4 Nights in a DZ Sri Lankan forest reserve

Location: Galgirikanda area, nearest town, Galgamuwa.  Elevation ~ 200m.  Temperature 30-33 C.  Moderately humid, so unpleasant unlike in more arid conditions during the time of visit in early August 2017.  This is a flat area interspersed with rocks and hills up to a height of 700m.  Up on the rocks, the views are stunning in the morning and evening (see @Lanka_Wildlife for pics) and quite pleasant with cooling, sometimes strong winds, especially by evening moonlight, illuminating the landscape devoid of obvious man-made structures while I was there, as far as the eye could see.
Though mostly dry, there is enough rain to maintain verdure and feed wells, rocky hollows and puddles frequented by birds to bathe and drink in the evenings in particular.  The water is somewhat mineralised (“kivul”) leaving ones hair somewhat stiff and tangled.
The botany is dominated by indigenous plants (unlike the wet zone) including giant Euphorbia cacti, Toddy (Thal) palms (Borassus flabellifer) and dozens of species of tree such as Ebony, “Cone” (? with fruits similar to gal siyambala), Palu, Wood apple, “Timbiri” and Margosa (Neem) trees among others with the understory often dominated by curry leaf plants.  Indigenous Iluk "pitiyas" or plains still carry on, though these may be drowned by invasive mana in future.
The dust is hollowed by the pits of ant-lions.  The leaf litter crawls with orange insects like weevils (pictured).  There are long trains of black termites, colonies of larger biting ants that can weal the skin and leaf stitching red ants that fall from trees.  The dry zone cicada is especially active and infernal as the temperature rises in the afternoon.  Of butterflies there are quite a few including the slow flapping common rose (Papilio polytes).
The signature bird by day is the Indian Shama that sings beautifully at most times, loudest by dawn and dusk.  Several Shamas seem to compete in song around circles of 100-200 feet or so unless the same individual keeps moving around.  I asked a local resident who happened to be Danish whether the Magpie robin or the Shama was the better singer.  He replied that the Shama was the “Chopin” among bird singers, though you’d have room to disagree as he also enjoyed the song of the Indian nightjar (that kept him company by night).  Post sunset it’s the turn of Jerdon’s nightjar, repetitive but quite pleasant.  These birds seem to reply to calls from rivals within hearing range.  There are many other birds such as peacocks, jungle-fowl, black-capped bulbuls, brown-capped babblers and pompadour pigeons leaving aside commoner species (the Indian ring dove, all Sri Lanka barbets except the Yellow-fronted) and those unidentified.  The birds may be zoned as agricultural (ring dove, yellow billed babblers) living outside of the forest and forest birds themselves like the Shama.  Others such as Brahminy Kites, seem to occupy both habitats, especially associated with water.
The signature mammals include elephant (supressed by miles of electrocuted fencing), axis and mouse deer, jackals, macaques, porcupines, hare, giant squirrel and the loris.  Amongst those most easily encountered in the dark were hare, loris and mouse deer as well as either a toddy cat or dry zone golden palm civet up a tree.  The mostly invisible elephants seem to voice their despair by night, screaming like the chained giants they are devoid of the freedom to roam at their pleasure.  Their routes are blocked and at the time of the writing the government fails to provide them with elephant corridors to link up forest reserves.
Reptiles are more obvious and active in the dry zone than in the wet.  Skinks are very common in the leaf-litter as they rustle the ground in the search for prey, constantly chasing off fellow rivals.  Even the tallest trees can be climbed by the large land monitors and when descending they come down vertical trunks with the head down (upside down) like squirrels, suggesting that their rear limbs have phenomenal holding power for such a large and seemingly unwieldy lizard.  It’s quite confiding as long as one keeps a distance and can allow the cameraman almost near its face (at least the one I was looking at did).  I saw a painted lips agama, Calotes ceylonensis busily dashing down a tree with the head and chest area a stark black and white.  Then it noticed me and stood still, starring back, slowly turning a bright orange to replace the former white.  It carried on observing me for quite a while and it was I who had to give up.
There are miles of low trees in areas subjected to former chena cultivation but towards the rocks and hills unsuitable for cultivation, massive older trees carry on including forests of ironwood that may have been planted two thousand years ago.  In the crevices of these rocks, large enough for animals hides the mouse deer that may remain all day, observing people as they pass by.  You can detect them at dusk by torchlight.  The dry zone loris looks like it’s peddling a bicycle on all fours as it creeps around branches, both in the treetops and at knee level in bushes.  Its eyes dance like a pair of candle flames by torchlight from a tree or bush, but the mysterious animal is rather elusive and can disappear while you try and get camera ready.
The cone trees (whatever that species may be) drops hundreds of small brown fruits with seeds the size of a peanut.  Apparently the fruits were consumed by children but no more.  Similarly, the toddy palm leaves used to make the best roofing, especially if applied in several layers, but once again not used much any more.  I really looked forwards to constant showers to keep me sane, using a local Margosa (Kohomba) soap.  The evenings were the best times to chat with others on the rocks or in their little cottages, sipping tea to discuss politics, the weather and wildlife.

Outside forest reserves the land is cut up and bulldozed apace and the illusion of a sea of forest along with plains of soft native Iluk grass (pictured) quickly gives way to “progress”.

Paradise Lost To Plastic Waste

Reproduced from Sunday Times Sri Lanka, Plus, Sunday Dec 4 2016

People are naturally messy like other social animals – monkeys and bats leave piles of debris under fruiting trees following feeding frenzies. Until recently, any litter we left after a picnic was rendered to almost nothing by microbes, fungi and other natural agents. Humanity produces more “waste” than all wild animals put together but it’s only in the last 70 years that this is producing an indelible stain worse than ugly. Two major streams of waste now threaten the Sri Lankan environment: sewage and plastic. Sewage is another story but what of the non-biodegradable plastic, produced from foreign oil? Over 90% of this is tragically single use disposable packaging or consumables like bottles, straws, cups and polystyrene. Mostly not recycled, a great deal ends up in the oceans. The trouble is that plastic, unlike organic waste is persistent, chemically stable from hundreds to thousands of years and generally only breaks down into particles that enter food webs eventually returning to contaminate our bodies.

Since 1974 global plastic production has rocketed by over 620%. Broadcaster David Attenborough thinks that the 8 million tonnes of plastic annually dumped in the seas is worse than sewage. There are five vast accumulations of ocean plastic of which the north Pacific “gyre” represents the largest, a stew of plastic at least 800,000km2 in extent. According to a report in Science, 2015, about 30% of this is from China topping a list of five countries responsible for over 60% of ocean plastic, followed by Indonesia, the Philippines Vietnam, and Sri Lanka with a poor waste infrastructure (PWI). In a more recent analysis the top five countries include Thailand making Sri Lanka the sixth largest polluter. How does a tiny Indian Ocean island exceed larger competitors as a garbage champion? 

Remember the advent of the “siri-siri” bag in Sri Lanka from the 1980s, a noisy novelty? In South Africa, trees covered in plastic bags earned them the sobriquet “the national flower” now applicable to our island. Before them provisions were wrapped in newspaper cones tied with jute or coconut string with meat and fish in waterproof taro leaves before carriage in rattan baskets. Remember banana rice packets, wrapped palm leaf or refillable glass bottles, waxed paper and clay pot containers? Somehow, we managed like this for millennia.

Today, we are force fed plastic bags. Some restaurants cover plates with plastic to avoid washing them. Everything is encased in this ubiquitous substance. We only consider contents rather than the wrapping but it’s the packaging that now haunts us in ways more sinister than appearances.

Discarded plastic nets and lines kill vast amounts of marine life in a process described as ghost fishing. Thousands of turtles die as a result of ingesting plastic bags that they mistake for jellyfish; whales are also affected. A third of the chicks of Laysan albatrosses die as their parents feed them plastic of a dwindling population of 1.5million. Meanwhile, sewage treatment plants struggle to deal with plastic microbeads used as an abrasive exofoliant in toiletries that readily pollutes waterways – already there are more plastic particles in the Danube than fish fry and it is predicted that oceanic plastic will outnumber fish by 2050.

In Sri Lanka the evils of plastic are increasingly evident. They cause floods such as those that inundated Colombo 7 not too long ago by blocking drains and sewers during heavy rain. They kill grazing animals among others after blocking their stomachs and help destroy life in aquatic habitats. They form horrible, unsightly piles on roads, in streams and even on the outskirts of forests and litter paths used by people. They empower mosquitos and diseases like dengue. Forming the bulk of persistent, solid waste, they take up untold space in wilderness such as landfills on the fringes of Wilpattu National Park, land all too precious in the confines of the island. The authorities in Gampola were dumping such waste on the top of Ambuluwawa hill, before it tumbled down overwhelming small farms and polluting local rain-fed streams into rivers including the Mahaweli. We are now unwittingly consuming plastic, with all the associated chemicals such as flame-retardants and pthalates through packaging and via seafood that has accumulated plastic debris. There is increasing evidence that the chemicals in plastic entering our bodies cause cancer, infertility and birth defects. Last but not least, Sri Lanka is offloading its plastic load into the surrounding oceans affecting the whole world. But plastic is still seen as fashionable and powerful packaging businesses will fiercely oppose government plans to moderate the menace.

The most important solution is to reduce consumption of single use disposable plastic as highlighted in a recent report by the World Economic Forum by scientists and business - we as consumers have a role. In Sweden, waste to energy plants produce 20% of the heating in populated districts and 99% of waste is either recycled or incinerated so efficiently that they need to import 800,000 tonnes of waste from outside. “Sweden runs out of garbage” read a recent headline. US Company Ecovative is producing a lightweight polystyrene alternative Mycofoam from fungi now championed by Ikea; Japanese researchers are developing algal agar plastic and compostable cornstarch bioplastic is increasingly popular. A brewery in the US has just developed edible six-pack rings for holding beer cans. Whereas natural packaging: egg shells and banana peel are hard to replicate, there is demand for such innovation. England only banned free plastic bags last October (usage has already plummeted by a staggering 80%), China got there in 2008. New York and Washington DC have initiated bans of Styrofoam and there will be a partial US ban of microbeads by 2017. In March 2016, the government of Karnataka, India banned plastic production and use: “No shopkeeper, … hawker or salesman shall use plastic carry bags, plastic banners, plastic buntings, flex, plastic flags, plastic plates, … cups, … spoons, cling films and plastic sheets for spreading on dining table irrespective of thickness … and … micro beeds (sic).” Meanwhile, our government is struggling to implement its 2007 ban on plastic sheeting thinner than 20 microns.

With well-developed waste practices in Scandinavia, Taiwan and increasingly the US, Sri Lanka remains a model of PWI. The plastic on paradise is piling up and flowing via streams, sewers and rivers into the sea almost exponentially. In village roadsides, women carry on sweeping up the “national flowers” and packaging creating unsightly, dangerous fires in a country that once boasted more imaginative solutions.

It will be a while before our “statesmen” take serious action. Private enterprise may have to take a lead – fashion conscious individuals are sporting “I’m not a plastic bag” cloth-bags, emblazoned with promotional logos to advertise brands or services. People will happily pay more for eating from banana or lotus leaves. At Adam’s peak and Horton Plains, brave officials have banned plastic bags. Perhaps we can start small by at least separating out our waste between biodegradable food waste, recyclables such as glass and cans and non-biodegradable plastics so that they can be processed differently as is happening at a few civilised venues. Food waste can be composted, fed to animals or turned into biogas. Glass, paper and even some plastics can be recycled. There has been a thriving “bothal-pattare” recycling scene for quite a while and I for one celebrate the biodegradable recycled paper bags made from school exercise books with examples of maths or English homework, out of which I consume peanuts in busses. There could be incineration plants in the future that can burn some of our wastes to produce electricity. Our government needs to ban or tax free single use disposable plastic and incentivise biodegradable solutions like our predecessors did with their smarter botanical solutions a great deal more. As in Singapore, the casual disposal of litter should be fined. Canadian environmentalist professor David T. Suzuki has said “Garbage is a state of mind”. Garbage could be profitable based on recycling, animal feed, organic fertiliser, biogas and waste to energy incineration.

We should all endeavour to cut back on plastic use by encouraging solutions such as refillable bottles, the greater use of metal, cellulose, biomaterials and voicing our concerns to shops and companies. Businesses and shops with a zero waste emphasis are appearing in the developed world and we can all divest, by degrees in plastic. I’m saving money by buying less plastic, making my own shampoo and cleaners – internet searching makes the refinement of environmental choices easier. With a little technology, we can now even charge phones by burning domestic waste. Keep saying no to single use disposable plastic – they’re bad for our bodies and wildlife. Say hello to recycled paper packaging, paper straws (they do exist), rattan baskets, plant leaf wraps tied in organic string. Such timeless packaging is today increasingly fashionable around the world, better for our health and the planet.
