Butterfly watching – also called butterflying – involves the observation and study of butterflies. With the main aim of popularising interest among the public, the Butterfly Conservation Society of Sri Lanka (BCSSL) will be launching the photographic guide ‘Field Guide to Butterflies of Sri Lanka’ that has more than 600 photos and illustrations of all of the 247 butterflies of Sri Lanka including the 26 endemics.

The guide is authored by a trio of young butterfly enthusiasts Himesh Jayasinghe, Sarath Sanjeewa Rajapakse and Chamitha de Alwis. Writing the foreword, butterfly expert Dr. Michael van der Poorten says he is impressed with the authors’ scientific field skills.

He introduces the young trio as butterfly researchers who understand the importance of careful observation, recording accurate field notes and making the proper identification. The guide is also a compilation of 15 years of field research by authors.

Through the photographs, the authors help even an amateur to distinguish butterflies from many different angles. The photos also show behaviour and living habitat of each species in most instances. “Some butterflies feed on fruits, some others on odd foods like bird droppings. Some butterflies perch at the bottom of leaves – We carefully handpicked the best photos that helps anybody to identify butterflies,” said Jayasinghe.

In 2013 the authors together with other butterfly enthusiasts formed the Butterfly Conservation Society, the first such organization in Sri Lanka aimed at studying butterflies and moths. They used different media to reach out to butterfly enthusiasts in the country and conducted several field studies on butterflies with previously unknown information about butterflies, their distribution, their larvae, host plants and feeding. The second edition of the pocket guide will be richer in content and not be a reprint of the first edition published in 2013 say the authors.

The publisher– the Butterfly Conservation Society is still a young organisation but its membership is growing steadily. Most importantly, the members are very active in the field. They meet every last Saturday of the month at the University of Colombo to share their knowledge and listen to a lecture on butterflies. Field visits are organised regularly. The only qualification to join the society is an interest in butterflies!

The Pocket Guide to the Butterflies of Sri Lanka – second edition will be launched on Saturday, December 19 at 4 p.m. at the Meteorological Department Auditorium, Bauddhaloka Mawatha, Colombo 7.

The guide will be available at a special price of Rs.1500 at the launch. The Butterfly Conservation Society can be reached on 0718181225 or butterflycssl@gmail.com for queries on the book and membership.

Wreckers of underwater treasures must be stopped

Fish are being dynamited as they shelter in the historically important shipwrecks scattered around Sri Lanka’s coastline, damaging valuable eco-systems and putting tourist earnings at risk.

Blast fishing is one of the most destructive fishing practices, used to stun or kill schools of fish for easy collection. The explosion destroys underlying habitat such as coral reefs that supports fish as well as other marine life.

Fishermen detonated explosives in the wreck Orestes, also known as Tango Wreck, which lies off Hikkaduwa, according to divers posting on the SubAqua Club forum.

A few months ago, another incident was reported by diver and marine expert Nishan Perera who took photographs of many dead big and small fish floating near the British Sergeant wreck off Passikudah after a dynamite fishing explosion. The wreck suffered some damage and nearby coral had been broken.

“On that day we reached British Sergeant around 9am and there was some fish floating on the surface, gasping for air,” said Thusitha Ranasinghe, an amateur diver who witnessed the destruction.

“We immediately knew that the ship wreck has been dynamited a few minutes ago and that the fishermen had left when they saw us coming.

“When we dived there were a lot of dead fish on the seabed and trapped on the deck of the sunken ship, and a lot of half alive fish trying to keep their buoyancy and gasp for a last bit of air,” he added.

There could be more than 200 shipwrecks around the coast, about 50 of which can be reached by diving, according to the comprehensive Dive Sri Lanka website.

Five hundred years of trade, commerce, conflict and war from the time of the Portuguese, Dutch and the British resulted in a vast amount of shipping traffic all round the coast and a corresponding high number of wrecks, Dive Sri Lanka states.

Most of these wrecks have been located, including world’s first purpose-built aircraft carrier, HMS Hermes, which was sunk off Batticaloa.

Shipwrecks creating special underwater attraction providing shelter for marine life becoming potential to be steady magnets for dive tourism that is still in at fancy level.

There is also the danger that fishermen dynamiting a wreck might do so carelessly while there were divers underwater. The Editor of Dive Sri Lanka, Dharshana Jayawardena, recalled one such incident, “It was scary.

It sounded like a tank exploding underwater, and the foreign tourists who were underwater with us were really scared. Fortunately, the dynamiting happened about 1km away, but the tourists with me swore they would not come again to Sri Lanka,” Mr. Jayawardena said.

“The dive industry in Sri Lanka is poised to grow hugely so this will have some real impacts on our international standing and ability to compete in the international dive market quite apart from the terrible environmental consequences” said Naren Gunasekera, who is lobbying to stop blast fishing.

Statistics show there are 23.7 million certified scuba divers in the world with 2.7m going on diving holidays. They are reportedly big spenders so this niche tourist segment would be economically beneficial but if we destroy our corals and shipwrecks there wouldn’t be anything to attract the tourists, Mr. Gunasekera points out.

A sunken ship turns to an artificial coral reef, providing living and breeding habitat for enormous amounts of marine life. Dynamiting these shipwrecks for their fish and the metal is like killing the goose that lays the golden eggs.

Dynamite is not only used on coral reefs and shipwrecks, it is being thrown into nets where large schools of fish are caught in order to prevent the fish tearing the net. Marine mammals such as dolphins and even the endangered dugongs are reported to be killed by dynamiting.

Sadly, because the destruction happens underwater, only divers can see the damage. It is important that the authorities understand the issue and take action to stop it, marine activists say.

It is, however, very difficult to carry out raids at sea to nab blast fishing culprits as they are highly organised, using mobile phones to convey alerts of approaching navy or police boats and dumping the evidence.

The fish die mostly of the shock wave, hence there is no physical damage that helps to prove they have been killed by blast fishing.

“Action to stop blast fishing needs to be taken on land, not at sea,” says Arjan Rajasuriya who was formally at National Aquatic Resources Research and Development Agency (NARA).

“Find out how these fishermen get dynamite and take action to stop it at source.”

As blast fishing is widespread, happening daily in many parts of Sri Lanka, Mr. Rajasuriya points out that those who illegally acquire a huge amount of dynamite should in any case be considered a threat to national security.

“In the same way that police and security forces nabbed the terrorists during the time of war, a good intelligence network is needed to find the source of the dynamite supplies and then stop them getting them into the hands of fishermen,” he said.

President Maithripala Sirisena launched an ambitious campaign to fight global warming, following last month’s global agreement reached to reduce emissions.

Named ‘Sri Lanka Next: Blue-Green Era’, the ceremonial launch took place at the BMICH on January 6 with schoolchildren and invitees in attendance. At the event, President Sirisena and those present read out a pledge to do whatever is necessary in the fight against global warming, and maintain the temperature increase under 2 degrees centigrade.

The pledge further says Sri Lanka will also endeavour to keep it under 1.5 degrees centigrade. The ‘Sri Lanka Next’ campaign will propel the nation into the next level of sustainable low emission development paradigm, where opportunities arising from the emerging new green and blue economy would be tapped.

Scientists predict human induced global warming triggered by excess greenhouse gases such as carbon dioxide will make the world hotter by several degrees if nothing is done.

The temperature rise is already being experienced through many extreme weather events triggered by it. Hence, the Paris climate talks ended with both industrialised and developing countries agreeing to cut emissions.

Sri Lanka’s greenhouse gas emissions are considered negligible, compared with industrialised countries, yet, ‘Sri Lanka Next’ promises a low carbon path for Sri Lanka to ease global warming.

Hence, our main focus would be towards adaptation, to confront the bad impacts of climate change.

The key focus of this national initiative is to ensure that Sri Lanka as a nation shift towards clean renewable energy and divests itself of fossil fuel consumption in the industrial and transport sectors.

President Sirisena at the event

The President recently re-introduced tax exemptions for electric cars, in trying to gain this goal.

But Sri Lanka is to set up another coal power plant in Trincomalee under Indian pressure, which will hurt this ambitious campaign warn energy experts.

A series of weeklong events, post launch of ‘Sri Lanka Next’, have been organised for Environment week which falls in the first week of June.

It will consist of a conference, exhibition and symposium on the Blue-Green Economy, followed by a film festival and a student-led event.

President Sirisena, who is also the Minister of Mahaweli Development and Environment, vowed to personally steer the campaign in conjunction with the Central Environmental Authority (CEA), the Forest Department’s REDD+ initiative, together with Department of Wildlife Conservation, the National Climate Secretariat (NCS) and all other relevant Government institutions, the Private Sector and international agencies.

However, the most important aspect is not just promises but the need to implement them, remind environmentalists.

Toxic frog joins elite endemic club

The Mihintale narrow-mouthed frog and below, the tadpole of this frog

The Mihintale narrow-mouthed frog and below, the tadpole of this frog

Mihintale is recognised as one of the world’s oldest wildlife sanctuaries, so it is fitting that a new frog found to be endemic to Sri Lanka has been named after Mihintale to honour its ancient values.

“On top of being a historic sanctuary, Mihintale is also the point of unison for two ancient cultures, when Mahinda Thera (Son of Indian Emperor, Asoka) met Dewanampiya Tissa (the king of Anuradhapura, Sri Lanka) in 246 BC. Hence we named the frog Microhyla mihintalei”, Dr. Madhava Meegaskumbura, who led the research team, said.

This frog is now officially called the Mihintale narrow-mouthed frog (Microhyla mihintalei). The specie is found mainly in the lowland dry zone and also has a small presence in some parts of the Wet Zone. The specimens these scientists used for their study lived near Mihintale.

As its name implies, the frog has a narrow mouth that restricts its diet to smaller prey such as termites and other ants. It is reddish in colour and a little bigger than Microhyla ornata (ornate narrow-mouthed frog) the other species in Sri Lanka that can be confused with this species. The females are bigger – up to 2 inches, while males can be 1.5 inches.

Being in proximity, Sri Lanka and India share many wild species. But as a result of thousands of years of separation due to the sea barrier, Sri Lankan populations of a number of amphibians evolved to become unique to the island.

Tadpole of Microhyla mihintalei – MadhavaM

The Mihintale frog had been previously considered to be a species called Microhyla rubra that is widespread in India and Sri Lanka.

Being a dry zone species, the Mihintale frog has to wait for torrential rains to breed. They lay floating layers of eggs on the surface of rainwater pools. The tadpoles have to be lucky to become transformed into frogs before the water pool runs dry.

The skin of this frog is toxic, so many predators avoid it, giving the species a greater chance of survival.Unlike other endemic frogs, the population of Mihintale frog is considered stable.

The reporting of this endemic species is yet another success story of joint research by Sri Lankan and Indian scientists. The discovery was published in the Zootaxa journal with research being carried out by graduate students Nayana Wijayathilaka, Sonali Garg, Gayani Senevirathne, Nuwan Karunarthna under the supervision of Dr. Madhava Meegaskumbura of University of Peradeniya and India’s frog expert, Prof. S.D. Biju.

There are 118 frogs and toads in Sri Lanka and with the new member, 102 of them are endemic to Sri Lanka.

Bye.. bye.. thinner polythene

The Central Environment Authority (CEA) will from next month systematically begin raiding the manufacturers and sellers that do not comply with the ban on polythene less than 20 microns in thickness.

“In January, we made some raids and those found guilty had been given chance to adjust to alternatives. But from February onwards, we will take legal action against those who do not comply,” a CEA spokesman warned.

The manufacture, sale or use of polythene less than 20 microns in thickness was banned from 2007 under the National Environment Act under the directive of President Maithripala Sirisena while he was the minister of environment but the law has until now not been properly implemented.

The thickness of polythene sheets is measured in microns – a unit resembling 0.001 millimeter. These thinner polythene sheets are mostly used in shopping bags or “sili sili bags”, lunch sheets and other packaging materials.

Any form of polythene or plastic takes hundreds of years to decay, polluting the environment, but thinner polythene is more evil as it cannot be recycled. Burning it causes the emission of poisonous gases such as dioxin, so such polythene ends up in garbage dumps.

Dumped bags clog the drainage system, creating floods. Animals such as cattle also feed on polythene bags found on rubbish heaps and become ill or die.

Easy to transport: A day’s shopping all in ‘Sili sili’ bags

The water collected in these disposed bags and wrappers can collect rainwater, making breeding grounds for mosquitoes that spread diseases such as dengue. Polythene dumped in waterways finds its way into the ocean, choking and killing marine life.

According to a survey conducted by the Environment Ministry 72 per cent of villagers and 49 per cent of people in urban areas in the Western Province use polythene lunch sheets.

In total, about 500,000 metric tonnes of polythene and plastics are imported into Sri Lanka with 70 per cent of this going into domestic use while 30 per cent is used in export-related industry.

The positive side is that about 40 per cent of the plastics and thicker polythene is being recycled. The CEA currently has six recycling plants in operation and two more awaiting commissioning.

About 160 firms involved in plastic recycling are registered with the CEA and this number is expected to increase.

Worryingly, 60 per cent of the plastic and polythene used domestically ends up in garbage.

The authorities hope the ban on thin polythene will be effective. In Bangladesh, which banned the use of polythene bags in early 2000, media reports say polythene is making an illegal comeback.

A change in consumer attitude is key to the success of the strategy. Experts recommend the widespread teaching of the 3R principles: Refuse, Reuse and Recycle.

As consumers, we all have the power to refuse a polythene bag when it is not necessary and we can carry reusable bags.

A whale of a problem; Saving sea giants or saving industry

Scientists and economists debate major step of shifting shipping route

A Blue Whale hit by a ship in Lankan waters

There was heated debate over the problem of saving whales off Sri Lanka from ship strikes as a three-day forum last week heard the faster speeds at which ships now travel pose a heightened danger to these huge endangered creatures.

A major maritime organisation, however, declared none of its members had ever experienced a ship strike on a whale
A busy shipping route runs through the ocean off southern Sri Lanka which has been identified as an area in which the giant blue whale and many other whales are found in abundance all year around.

A proposal by conservationists to shift this shipping route, known as the Dondra Head Traffic Separation Scheme (TSS), 15 nautical miles (nm) southward is hotly opposed by shipping industry representatives who argue the country’s economy would suffer if this were to happen. Some conservationists too question a shifting of the shipping path.

Last week’s consultative forum organised by the Indian Ocean Marine Affairs Cooperation (IOMAC) focused directly on this issue under the title, “The Environmental Health of the Ocean: First International Expert and Stakeholder Conference on Marine Mammals with special Reference to the issue of Ship-strikes and the IMO Traffic Separation Scheme at Dondra Head”.

The Chairman of the Scientific Sub-Committee on Ship Strikes of the International Whaling Commission (IWC), Dr. Russel Leaper, said whenever a whale path overlapped a shipping route ship strikes were possible. As ships become bigger and faster, the time a whale has to dodge an approaching ship decreases so ship strikes have become an increasing threat to whales, Dr. Leaper explained.

Dr. Thilak Priyadarshana of the University of Ruhuna and a group of international researchers who published a paper last year called “Distribution patterns of blue whale (Balaenopteramusculus) and shipping off southern Sri Lanka” advocate moving the shipping lane.

Whale researcher Dr. Asha de Vos too believes the whales off Mirissa are vulnerable to ship strikes. She said the blue whale population off southern Sri Lanka is unique as the whales appear to be staying in our waters throughout the year, a fact that could be attributed to a rich feeding ground.

Dr. de Vos showed the forum photographs of the whale that carried into harbour in 2012 and the horrific underwater images taken by photographer Tony Wu showing a blue whale carcass with a gash cut by a propeller on its tail that could have come from a ship strike.

“Less than 10 per cent of ship strikes are getting reported as the dead whales could sink or be found at a bad stage of decomposition after long time drifting and the reason for the death cannot be confirmed,” she said. “In some cases, in particular involving large vessels, captains might be unaware that a collision with a cetacean has occurred,” Dr. de Vos explained.

“The whales are in these nearshore areas because these areas are productive and have food. Imagine if there was a bus driving through your kitchen, how would you feel? You would have to go there to get food despite the danger of getting hit.

“The solution to this problem is simple. Shifting the shipping lanes a few nautical miles south of its current position will not really affect the shipping industry but will have huge gains for a species that is very valuable to our economy.

In fact, shipping lanes have been shifted to stop ship-whale collisions in many other parts of the world, so Sri Lanka is not doing anything out of the box or innovative. We will just be doing what is right,” Dr. de Vos stated.

Shipping industry representatives at the forum said they feared moving the shipping route would harm associated industries.

The close proximity of the shipping route to the southern coast of Sri Lanka, in between the two major ports of Galle and Hambantota, brings the opportunity of business from ships passing near the service ports, said Captain Ranjith Weerasinghe of the Company of Master Mariners.

“But ‘out of sight’ would result in ‘out of mind’, so a shift would affect Sri Lanka economically,” he told the IOMAC forum.

“Currently about 1,000 ships per month call for services off the port of Galle as a direct result of having the Traffic Separation System in our coastal proximity.

If this route shifted 15nm it would make the westward passage from Rondo Island coming out of Malacca straight through the Bay of Bengal a direct course to the north of the Maldives, making that the obvious position for shipping services, losing Sri Lanka an opportunity,” Captain Weerasinghe pointed out.

“None of our 275 members, the vast majority of Master Mariners of Sri Lanka, whose sea experience ranges from 12-40 years of sailing, has had a ship strike on a whale ever,” Captain Weerasinghe declared.

Based on the University of Ruhuna study, the NGO, Friends of the Sea, lobbied to push the Sri Lankan government into submitting a proposal to shift the shipping route last year but the government wanted to study the proposal further.

“It is true that we need to conserve the whales, but we should also look at our national interest,” said IOMAC Secretary General Dr. Hiran Jayewardene. He called it as a campaign to prevent ships coming to the ports of Sri Lanka.

“We need hard facts to evaluate whether ship strikes are a very frequent occurrence off southern Sri Lanka that can affect the blue whale population,” he said. “Even if we move the lane further south, what is the guarantee that it will not affect other populations of whales?” Dr. Jayewardene said.

The Director of Research of the Centre for Research on Indian Ocean Marine Mammals (CRIOMM), Howard Martenstyn, also said there was not enough evidence to determine the ship strikes is a major threat to whales off Mirissa. Commenting on the 2012 incident where a Bryde’s whale carcass was dragged into harbour on the bow of a vessel, Mr. Martenstyn said that could have been a drifting dead whale carried by the ship.

He said the photograph of a gash wound on the whale could not definitely show whether the whale died due to ship strike or whether a drifting dead whale had been struck with a propeller.

Mr. Martenstyn pointed out there was no significant increase of carcasses found on the southern coast, saying if the whales off Mirissa were regularly hit the number of dead whales found in these areas should show an increase.

Dr. Russell Leaper of the IWC said the accuracy of Sri Lankan whale ship strike records would be reviewed by a panel of international experts over the next few months before being entered into the IWC database and this would resolve some of the confusion between researchers in Sri Lanka over these records.

“Compared to other areas where shipping lanes have been moved to reduce risks to whales, Sri Lanka has a very strong case,” Dr. Leaper said. “Of all the whale and ship strike problems I have worked on in other areas this is probably the clearest case of the highest risk and also the most straightforward action that could reduce risk.

“We see that moving the passing shipping further offshore could only benefit Sri Lanka. As well as protecting whales it would greatly reduce the risks to whale watching vessels. This is an accident waiting to happen which would have serious consequences for Sri Lanka’s tourist industry.

“Shipping safety would also be improved with lower risk to coastal fishing boats, lower risk of collisions between large ships and less chance of oil spills along the coast. It also allows more space closer to shore for ships using Sri Lankan ports.”

Gehan de Silva Wijeyeratne, who led an aggressive media campaign to brand Sri Lanka for whale-watching, said whale-watching generated much more money than whale watching bookings alone would suggest as customers used the full spectrum of accommodation and other services.

“So whale watching is now a key element for tourism in the south and any move to protect these whales is welcome by the tourism industry,” he said. “The Indian Ocean blue whale population is low due to extensive illegal whaling in the Indian Ocean in the 1960s.

Furthermore, like many long-lived animals, population recovery can be slow. Therefore every individual that is saved by reducing ship strikes will help conserve these intelligent and sentient beings and help the livelihoods of people in the south,” Mr. Wijeyeratne said.

Sri Lanka’s whalesNineteen whale species have been recorded in Sri Lankan waters by the Centre for Research on Indian Ocean Marine Mammals (CRIOMM), and there are in total 28 species of marine mammal, including dugong, off our shores.There are two kinds of whales: those with teeth and those that are toothless but have special plates called baleen to filter food. The giant blue whale is a baleen whale. The sperm whale, the largest toothed whale, can live in super pods of more than 100 creatures, a spectacular sight.

Off Mirissa, once in a while, are sightings of orcas or so-called killer whales. This is probably the most intelligent marine mammals and, sadly, is often a feature in large aquariums, trained to perform tricks. They have won hearts in films such as Free Willy.

Whales are slow breeders so if a number of individuals are killed in a short period of time the recovery of the population is slow.


Mini hydros: Clean energy comes at high cost to Nature

Damming streams a ‘death sentence for many species’

Mini hydro plants, touted as clean energy power sources, are destroying eco-systems in some areas, experts warned.

In Sri Lanka, large hydro power potential has all been fully utilised and what remains are opportunities for small or mini hydro power. These smaller plants are blocking streams, threatening freshwater fish and the fragile ecosystem in these water sources, a conference heard last week.

The Dams, Rivers and Freshwater Fish in Sri Lanka conference was organised by the Centre for Environmental Justice (CEJ) to focus particularly on threats to Athwelthota feared from a proposed mini-hydro power plant.

Athwelthota is a paradise for freshwater fish, with a number of species discovered in this unique habitat. The CEJ and the Wildlife Conservation Society of Galle (WCSG) have published a poster showing the indigenous fish that could be endangered by the proposed mini-hydro project in Pilithudu ella, Morapitiya-Athwelthota.

A mini hydro project works by having water in a river diverted to a powerhouse by means of a dam built across the flow. This water rotates a turbine and flows back downstream.

Not all the water can be diverted: a part has to be let flow naturally in the river, according to law. But the change in flow is a death sentence for many species living in this micro-habitat, said Samantha Gunasekera, an expert on freshwater fish and orchids who until recently headed the Customs Biodiversity Unit.

“Different fish need different micro-habitats,” Mr. Gunasekera said. “For example, the gal padiya or sucker fish lives deep in fast-flowing water; some fish species live in relatively calm water while others prefer fast-flowing water. But if part of a stream is diverted the habitat downstream changes and fish will be affected even though a percentage of water might be allowed to flow freely. With flow changes the PH value [acid levels] of water too could change and very sensitive species could become affected.”

“Some fish migrate upstream to breed and when the stream is blocked this movement is disrupted,” WCSG member Madhura de Silva said.
In Athwelthota, 39 freshwater species have been recorded, 20 of them endemic to Sri Lanka.

Most of the mini-hydro projects are being constructed in the biodiversity rich wet zone, so the damage they cause is actually worse than with the large dams, Mr. de Silva said. “Not only the fish but other animals such as amphibians and freshwater crabs too are affected.”

Athwelthota is also home to Sri Lanka’s only aquatic orchid. Near a waterfall lies a special “spray zone” full of water vapour and this special habitat could be totally lost, Mr. Gunasekera fears.

He emphasised the importance of considering the collective effect of all the mini-hydro power plants on a stream or a river when carrying out environmental assessment.

Many streams have been marked as potential for building mini-hydro projects and already about 37 are in construction or evaluation phase, revealed CEJ member Hemantha Withanage.

Environmentalists revealed the damage caused by a number of these projects, among them the mini-hydro plant being built crossing the Anda dola in Dellawa forest close to Sinharaja rainforest and a plant at Koskulana in the northern Sinharaja buffer zone.

The Rainforest Protectors of Sri Lanka says these projects will damage the Sinharaja World Heritage Rainforest complex.

Construction is being carried out in the Northern Sinharaja Rainforest buffer zone at Kosgulana, approximately 4km east from the Kudawa main entrance. A dam is being built blocking the Kosgulana river in Sinharaja buffer zone and several acres of rainforest have been cleared and concrete laid along the once pristine and protected riverbank. Large trucks and machinery used for construction have driven a wide track through what was once a small footpath in the Sinharaja buffer zone, between Kudawa and Kosgulana, the Rainforest Protectors say.

Anda Dola, a tributary of the Gin Ganga in the Neluwa Divisional Secretariat in Galle district, is the latest victim of the rapidly multiplying mini-hydro projects throughout the wet zone.

The weir and a 2.5 km section of penstock (concrete channel) has been constructed within the Dellawa rainforest, which is ecologically part of the Sinharaja Rainforest Complex. Due to construction happening within the protected forest reserve and negligence in part by the developer, the project is said to be causing massive environmental destruction affecting the stream, rainforest, soil and endemic fish in the region.

The mini-hydro project will destroy a total 6.5 km stretch of the Anda Dola as water is being diverted from the weir to the powerhouse, several kilometres away. This will result in the local extinction of many endemic and endangered fish species recorded in the Anda Dola.

Environmental lawyer Jagath Gunawardene said project in such an environmentally sensitive area needs to undergo proper environmental assessment.

The Central Environment Authority (CEA) bears a significant responsibility to make sure Environmental Impact Assessments are being conducted thoroughly and to make certain the recommendations of the EIAs are being implemented. CEA chairman Professor Lal Dharmaratne said his institute would take action against those who violate the law.


Shark spotted in Menik Ganga

This article was published on 16.02.2016 on SundayTimes – http://www.sundaytimes.lk/160214/news/extinct-shark-spotted-in-menik-ganga-182906.html

A few months ago, the apex predator of the freshwater riverine habitats, the crocodile, was reported in the sea off Wellawatte; recently the apex predator of the ocean, the shark, was reported in a river. The latest sighting of a shark in a freshwater habitat was reported by a group of wildlife lovers who visited Yala on January 23.

While travelling to their campsite in the evening they passed a bridge over the Menik Ganga that flows across Yala. The slow-flowing water in this part of the river is shallow and one of the group members spotted a large fish.

“That is a shark!” shouted Isuru de Soyza, pointing it out to the others before it swam away. Senehas Karunaratne, armed with a camera, had only a split of second to click before the shark took refuge under the bridge.

“The shark was about three feet long and quick in the water,” commented Mr. Karunaratne.

Rumours of sightings of sharks in the Menik Ganga have been around for a while and Mr. de Soyza claimed to have seen one in the same section of the river a few months ago.

Photographic evidence of sharks in the Menik Ganga first came from a team from the Wildlife Conservation Society of Galle (WCSG). While conducting an islandwide freshwater fish survey at the Menik Ganga about 7km upstream from the coast they spotted a shark in shallow, crystal-clear water about three feet deep.

They netted the shark and carefully brought it out of the water to take measurements. The shark was about three feet long. After photographing it, they released it back into the water.

The WCSG survey team had three more sightings of sharks in the Menik Ganga and the Kumbukkan Oya, closer to Kumana.
Sri Lanka’s foremost expert on sharks, Rex I. de Silva, was sent the WCSG photo for examination and identified the shark as a variant of the Pondicherry shark (Carcharhinus hermiodon).

This species lives in the Indo-Pacific region from the Gulf of Oman to New Guinea, with most records from the coastal waters of India. The International IUCN Red List of threatened fauna lists the Pondicherry shark as “Critically endangered – possibly extinct”.

The Red List states that the shark was last recorded in 1979. Rex de Silva, however, states that the shark has been recorded in small numbers in Sri Lankan seas since the mid-1980s with the species’ presence in Sri Lankan waters first documented by himself in 1988.

Commenting on these sightings on the “Sharks of Sri Lanka” Facebook page, Mr. De Silva said it was important to differentiate between a shark in freshwater from a shark in a river.

“In times of drought, when river levels, fall seawater may intrude some distance up rivers at high and especially spring tides. Sharks and other marine species may follow the seawater intrusion for a considerable distance up river, so although they are in a river they will still be in salty or semi-saline water.

When the salt water recedes the marine species follow it back to the sea. A shark in freshwater, on the other hand, is usually present farther up a river beyond the reach of salt water. As mentioned above, the shark photographed by the Wildlife Conservation Society of Galle to date remains the only record of a shark from freshwater in Sri Lanka.”

Mr. de Silva states that anecdotal evidence over at least 30 years suggests that there are sharks in the Menik Ganga, but these sharks were not identified although speculation about their identity was sometimes offered.

Literature indicates that Pondicherry sharks do not grow much longer than about 3.3 feet and hence are not a threat to humans.

Sharks are not blood-thirsty man-eaters as Hollywood movies depict, so the presence of sharks in the Menik Ganga simply adds an interesting element to Sri Lanka’s biodiversity and is nothing about which to feel panic.

A fisherman in Hikkaduwa caught a 12-foot, 350kg shark, reports last week said.

The shark was caught in deep ocean about 20 km from shore. Inspecting footage of the specimen, shark expert Rex De Silva provisionally identified it as a bull shark (Carcharhinus leucas).

Help for identifying a sharkAltogether, 61 species of shark have been found around Sri Lanka, however there could be more varieties living in our waters. Shark expert Rex de Silva maintains a Facebook group called “Sharks of Sri Lanka” and welcomes public sharing of images for identification purposes.

When forwarding images for identification it is best that a full lateral view (side view) is submitted as correct identification often depends on the relative positions of the fins, size and position of gill slits etc.

“I appreciate that obtaining a lateral view will not always be possible in which case any image is better than none and I am pleased to note the great interest in our sharks among lay persons,” Mr. De Silva states.

Mr. De Silva also launched a comprehensive book on sharks last year, with illustrations by prominent wildlife artist Jayantha Jinasena. Copies could be purchased from the Field Ornithology Group of Sri Lanka (FOGSL), Department of Zoology, University of Colombo (call 2592609 or email fogsl1976@gmail.com

 



A Thought for World Environment Day 2016…!!

Today, 5th of June is the World Environment Day 2016. I had a little field visit to the neighborhood land in the morning with my little ‘birding companion’ to feel the nature to celebrate the day. The land was full of grass that still holds silvery morning dew. As we walked in, grasshoppers that disturbed by our foot movements jumped out on different directions. Butterflies were seeing flying from one wild flower to another in search of nectar. A lonely lizard basking the rays of morning sun was watchful, but did not make a move by our presence. My little daughter was excited as many of these things in the nature were new to her. She had quickly find friendship with mimosa (නිදිකුම්බා) shrubs found plenty in the land. She started enjoying kicking mimosa shrubs one after another watching joyously how the leaves go to sleep by her touch. She also liked its flower and plucked few, showing me her priced collection.

‘Nature’ is indeed a wonderful thing, but we often ignore the beauty of its little things still survive around us. Hope my little daughter and all the kids in the world would get more chances to experience the joy of nature and they will not destroy nature, but protect it when they grow up. This is my World Environment Day wish..!!

Prof. Savitri Gunatilleke with her PhD “guru”, Prof. Peter Ashton, and her husband, Prof. Nimal Gunatilleke, holding the plaque for the award of an Honorary Fellowship of the Association of Tropical Biology and Conservation

The Association for Tropical Biology and Conservation (ATBC), the premier global organisation with a mission to foster scientific understanding and conservation of tropical ecosystems, has awarded its 2016 Honorary Fellowship to Professor Savitri Gunatilleke, Emeritus Professor at the University of Peradeniya.

Prof. Gunatilleke is the first Sri Lankan to receive this award, made at the ATBC’s 53rd Annual Congress in Montpellier, France last month.

The award is given to researchers who have demonstrated life-long distinguished service to science and have been an inspiration and role model for younger scientists and students of tropical biology.

The ATBC said Prof. Gunatilleke’s selection was unanimous, with nominations including researchers from the United States, United Kingdom, India, France and Indonesia.

Founded in 1963, the ATBC Honorary Fellowship Award is considered one of the highest accolades a researcher in the field of tropical biology can receive, with more than 80 scientists around the world being honoured so far – of whom only six have been women.

The main area of Prof. Gunatilleke’s research has been the Sinharaja rainforest. In the 1970s, the Sinharaja forest was logged by the state forestry enterprise. Her research and conservation promotion contributed in large part to the eventual designation of the Sinharaja as a World Heritage Site.

Prof. Gunatilleke graduated with a first class honours degree in Botany from the University of Ceylon in 1969. She completed her MSc in Ecology, and also obtained her PhD – on a paper entitled “The Ecology of the Endemic Tree Species of Sri Lanka in Relation to their Conservation” – in 1975 from the University of Aberdeen under the supervision of the world-renowned tropical forest expert, Professor Peter Ashton.

“In fact, I wanted to study plant pathology – the science of studying causes and effects of plant diseases – but Professor B.A. Abeywickrama, then head of the Botany Department at Peradeniya, suggested I study forest ecology. It was a decision that changed my academic career,” she said.

The higher studies were challenging for the shy research student. “Quite frankly, I had not been to a forest when I started my PhD studies and I hardly knew how to identify different plants in the field. So I had to learn fast but luckily I had supportive local supervisors,” Prof. Gunatilleke.

She pays tribute to her undergraduate teachers, professors M. D. Dassanayake and S. Balasubramaniam, who helped her tremendously to gain this knowledge during her formative years.

As the distribution patterns of Sri Lanka’s endemic tree species growing in the different lowland climates unravelled during her Ph.D. field research, Prof. Gunatilleke’s bond with the forests grew. She pays tribute to her team of field researchers and field assistants for her success.

Later, she tied the knot with another academic in the field, Prof. Nimal Gunatilleke. “Nimal has been of great strength to me,” she said, adding she was lucky to have a research partner at home.

Prof. Gunatilleke was a pioneer in taking university students to the field for forest studies. Earlier, the practice was that even forest ecology had been taught in the classroom without stepping into a forest.

When asked why that practice could not continue, she was persuasive. “Sri Lanka’s forests are among the best ‘outdoor laboratories’ to study biological diversity. But it was a time that the university had limited resources so we had to push the administration to convince the importance of these field studies,” Prof. Gunatilleke said, recalling the time she introduced “multi-day” field courses to her students.

Prof. Gunatilleke has a long history of mentorship of a younger generation of Sri Lankan tropical scientists, with a number of them serving in reputed international and national institutions.

Savitri  Gunatilleke is an outstanding role model for scientists in Sri Lanka and women scientists in particular. Apart from her academic work, which is evident from her many influential publications, she also committed herself to the advancement of ecology and conservation in Sri Lanka’s development. She has been a member of Sri Lanka’s National Man and Biosphere committee and helped to prepare the country’s Biodiversity Action Plan (1997) to name but two of many contributions.

Wildlife activists have welcomed Cabinet’s decision this week to have a herd of 35 captive elephants from Pinnawela trained to take part in cultural events while under the care of the Department of Zoological Gardens.

The move follows a proposal submitted by the Minister for Wildlife, Gamini Jayawickrama Perera in the aftermath of the seizure, from private owners, of some 30 elephants believed to have been caught illegally from the wild. Preliminary investigations into this matter have been completed and the elephants, of varying ages, have been transferred to a facility in the Elephant Transit Home (ETH) in Udawalawe.

Forces opposing the confiscation of the elephants began a campaign of fear that the confiscations would disrupt cultural events, claiming even major events such as the Temple of the Tooth perahera would be threatened due to lack of elephants for the processions. There have even been claims that wildlife activists and conservationist groups were being bribed by western countries to disrupt Sri Lanka’s cultural life.

The setting up of a unit of trained elephant to be used for cultural events was first proposed by a former director of the Zoological Gardens, Brigadier H.A.N.T. Perera but was blocked by captive elephant owners, and the former government was not interested in implementing the proposal.

The Director at Species Conservation Centre, Pubudu Weeraratne, who voiced the need to bring those behind the jumbo racket to justice said keeping trained elephants at the Pinnawela Elephant Orphanage was the best solution. “This solution will help the elephants’ welfare and they will get the chance to move around with other elephants when there is no work,” Mr..Weeraratne said.

The elephant calves have to be sourced only from Pinnawela and not from the Elephant Transit Home, Sajeewa Chamikara of the Environment Conservation Trust emphasised.

The Pinnawala orphanage was started as a facility to house elephant calves found abandoned or orphaned in the wild. But since 1995 all such orphaned elephants are housed at the ETH with the intention of rehabilitating them and releasing them back into the wild. To take an ETH elephant for training would be to deny its chance to return to the wild, Mr. Chamikara said.

Pinnawela has now has become an elephant management centre, with several births annually, and as the animals there have more interaction with humans activists agree it provides best option as a source of calves to be trained for use in pageants.

Prior to Cabinet’s decision this week, the Secretary of the Tamed Elephant Association, Dhamsiri Bandara Karunaratne, told media there was a dire need to have more captive elephants trained for cultural events and that the removal of 30 captive elephants from private hands had left a large void. He said that while there were 19 tuskers among Sri Lanka’s captive elephant population only three were suitable for carrying the relic casket of the Temple of the Tooth.

The veteran environmental lawyer, Jagath Gunawardene, said the wildlife activists’ fight was only against the illegal capture of animals: they were not opposed to using elephants for major cultural events.

“Even by the Flora and Fauna Protection Ordinance, which is the main legal document, the using of elephants for the main cultural events is honoured. We never proposed anything to block the elephants from being used in cultural and Buddhist events,” emphasised Mr.Gunawardene, saying those who wanted to keep elephants in private hands for their own satisfaction were trying to hide behind religion.

“We know that traditional elephant owners too get into some difficulties. But it is mainly due to those who acquire these elephants illegally” he concluded saying that the justice should be delivered without delay.

“Don’t use the Dalada Esala Perahera for to let the elephant thieves escape,”  the Anti-Corruption Front’s Ulapane Sumangala Thera said in a separate interview.

Thousands of years old ‘near fossilized’ animal remains found in Yala

$

Bone fragments believed to be animals that died thousands of years ago were discovered from a rock pool in Yala this week.

They are parts of skeletons of elephants, tortoises, wild buffaloes, spotted deer, wild boar and other animals, say students of the Kelaniya University Postgraduate Institute of Archaeology who are studying the fossils.

The level of fossilisation indicates the animal bones are 1,000 to 5,000 years old, palaeobiodiversity expert Kelum Manamendra-arachchie said.

“Some of these bones could be older,” he added. With time, the organic materials inside bones are replaced by mineral substances and experts can estimate their age by observing the extent of this fossilisation process.

Fossilisation only happens in rare cases. Animal carcasses are usually eaten or bacteria can rots them away before fossilisation can occur.

Fossils are found when animals die in location where their carcasses – or parts of it – are protected from scavengers and the elements, such as when they are found on the seabed or a river bed and become buried in sand, soil or mud. Rock pools with beds of clayey mud are ideal, Mr. Manamendra-arachchie pointed out.

The bones were found during efforts to find water sources for thirsty animals. Due to the drought, many of the Yala National Park’s waterholes have run dry. The Department of Wildlife Conservation (DWC) sent a crew with a backhoe to deepen a rock pool known as Wel-mal-kema in Yala Block I.

These rockpools are the lifeline of wild animals during droughts as many of them have water when other water sources run dry. It is believed animals became trapped in the mud of this rock pool when they came there for drinking water thousands of years ago.

Through analysis of the bones, Mr. Manamendra-arachchie is able to surmise that wild buffaloes were plentiful thousands of years ago in Yala. The national park has a population of wild buffaloes but these are mixed with domesticated buffaloes. Mr. Manamendra-arachchie says the base of the hobes are thicker in wild buffaloes and there were many such skulls among the excavated bones.

This Wel-mal-kema is 30 feet long and believed to be 30 ft deep. Only half of it has been excavated and it is possible that there could be much older fossils.

Yala has a number of such rock pools, so there could be many mysteries waiting to be unearthed. The Director-General of the DWC and the Minister for Wildlife has requested the Institute of Archaeology to continue with this study in Yala.

Mr. Manamendra-arachchie said he analysed a similar, but smaller rock pool in 2005 in Thanamalwila from which he collected four truckloads of bones that, he believes clearly accounted for more than 100 elephants, 150 wild buffaloes, 200 spotted deer, 150 wild boar and 50 sambhur deer. Most of them had almost become fossilised.

What price for Nature’s ‘greenbacks’ – the forests?

$

Prof.Nimal Gunathilake

Conservationists are debating whether working out a rupee value for forests would convince money-crunching bureaucrats that preserving them makes more economic sense than stripping woodland for income-producing purposes.

“Many people consider forest as a waste of land where utilising that terrain for other purposes can bring income, also contributing to the national economy. But forests provide other services such as delivering the fresh water we drink and the clean air we breathe whereas if we lose these services it will cost a lot of money to implement costly alternatives,” the Conservator-General of Forests, Anura Sathurusinghe said.

“It is often a big challenge to communicate this value to politicians and officials who mainly understand the value of everything in monetary terms and demand forest land for other development work,” Mr. Sathurusinghe said at a press conference organised by REDD+ Sri Lanka regarding the forthcoming International Research Symposium on Valuation of Forest Ecosystems and Their Services to be held in Colombo on October 18.

REDD+ (Reducing Emissions from Deforestation and Forest Degradation) is an effort to identify value for the carbon stored in forests, offering incentives for developing countries.

“Tagging a value” for services provide by an ecosystem such as a forest is a modern concept. Ecosystem services are broadly divided into four categories: provisioning, such as the production of food and water; regulating, such as the control of climate and disease; supporting, such as nutrient cycles and crop pollination; cultural, such as spiritual and recreational benefits. The concept aims at putting a price tag for these services which helps to convey their values in monetary terms. Hence the price that has to be paid by destroying that particular forest is highlighted.

“We know about ‘provisioning’ values of forests such as the value of timber, but other services are often taken for granted,” said forests expert Professor Nimal Gunathilake. He explained the aims of the research forum were to share the existing knowledge on forest ecosystem services valuation, identifying new methodologies and identifying the drawbacks.

Conservator General of Forests Anura Sathurusinghe

Ecosystem valuation can be difficult and controversial, and economists have often been criticised for trying to place a “price tag” on nature. At the forum, a question was raised whether communicating the value of individual forests to the general public is prudent as people could start exploiting natural resources such as in the case of illegally stripping forests of “walla patta” trees and smuggling the resin-rich wood overseas.

Mr.Sathurusinghe revealed that a recent review of forests showed degradation was a bigger concern than deforestation. Deforestation means conversion of forest to another land use type while degradation is deterioration of the standing vegetation in density, structure and species composition due to human activities and natural causes.

The four main causes of deforestation are encroachment, infrastructure development projects and private agriculture ventures while drivers for forest degradation include illicit felling of trees, cattle grazing, forest fires, gem-mining, quarrying, forest undergrowth cultivations such as cardamom and non-timber forest product gathering such as weniwel or walla patta. A REDD+ Sri Lanka report states Anuradhapura is the district with the highest levels of deforestation and forest degradation.

Deforestation is taking place at a relatively higher rate in the dry zone due to the many development projects now occurring there. Experts cautioned that dry zone forests are as important as wet zone forests.

Ecological survival a shared responsibility

World Bank binds communities into visionary project – published on SundayTimes on 18.09.2016

Sri Lanka and the World Bank have signed a $US45 million loan to help protect the country’s natural habitat and resources from degradation and over-exploitation. The Ecosystem Conservation and Management Project (ESCAMP) aims to address key issues in conservation while assisting to improve the lives and livelihoods of neighbouring communities.

ESCAMP was initiated in 2009 when the former Rajapaksa government asked the World Bank for a $US30 million loan. The bank, with assistance of number of experts, come up with a proposal including a science-based action plan to address number of conservation issues including the Human Elephant Conflict (HEC) in selected areas.

Conservationists had high hopes for ESCAMP as a landmark project but in the latter stages of negotiation the Ministry of Finance requested fundamental changes and the World Bank decided to drop the project in 2011, fearing the changes would harm its objectives.

The Sirisena government showed interest in reopening the project and made a formal request. After updating the proposal both the WorldBank and Cabinet signed approval of the project on September 5. Most of the main components remain intact and this time the amount being given is $US45 million.

“The project will improve responsible planning and management of protected areas and other biologically and ecologically important locations throughout Sri Lanka,” said World Bank Senior Environment Specialist and Project Task Team Leader Darshani De Silva.

Importantly, it will create partnerships of environmental guardianship with local communities, she said. “It will help to create sustained linkages with communities living adjacent to protected areas to ensure participation in protection of critical ecosystems and benefit sharing, promote compatible developments within and around sensitive ecosystems, raise quality of visitor services and revenue potential of forest and wildlife resources, while developing the capacity of Forest Department and Department of Wildlife Conservation to deliver on their institutional mandates.”

There are four main components. One is a Pilot Landscape Planning and Management for Conservation scheme in two particular areas in the dry zone and biodiversity-rich wet zone. The second component, Sustainable Use of Natural Resources and Human-Elephant Co-Existence, includes financing the scaling-up of successful human-elephant coexistence pilot projects along with identifying economic incentives for affected communities.

The third component, Protected Area Management and Institutional Capacity, has the biggest funding allocation, $US 24.2 million. It aims at supporting the Protected Area (PA) network, support of nature-based tourism development and strengthening of the institutional capacity and investment capability for conservation and management. Project management is funded as the fourth component.

Conservationists view ESCAMP positively as it clearly looks at long-term solution for many issues including human-elephant conflict. The proposal clearly specifies that project funds should not be used for failed solutions such as elephant drives or the capture and domestication of problem elephants.

The Ministry of Mahaweli Development and Environment will lead the implementation of the project in partnership with the Ministry of Sustainable Development and Wildlife. It is expected that ESCAMP will conclude in 2021.

Drug will for the first time counter kunakatuwa bites : Published on SundayTimes on 09.10.2016 http://www.sundaytimes.lk/161009/news/trials-to-start-for-home-grown-anti-venom-211742.html

Researchers at the University of Peradeniya will next week begin clinical trials for new snake anti-venom that experts

Prof. Indika Gawarammana

Prof. Indika Gawarammana

hope preclude the high rate of allergic reactions from imported medication.

Indian-manufactured anti-venom serum is the main weapon used against the 50,000-plus snake bites recorded annually in Sri Lanka but as venom varies in snakes of different countries the Indian anti-venom has limitations here.

As this paper reported recently, Indian anti-venom could cause adverse allergic reactions in 50-80 per cent of patients, with nearly half of these reactions life-threatening. Most Sri Lankan doctors see the solution (anti-venom) as a bigger challenge than snakebite itself.

“All laboratory tests have now been completed and the results show that the new anti-venom is far superior in terms of neutralising venom compared to the Indian anti-venom,” the team’s chief scientist, Professor Indika Gawarammana, said.

“After the safety and effectiveness of the new anti-venom is established following clinical trials, commercial manufacturing can be started.”

The research team received the first batch of the anti-venom processed by its collaborator, the Instituto Colodomiro Picardo (ICP) of the University of Costa Rica a few weeks ago and are now ready to begin clinical trials, said Prof.Gawarammana, who is Senior Lecturer at the Faculty of Medicine at Peradeniya.

First batch of anti-venom for our own snakes

First batch of anti-venom for our own snakes

The anti-venom is active against number of venomous snakes. The first test batch will be effective against venom from the cobra, Russell’s viper, saw-scaled viper and the hump-nosed viper (kunakatuwa). Anti-venom properties for the krait will, in time, be included in this serum.

The hump-nosed viper (Hypnale hypnale) is responsible for the highest number of snake bites in Sri Lanka and these can sometimes be fatal. Currently, there is no venom to treat kunakatuwa bites and victims are only treated with symptomatic treatment such as painkillers. Records show an unfortunate proportion of patients develop chronic kidney failure due to lack of an anti-venom.

The process of anti-venom development is complex. First, tiny amounts of venom are injected periodically into horses. Horses subsequently develop antibodies – a process similar to immunisation of children for various infections (polio, measles etc.) – in their blood.

These antibodies, the anti-venom, are then extracted, purified and freeze-dried for human use. If the purification is faulty the resulting substance could contain other serum proteins that could cause the problematic reactions coming from Indian anti-venom, Prof. Gawarammana explained.

The researcher recalls how the project began: “In October 2013, Ministry of Health of Sri Lanka invited Sri Lankan scientists, including myself, to produce safe and specific anti-venom for Sri Lanka.

“At our request, one of the best anti-venom producers in the world, Instituto Colodomiro Picardo (ICP) in Costa Rica, agreed to produce a test batch of Sri Lankan species-specific anti-venom at almost no cost,” Prof. Gawarammana  said.

The ICP produces anti-venom for many South America and African countries and Papua New Guinea and these countries do not experience the problems seen in Sri Lanka from anti-venom. Recognising the value of the Peradeniya team’s work, the National Research Council of Sri Lanka provided part of the funding for the project. The rest of the funding came from Animal Venom Research International, a non-profit organisation based in USA.

The necessary permission to collect snakes and house them in a serpentarium, milk venom and export venom to Costa Rica was given by the Department of Wildlife of Sri Lanka.

The project was not without challenges. The team faced unnecessary delays due to adverse media publicity at the inception of the project. As well, researchers only received permission to collect snakes from home gardens to extract venom.

Prof. Gawarammana said ICP was ready to transfer the technology for making the anti-venom to Sri Lanka. He said the researchers do not mind who manufactures it as long as they realise their dream of seeing it save lives.

UNESCO chief Irina Bokova

“Science holds answers for many of the key questions of sustainability we face today and science needs to be more strategic and tightly connected with national strategies,” UNESCO’s Director-General Irina Bokova, told a forum of about 200 scientists in Colombo.

The event last week was organised by the National Science Foundation (NSF) as a dialogue between Sri Lankan scientists and the visiting DG of UNESCO. Ms.Bokova acknowledged the talent of Sri Lankan scientists and invited them to use UNESCO platforms more effectively for their work.

Participating scientists spoke out about barriers to research in this country, saying lack of funds and high-calibre science projects hurt the quality of research in Sri Lanka.

Taking oceanography as an example, Professor Ruchira Kumaratunga, who established the country’s first university Oceanography Department at the University of Ruhuna, said, “The equipment and other services needed to carry out oceanography research is costly. We have buildings, but it is difficult to get these fully equipped with the funds we receive. We also have research vessels, but fuel is costly. Even a diving licence is costly”.

The Minister of Science, Technology and Research, Susil Premajayantha, said the government is to set up a National Science Centre in Colombo to exhibit and celebrate the beauty and wonders of science. Such centres exist in most South Asian countries as well as in the developed world. Ms.Bokova pledged that UNESCO would support the project.

It was essential to attract more talented Sri Lankans to science, Minister Premajayantha said. “You don’t find as many scientists of very high calibre as we had in the past so we have a duty to popularise science, technology and innovation,” he said.

Ms.Bokova also visited three of Sri Lanka’s eight World Heritage Sites, including the ancient city of Polonnaruwa, the Sigirya Rock Fortress, and the Dalada Maligawa in Kandy. She had to face a barrage of questions relating to the status of the Dambulla Rock Cave Temple, a UNESCO Heritage Site.

Asked whether it would lose its status due to unapproved development work carried out by a local monk, Ms.Bokova said a UNESCO technical team that inspected the site in March 2015 had made a number of recommendations and UNESCO was working with the government in order to improve the conservation and management of the site. At the moment, there are no plans to delist Dambulla, she said.

Ms.Bokova, who met President Maithripala Sirisena and other leaders, said she was “impressed by the strong political will to move forward and go through the reconciliation process”.


Wildlife desperate for water

Safe waterholes dry up, driving animals into human areas 

Poachers are heavily active during the drought – Hambantota

As the drought worsens, not only humans but wild animals too are suffering, reports Malaka Rodrigo

A family living in Hathporuwa, Sooriyawewa, had an unexpected visitor early morning on September 20 – an eight-foot crocodile. The family alerted Hambantota wildlife rangers who promptly responded. Later the same day, the same team of rangers had to rescue another croc, a 9.5 footer, from an agro well in Meegahajadura. As the smaller water holes dry up, wild animals looking for water are increasingly straying into human settlements.

Hambantota wildlife rangers also revealed an increase in elephants infiltrating villages and raiding crops as the drought progresses. Most of the small tanks in the pockets of forest patches had dried out so animals – particularly elephants – were moving to the remaining water sources such as Bandagiriya Wewa.

These, however, are now surrounded by cultivations, most established illegally, so the elephants now have to move through villages to get to the water, intensifying the chance of human-elephant conflict.

The dry period is a merry time for poachers. They use inhumane methods such as poisoning the remaining waterholes, bringing death to the unsuspecting animals.

The wildlife rangers and Special Task Force police nabbed three poachers at Kadawara Wewa in Hambantota this week, finding the bodies of two spotted deer they had killed. They also found different kinds of traps set up near the waterhole to capture wildlife – mainly deer.

Deer and other small animals have other new threats. As safe waterholes dry up they have to venture into more open areas. Groups of feral dogs learn to hunt these weakened animals. Hambantota wildlife officers this week found a dead deer that had been attacked by feral dogs.

The media officer of the Department of Wildlife Conservation (DWC), Hasini Sarathchandra, said the department was arranging more patrols in protected areas during this dry period but with a large pockets of unprotected areas outside national parks and only a few dozen wildlife rangers available for deployment it was impractical to expect matters to improve as the drought continued. Not only Yala, near Hambantota, but also Wilpattu and Kumana are experiencing drought.

Yala National Parks Warden D.P. Siyasinghe said this is the typical dry period Yala experiences every year. “Many of the small water pools have gone dry but there are number of large tanks and rock pools that still contain water. The department is also putting water into some of the waterholes and, with the use of solar power, some waterholes get water pumped from the river that still has water,” he said.

The Sunday Times learned that the DWC with support from Linea Aqua, last year rehabilitated a number of tanks inside Yala that helped to increase water capacity and retention so that rainwater is held for a longer period.

Some wildlife experts are of the view that drought is a natural process and we should not interfere too much with it. Late Childers Jayawardene, who was Yala Park warden in the late ’70s, earlier said “drought is nature’s way of maintaining life”.

“Drought eliminates the sick and weak animals. Next year, after the drought, what we have is a healthier animal population. Drought is nature’s way of maintaining life,” Mr. Jayawardene said. Hence mechanisms to minimise the damage from drought should be carefully considered.

Elephant expert Dr. Prithviraj Fernando pointed out that food was a bigger concern than water during a drought. An average elephant spends 16-18 hours a day grazing as it requires about 150kg of food, so a dry period is a testing time for elephants particularly restricted into a smaller area.

Dr. Fernando pointed out that many of the national parks have more elephants than their vegetation can support during drier period, so it is important that animals be able to roam in adjacent forests to assuage their hunger. As the national parks are surrounded by electric fences, however, the elephants’ movements were restricted.

“Sadly some of these fences erected between national parks and wildernesses belong to the Forest Department. It is important these fences be readjusted if we need to have a healthy elephant population in national parks such as Yala and Udawalawe,” he advised.

Dr. Fernando also said the plan to keep the Minneriya tank at spill level throughout the year for irrigation should be reconsidered in order to manage habitats for elephants in drier periods.

Hundreds of elephants in the area gather during the dry season around the Minneriya tank bed to feed on fresh shoot of grasses that come up as the water level recedes. If the Minneriya tank was at spill level all year round a large amount of these grasslands that emerge during the dry season will be submerged, depriving elephants of this nutrition-rich fodder.

Without this fresh source of food during drought, conflict will increase, Dr. Fernando warned, urging authorities to rethink the strategy.

Herpetologist Mendis Wickramasinghe who revealed a brightly-coloured new tree snake from the Sinharaja forest last week has now announced the discovery of a new endemic gecko, found in the Salgala forest in Kegalle district.

The gecko, or huna in Sinhala, is a familiar creature: most of our houses are inhabited by a family of “house geckos” that mostly come out at dusk. The new gecko is different, being mostly active during the daytime. It prefers rocky habitats and is also smaller than the house gecko.

The researcher first found this Salgala gecko in 2012 while exploring the least explored areas of the country to fill in the gaps in knowledge on the reptiles and amphibians that live in those habitats. The research team found a healthy population of this gecko living in the wild around the Salgala area and also inhabiting outer walls of some of the houses close to the forest.

The new gecko is scientifically described as Cnemaspis rajakarunai, named in honour of Henry Rajakaruna, one of the masters of Sri Lankan photography, in recognition of his services to promote Fine Art Photography for over half a century. Mr.Rajakaruna perfected a technique of low shutter speed motion capture internationally known as “Rajakaruna style”.

In common language the Salgala gecko is called  Rajakarunage diva huna, Rajakaruna pahalpalli and Rajakaruna’s day gecko in Sinhala, Tamil and in English, respectively.

Geckos are interesting creatures: they lack eyelids and have a transparent skin that they clean by licking. It also has a well-known defence mechanism of being able to lose its tail. While a predator is distracted by a still-alive detached tail, the gecko is able to hide in a safe place and, in time, grow a new tail.

Geckos move upside down on ceilings using specialised adhesive toe pads that enable them to climb smooth, vertical surfaces. Geckos shed their skin and, it is said, is able to replace each of their 100 teeth every three to four months.

The new discovery brings to 45 the number of gecko species in Sri Lanka. There are about 1,500 species worldwide.

 

Salgala, where the new discovery was made, is a few kilometres away from Galapitamada, where the critically-endangered freshwater fish, bandula barb, has its sole habitat. Salgala is an unprotected forest patch, and that is of concern to researchers. Mr. Wickramasinghe said there was an urgent need to survey the unprotected ecosystems there since other new species awaiting discovery could perish if the habitat was destroyed.

Mr.Wickramasinghe’s work has been assisted by the Ministry of Environment, the Nagao Natural Environment Foundation and principal sponsor, Dilmah Conservation. Dulan Vidanapathirana and Gayan Rathnayake helped him with the research.

This article published on SundayTimes on 31.07.2016 will be re-posted here to remind the importance of our forests on this October – National Tree Planting Month. It is also a tribute to the ‘International Research Symposium on Valuation of Forest Ecosystems’ which is an initial step taken by REDD+ to assess the true value of the services silently offered by our forests. http://www.sundaytimes.lk/160731/news/expert-urges-lankans-to-recognise-value-of-our-forests-202848.html

The world is losing forest at the rate of 3 million hectares a year according to 2010-2015 figures, the UN Food and Agriculture Organisation (FAO) revealed as World Forestry Week was marked in Rome on July 18-22. Minister Susil Premajayantha attended the Rome forum on behalf of the President of Sri Lanka.

Sri Lanka needs to pay more attention to the restoration of its own degraded forest land, Emeritus Professor at University of Peradeniya, Professor Savitri Gunatilleke said.

“Forests fulfil a series of ecosystem services, both tangible and intangible, and it is vital that we recognise their importance,” said Professor Gunatilleke, who recently received an award for her contribution of studies of forests in Sri Lanka.

“Methods are being explored to provide monitoring values for different ecosystem services the forests provide, which we take so much for granted. Hopefully this might convince decision-makers why forests need to be conserved,” she said.

Prof. Gunatilleke highlighted the importance of using Sri Lanka’s forest resources sustainably.

“In recent times, a number of forest species with economic value, such as walla patta, weniwel and kothala himbuttu were illegally and unsustainably harvested directly from forests. Over-exploitation threatens their survival so we need to do something immediately to arrest the situation,” she said.

She emphasised the importance of scientific studies to support a strategy to conserve such plants. “If we know the conditions required for their propagation and growth, these plants can be cultivated so that the pressure on plants in natural forests is reduced,” she said.

“Plants such as cinnamon were previously harvested directly from forests but these are now successfully cultivated, so why not do this for the other heavily harvested forest species? It is worth a try,” Prof. Gunatilleke said.

There is emerging molecular evidence now that some groups of rainforest plants such as the ancestors of durians, rambutans and dipterocarps (the hora and thiniya-yakahalu dun group of species) migrated to South-East Asia via the Indian Plate when earth is undergoing changes some 40-50 million years ago.

Currently, these ancestral species are confined to south-west Sri Lanka, where an ever-wet climate prevails. “These rainforests are a refuge to these ancestral species as well as a host of others, and hence of great significance to the entire tropical Asian region,” Prof. Gunatillake said.

Her research reveals that about 60 per cent of the tree species in Sri Lanka’s lowland rain forests is endemic but that their distribution is highly localised, with most being quite rare. Continued deforestation and illicit encroachment could threaten the survival of such species, she fears.

These wet zone forests are small in size, very fragile, much fragmented and in constant danger of conversion to other uses. It is important therefore to link these remaining forest patches and restore degraded forests using sound ecological principles, the researcher advises.


Battle for solar energy begins

Published on SundayTimes on 11.09.2016 http://www.sundaytimes.lk/160911/news/battle-for-solar-energy-begins-208386.html

The government this week launched Soorya Bala Sangramaya (Battle for Solar Energy) with President Maithripala Sirisena inaugurating the programme by lighting his official residence with solar power.The government said it expects the programme to add 200 MW of solar electricity to the national grid by 2020 and 1000 MW by 2025.

A community-based power generation project launched by the Ministry of Power and Renewable Energy, Soorya Bala Sangramaya promotes the installation of solar panels on the rooftops of households and institutes such as religious places, hotels, commercial establishments, and industries, and the buying back of excess power for the national grid.

Solar electricity customers can connect their own onsite generation system to the utility grid and receive credits on their electricity bills for their excess renewable energy generation.Ceylon Electricity Board (CEB) and Lanka Electricity Company (Private) Limited (LECO) consumers are given options from three schemes: Net Metering, Net Accounting and Micro Solar Power Producer.

Under the Net Metering scheme, the consumer has to pay only for the net amount of electricity that was consumed. If the solar electricity production exceeds the electricity consumption of the premises, the balance amount can be carried forward for future use for up to 10 years but no fee will be paid for the excess electricity produced.

Under the Net Accounting scheme, if the electricity generation of solar rooftop system is greater than the consumption, the consumer will be paid for the excess at the rate of Rs.22 for 1 Kwh initially. If the consumption is greater than the generation, the consumer shall pay for the excess consumption according to the existing electricity tariff structure.

The total electricity generation from the solar rooftop system would be purchased under the third category, Micro Solar Power Producer. The bill for electricity consumption would be paid to the utility as usual.The solar drive is not, however, without concerns. Although prices of solar panels have come down, considerable capital is still needed to install solar panels, so mostly it is the richer houses that can afford it.

Former CEB General Manager Shavindranath Fernando said solar power generation takes place during the daytime and the excess generation is fed back into the Grid, when the cost of the power generation is relatively low. However the same consumer will draw power from the Grid in the night when most electricity is used. Further it is at night where the Power systems are getting stressed, and the same unit of electricity will cost more to generate at night. He suggested a time-of-day tariff to buy back electricity for the national grid from solar power producers.
