Nature and Wildlife

Sri Lanka, situated at the southern tip of the Indian subcontinent is an island with an expanse of 65,610 sq km comprising of a diversified natural and cultural heritage. Sri Lanka’s terrain comprises of the coastal plains which ring the island with endless sandy beaches and an intermediate plain followed by mountain ranges situated in the center of the island; with the tropical climate of the island contributing to diversified climatic zones, primarily the Wet zone, Dry zone, and a semi-arid zone. From the hilly center of the island cascade numerous rivers to all direction of the country aiding in the island’s biodiversity setting. Due to this geographic diversity a variety of vegetation could be seen; from mangroves and marshes of the coastal plain to grasslands, dry mixed evergreen forests and tropical rain forests of the intermediate plain to montane forests of the hill country. For the protection of the diverse flora and fauna found within these habitats there are over 60 wildlife reserves and conservation forests divided into various categories such as National Parks, Nature Reserves, Strict Nature Reserves, and Sanctuaries covering all climatic regions and vegetation types in the country. These are maintained by the Department of Wildlife Conservation and the Forest Department of Sri Lanka.
Although being an island which was last connected to the mainland India over 7000 years ago, Sri Lanka’s wildlife comprises of a rich species diversity with 125+ mammal species including the world’s largest the Blue Whale, The Sri Lankan Elephant, and the Sri Lankan Leopard. Sri Lanka also boasts a rich species diversity of 119 amphibian out of which 103 are endemic making the country the highest amphibian endemism in Asia, and also over 190 species of reptiles including Crocodiles, Snakes, Lizards, Turtles and Tortoises with 52% of the species being endemic. There are recorded 165 freshwater fish species in the country found in the endless rivers, streams and lakes; and the largest numbers of species of an animal class found in Sri Lanka are Birds, with 500 resident and migrant species including 33 endemics. Together with over 3500 species of plants and trees Sri Lanka adds up to a rich biodiversity adding flavor to its already colourful cultural heritage. With a population of about 20 million people in the island the loss of forest cover in the last century due to the expanding population has resulted in a serious threat to natural habitats with many species being regarded endangered. As a result the entire island of Sri Lanka along with the Western Gharts of India makes one of the 35 Biodiversity Hotspots in the world.

National Parks

The category of National Parks gives complete protection to wildlife while giving access to the public to enjoy wildlife in its natural habitat as well as for research purposes. Under the Flora and Fauna Protection Ordinance of 1937 as at 2015 there are 26 designated regions as National Parks providing complete sanctuary for wildlife. These Parks are maintained by the Department of Wildlife Conservation of the Government of Sri Lanka and could be accessed at the designated entrances by purchasing tickets.

Among the wildlife attractions of the island, the safari rides of the National Parks takes first place with the largest and most famous being the Yala National Park and Wilpattu National Park. Although the majority of the National Parks are found in the dry zone, the Parks of Horagolla, Galwaysland and Horton Plains are found in the wet zone with the latter two being situated in the central hills.

Wetlands

Wetlands can be defined simply according to the National Wetland Directory as habitats with permanent or temporary accumulation of water with associated floral and faunal communities, such as rivers, marshes, lagoons, salterns etc. Wetlands comprise of its own unique ecosystem and hence are important habitats of the fauna and flora of the country. The importance of the conservation of the world’s wetlands which accounts for 6% of the world’s landmass was understood by the international community which culminated in the RAMSAR Convention of 1971 held in Iran, according to the convention wetlands are:

“Areas of marsh, fen, peat land or water, whether natural or artificial, permanent or temporary with water that is static or flowing, fresh, brackish or salt, including areas of marine water the depth of which at low tide does not exceed six metres.”

In Sri Lanka 14% of the land accounts for wetlands with the majority of the areas being in the coastal region. According to the RAMSAR definition, Sri Lanka’s wetlands can be divided as:

1. Inland natural fresh water wetlands (e.g. rivers, stream, marshes, swamp forests andvillus)

2. Marine and salt water wetlands (e.g. lagoons, estuaries, mangroves, sea grass beds, and coral reefs)

3. Man-made wetlands (e.g. tanks, reservoirs, rice fields and salterns)

Out of the 22 types of wetlands described by RAMSAR, there are 6 main wetlands found in the country, they are:

1. Bundala wetlands

2. Anawilundawa wetlands

3. Madu ganga wetlands

4. Wilpattu wetlands

5. Kumana wetlands

6. Wankalei wetlands

Natural World Heritage Sites

Sri Lanka is blessed with 8 UNESCO World Heritage Sites making the country the third highest country in terms of density of WHS behind China and Italy. Out of the 8 sites, two fall under the category of Natural WHS.

1. The Sinharaja Virgin Rainforest

2. Central Highlands

The Sinharaja Rainforest comprises of one forest reserve whereas the Central Highlands can be divided into the Knuckles Conservation Forest, Peak Wilderness Nature Reserve, Morahela Conservation Forest, Walawe Basin Conservation Forest, Sri Pada Conservation Forest and the Horton Plains National Park. The Department of Wildlife Conservation maintains the Horton Plains National Park and the Peak Wilderness Nature Reserve while the rest of the reserves above are maintained by the Forest Department.

Sinharaja Rainforest

The virgin rainforest of Sinharaja is situated on the borders of the Western, Sabaragamuwa and Southern Provinces and is one of the last virgin rainforests in the country being in par with the rainforests of the Amazon and the Congo in terms of its rich biodiversity. It accounts for 11,885 hectares and was listed as a Biosphere Reserve in April 1978 and 8,864 hectares of it was listed as a World Heritage Site in 1988 being Sri Lanka’s first Natural World Heritage Site. The name Sinharaja means ‘Lion Kingdom’ which according to folklore was the home of a Lion.

Sinharaja can be accessed from 3 places, the Colombo-Ratnapura-Kalawana road, Colombo-Rakwana-Morning side road, and the Colombo-Deniyaya-Mederipitiya road. Nature trails have been set within the forest for tourists to hike with relative safety but require and guide to accompany. The trails are:

Situated on a hilly terrain in the Sabaragamuwa mountain range its vegetation is made up of tropical lowland wet evergreen forests including sub montane forests and grasslands. It receives rainfall throughout the year with an annual rainfall of 2500-5000mm with temperatures ranging from 20C – 30C. The diverse terrain includes valleys, ridges, and rocky hills with the Sinhagala being the highest peak. Its wet tropical climate has made this a hub of freshwater habitats and a number of springs and streams originate from here which feed two of the main rivers in the country, the Kalu Ganga and the Gin Ganga. Further adding to the forest’s water heritage are the many beautiful waterfalls such as the Duli falls, Hathmale falls, Brahmana falls, and the Nelugolla falls. The floral diversity of the rainforest comprises of 337 species of woody plants out of which 192 are endemic with 16 species considered very rare. There are identified 30 locally threatened species and 116 globally threatened species. Sinharaja is known as the forest with the highest diversity of woody plants in the island.

The wildlife of the forest records over 140 families of species and includes 44 mammals such as the elusive Leopard, Elephant, Wild Boar, Sambhur, Barking Deer, Mouse Deer, the endemic Purple faced leaf monkey, and the Golden palm civet etc. It further holds 71 species of reptiles, 33 species of amphibians, 19 species of fish and 147 species of birds which all 33 endemic species found within the rainforest.

Knuckles Conservation Forest

ImageThe Knuckles conservation forest comprises of the Knuckles mountain range situated north in the central highlands plateau of the country which falls under the Matale and Kandy Districts of the Central Province. The range comprises of the 5 peaks of Kirigalpoththa, Gombaniya, Knuckles, Koboneelagala and Dotulugala with surroundings peaks such as Kirimatikanda, Kalupahana, and Lakegala. The Dumbara hills as knuckles is known in Sinhala meaning misty mountains was first declared a reserve in 1873 and a conservation forest in April 2000. In 2010 it along with the Horton Plains and Peak wilderness was named the Central Highlands World Heritage Site.

The Knuckles mountain range has many trails and several motorable access routes are found from Kandy and Matale.

The drastic topography of the forest gives it a wide range of climatic and vegetation features, from wet regions of 5000mm annual rainfall to nearly arid forests of less than 2500mm of rainfall. The vegetation could be seen as semi-evergreen at the foothills and valleys and upper montane rainforests in the upper regions and summits. The region is also an important watershed with many springs and streams feeding the Mahaweli River such as the Heen Ganga, Maha Oya, Theligamu Oya, and the Hulu Ganga. This diverse vegetation Imagehas created unique ecosystems with an abundance of flora and fauna with some species being point-endemic. Its uniqueness is still being discovered with recent researches showing 115 plant species out of 148 species found in the Moraella region in Knuckles being found in the tropical rainforest of Sinharaja, thus making a mini Sinharaja within Knuckles. Other forest types occurring here are dry sub-montane forests, riverine forests, shrub lands, pathana grasslands as well as pigmy forests. The forest contains a total of 228 woody plant species with 15% of them being endemic and as well as 1033 flowering plant species.

The fauna of Knuckles consists of 31 species of mammals such as the Elephant, Wild boar, Jackal, Mouse deer, Sambhur, Loris, Macaque, Leaf Monkey etc. Further 53 reptile species, 20 amphibians, 128 birds, 60 butterflies and 15 freshwater fish species are recorded from here. Out of the many endemic species found here, Kirthisinghe’s Rock frog and the Leaf nose lizard are only found in the Knuckles range making them point-endemic species.

The Knuckles range is an important and famous tourist destination with many wildlife and natural attractions and is a haven for hikers. Some of the region’s attractions are Lakegala, Riverstone, Mini worlds end, Dothalugala, Nitro cave, Corbett’s gap, Pitawala Patana and the waterfalls of Bambara Ella, and Duvili Ella.

Wildlife

Being a small island with a growing population of 20 million people Sri Lanka boasts a remarkable diversity of flora and fauna species with a high degree of endemism including species both plants and animals with point-endemism. The tropical climate with the island’s drastic topography has created a variety of diverse ecosystems with ranging climatic conditions allowing one to observe a variety of wildlife from the coral reefs below sea level to life 2000 meters above sea level.

Sri Lanka’s mammals include the main big-four, the Blue Whale, the Sri Lanka Elephant, the Sri Lanka Leopard and the Sloth Bear. Whales could be spotted within few kilometers off the coast with some of the highest concentration in the south of the island. Sri Lanka also holds one of the highest densities of Elephants in the world with a recorded population of around 5000 individuals; the majority of them living within protected wildlife reserves while some herds can be found off reserves as well.

Other notable mammals of Sri Lanka found within the reserves are the Water Buffalo, the Wild Boar, Sambhur, several species of Deer, several species of small cats such as the Fishing Cat and the Jungle Cat, the Jackal, the Porcupine, three species of primates and as well as the elusive Slender Loris. Much of these mammals could be spotted off reserves in small pockets of forests and villages throughout the island. Due to loss of habitat, dozens of species of mammals including prominent species such as the Leopard are under threat from extinction.

Sri Lanka boasts high species diversity in amphibians mainly comprising of frogs with one of the highest endemism rates in the world. Mainly found within the wet zone of the country more than 50 species are threatened with extinction due to habitat loss while some have been reported as extinct, yet every now and then new species of frogs are being discovered in the island revealing its remarkable yet-untapped natural heritage.

Reptiles comprises yet another interesting category in Sri Lanka’s wildlife with over 190 species comprising of 2 species of Crocodiles, 8 species of Turtles, 1 species of Tortoise, several species of Lizards including two large Monitors and over 100 species of Snakes. Out of the snakes only 6 land species are found to be deadly venomous – the Indian Cobra, the Sri Lankan Krait, the Indian Krait, the Russell’s Viper, the Saw-scaled Viper and the Sri Lankan Coral snake. A variety of brightly coloured lizards too could be found including the endemic and unique Horned Lizard.

The avifauna of Sri Lanka amounts to an astounding 500 species of birds, both resident and migratory with 33 species being endemic. Further attractions of Sri Lanka’s wildlife are the 165 species of recorded Freshwater Fish, the over 200 species of Butterflies and over 100 species of Dragonflies and other insects and also an astounding 51 species of Freshwater Crabs with all being endemic to the island.

The Sri Lanka Elephant (Elephas maximus maximus)

ImageThe Sri Lankan Elephant is one of the three subspecies of the Asian Elephant, one of the largest land mammals on earth. This subspecies found only in the island is the largest and the darkest amoung the Asian Elephants. The Sri Lankan Elephant is currently listed as endangered by the IUCN and has seen a reduction of its population by half; this being due to hunting during the colonial period and habitat loss in the 20th century. The Elephant is also symbolic to the culture of the island having being associated with the history of the Sinhalese civilization from early on. The elephants were used for domestic work such as transportation and construction in the ancient days as well as for war, with many accounts in the chronicles such as the famed Elephant named ‘Kandula’ of the 1st century BC Sinhalese hero King Dutugamunu as well as 16th century Portuguese accounts which state that the Sinhalese King Rajasinghe I had 2200 elephants in his army when attacking the fort of Colombo in 1587. The Elephant is also seen as a symbol of strength and majesty and is used to carry the casket of the Tooth relic of the Buddha in the annual Esala Perehara of Kandy.

The average height of an adult male is 2.5 meters at the shoulder with the female slightly smaller than the male. Tusks are only found in few males and very rarely found in females. They weigh between 2000-5000 kg and can live up to 60 years. The gestation period of the elephant is one of the longest which lasts 22-23 months and usually one calf is born. The elephants being social animals live in herds of up to 12-20 animals and are headed by the oldest female. Males leave the herd as they reach adolescence and tend to live solitarily but are not far from the herd. They feed on the vegetation around them amounting to 275-300kgs a day. They feed during the early morning and late afternoon. They drink two to three times a day and being great swimmers they enjoy their time in the waterholes.

The Sri Lankan Elephant once roamed the entire island but now is confined to the Dry zone with a very small number inhabiting the Peak Wilderness Sanctuary around the vicinity of Adams Peak. Although protected areas such as the large National Parks in the dry zone give shelter to elephants, around 65% still roam outside protected areas. This has led to an escalating Human-Elephant conflict in recent times. As per a census in 2011, Sri Lanka’s elephant population was numbered at 5,879 individuals.

The Sri Lanka Leopard (Panthera pardus kotiya)
Image

The Leopard is the largest big cat in the country and is the apex predator in the island, it also regarded as a keystone species in determining the densities and numbers of prey species in its respective ecosystems. The Sri Lankan Leopard is a subspecies of leopard endemic to the island. It has been listed as endangered due to poaching and habitat loss. It is estimated that there are around 750-1000 individuals throughout the country. Leopards are found throughout the dry zone and wet zone and even in the central hills living within protected areas as well as isolated forest patches.

An adult male can reach a length of 2 meters with the female being shorter. This subspecies is considered larger than other species of leopards in the world. The gestation period lasts for 13 weeks with 2-3 cubs being born. The leopard is a solitary hunter and its prey includes Sambur, Deer, Hare, Langurs, birds and reptiles.

The leopards living outside protected areas generally avoid humans and hardly any attacks have been reported in the island, however it is known to kill domestic animals and livestock and such incidents have led to the setting of traps resulting in the deaths of many leopards. It is also illegally poached for its skin and hence its inclusion as an endangered species. The leopard is a frequent attraction in the dry zone National Parks of the country with the Yala National Park boasting the highest density of leopards in a National Park in the world.

The Sri Lankan Sloth Bear (Melursus ursinus inornatus)
Image

The Sloth bear is a species of omnivorous bear found in the countries of Nepal, Bhutan, India and Sri Lanka with the Sri Lankan Sloth Bear being a subspecies endemic to the island. It is found throughout the dry zone in forested areas. The sloth bear is listed as Vulnerable globally and highly threatened nationally due to loss of habitat and poaching. It is reported that less than 500 animals survive in the wild.

This shy animal is mostly nocturnal and feeds during the early hours of the morning. It is a solitary animal but are also found in pairs. They feed predominantly on ants and termites and also feed on a variety of fruits such as Palu and Weera. The average height of an adult male is around 90 cm and females are around 60 cm. They can weigh from 120-310 lbs. The gestation period lasts for 7 months with usually 2 cubs being born. The young remain with their mother for around 2-3 years until fully grown. They have been known to live up to 21 years and are very dangerous when confronted.

The Sri Lankan Sambhur (Rusa unicolour unicolour)

The Sambhur is the largest deer found in the island and inhabit the dry zone forests as well as the mountains. It is the most common mammal seen in the Horton Plains National Park in the Central highlands.

The males are larger than the females rising about 1.3 meters at the shoulder. Antlers are found only in the males which grow to about 68 cm. These nocturnal deer prefer the forests and feed on leaves, grass and fruits. These animals are generally solitary creatures but small groups of females with young are seen such as in Horton Plains. They are known to live up to 10 years in captivity. Their gestation period is about 8 months with normally one fawn being born.

Crocodile
Image

Sri Lanka is home to two species of crocodile, the Mugger Crocodile and the Saltwater Crocodile. The Mugger Crocodile (Crocodylus palustris kimbula) also known as the Swamp crocodile is greenish olive in colour with dark markings and it can grow up to 4 meters in length with females being smaller than the males. The female lays its eggs in about a half a meter deep hole generally on the sandy banks of rivers and lays about 30 eggs; the incubation period is around 60 days. The Mugger is found along the water ways of rivers, streams and tanks of the low country dry zone and is generally found in large groups.

The Saltwater Crocodile (Crocodylus porosus meniyanna) also known as the Estuarine crocodile is olive brown in colour and can reach lengths up to 5.5 meters. The female lays her eggs in a mound built of organic matter along the water’s edge with the number of eggs laid and incubation period same as that of the Mugger. The Saltwater crocodiles are confined to the coastal areas in environments such as coastal mangroves, swamps, lagoons and estuaries of large rivers. The Saltwater crocodile is generally solitary and is a known man-eater.

The Mugger and the Estuarine crocodiles are at the top of the food chain in their respective ecosystems and they generally feed on crabs, fish, frogs, terrapins, lizards and mammals as well. They spend much of the day basking in the sun on the banks of rivers and lakes. Their habitation of the rivers and streams has brought them into close contact with humans and has resulted in the dead of many humans; this struggle is known as the Human-Crocodile conflict.

The Toque Macaque (Macaca sinica)
Image

This is a species of Monkey endemic to the island is the most commonly found species of monkey. The Macaques are found throughout the island from the low country dry zone to the central hills. Three subspecies of this monkey has been identified based on different climatic and geographic regions. The Dry zone Toque Macaque (Macaca sinica sinica) can be found throughout the dry zone of the country, the Wet zone Toque Macaque (Macaca sinica aurifrons), found in the wet zone and the central hills and the Highland Toque Macaque (Macaca sinica opisthomelas) which is found in the montane forests around Horton Plains.

All three species share the same physical characteristics but differentiating in colour and hair on their cap. The males are larger than the females and an adult male could be around 52cm in length with the female being about 41cm. The males can weigh between 4 - 5.5kg and the females at 2.5 – 4.5kg. They live in troops of about 20 individuals and although they are expert climbers, they tend to move about for most of the time on the ground. Their food consists of leaves, fruits, flowers, seeds, and occasionally lizards, insects and birds. They also store food in their cheek pockets to be chewed later. The Toque Macaques are known to live for 20-30 years in captivity. Their gestation period is usually 6 months and normally gives birth to one and rarely two young.

Although this species’ population is declining, it is yet to be given national protection despite it being an endemic species, mostly due to the fact that it is considered a pest attacking crops and home gardens in semi urban areas.

Giant Squirrel (Ratufa macroura)

The Giant Squirrel also known as the Grizzled Squirrel is a large tree dwelling squirrel native to South India and Sri Lanka. Found throughout the island there are three subspecies of the Giant squirrel.

The Highland Giant Squirrel or the Long-tailed Giant squirrel (Ratufa macroura macroura) is found in the Central and Uva hills. Its upper body is black in colour with the under part pale. This is the largest amoung the subspecies found in the island and has an overall length of about 82cm. The female is slightly larger than the male.

The Black and Yellow Giant Squirrel (Ratufa macroura melanochra) is found in the rainforests of the wet zone. This species is similar in colouring to the Highland species and is slightly smaller than the Highland species with an overall length of around 78cm.

The Lowland Giant Squirrel or the Common Giant Squirrel (Ratufa macroura dandolena) is found in the low country dry zone and is grey in colour and smaller than the other two measuring in length of around 70cm.

These are diurnal animals and spend most of their time in the trees, coming down to the ground only to chase off and intruder or during breeding. They are usually found in pairs and are active during the early hours of the morning and the late afternoons. They feed on leaves, bark, fruits, berries etc. They are highly territorial and built 4-5 nests within their territory in the trees.

Whales and Dolphins

Being an island situated in the Indian Ocean close to the equator, its tropical waters are home to diverse variety of marine life. Chief amoung the marine life are the whales and dolphins. Sri Lanka is only now coming to explore its seas having being restricted due to the island’s 30 year civil war which ended in 2009. It is now beginning to develop as a hotspot for whale and dolphin watching as out of the 80 species of whales in the world, around 26 species has been spotted around the waters of Sri Lanka; amoung them the largest animal on the planet, the Blue Whale.

Some of the other whales seen around Sri Lanka are the Humpback Whale, Fin Whale, Killer Whale, Minke Whale, Sperm Whale, Pygmy Sperm Whale, Dwarf Sperm Whale, Bryde’s Whale, Melon Headed Whale, Southern Bottlenose Whale, and the Short-finned Pilot Whale.

Most of the whales are seen during their migration from the Arabian sea to the Bay of Bengal but a colony of Blue Whales are thought to be permanent residents in the waters around the south of Sri Lanka due to the narrow continental shelf. Whale sightings are famous off the coast of Kalpitiya in the west, off the coast of Mirissa in the south and off Trincomallee in the east.

A variety of Dolphins too are found around the waters of Sri Lanka such as the Bottlenose Dolphin, Spinner Dolphin, Fraser’s Dolphin, and the Spotted Dolphin. Kalpitiya in the western coast is a famous location for Dolphin spotting.

Marine biologists are only now studying this massive treasure trove of wildlife and believe they could be in danger due to the whales’ routes being across one of the busiest maritime shipping routes in the world, from the Arabian Sea around the southern tip of the island to Singapore in the east. They believe that the rapid expansion of tourism in whale watching in recent years too could have a negative impact on the habitat of the whales and dolphins.
