70 km, of which only 20 have been surveyed by Vietnamese and British scientists. It is currently a national park and UNESCO World Heritage Site.

Vietnamese Javan Rhino is Extinct

Posted on 25 October 2011 by RE Team

In April 2010, the rangers of Cat Tien National park could not save the female Rhino that fell prey to poachers. After this killing, there were no sighting of any Rhino in the park, nor any footmarks, dung. The analysis of all the dung samples collected during 2009-2010 revealed that it was of the same Rhino that was killed in April, 2010.

The rarest Rhino in the world got rarer, according to the annual report by International Rhino Foundation (IRF).  The report declares Javan Rhino (Rhinoceros sondaicus) to be extinct in Vietnam and officially Indonesia is only country where it now exists in wild.

The Javan Rhino, also known as lesser One-horned Rhino, is ‘Critically endangered’ in IUCN Red list and not more than 44 individuals are surviving in wild as per the IRF 2010 report. All 44 individuals are found only in the Ujang Kulon National Park of Indonesia. The report says, “Sadly this year, we believe that the last Javan Rhino was poached in Vietnam’s Cat Loc Reserve. In Ujung Kulon, best survey estimates, backed up with camera-trap data, suggest that no more than 44 animals remain in the park. Of these, we suspect that there are only four or five females with breeding potential. ”

Indonesia is the last hope for the Javan Rhino, the rarest large mammal in the world. The utmost priority should be given to the protection of the existing population in Ujung Kulon and also expanding the current population to a second habitat for giving more chances of survival to the species.

Poaching is the greatest threat for the Javan Rhino. The Rhino horn brings extraordinary value in the black market which appeals the poachers easily. In China the horn believed to be cure of many ailments including heart disease, cancer, etc. This baseless believe has been killing Rhinos all over the world. The last  Javan Rhinoceros of Vietnam was killed by poachers only in April 2010.  It was shot at leg and horn hacked off in the Cat Tien National Park.

This One-Horn Rhino species was widely found in the south-east Asia region just a century back. During Vietnam war, due to easy availability of powerful weapons, Rhinos were killed in large number for their horns in Vietnam. In post war time, the species was believed to be extinct from Vietnam. But 1988, a hunter killed a Javan Rhino in the Cat Tien region of Vietnam. This gave a ray of hope and proved that the species was not extinct in the region.  This leads to a survey of the Cat Tien National Park in 1989 that found at least 15 Java Rhino specimens along the  Dong Nai River. Despite this discovery, the protection measures in the Cat Tien region was not proper and the population kept on declining majorly due to poaching. In 2000, experts pointed out that the Javan Rhino population in Vietnam might not ever recover. The population stood at just around 3-8, mostly consisting of female without any adult male capable of breeding.

In April 2010, the rangers of Cat Tien National park could not save the female Rhino that fell prey to poachers. After this killing, there were no sighting of any Rhino in the park, nor any footmarks, dung. The analysis of all the dung samples collected during 2009-2010 revealed that it was of the same Rhino that was killed in April, 2010. This is how the story of Javan Rhino ends in Vietnam. The Rhinos in Cat Tien region was a subspecies of Javan Rhino, Rhinoceros sondaicus annamiticus , now extinct. Despite of various protection efforts by various organization this rare species also became the victim of human activities. Very unfortunately the Vietnamese Rhino joined the long list of similar animals that vanished from the beautiful nature.

One of the very scary fact about the Javan Rhino is that captive breeding has not been successful for the animal in zoos till now. There is no captive population in existence to support the wild population. So, now all eyes will be concentrated on the Indonesian Javan Rhino.

The Mystery of Hoan Kiem Turtle

Posted on 11 January 2011 by RE Team

This is a story of a giant turtle species that is more than 200 Kg in weight and more than 2 meter in length could keep itself unknown to human eyes for more centuries. Even in 21st century, this species is a mystery and viewed by humans a few number of times only. This could even be the largest fresh water turtle in the world. 

Almost 500 years from now, a King of Vietnam found a giagantic holy turtle during a cruise on a lake called Luc Thuy(Green Lake) near Hanoi. There is a mythical believe that the turtle told the King to return the sacred sword that he had gotten from Kim Qui, the Golden Turtle God and had helped him defeat the northern Ming aggressors returing peace to the region. The king unsheathed his sword and threw it to the turtle. The turtle took it and dove away. The king was none other than  Le Loi, also known as Le Thai To, the founder of the Le Dynasty in Vietnam, under whom the Chinese had accepted Vietnam’s independence. Later the king renmaed the lake as Hoan Kiem” (Lake of Returned Sword). For hundreds of years, people couldn’t discover any turtle like reptile in that lake, until when a giant turtle was actually captured late 20th century. The giant turtles mysteriously kept themselves away from the human eyes for centuries!

The story of the king Le Loi has been passed down from generation to generation and recorded in history books, and there were no real evidence of what the giant reptile may have looked like until 1967. It was the year when Vietnam war was on its peak. Ha Noi Food company caught a giant turtle from the lake. The turtle weighed about 200 kilos and was about 2 metres(6 ft 3in)[ long. The company was going to sell the meat, but someone alerted the Ha Noi People’s Committee and the then mayor Dr Tran Duy Hung ordered them to stop the sale. Unfortunately the turtle died on June 2, the same year because of mishandling. It was later stuffed and is now on display at the Ngoc Son Temple which is situate on the northern shore of the lake.

But after the single catch, the turtle was hardly ever viewed by the common people. Mysteriously the giant turtle shy away from revealing itself inthe small shallow lake, measuring 200 meters wide, 600 meters long, and only two meters deep.  But on March 24, 1998 an amateur cameraman caught the creature on video, conclusively proving the elusive creatures still survived in the lake. Apart from this photography, few local researchers done extensive study of the turtle too.
Ha Dinh Duc, one of the best known local biologists who has done extensive research on the turtle for decades. He  teaches in the Biology Department of the School of Natural Sciences in Vietnam. He gave the Hoan Kiem turtle its scientific name, Rafetus leloii, after the King Le Loi’s name.

Duc believes that the species could be related to the trionychidae species, Rafetus swinhoei, also known as the Shanghai soft-shell turtle, a critically endangered species found in China. There are only two known turtle of this species in captivity in China. Another one is believed to be in Dong Mo Lake near Hanoi. He has studied and preserved anything related to soft-shell turtles. He also studies the aquatic conditions and life forms in Hoan Kiem Lake which may affect the rare species.

“I believe the turtle living in the lake now is the very one that took away King Le Loi’s sword, as this species can live as long as 500 or even 700 years,” Duc says. According to him this species is near to extinction. He also explains that the turtle that lives in Hoan Kiem Lake can be recognised by the white spot on his head and a tendency to turn left when he swims.

Duc , who also keeps around 300 -400 collected photographs of the turtle, says  “The problem is we do not know how to test Rafetus Leloii’s sex. Moreover, he is too old and fragile for any testing.”

Vietnamese belive that over the last two millennia, the turtle deity is said to have helped design fortifications, thwart enemy armies and produce a number of enchanted weapons.

In 1995, the Ha Noi People’s Committee turned down an offer from Peter Pritchard, a researcher from the Archie Carr Centre for Sea Turtle Research, University of Florida to study the lake’s turtle . The authorities declined the request for joint-research efforts on the grounds that it is a sacred creature closely related to the soul of the Vietnamese people.  Similarly The World Wildlife Fund for Nature, agrees and does not finance any programs to study the species.

Similar to Duc, another local researcher, Ngo believes that there are actually five turtles living in Hoan Kiem Lake. Ngo started paying attention to the turtle when he first glimpsed of a sighting in 2002. His new theory has shocked local people, but like others he also believes the turtles in the lake are supernatural creatures. Ngo said he has been lucky to witness 40 of the 60 recorded times the Great Turtle has surfaced since 2003.

Though, very little bit of research is going on this turtles, one thing is sure that the turtle is threatened to extinct and Lake’s conditions are getting worse day by day. Pollution and illegal fishing  in the lake is threatening the life of the Hoan Kiem Lake turtle. Another threat is coming from a notorious invasive species – red-eared slider turtle in the lake.

Duc said he has warned against the invasion of red eared sliders in Hoan Kiem Lake since 2004 but local authorities have taken no action against the problem.

“City leaders should discuss the issue thoroughly before launching a long-term plan to protect the giant turtle,” he said.

Many Vietnamese people have the habit of releasing animals, including red eared sliders, into the wild to pray for good luck, an action that has been severely criticized by conservationists.  The  red eared slider turtles are outcome of the same activity only.

We hope the turtles will be reseached well and also preserved. None knows it could be last one who is representing an unique species of  the planet.
