Sri Lankan elephant


The Sri Lankan elephant (Elephas maximus maximus) is one of three recognized subspecies of the Asian elephant, and native to Sri Lanka. Since 1986, Elephas maximus has been listed as endangered by IUCN as the population has declined by at least 50% over the last three generations, estimated to be 60–75 years. The species is pre-eminently threatened by habitat loss, degradation and fragmentation.[1]
Elephas maximus maximus is the type subspecies of the Asian elephant, first described by Carl Linnaeus under the binominal Elephas maximus in 1758.[2]
The Sri Lankan elephant population is now largely restricted to a few National Parks and Nature Reserves. Udawalawe National Park,Yala National ParkWilpattu National Park and Minneriya National Park are prime locations for spotting elephants.

Characteristics[edit]

In general, Asian elephants are smaller than African elephants and have the highest body point on the head. The tip of their trunk has one finger-like process. Their back is convex or level. Females are usually smaller than males, and have short or no tusks.[3]
Sri Lankan elephants are the largest subspecies reaching a shoulder height of between 2 and 3.5 m (6.6 and 11.5 ft), weigh between 2,000 and 5,500 kg (4,400 and 12,000 lb), and have 19 pairs of ribs. Their skin color is darker than of indicus and of sumatranus with larger and more distinct patches of depigmentation on ears, face, trunk and belly.[4]
Only 7% of males bear tusks.[5] However, according to the elephant census conducted in 2011 by the Wildlife Conservation Department of Sri Lanka, only 2% of the total population are tuskers.
The elephant population in the National Parks of Sri Lanka is somewhat diminutive in stature when compared both with historical accounts dating back to 200 BC and with the early photographs taken in 19th century during the time of colonial British rule of the island. The smaller size could possibly be the end result of a long-continued process of removing the physically best specimens from the potential breeding-stock through hunting or domestication (see insular dwarfism).

Distribution and habitat[edit]

Elephants are restricted mostly to the lowlands in the dry zone where they are still fairly widespread in north, south, east, north-western, north-central and south-eastern Sri Lanka. With the exception of a small remnant population in the Peak Wilderness Sanctuary elephants are restricted mostly to the lowland in the dry zone but are absent from the wet zone of the country. With the exception of Wilpattu andRuhuna National Parks, all other protected areas are less than 1,000 km2 (390 sq mi) in extent. Many areas are less than 50 km2(19 sq mi), and hence not large enough to accommodate the entire home ranges of elephants that use them. In the MahaweliDevelopment Area, protected areas such as Wasgomuwa National ParkFlood Plains National ParkSomawathiya National Park, andTrikonamadu Nature Reserve have been linked resulting in an overall area of 1,172 km2 (453 sq mi) of contiguous habitat for elephants. Nevertheless, about 65% of the elephants range extends outside protected areas.[6]

Ecology and behaviour[edit]

Elephants are classified as megaherbivores and consume up to 150 kg (330 lb) of plant matter per day. As generalists they feed on a wide variety of food plants. In Sri Lanka's northwestern region, feeding behaviour of elephants was observed during the period of January 1998 to December 1999. The elephants fed on a total of 116 plant species belonging to 35 families including 27 species of cultivated plants. More than half of the plants were non tree species, i.e. shrubherbgrass, or climbers. More than 25% of the plant species belonged to the family Leguminosae, and 19% of the plant species belonged to the family of true grasses. The presence of cultivated plants in dung does not result solely due to raiding of crops as it was observed that elephants feed on leftover crop plants in fallow chenas. Juvenile elephants tend to feed predominantly on grass species.[7]
Food resources are abundant in regenerating forests, but at low density in mature forests. Traditional slash-and-burn agriculture creates optimum habitat for elephants through promoting successional vegetation.[6]

Population trend[edit]

In the historical past, elephants were found in the dry zone, the lowland wet zone, as well as in the cold damp forests of the mountains in the island. They enjoyed wide distribution and good numbers from sea level to the highest mountain ranges. Until 1830, elephants were so plentiful that their destruction was encouraged by the Government, and rewards were paid for any that was killed. Their disappearance from the montane zone began with the largescale clearance of forests for the planting of coffee, and afterwards tea, during the first half of the 19th century. Even by the turn of the 20th century, elephants were distributed over much of the island.[6]
Elephant populations in Sri Lanka were seriously depleted through capture and slaughter in the 19th century. Between 1829 and 1855 alone, more than 6,000 elephants were captured and shot.[8]
Size of wild elephant populations in Sri Lanka estimated at
  • 12,000 to 14,000 in the early 19th century;[citation needed]
  • 10,000 in the early 20th century;[9]
  • 7,000 to 8,000 in around 1920;[citation needed]
  • between 1,745 and 2,455 individuals in 1969;[10]
  • between 2,500 and 3,435 in 1987;[10]
  • 1,967 in June 1993 fragmented in five regions;[11]
  • between 3,150 and 4,400 in 2000;[12]
  • 3150 in 2006;[citation needed]
  • 2900-3000 in 2007.[citation needed]
  • 5879 in total, 2011 elephant census

Threats[edit]

Ivory trade in Sri Lanka had a very long history for more than 2000 years. During the Colonial rule in 19th century and early 20th century many bull elephants were killed by trophy hunters. Major Thomas Rogers is credited with having shot over 1,500 elephants. This works out to an average of one elephant being killed by him every day for four years. Two others, Captain Galleway and Major Skinner are reputed to have shot half that number each. Many other ‘sportsmen' have shot in the region of 250-300 animals during this time.[13] At the turn of the twentieth century, the area currently known as Ruhuna National Park was the Resident Sportsman's shooting reserve, a wild country reserved for the sporting pleasure of British residents in Sri Lanka.[14]
During the armed conflict in Sri Lanka, elephants were maimed or killed by land mines. Between 1990 and 1993, a total of 165 wild elephants died as a result of gunshot injuries. In 1994, at least 96 elephants were killed by poachers or land mines, and up to twenty elephants have fallen victims to land mines and been crippled.[15]
Today, given the rarity of tuskers in Sri Lanka, ivory poaching is not a major conservation issue. Nevertheless, some trade in ivory still goes on. Kandy has been identified as the centre for such illegal trade. The greatest threat to elephants comes from an expanding human population and its demand for land. Loss of significant extents of elephant range to development continues currently, with a number of irrigation and development projects leading to the conversion of more elephant ranges to irrigated agriculture and settlements.[6]
Between 1999 to the end of 2006 every year nearly 100 wild elephants were killed. Elephants are killed to protect crops and houses. Other threats are poaching, deforestation, drought and starvation. During drought seasons many elephants damage agricultural land for food. Nearly 80 elephants were killed in north western Sri Lanka, 50 in south and east, and another 30 in other parts of the country, totaling 160 elephant deaths in 2006 alone.[citation needed]

Conservation[edit]

Elephas maximus is listed on CITES Appendix I.[1]
The elephant conservation strategy of the Department of Wildlife Conservation aims at conserving as many viable populations as possible in as wide a range of suitable habitats as is feasible. This means protecting elephants both within the system of protected areas and as many animals outside these areas that the land can support and landholders will accept, and not restricting elephants to the protected area network alone.[6]
Under the British rulers, the elephant population decreased massively, as elephants were killed for their tusks. This is the main reason for their reduction of population.[citation needed]

Cultural depiction[edit]

Elephants were a common in Sinhalese heraldry for over two thousand years and remained so through British colonial rule. The coat of arms and the flag of Ceylon Government from 1875 to 1948 included an elephant and even today many institutions use the Sri Lankan elephant in their coat of arms and insignia.
An important cultural symbiosis has continued to exist between the elephant and humans for over two thousand years – no religious procession was complete without its retinue of elephants, and many large Buddhist temples in Sri Lanka had their own elephants.

Colombo


Situated in the western province of Sri Lanka, Colombo is the island's capital. Diverse and vibrant, the city is the administrative and economic center of the country. 
The history of the city itself dates to the 5th century. Due to its prime location on the western coast of Sri Lanka, Colombo grew as a seaport for trade between Asia and the West. It was used by the Moors, Romans, Arabs, Persians, and Chinese ships for the island's much sought after cinnamon and gems. 
It is said that the name Colombo was first introduced by the Portuguese in 1505 and is believed to be derived from the classical Sinhalese name 'Kolon thota' (port on the river Kelani) or 'Kola-amba-thota' (harbor with leafy mango trees). 
In 1593, the Portuguese, who had gained control of the Western coast of Sri Lanka, made Colombo their center. Subsequently, the Dutch, in 1638, joined with King Rajasingha II (King of Kandy) to battle and defeat the Portuguese in 1639. Colombo remained a central hub for the Dutch and the Dutch Maritime Provinces, controlled by the Dutch East India Company until 1796. At this point, the British captured the city, and in 1815, proclaimed Colombo the capital of Ceylon. It continues to remain so, even after Independence from the British in 1948. 
The city offers historical monuments, colonial architecture, beaches, and fine dining and shopping. Its architecture has been influenced by Portuguese, Dutch, and British colonization. The British influence is clearly visible in the buildings located in the Fort, an area where the larger business houses and the stock exchange are situated. Close by is Pettah, a bustling marketplace with each section of the bazaar selling its own specialty, ranging from food items to shoes to gold; wholesale markets are found here. 
The New Parliament is situated at Sri Jayawardenapura on the outskirts of Colombo, while the Old Parliament on Galle Road is now the Presidential Secretariat. 
Galle Face Green is where the locals gather on the weekend to enjoy the cool breeze from the Indian Ocean and a stroll along the promenade. Nearby are temples, mosques, and churches catering to the diverse population that enrich the culture of the city. 

Colombo is also your gateway to Sri Lanka. So, spend a day or two, and enjoy the blend of East and West. 









Wilpattu National Park



Situated 176 km. north of Colombo, Wilpattu is approximately 1,908 sq.km. in extent. It has a dense jungle cover which makes it a more exciting park where animals have to be tracked. There are numerous delightful little lakes - known as villus - and the leopard and sloth bear are the speciality rather than elephants.

Homeless elephants find refuge in Sri Lanka



They say an elephant never forgets, but what happens when an elephant is forgotten? In Sri Lanka, abandoned elephants who cannot survive in the wild find refuge at the Elephant Farm at Pinnewela (near Rambukkana).

People feed, groom and care for 46 elephants on the farm. The babies drink milk warmed to body temperature from super-size bottles, seven per feeding.
"Maybe at first they can't find their own food. So we bring it to them here," said Idris Salley, a caretaker at the elephant farm.
Outcasts like Raja, an old blind elephant who was wounded by hunters, live on the farm, as does an elephant rumored to have killed more than a dozen people.
The farm supports itself in part through tourists, who come for a rare close-up view of the animals.
The orphans arrive from across the country, rescued from remote villages where they have lost their mothers to quarry accidents, shootings or lynch mobs.
At the Elephant Orphanage, deep in the tropical hill country of central Sri Lanka, the motherless calves are raised by human foster parents who ply them with bottled milk five times a day and give them an occasional swig of beer in an effort to help preserve Asia's dwindling wild-elephant population.
"Without the orphanage, most of them would be left to die or be killed," said Wijepala Ranbanda, curator of the elephant orphanage.
In Sri Lanka and throughout Asia, some of the world's larger remaining wild-elephant herds - about 50,000 animals across the continent - face threats to their survival from burgeoning human populations that are bulldozing forests into farmland and severing centuries-old migration routes with highways and urban development.
In recent months the competition for space between man and beast has led to unprecedented clashes as the giant pachyderms, squeezed out of their native habitat, have attacked villagers, raided farm crops and, recently, stormed the outskirts of Calcutta.
India is home to an estimated 40 per cent of the world's Asianelephant population, which is overwhelmingly wild, with only a few thousand domesticated and used for work or religious purposes.
"The scenario is rather bleak," said J. C. Daniel, a member of the steering committee of India's Project Elephant, a new government effort to protect wild elephants. "The main problem facing us today is habitat destruction. There is frequent straying into human settlements, where they raid the crops and people shoot them."
A single rogue elephant was blamed for the deaths of 27 villagers during a 10-day rampage in the northeastern Indian state of Assam last fall. Other marauding elephants also attacked farmers, razed crops and guzzled barrels of rice beer stored in village huts. The government dispatched mounted troopers to hunt down the beasts.
In January, panic-stricken residents of Calcutta erected giant walls along the city's borders to stop a herd of elephants that had strayed from customary migration paths.
"There has been a human explosion in the area," said Ashish Ghosh, director of the Calcutta-based Zoological Survey of India, which has been studying elephant-migration patterns. "There have been more and more disturbances in their normal migration routes. This is the first time in recent memory that these herds have come so close to urban habitat."
In Sri Lanka, a small island nation that is home to an estimated 3,000 wild elephants, the problem of diminishing habitat is even more acute. The island has been stripped of 50 per cent of its forest land in the last three decades, dramatically affecting the elephant herds.
"They want to roam, and they overlap with the people," said curator Ranbanda of the Elephant Orphanage, which was created in 1975 by government officials worried about habitat encroachment.
In the last 19 years, the number of deserted, maimed and impaired elephants that are provided foster care has jumped from about 10 a year to 56 last year. Some of the orphans raised in the sanctuary of palm groves and rolling grassland are now rearing their own babies at the orphanage.
The sheer size of the elephants makes them far more susceptible to the problems of human encroachment than tigers, rhinoceroses and other endangered animals that tend to live in small pockets, wildlife officials said.
The orphanage's newest arrival weighed 60 kilograms (132 pounds) when she was born nearly two months ago. She will drink about 25 litres of milk a day until she's weaned after 4 1/2 years.
