Crude tanker storage fleet off Singapore points to stubborn oil glut

Today Online 21 May 16;

SINGAPORE — Prices for oil futures have jumped by almost a quarter since April, lifted by severe supply disruptions caused by triggers such as Canadian wildfires, acts of sabotage in Nigeria, and civil war in Libya.

Yet flying into Singapore, the oil trading hub for the world's biggest consumer region, Asia, reveals another picture: that a global glut that pulled down prices by over 70 per cent between 2014 and early 2016 is nowhere near over, and that financial traders betting on higher crude oil futures may be in for a surprise from the physical market.


A graphic from Marine Traffic. Each arrowhead represents a moving ship, while squares indicate anchored or moored ships.

"I've been coming to Singapore once a year for the last 15 years, and flying in I have never seen the waters so full of idle tankers," said a senior European oil trader a day after arriving in the city-state.

As Asia's main physical oil trading hub, the number of parked tankers sitting off Singapore's coast or in nearby Malaysian waters is seen by many as a gauge of the industry's health.

Judging by this, oil markets are still sickly: a fleet of 40 supertankers is currently anchored in the region's coastal waters for use as floating storage facilities.

The tankers are filled with 47.7 million barrels of oil, mostly crude, up 10 per cent from the previous week, according to newly collected freight data in Thomson Reuters Eikon.

That's enough oil to satisfy five working days of Chinese demand, suggesting recent supply disruptions — which have mostly occurred in the Americas, Africa and Europe — have done little to tighten supply in Asia as Middle East producers keep output near record volumes in a bid to win market share.

"The volumes of oil stored at sea in South East Asia — predominantly Singapore and Malaysia — appear to have increased significantly," said Mr Erik Broekhuizen, Global Manager of tanker research and consultancy at New York-based shipping brokerage Poten & Partners. "The current volumes are the highest for at least the last five years."

Many participants in the physical market dispute recent notes from financial players like Goldman Sachs that forecast a further rise in crude futures.

"There has been quite a bit of bullishness from hedge funds in recent months, betting on higher oil prices, and even the analysts at Goldman Sachs have recently turned more bullish on oil prices," said Mr Ralph Leszczynski, head of research at ship broker Banchero Costa.

"Prices are unlikely to rise too much as the specter of glut is still there," he said.

STORING AT A LOSS?

In fact, the need to store oil is so strong that traders are calling up banks to finance storage charters despite there being no profit in keeping fuel in tankers at current rates.

"We are receiving unusually high amounts of queries to finance storage charters," said a senior oil trade financier with a major bank in Asia.

"These queries come from traders fully aware that they will not make a profit from storing the oil. This isn't a trade play, it's the oil market looking for places to store unsold fuel," he added.

A trade financier at a European bank said there had been a "spike in interest from oil traders to finance their storage needs" since the start of the year as onshore facilities were almost full.

Both bankers declined to be identified as they are not allowed to speak to the media.

Storing oil on ships can be profitable when prices for future delivery of crude are higher than in spot market, a term structure known as contango, as long as future prices are high enough to offset tanker charter costs.

But the one-year contango for Brent crude futures has collapsed from US$7.60 (S$10.50) per barrel in January to just US$4, far below the US$10 that traders say is currently required to make floating storage financially attractive.

At a charter cost of more than US$40,000 a day for a Very Large Crude Carrier that can store 2 million barrels, the contango is nowhere near steep enough to make it profitable to store oil on tankers for sale at a later date.

"Floating storage is unattractive economically, given the current term structure in crude futures," BMI Research said this week.

Despite this, BMI said that "the volume of crude in floating storage has risen sharply in recent months," adding that the phenomenon was global, with floating storage up 19.5 percent between the first quarters of 2015 and 2016.

"There is clearly still far too much physical crude going around for the glut to be over," said the European oil trader after flying in to Singapore. "And the paper market seems blissfully unaware of it."

Malaysia: Rains came but dams still at critical level

ROYCE TAN The Star 23 May 16;

SERDANG: Water rationing will continue in Mersing and Kota Tinggi despite most dams in critical areas showing an improvement in the level due to rain the past week.

National Water Services Commis­sion (Span) CEO Datuk Mohd Ridhuan Ismail said the rationing would continue until June 15 as the level at the water treatment plants there was still below the critical mark due to insufficient raw water flowing into the plants.

“Water levels at the Lok Heng and Sungai Gembut treatment plants are seeing an increasing trend.

“We hope the rain continues so that the situation will be better.

“The level at the Bukit Merah dam has risen significantly.

“As of Friday, the level was at 8.10m or at 74.8% capacity,” he told reporters after flagging off the Thirsty Runner 2016 here yesterday.

The Timah Tasoh dam in Perlis was at 26.18m (13.3%) and the Congok and Layang dams in Johor were at 3.77m (10.35%) and 19.12m (15.1%) respectively.

He also advised Malaysians to save water as the country’s usage per capita was at 211 litres compared to the world’s standard usage at only 150 litres.

On the logging of the Ulu Muda forest reserve in Kedah, which is also an important water catchment area, Mohd Ridhuan said both water and timber sources were under the purview of the state go­vernment.

“I’m sure that they are doing it wisely because the catchment area is part and parcel of Kedah’s water source as well,” he said.

“It’s the state government’s prerogative to monitor the situation.”


Water rationing ends for Felda Lok Heng residents
YEE XIANG YUN The Star 23 May 16;

JOHOR BARU: Residents staying at Felda Lok Heng in Kota Tinggi will be relieved to know that the scheduled water supply exercise for the area ends today.

SAJ Holdings Sdn Bhd Corporate Communications chief Jamaluddin Jamil (pic) said that this was following the increase in water levels at Sungai Sedili Kecil, which supplies water to the Lok Heng water treatment plant.

He said that the water level had reached 2.67m compared to the critical level of 1.5m recorded previously which warranted a scheduled water supply exercise to be carried out.

“This puts an end to the exercise, which began about a month ago and water supply has resumed regularly,” he said in a statement here on Monday.

The settlement, which has more than 18,000 consumers, was among the areas in Kota Tinggi and Mersing affected by water cuts on 85,000 domestic and industrial consumers since a month ago.

However, Jamaluddin said that areas receiving water supply from the Sungai Gembut, Tenglu and Sungai Mersing water treatment plants would still experience scheduled water supply for the time being.


Cloud seeding must go on in Penang
The Star 23 May 16;

GEORGE TOWN: The water situation in Penang is still not safe as the level at the dams has not reached 60% even with the recent cloud seeding operations.

Penang Water Supply Corporation Sdn Bhd (PBAPP) chief executive officer Datuk Jaseni Maidinsa said that cloud seeding should continue until the effects of El Nino taper off at the end of June.

“Both the Teluk Bahang and Air Itam dams must reach the 60% mark. Right now, it’s hovering at around 50%,” he said when commenting on the recent cloud seeding operation which was successfully carried out on Friday in the northern states.

He said the water levels at the Muda and Beris dams in Kedah were presently around 30%.

A statement on the portal of the Science, Technology and Innovation Ministry revealed that cloud seeding had brought rain to the Timah Tasoh dam in Perlis, the Beris and Ahning dams in Kedah and the Teluk Bahang and Air Itam dams in Penang.

“The Federal Government should not let up on the cloud seeding ope­rations as the dry weather is expected to continue throughout June,” said Jaseni.

He added that if cloud seeding was stopped now, the level in all the dams would drop and it could create a major issue early next year even if it rained after June.

Indonesia: Lake Toba ecosystem badly needs protection

Erika Pardede Jakarta Post 22 May 16;

The government is now working on the establishment of a tourism authority for Lake Toba in North Sumatra as part of its program to turn the famous lake into one of the country’s major tourist destinations.

At present, the public can now enjoy newly opened direct flights between Soekarno-Hatta International Airport and Silangit Airport, near the lake. A toll road will also be built to shorten the travel time to reach the lake overland.

People will soon witness the rise of mass tourism at Lake Toba, Samosir Island and the seven regencies that share the lake. What will the impact of this tourism development be? Many people are waiting curiously, hoping that development will improves their lives. Meanwhile others are calling for a prudent approach in developing the plan.

The Lake Toba ecosystem and its surrounding area serves the people living in the area. It provides abundant fresh water. Lake Toba is recognised as the largest permanent lake body in Southeast Asia.

The basin and catchment area, through farming and fishing, supplies food to the community, whilst a forest provides wood and various herbs. For more than 20 years, two hydropower plants in Siguragura and Tangga have been supplied with water from Lake Toba.

The Lake Toba ecosystem services, in fact, go beyond those basic needs. Beside all those benefits, the lake ecosystem also plays a crucial role in regulating the water flows and water regime.

Like other lakes throughout the globe, the ecosystem of Toba also helps to regulate the atmosphere and climate, and dampen environmental disturbances such as storms and floods. It helps as a biological control mechanism to decrease destructive populations.

Moreover, the lake ecosystem also supports the process of soil formation, photosynthesis, pollination and nutrient cycling. Those processes support and affect the ability of the ecosystem to maintain its provisional processes and services.

Last but not least, Lake Toba provides cultural, spritual, recreational and aesthetic benefits for people. Batak tribes in the area are still connected to and maintain their traditional culture, handed down from generation to generation.

There are lots of myths among the native people and they practice traditional rituals. Being buried in their homeland Toba, the land of their ancestors, is something most Batak people desire. They preserve tombs and cemeteries contain graves from ancient times to the present.

Population growth and development over the past two decades has affected the ecosystem of the lake. Its catchment area faces an environmental crisis characterized by widespread deforestation, drought, water level decline, water-quality degradation, invasive species and loss of biological diversity.

Developing the lake into a major tourist destination has caused concerns about its impact on the ecosystem. The tourism industry brings financial gain, and a location becoming a tourist destination brings both direct and secondary impacts, affecting tour operators, tourist enterpreneurs, local residents and the central government.

However, besides financial benefits, it can also have a negative impact on the environment.

Many studies have revealed that tourism can put pressure on natural resources, local resources and create land degradation. Human activities that cause habitat destruction and widespread deforestation has affected the slope and land around the lake. Tonnes of logs are daily extracted from the forest.

There has been significant land-use conversion for industrial and residential development. Later on, tourism will demand a large amount of land to support the need for hotels, recreation areas, resorts and parks. This will further shift the land-use pattern from predominantly forest and farmland to infrastucture that supports tourism.

Currently, intensive agricultural practices and floating-cage aquaculture in the lake have led to contamination, both from a chemical used in agricultural practices and fish food.

The spreading of hyacinth water plants over the lake surface is an indication of a change in water quality suggesting the water has been affected by a heavy pollutant.

The high concentration of tourists can also cause forms of pollution such as air, water, noise and aesthetic pollution; besides increase of solid waste, sewage and littering. Tourism activities can lead to the loss of biological diversity, and in the long run at the global level will contribute to the depletion of the ozone layer and climate change.

Finally, although Toba Land is not new to tourism, the goverment‘s plan will big changes to the area. Is the community ready for such a big leap to support today’s style of tourism. Disruption of cultural practices may also occur, and people will need to adapt to the new situation.

The development of Lake Toba as a tourist destination should also consider its negative impacts on the ecosystem.

Malaysia: Sabah poachers persist despite crackdown

RUBEN SARIO The Star 22 May 16;

KOTA KINABALU: Sabah’s endangered wildlife continue to be the target of poachers as recent raids by authorities here over the past week have shown.

Sabah Wildlife Department rangers stumbled on three carcasses of bearded pigs and a mousedeer when they stopped a four wheel drive pick up truck along the Paitan-Kanibongan road in northern Sabah on Saturday.

Department director William Baya said the three people who were inside the vehicle had been detained for further investigations under Section 41 (2) of Wildlife Conservation Enactment 1997 for illegal possession of protected wildlife.

He said more wildlife species were seized in a joint enforcement operation by the department, Forestry Department and police in Tawau between May 20 and 22.

Baya said three groups of individuals were detained after they were found to be in possession of the carcasses of a civet cat, a flying fox and bearded pigs.

Stressing that the department was continuing its crackdown against poachers, he said hunters should apply for the necessary permits first.

Bearded pig, mousedeer carcasses found during roadblock
OLIVIA MIWIL New Straits Times 22 May 16;

BELURAN: A roadblock along the Paitan-Kanibongan road here yesterday morning turned up unusual discoveries in the form of exotic animal carcasses.

Three people were arrested by the Sabah Wildlife enforcement team when the carcasses of three bearded pigs and a mousedeer were found in their 4WD vehicle.

The trio will be investigated under Section 41(2) of the Wildlife Conservation Enactment 1997 for possession of protected wildlife product without permit. Elsewhere, three other groups of people were arrested for similar offences between May 20 and 22 in Tawau.

The joint operations between the Wildlife, Forestry Department, police and Sabah Foundation yielded wildlife species such as bearded pigs, civet cats and flying foxes.

State Wildlife director William Baya, in a statement today, reminded the public to obtain permits when engaging in protected wildlife related activities to avoid enforcement action. Between Jan 2014 and Sept 2015, more than 20 people were charged with possession of wildlife.

Indonesia: Hunting of endemic pig-deer continues in Sulawesi

Syamsul Huda M. Suhari The Jakarta Post 22 May 16;

Rife hunting of the babirusa pig-deer in Gorontalo continues with hunters seeking the animal for its meat amid accusations that the pig-deer is destructive of local plantations. There are four species of pig-deer endemic to Indonesia, the North Sulawesi pig-deer — the most well-known — is virtually hairless, unlike the those found outside of Sulawesi. Buang Hassan, head of Lembah Permai subdistrict in Wongarasi district, Pohuwato regency, said the forest in his region had been used as a gateway for pig-deer hunters looking to hunt the animals.

He said that at least four hunters visit the region each week to hunt, both individually and in groups.

“They don’t just hunt pig-deer, they also kill wild boar and sometimes anoa,” Buang told The Jakarta Post recently.

Buang claims that most hunters come from neighboring subdistricts such as Banuroja and Londoun and usually stay in the forest for three to four days to hunt.

He said that they hunted using mesh, locally known as dudeso, and used small rafts to transport their catch along the river. A raft reportedly enables the hunters to transport between two to four boars home each trip.

To deceive security personnel, hunters, according to Buang, tend to chop the animals into pieces before leaving the forest, selling the meat as far away as North Sulawesi.

Buang said the Lembah Permai subdistrict administration had been unable to do anything to stop the illegal hunting of the pig-deer. “The hunting ground is far from here, this subdistrict is only an entrance gate. And they hunt to support their respective families,” he said.

Lembah Permai is a transmigration area, inhabited since 1993. The population comprises various ethnic groups, including Minahasa and Bolaang Mongondow. Apart from being traded as meat, the North Sulawesi pig-deer is often netted in traps set by local farmers to protect their plantations.

The head of the Second Conservation Region of Gorontalo’s Natural Resources Conservation Agency ( BKSDA ), Syamsuddin Hadju, said such practices were common among farmers living around the Nantu Forest Wildlife Reserve in the Gorontalo and Boalemo regencies.

“As their plantation areas are close to Nantu forest, pig-deer wander into the traps while looking for food,” said Syamsuddin, adding that locals were also known to deliberately set traps inside the conservation forest.

He said routine surveillance was conducted in the area in cooperation with the local police. Meanwhile, a campaign for the preservation of the local pig-deer population — estimated to have declined to a total of 5,000 — has also intensified.

Nantu is considered important because it is the only forest in Sulawesi where people are able to observe the pig-deer at close range. Each morning and afternoon, a herd of pig-deer visit the Adudu mudhole in search of water.

Lynn Marion Clayton, founder of Yayasan Adudu Nantu Internasional ( YANI ), refers to the mudhole as the pig-deer herd’s health cafe.

With a PhD in Conservation Biology from Oxford University, Clayton, who has been conducting research on hog deer in Nantu forest since the 1990s, explained that the ground water in the mudhole had a high salt and mineral content and thus, the water is an antidote for a toxin contained in Pangi or kluwak, one of the pig-deer herd’s favorite foods.

UAE: $5.8m grant launched for saving endangered dugong and seagrass ecosystems

Mohammad Bin Zayed Species Conservation Fund announces launch of grant during Global Communication Conference
Sami Zaatari Gulf News 22 May 16;

Abu Dhabi: The Mohammad Bin Zayed Species Conservation Fund (MBZ Fund) on Sunday announced the launch of a $5.8 million (Dh21.30 million) grant to save the endangered dugong and its seagrass ecosystems across the Indian Ocean and the South Pacific.

The announcement of the grant was made at the Global Communication Conference, and coincided with International Day for Biological Diversity. As part of its initiative, the MBZ Fund also announced that it would be partnering with students from Zayed University and 16 other international universities to help raise awareness on the subject.

“The presence of dugong and seagrass in a marine ecosystem is a good indication that the ecosystem is healthy. Protecting these species and their environment is good for local communities because a healthy marine environment provides plentiful food, protects coasts from storm erosion and ensures clean seawater,” Razan Khalifa Al Mubarak, managing director of the MBZ Fund, said.

“The Dugong and Seagrass Conservation Project, executed by the MBZ Fund, represents an unprecedented global investment in the conservation of these endangered species and contributes to Abu Dhabi’s already impressive track record of supporting environmental conservation efforts worldwide.

“Working with Zayed University students and their counterparts from different universities across the world gives the Fund the opportunity to tap into the insights of a digitally connected and environmentally aware generation,” she added.

Dr Frédéric Launay, board member and acting director-general at the MBZ Fund, speaking on the issue of creating awareness, said it was not easy and that it would take hard work to get the message across and people invested in the matter.

“This is a challenge — how to convey the needs to care and feel responsible for the fate of species and its ecosystem, in eight countries of the Indian and Pacific Oceans, with a wide array of culture, tradition, and language.

“It is a challenge to convince people to work together to save species that most people will never actually see in its environment. Saving species is a challenge that the MBZ Fund took eight years ago, at a time where species conservation and the people committed to it, were left alone. Today the Fund has supported more than 1300 projects in over 140 countries,” he added.

Malaysia: Johor to supply water to Singapore despite shortage

The Star 22 May 16;

KOTA TINGGI: Johor has assured Singapore that it will continue to supply water to the republic despite the state facing a water shortage.

State Public Works, Rural and Regional Development committee chairman Datuk Hasni Mohammad said Johor would respect the agreement signed between Malaysia and the island republic in 1962.

"Under the agreement, we have to supply 250 million gallons of water at three cents per litre to Singapore daily.

"Even though the selling price does not make sense given the current environment, it is stipulated under the agreement," he said at Kejora's entrepreneurship carnival and human capita expo at Bandar Penawar here yesterday.

He said the agreement would last 100 years until 2061.

Hasni said several quarters had urged the state government to stop supplying water to Singapore due to the current water shortage.

"The first 50 years of the agreement had already ended with Singapore handing over the Pontian and Gunung Pulai reservoirs back to us in 2011," he said.

He said Johor would need help from the Federal Government in ensuring the state had enough water beyond 2018.

"We must meet the demand for water for development and the investment being poured into the area, especially for Johor Baru and Pasir Gudang.

"We have asked for an allocation of RM660mil under the 11th Malaysia Plan to build a new dam at Sungai Ulu Sedili," he said.


Johor to continue supplying water to Singapore despite shortage: Report
State Public Works, Rural and Regional Development committee chairman Hasni Mohammad said that Johor will respect a 1962 agreement for the state to supply water to Singapore, The Star reported.
Channel NewsAsia 22 May 16;

SINGAPORE: Despite a shortage, Johor will honour a 1962 agreement signed between Singapore and Malaysia to supply water to Singapore, The Star reported on Sunday (May 22) citing State Public Works, Rural and Regional Development committee chairman Hasni Mohammad.

Under the 99-year agreement which lasts until 2061, Singapore has full and exclusive right to draw up to 250 million gallons of water daily from the Johor River at the price of 3 sen per 1,000 gallons. The river supplies about half of Singapore's water needs.

Mr Hasni was quoted by The Star as saying that “even though the selling price does not make sense given the current environment, it is stipulated under the agreement". The official’s comments came after “several quarters” urged the state government to stop supplying water to Singapore due to the current water shortage, reported The Star.

Water levels in Johor's Linggiu Reservoir fell to a historic low of 35 per cent last month. Mr Hasni also reportedly said that Johor would need help from Kuala Lumpur to ensure the state “had enough water beyond 2018”.

"We must meet the demand for water for development and the investment being poured into the area, especially for Johor Baru and Pasir Gudang,” he said, according to The Star.

As part of the 1962 Water Agreement, Johor buys treated water back from Singapore at 50 sen per 1,000 gallons, a fraction of the cost to Singapore of treating the water, which includes building and maintaining the water purification plants.

Last August, Singapore temporarily raised the amount of potable water supplied to Johor from the usual 16 million gallons to 22 million, as the Malaysian state grappled with a dry spell.

Pulau Ubin: New coastal boardwalk, otter dens for Ubin

KENNETH CHENG Today Online 22 May 16;

SINGAPORE — Work to restore the shoreline of Pulau Ubin - announced as part of the Ubin Project in 2014 - is set to begin next year, with completion slated for early 2020.

As part of shoreline restoration efforts, a coastal boardwalk, which will span about 500m in length and partly extend into the sea, will also be built. From the boardwalk, visitors will have views of the island's coastal mangroves and hills.

Providing an update on Sunday (May 22), the National Parks Board (NParks) said feasibility studies for shoreline restoration efforts on the island, which began in the middle of last year, wrapped up earlier this month.

Pulau Ubin's shoreline, particularly at Noordin Beach in the island's north, had been observed to be eroding, threatening coastal and mangrove habitats and exposing the foundations of old buildings, among other things.

Changes in wave conditions, due in part to ship wakes, as well as land-use change, NParks said, were found to be among the principal causes of the erosion.

Following modelling studies by external consultants, the possible measures identified to tackle the erosion include constructing headlands with armour rocks.

The headlands, to be spaced 200m apart and with sand nourishment between them, will serve as control points, enabling a crenulated-shaped beach to develop.

Noordin Beach, a popular camping site forced to shut in 2013 because of severe erosion, will reopen to the public for outdoor recreation when the restoration works are completed.

Also unveiled on Sunday was a design for new otter dens, or "holts", as part of species recovery efforts for the oriental small-clawed otter - the first time such spaces are being built for the critically endangered species endemic to Pulau Ubin and Pulau Tekong.

Two such otter holts will be erected at Noordin Beach and near the Sensory Trail ponds on the island by year-end to monitor and study the behaviour of the mammals.

Species recovery efforts are also underway for bats on the island, with a bat house established near Noordin Beach earlier in the year and 30 bat boxes being installed progressively across the island.

Senior Minister of State (Home Affairs and National Development) Desmond Lee, who joined the community in planting mangrove saplings on Sunday morning at the island's mangrove arboretum, said more must be done to protect the rich biodiversity on Pulau Ubin.

But the authorities cannot do this alone, he noted. "There will certainly be more avenues for community participation with initiatives such as the orchid conservation project and mangrove restoration programme.

"I hope that many more Singaporeans will join us in our endeavour to conserve the many living organisms that exist alongside us," he said.


Pulau Ubin to have coastal boardwalk after shoreline restored
There have also been efforts to protect critically endangered species unique to the island, like the Oriental Small-clawed Otter.
Alice Chia Channel NewsAsia 22 May 16;

SINGAPORE: Pulau Ubin will boast a new coastal boardwalk for the public once shoreline restoration works - set to begin in 2017 - are complete, said Senior Minister of State for National Development Desmond Lee on the island on Sunday (May 22).

About 100 members of the public gathered at Pulau Ubin on Sunday morning to plant mangrove saplings. When the mangroves mature, the public can get to view them from the boardwalk that will be built as part of efforts to restore the island's shoreline.

Said Mr Lee: "In the past year, NParks has worked hard to restore Ubin's shoreline. We started feasibility studies in mid-2015 and shoreline restoration work will commence soon. It will be a major project.

“At the same time, we will provide a coastal boardwalk which will extend into the sea in the north of Ubin, so that visitors can enjoy vistas of the sea and coastal forests.”

The shoreline on two beaches - Noordin and Mamam Beach - will be extended from 2017. In time to come, Noordin Beach will be reopened for outdoor recreational use, Mr Lee added.

There have also been efforts to protect critically endangered species unique to the island, like the Oriental Small-clawed Otter. New otter holds or dens have been designed to monitor and study their behaviour.

About 800 orchids of 15 different species are also being propagated and reintroduced across the island, as part of the NParks Orchid Conservation Programme.

More activities that showcase the biodiversity on Pulau Ubin's shores will be held on Ubin Day on Jun 4.

Plans to protect Pulau Ubin’s rich biodiversity in the works
KENNETH CHENG Today Online 23 May 16;

SINGAPORE — A rejuvenated shoreline, a new coastal boardwalk and spaces for critically endangered animal species — such as otter dens — are in the works for Pulau Ubin, in an effort to protect the island’s rich biodiversity.

Works to restore the island’s shoreline — in particular the northern shoreline — are expected to begin next year and conclude by early 2020, the National Parks Board (NParks) announced on Sunday (May 22). A tender will be called soon for this purpose.

Plans to restore the shoreline were announced in 2014 as part of the Ubin Project, an ongoing effort to gather suggestions on enhancing its natural environment and protecting its rustic charm. Pulau Ubin’s shoreline, particularly at Noordin Beach in the island’s north, had been observed to be eroding, threatening coastal and mangrove habitats and exposing the foundations of old buildings, among other things. Erosion was also behind the closure of Noordin Beach, a popular camping site, in 2013.

Feasibility studies on shoreline restoration work, which took place over a year and wrapped earlier this month, found that changes in wave conditions, due in part to wakes generated by the movement of ships, as well as land-use change, were among the key causes of the erosion.

Following modelling studies by external consultants, the construction of headlands with armour rocks has been identified as a possible measure to restore the island’s northern shoreline, particularly at the Noordin and Mamam beaches. The headlands, spaced 200m apart from one another and with sand nourishment between them, will serve as control points, allowing for a curved beach to form.

In addition, mangrove restoration measures will be deployed in tandem by filling undercuts chiselled by waves with substrate in biodegradable sacks — such as soil — alongside rocks at the toe, to shield the shoreline from further erosion by the waves. Wooden poles will also be erected to break up the energy of the waves, creating an environment conducive to the growth of mangroves.

These measures, NParks said, have been “assessed to be most suitable in protecting and rehabilitating the northern shoreline with minimal impact to the surrounding”.

A coastal boardwalk, which will span about 500m in length and partly extend into the sea, will also be built as part of shoreline restoration efforts. From the boardwalk, visitors will have views of the island’s coastal mangroves and hills. Noordin Beach will reopen to the public for outdoor recreation when the restoration works are completed.

Also unveiled on Sunday was a design for new otter dens, or “holts”, as part of species-recovery efforts for the oriental small-clawed otter.

It is the first time such spaces are being built for the critically endangered species endemic to Pulau Ubin and Pulau Tekong.

Two such otter holts will be erected at Noordin Beach and near the Sensory Trail ponds on the island by year-end to monitor and study the behaviour of the mammals. Species-recovery efforts are also underway for bats on the island, with two bat houses set up near Noordin Beach and at Bukit Belukar earlier this year and 30 bat boxes being installed progressively across the island.

Senior Minister of State (Home Affairs and National Development) Desmond Lee, who joined the community in planting mangrove saplings at the Ubin Living Lab’s mangrove arboretum on Sunday, said more must be done to protect Pulau Ubin’s rich biodiversity.

But the authorities cannot do this alone, he noted. “There will certainly be more avenues for community participation … I hope that many more Singaporeans will join us in our endeavour to conserve the many living organisms that exist alongside us,” he said.

Conservation expert Ho Hua Chew, vice-chair of the Nature Society (Singapore)’s conservation committee, said the shoreline restoration works were “necessary”.

Dr Ho pointed to the importance of breaking up wave action in preventing further erosion, and was confident that NParks had studied the shoreline and wave movements and considered its course of action carefully.

On the other hand, Mr Ben Lee, founder of nature conservation group Nature Trekker, thought the plan to erect a boardwalk unnecessary. A boardwalk will attract scores to the island’s north, disturbing the tranquility of the area, he said, adding that its development would also have an impact on the environment. “To me, Ubin is to be left as natural as possible — (that) is the best,” Mr Lee said.

Meanwhile, an upcoming community event to celebrate all things Ubin — Ubin Day on June 4 — will include guided walks and craft workshops showcasing the island’s biodiversity. Author Neil Humphreys will also be reading from his latest children’s book on Pulau Ubin, in a storytelling session for children below 12.

MORE will be done to protect Pulau Ubin's flora and fauna, including plans to restore its northern shoreline, build a coastal boardwalk and support the recovery of endangered plants and animals.

Announcing these initiatives yesterday at Pulau Ubin, Senior Minister of State for Home Affairs and National Development Desmond Lee said more must be done to protect the rich biodiversity teeming on the island.

Noting that it has more than 720 native plant species and over 500 animal species, including some not found on mainland Singapore, he added: "This is remarkable but we must do more.

"We have plans to restore Ubin's eroding shoreline, which will serve as a base for more of Pulau Ubin's flora and fauna to be restored in the near future."

Shoreline restoration was one of the earliest priorities for The Ubin Project, announced in 2014 to generate ideas from the public on how to retain the island's rustic charm.

Erosion has badly affected about 40m of northern Ubin, threatening critically endangered species like the Eye of the Crocodile tree and leading to the closure of Noordin Beach - a popular camping site - in 2013 for public safety.

A year-long study, which was concluded this month by the National Parks Board (NParks), found that changes in wave conditions partly as a result of ship wakes, or waves generated by the movements of vessels, as well as changes in land use were among the key causes of erosion.

NParks has identified possible measures to restore the shoreline, such as using man-made rock structures and sand to widen the existing beaches, growing more mangroves and adding wooden poles along the shoreline to mitigate the impact of waves.

NParks will call a tender and works are expected to start next year and end by 2020.

An impact assessment will be done, said NParks' director for Pulau Ubin, Robert Teo.

"Until we call a tender, we won't be sure how much (the work) is going to cost. It depends on the magnitude of the designs and the amount of work that's going to be done," he added.

A coastal boardwalk of about 500m, part of which will extend into the sea, will be built at Noordin Beach, which will reopen when restoration works are completed. From the boardwalk, visitors can view coastal mangroves and hills.

Yesterday, NParks also unveiled a design for new otter holts - which are dens for the critically endangered Oriental Small-clawed Otter. By the end of this year, two holts will be installed on the island which will allow researchers to monitor and study their behaviour.

Other species' recovery efforts include installing 30 bat boxes across the island for bats to roost, and reintroducing endangered native orchids to parts of the island.

At the event to mark the International Day for Biological Diversity, which was yesterday, Mr Lee joined more than a hundred participants to plant 100 saplings at the mangrove arboretum in the Ubin Living Lab.

Among them were executive manager Sean Lam, 47, and his wife and son.

He said: "This is one of the last places in built-up Singapore where you can enjoy such nature. Without the mangroves, the soil will be eroded and the next generation, they won't have anything to see."


Rare animals and plants in Pulau Ubin you won't get to see in Singapore
AsiaOne 23 May 16;

The next time you visit Pulau Ubin, take a closer peek at your surroundings, as it might reveal treasures of nature that are more unique and interesting than a cursory glance of the coastal and old kampong charms of the island.

You might have spotted wild boars foraging for food near bicycles parked by visitors, aquatic flowers blooming in ponds and big spiders trapping their victims in gossamer webs.

But do you know that the island off the Changi coast is is home to more than 720 native plant species and over 300 species of animals? What makes Pulau Ubin more special is that some of these species are found only on the island and not on mainland Singapore.

If you're thinking of taking a boat trip to the island again, do look out for these fascinating animals, insects and plants that have been clinging on for survival on the most endangered list. Bring along a pair of binoculars and marvel at close range.

Ashy Roundleaf Bat (Hipposideros cineraceus)
Two colonies of this critically endangered bats have been made abandoned buildings in Pulau Ubin their homes. Although found in South Asia and Southeast Asia, it has never been spotted on the mainland.

Lesser False Vampire (Megaderma spasma)
In Singapore, this bat (above) is found only on Pulau Ubin and Pulau Tekong. Recently, Ubin has become popular with this species as several colonies have been found occupying disused structures. It feeds primarily on insects. No, it does not go after your blood.

Oriental Small-clawed Otter (Aonyx cinerea)
Nine sightings of this otter (below) on Pulau Ubin have been recorded over the past 16 years. No recent sightings on the mainland.

Dwarf Crow (Euploea tulliolus ledereri)
Believed to be extinct in Singapore but rediscovered on Pulau Ubin in 2002, this butterfly (below, left) flutters quite lazily, usually drawn to the hairy Indian Heliotrope plant (Heliotropium indicum).

Common Jay (Graphium doson evemonides)
Last spotted on the mainland in 2006, it was found again on Pulau Ubin in 2005. The Common Jay (below, right) is constantly on the move, flitting from one flower to another to feed on nectar.

Greater mouse-deer (Tragulus napu)
Thought to be extinct on the mainland, there is a sizable population on Ubin. It inhabits forested areas, and emerges at night to forage for fallen fruits, leaves, grasses and aquatic plants.

Rare trees and orchids

Collared fig (Ficus crassiramea)
This critically endangered tree can be found in Pulau Tekong and Pulau Ubin only. There are a few specimens of this 'killer' tree on Ubin, including one acknowledged officially as a Heritage Tree near Ketam Mountain Bike Park. The 'strangling fig' grows from a seed left by animals like birds at the top of a tree. From here, it fans out its roots downwards till it encircles the host tree's trunk. In many cases, the host tree is finally "strangled" to death after many years.

Eye of the Crocodile (Bruguiera hainesii)
Critically endangered, it is one of the rarest mangrove species in the world with only about 200 mature trees left. Eleven including two on Ubin are found in Singapore. One tree was found in the southern coast of Ubin, while another was discovered on Noordin Beach in 2005. National Parks (NParks) has started a programme to collect and plant young seedlings to increase the population.

Ficus stricta
Another rare species of the strangling fig, it was listed as native to Singapore only in 2012, after the first specimen was discovered in Changi. It is only known to thrive in Changi and Pulau Ubin. In the 19th century, British engineer and artist John Turnbull Thomson produced a drawing of a tree in 1850, which is thought to be the same one found near the mouth of Sungei Pulau Ubin, in 2002. Listed as a Heritage Tree, it is believed to be more than 160 years old. It bears fruit only after intervals of more than six years. Oriental Pied Hornbills and Green Imperial Pigeons have been spotted feeding on the figs.

Hybrid stilt mangrove-happy face (Rhizophora X lamarckii)
In 2011, an NParks staff chanced upon this naturally-occurring mangrove hybrid of of the Rhizophora apiculata and Rhizophora stylosa, creating a new record here. So far, five trees have been found at the Sungei Jelutong and Jalan Noordin mangrove.

Marsh Pulai (Alstonia pnuematophora)
It stands out from other Pulai trees because of its 'breathing' roots. Found mainly in the central forests on the mainland, a few trees flourish on Pulau Ubin.

Jamba (Neuwiedia veratrifolia)
Found in lowland forests, this critically endangered orchid (above) produces long clusters of yellow flowers. Grown on soil, the Jamba will see its population multiply as plantlets at one site have been transplanted to two other areas on Ubin.

Pterospermum diversifolium
This tree species was first collected by Henry Ridley, former director of the Singapore Botanic Gardens. It was thought to be extinct, but was found in Pulau Ubin in 2013. Currently, fewer than 50 mature trees are seen in Singapore.

Sheath-covered Spathe Robiquetia (Robiquetia spathulata)
This critically endangered orchid was recorded only once in Singapore by Henry Ridley, who collected it near the Botanic Gardens. It was only in 2006 that a single plant was rediscovered in Pulau Ubin. Through tissue culture, the species has been successfully propagated and reintroduced to other parts of Pulau Ubin, as well as mainland Singapore.

Thrixspermum amplexicaule
You would be lucky to catch a glimpse of this rare pale lilac orchid as its blooms last for only a day. The semi-aquatic orchid was found at one site on Ubin, but it has been successfully propagated and reintroduced to other sites on the island since 2010. Still regarded as critically endangered.

Utania nervosa
Discovered at Ubin's Chek Jawa in 1997, this small tree was named as a new species called Utania racemosa in 2014. A common tree on Pulau Ubin and Pulau Tekong, it is also found in south-east Johor. It has large, leathery leaves shading clusters of white flowers with very short stalks.


Community participates in efforts to enhance Pulau Ubin’s natural heritage as part of the International Day for Biological Diversity celebrations on island
NParks 22 May 16;
* New shoreline restoration measures to be carried out at Noordin Beach
* New coastal boardwalk for public to be built

Singapore, 22 May 2016 — Members of the community today gathered at Pulau Ubin to participate in reforestation and species recovery efforts as part of the International Day for Biological Diversity celebrations on the island. Senior Minister of State for Home Affairs and National Development, Desmond Lee, together with over 100 members of the community, planted mangrove saplings at the Ubin Living Lab’s new mangrove arboretum to help reforest the island’s mangroves. In addition, SMS Lee gave an update on the progress for some of species recovery efforts initiated by the Friends of Ubin Network (FUN) as part of The Ubin Project. SMS Lee also announced that the National Parks Board (NParks) will begin physical works for shoreline restoration at Noordin Beach in 2017. As part of restoration works, a new coastal boardwalk will be built for the public to appreciate views of the sea and coastal forests.

SMS Lee said, “Singapore may be small, but we are teeming with biodiversity. Just in Pulau Ubin alone, we have over 720 native plant species and over 500 animal species, including some not found on mainland Singapore. This is remarkable, but we must do more. We have plans to restore Ubin’s eroding shoreline, which will serve as a base for more of Pulau Ubin’s flora and fauna to be restored in the near future.

But we cannot do this alone. As we gather to mark the International Day for Biological Diversity on Pulau Ubin today, we also celebrate the strong partnership with the community that has allowed us to achieve progress in our species recovery efforts for the unique biodiversity on the island. There will certainly be more avenues for community participation with initiatives, such as the orchid conservation project and mangrove restoration programme. I hope that many more Singaporeans will join us in our endeavour to conserve the many living organisms that exist alongside us.”

International Day for Biological Diversity celebrations on Pulau Ubin

The International Day for Biological Diversity is held yearly worldwide on 22 May to increase global awareness of biodiversity issues. As part of the celebrations on Pulau Ubin, the public could attend talks and workshops about the island’s biodiversity. In addition, the community, including FUN members, planted 100 trees at the mangrove arboretum in the Ubin Living Lab. In the long run, these trees would supplement restoration efforts across the island. Mangrove forests are vital to the coastal zone in Pulau Ubin as they protect the shoreline from erosion. Restoring mangrove ecosystems would in turn conserve the habitats for native biodiversity like fiddler crabs and mudskippers. The activities organised today were part of NParks’ efforts to raise awareness and deepen public appreciation for native biodiversity on the island, as well as share how the public can play a part to sustain our natural heritage for future generations.

Shoreline restoration works at Noordin Beach – new boardwalk to be built for public

Shoreline restoration was one of the earliest priorities for The Ubin Project when it was first announced in 2014. The island’s shoreline was observed to be eroding, in particular the northern part of the island at Noordin Beach, along the mangroves and low cliff faces. This has led to a loss of coastal and mangrove habitats. Furthermore, the erosion exposed the foundations of old buildings and undermined the structural integrity of two shelters. The severity of the erosion led to the closure of Noordin Beach, a popular camping site, in 2013 for public safety.

Feasibility studies for shoreline restoration efforts began in mid-2015 and concluded in May 2016. Some of the key causes of erosion were identified to be changes in wave conditions partly due to ship wakes as well as changes in land use.

Consultants have carried out modelling studies to assess various measures. The use of headlands as well as the addition of sand to extend the shoreline seaward has been identified as a possible measure to restore the island’s northern shoreline in areas including Noordin Beach and Mamam Beach. This will be supplemented by mangrove restoration efforts. The headlands will also provide opportunities to restore beach vegetation in the area.

When works are completed, Noordin Beach will be reopened for visitors to engage in nature-based recreation. In addition, a coastal boardwalk of about 500 m long would be integrated into the restoration works, part of which will extend into the sea, affording visitors views of the island’s coastal mangroves and hills. Furthermore, restoration of Pulau Ubin’s shoreline will lay the foundations for future phases of habitat enhancement and species recovery projects. See Factsheet A for more details on shoreline restoration measures.

Species recovery efforts under The Ubin Project – design for otter holts unveiled

NParks unveiled a design for new otter holts or dens to be used in species recovery efforts for the Oriental Small-clawed Otter (Aonyx cinerea). As part of overall species recovery plans mapped out under The Ubin Project, these holts are being constructed for the critically endangered native otter for the first time in Singapore. By end-2016, two holts will be installed at Noordin Beach and near the Sensory Trail ponds to monitor and study otter behaviour.

Much of Pulau Ubin’s rustic charm lies in the unique native biodiversity which cannot be found on the mainland. The native Sheath-Covered Spathe Robiquetia (Robiquetia spathulata) orchid was previously thought to be extirpated until it was rediscovered in 2006 by NParks staff. Together with other endangered native orchids like the Jamba (Neuwiedia veratrifolia) and Thrixspermum amplexicaule, these are among some 800 orchids from 15 distinct species that are currently being propagated and reintroduced across Pulau Ubin as part of the NParks Orchid Conservation Programme.

Other species recovery efforts include installing 30 bat boxes of six different designs across Pulau Ubin for insectivorous bats to roost. One of these boxes has been installed at the Ubin Living Lab. The bat recovery programme aims to increase the diversity of bats on Pulau Ubin, and assist in the recovery of uncommon species. Part of this programme will complement the forthcoming shoreline restoration works as a bat house has been set up near Noordin Beach in early 2016.

Examples of biodiversity found on Pulau Ubin and not on mainland Singapore are in Factsheet B.

Restoring Ubin Mangroves (RUM)

Amongst those who planted at the mangrove arboretum today were RUM members. Conceived during one of the FUN sessions, the RUM initiative serves to restore mangrove forests through a science-based approach complemented by community outreach efforts. The Ecological Mangrove Restoration (EMR) approach will be applied based on science-informed methods, taking into consideration site characteristics and environmental factors to regenerate mangrove populations. Mangrove restoration measures are being considered for the mangroves along Sungei Besar, Sungei Mamam and Sungei Jelutong. Some of these mangrove restoration efforts may also be adapted to protect the island’s shorelines where they have been observed to be eroding. More details of the EMR can be found in Factsheet C.

RUM Members include the Marine Conservation Group of the Nature Society (Singapore), Gamefish and Aquatic Restoration Society (GARS), Eastern fish farmers at Pulau Ubin, the Mangrove Lab (Department of Geography, National University of Singapore) and founder of wildSingapore, Ms Ria Tan. This is coordinated as part of NParks' habitat restoration and reforestation programme on the island.

Public activities on Pulau Ubin

Members of the public who wish to learn more about Pulau Ubin’s cultural and natural legacy may sign up for activities under Pesta Ubin, organised by volunteers and FUN members, running from 14 May to 12 June. Details can be found on the Pesta Ubin website at http://pestaubin2016.blogspot.sg/.

The upcoming Ubin Day on 4 June offers more opportunities to participate in events centred on Pulau Ubin’s heritage. Activities include guided walks and craft workshops which showcase the biodiversity on Pulau Ubin’s shores. Children below the age of 12 can also join in a storytelling by bestselling author Neil Humphreys, who will be sharing from his latest children’s book on Pulau Ubin. Please visit www.nparks.gov.sg/ubin for more information and to register for activities.

MEDIA FACTSHEET A
Shoreline Restoration Works at Noordin Beach

Pulau Ubin’s shoreline was observed to be eroding, in particular at the northern part of the island at Noordin Beach, along the mangroves and low cliff faces. This has led to a loss of coastal and mangrove habitats. The southern coastline was observed to be generally stable with the exception of a few areas.

Feasibility studies for shoreline restoration efforts began in mid-2015 and concluded in May 2016. These were the steps taken to determine the causes and explore possible mitigating measures to arrest the erosion.

1. Data Collection and Site Assessment: Existing information such as satellite images, hydrodynamics, ecological and land use data was reviewed. A series of topographical, hydrographical, mangroves, sediment and vessel traffic surveys was also conducted. These allowed us to understand the existing conditions at Pulau Ubin and determine the extent of erosion and impact on ecological habitats along the entire shoreline of the island.

2. Coastal Dynamic Assessment and Identification of Erosion: Hydrodynamic and wave modelling was conducted to assess causes and effects of erosion around the island. Based on the modelling results, critically eroded areas of importance were identified for protection/restoration. This included Noordin Beach in the north of the island.

3. Identification and Evaluation of Mitigating and Restoration Measures: Based on the identified causes of erosion and affected areas, potential restoration and mitigation measures were developed and tested via modelling to assess their effectiveness.

4. Shoreline Stabilisation Plan: Measures that have been developed will be consolidated in a holistic plan for the monitoring and management of the coastline in the long term. This plan encompasses monitoring and management measures for target areas and the rest of the coastline.

Some of the possible causes of erosion which were identified include:
• Changes in land use – Aquaculture ponds which are no longer in use have led to breaches in the surrounding bunds over time. The disuse of the ponds’ tidal gates has also resulted in uncontrolled inflow and outflow of water from the ponds. This has increased the volume of water leaving the ponds at ebb tide, causing erosion at the river mouths and mangrove habitats at Sungei Besar and Sungei Mamam.

• Impacts from waves and ship wakes – The average environmental wave condition at Pulau Ubin is mild. However, wakes generated by vessel movements at certain sections of the shoreline with high vessel traffic cause higher wave energy, removing sediment away from the foreshore, resulting in the shoreline retreating. Wave energy is greatest in the east (Chek Jawa Wetlands), with its force decreasing westward along the shoreline. Vessel wake energy appears to be most prevalent in the narrow strait between Pulau Ubin and Johor, especially at the northwestern end of the island.

Consultants have carried out modelling studies to assess which measures are likely to be effective. Based on the identified causes of erosion, possible measures which were considered to restore the island’s northern shoreline include man-made hard structures such as groynes, detached breakwaters or headlands as well as the addition of sand to widen the existing beach.

• Headlands coupled with Beach Nourishment
The headlands will be constructed with armour rocks and spaced 200 m apart with nourishing of sand at the shoreline in between. With the headlands acting as control points, a crenulated-shaped beach can thus be formed, creating a more advanced shoreline than the current position.

Based on model testing of the different hard engineering measures, this, coupled with mangrove protection measures, has been assessed to be most suitable in protecting and rehabilitating the northern shoreline with minimal impacts to the surrounding.

• Mangrove Restoration Measures
Mangrove restoration measures which consist of mangrove toe protection and rehabilitation were also considered for the eroded mangrove shorelines at Sungei Besar, Sungei Mamam and Sungei Jelutong to stabilise the shoreline and prevent further loss of mangrove habitats.

The placement of suitable substrate to fill the mangrove undercuts, as well as rocks along the toe, helps to protect the shoreline from further wave actions. The wooden poles form a semi-permeable wave barrier to attenuate the wave actions and
encourage sediment accumulation in front of the toe protection, creating a conducive environment for mangrove growth. Such mangrove restoration measures have been tested in Sungei Buloh Wetland Reserve and were found to be effective.

Filling in disused aquaculture ponds will help control the inflow and outflow of water through the tidal gates, thus regulating the volume of water exchanged during tidal cycles and reducing wave impact. This allows for more sediment accumulation,
which encourages mangrove growth. The new mangroves will in turn arrest erosion to prevent further loss of mangrove habitats.


Part of the works to restore Pulau Ubin’s northern shoreline will also incorporate a coastal boardwalk approximately 500 m long, part of which extends into the sea. This would allow visitors to view the island’s coastal mangroves and hills.



MEDIA FACTSHEET C

Ecological Mangrove Restoration (EMR)

Ecological mangrove restoration (EMR) is defined as “an approach to coastal wetland rehabilitation or restoration that seeks to facilitate natural regeneration in order to produce self-sustaining wetland ecosystems.”

This approach works with physical processes, especially elevation and hydrology, to improve restoration success by ensuring that the site conditions are right for the mangrove species selected. Some ways in which this can be achieved include increasing the elevation of the site and widening channels to improve hydrology, thus easing the flow of propagules from elsewhere. In allowing mangrove propagules to disperse within an area naturally, it reduces the need to manually plant propagules. This may result in a more sustainable EMR project in the long run as a steady supply of propagules from beyond the site replaces seedlings which
may be lost by waves or infestation.

The factors which will guide the selection of mangrove species for the EMR process are:
• Species-specific traits such as tolerance to flooding
• Site characteristics including elevation, height of tides etc.
• Availability of propagules in the vicinity to disperse to the target site
• Tidal flooding, which increases the landward reach of waves and currents
• Wave and current patterns
• Size of area

The steps for a successful EMR, as described by mangrove researcher, R.R. Lewis, are:
1. Understanding the species ecology (reproduction, dispersal, seedling establishment)
2. Understanding hydrological patterns determining seedling distribution and establishment
3. Assessing man-made modifications to the environment that may be preventing natural colonisation
4. Selecting the most appropriate restoration site possible, using information from Steps 1–3. Besides assessing physical and ecological parameters as above, this step also involves anticipating and resolving community issues such as land tenure and land
use, to allow long-term access to the site and the sustainability of conservation.
5. Designing the restoration site to restore appropriate hydrology and natural recruitment
6. Only actively plant propagules and seedlings if step 4 will not be successful or rapid vegetation cover is required

The EMR method has been widely adopted in many countries. Successful case studies include a community-based EMR in Tanakeke island in South Sulawesi, Indonesia. The reestablishment of the natural mangrove ecosystem yielded benefits to the local fishing
community such as greater storm protection and availability of non-timber forest products for local markets as well as subsistence use.

80-90% of animals 'released' on Vesak Day die within a day

Linette Heng, The New Paper AsiaOne 22 May 16;

The group approached the reservoir with fanfare, carrying drums and pails of fish.

They were performing a tradition called fang sheng (releasing life), a gesture of compassion and repentance for sin during Vesak Day - but the practice is illegal.

Mr Ben Lee, 52, founder of outdoor exploration group Nature Trekker, recounts the incident two years ago at Lower Peirce Reservoir.

Mr Lee tells The New Paper: "I was alone and there were about 20 of them in the group. They wouldn't listen to my requests to stop.

"They had about 200 fish of different species with them and all the fish were released."

He was horrified as he knew the act could endanger the ecosystem.

Mr Lee and the Nature Trekker group have been patrolling parks and reservoirs for the last few years, especially around the Vesak Day period.

That is when instances of releasing animals tend to go up.

Though they have no enforcement powers, Mr Lee says they just want to do their part to educate people that the practice can do harm.

"We will come armed with cameras and tell them firmly that releasing these animals would upset the ecological balance of the habitat."

The group has been doing these patrols since 2007.

Mr Lee says the releases "are on a decline but still a concern."

The Government launched the annual Operation No Release in 2004 to spread awareness of the dangers of releasing animals into parks, nature reserves and reservoirs.

Over the last two weekends, the National Parks Board and the Public Utilities Board have been patrolling too.

OVERWHELM

According to a previous NParks advisory, about 80 to 90 per cent of released animals will die within a day.

And if they survive, they could overwhelm the local animals.

National University of Singapore (NUS) ichthyologist Tan Heok Hui, who studies the ecology of non-native fish species in Singapore, says there are currently 92 non-native freshwater species recorded in reservoirs, canals and other water bodies.

Dr Tan has recorded 54 non-native fish species in Singapore's reservoirs. In the 1960s, there were only nine.

Out of the 54 species, 43 may have been introduced into the reservoirs via the release or discarding of unwanted aquarium fish.

The non-native species include the peacock bass and the giant snakehead. They are known to be invasive predators.

Dr Tan warned that these non-native fish could introduce diseases and exert a high degree of competition for resources.

"They could either wipe out the native species, or be eaten by native predators," he adds.

NUS researcher David Tan, 26, works at the Evolutionary Biology Laboratory and studies bird carcasses here.

He says released birds have a very poor chance of survival: "Most of these birds are captive creatures who have lost their instinct for survival.

NOT COMPASSIONATE

"There are also a variety of predators such as eagles, owls, squirrels and even scavengers like crows, that will prey on them."

The scaly-breasted munia and Java sparrow are birds often released as part of fang sheng as they are common in the pet bird trade.

These birds are not native to Singapore, and their capture and trade fuels the decline of bird population in the wild, Mr Tan explains.

"It is actually not compassionate to release a captive bird because it is much more likely to have a shorter lifespan in the wild," Mr Tan says.

Malaysia: Water rationing in Johor continues

ROYCE TAN The Star 22 May 16;

SERDANG: Water woes have not ended yet in Johor despite the water levels at several dams in the country showing improvement over the past week due to the heavy rains.

National Water Services Commission (SPAN) CEO Datuk Mohd Ridhuan Ismail said the Bukit Merah dam in Perak especially, has shown significant improvement.

He said the water level was at 8.10m or 74.8% capacity.

According to Mohd Ridhuan, Johor still faces water rationing.

"The levels at the water treatment plants in Johor are increasing but still below critical levels.

“We will have to continue with water rationing in Mersing and Kota Tinggi until June 15," he told reporters after flagging off some 1,500 participants for the Thirsty Runner 2016 at the Malaysia Agro Exposition Park Serdang (MAEPS) here Sunday morning.
