Wildlife of Sri Lanka

Wildlife of Sri Lanka includes its flora and fauna and their natural habitats. Sri Lanka has one of the highest rates of biological endemism (16% of the fauna and 23% of flowering plants are endemic) in the world even though it is relatively small.

Mammals

Sri Lanka is home to roughly 91 species of mammals, 41 of which are threatened (9 critically). 16 of the species are endemic, of which 14 are threatened, including the large Sloth Bear, the endemic Sri Lanka Leopard and Sri Lankan Elephant and the Sambar. Bats have the highest amount of species (out of 11 mammalian orders), with 30 different species. Sri Lanka's surrounding waters are home to 26 species of Cetaceans.

Reptiles

Sri Lanka currently contains 171 species of reptiles, of which 56 are threatened and 101 are endemic. Most of the reptiles are snakes and the largest are two species of Crocodile, the Mugger crocodile and Saltwater Crocodile.

Amphibians

Main article: List of amphibians of Sri Lanka

Sri Lanka has one of the most rich diversity of amphibians in the world, containing over 106 species of amphibians (over 90 of which are endemic) and has been claimed to have the highest amphibian species density in the world though that has been challenged. 52 species of amphibians in Sri Lanka are threatened, all but one of which are endemic.

Birds

Main article: List of birds of Sri Lanka

Sri Lanka is home to 227 species of birds (though some past estimates put it as high as 486), 46 of which are threatened (10 critically).

Fish

Sri Lanka contains 82 species of freshwater fish, of which 28 are threatened.

Flora

Diversity and endemism of plants in Sri Lanka are quite high. There are 3,210 flowering plants belonging to 1,052 genera. 916 species and 18 genera are endemic to the island. Additionally, all but one of the island’s more than 55 dipterocarps are confined to Sri Lanka. Although not lately assessed, Sri Lanka’s ferns are estimated at about 350 species. Diversity, richness, and endemism across all taxa groups are much higher in the wet zone than in the dry zone. Wet zone, which accounts for only a quarter of Sri Lanka’s land area, harbours 88 percent of the flowering plants, and 95 percent of country's flowering plant endemics. The natural forests of Sri Lanka are categorized into eight types.

Protected areas of Sri Lanka

Protected areas of Sri Lanka are administrated by Department of Forest Conservation and Department of Wildlife Conservation of Sri Lanka.There are 501 protected areas in Sri Lanka. The protected areas falls under supervision Department of Forest Conservation include forests defined in National Heritage Wilderness Area Act in 1988, forest reservations and forests manage for sustainability. World heritage site, Sinharaja Forest Reserve is an example for a National Heritage forest. There are 32 forests categorized as conservation forests including Knuckles Mountain Range. Strict nature reserves, national parks, nature reserves, forest corridors and sanctuaries recognized under the Flora and Fauna Protection Ordinance are managed by Department of Wildlife Conservation. Total of all categories of areas protected is 1,767,000 ha. Protected areas in Sri Lanka accounts for 26.5 percent of total area. This is a higher percentage of protected areas than in all of Asia and much of the World.

Biodiversity

Plant diversity and endemism in Sri Lanka are quiet high. Of 3,210 flowering plants belonging to 1,052 genera, 916 species and 18 genera are endemic. All but one of Sri Lanka's more than 55 dipterocarp (Sinhalese "Hora") are found nowhere else in the world. Sri Lanka's amphibian diversity is only becoming known now. Sri Lanka may be home to as many as 140 species of amphibians. More than 50 known freshwater crabs confined to Sri Lanka.

Deforestation

Between 1990 and 2000, Sri Lanka lost an average of 26,800 ha of forests per year. This amounts to 1.14 percent of average annual deforestation rate. Between 2000 and 2005 rate accelerated to 1.43% per annum.

Conservation effort

92 Key Biodiversity Areas (KBAs) have been identified through a process coordinated by the Wildlife Heritage Trust and University of Peradeniya. Many other data and published literature were also incorporated into the analysis, notably data on Important Bird Areas collected by the Field Ornithology Group of Sri Lanka. Nearly all of these KBAs lie in the wet zone in south western part of the country. These areas considered irreplaceable because all sites contain endemic species that found nowhere else, with some of them harboring more than 100 globally threatened species.
The flora and fauna of Sri Lanka are heavily understudied. For instance Serendib Scops Owl was described and nine other bird species added to the list of endemics only in 2004. Thus the number of endemic species is likely to be a gross underestimate.

Forest reserves and Proposed reserves

A number of forest reserves and proposed reserves are manage by Department of Forest Conservation. These areas are ecosystems with rich biodiversity. Some of the forest reserves and proposed reserves include

• Bambarabotuwa
• Beraliya proposed reserve
• Dellawa proposed reserve

• Gilimale-Erathna
• Kalugala
• Kekunandura
• Kombala-Kottawa

Apart from these international biosphere reserves there are national biosphere reserves being designated. 33 being administrated by Department of Forest conservation and another four by Department of Wildlife Conservation.

National protected areas

Depending on their objectives National protected areas are classified into mainly six types. First four categories of the protected areas cover all the ecological and regions of Sri Lanka. The 5, 6, 7 categories were introduced in 1993 by amending Flora and Fauna Protection Ordinance. Although there is no region declared under these categories so far.

1. Strict nature reserves
2. National parks
3. Nature reserves
4. Jungle corridors
5. Refuge
6. Marine reserves
7. Buffer zones

Gal Oya National Park in Sri Lanka was established in 1954 and serves as the main catchment area for Senanayake Samudraya. Senanayake Samudraya was built under the Gal Oya development project by damming the Gal Oya at Inginiyagala in 1950. An important feature of the Gal Oya National Park is its elephant herd that can be seen throughout the year. Three important herbs of the Ayurveda medicine, Triphala: Terminalia chebula, Terminalia bellirica and Emblica officinalis are amongst the notable flora of the forest. From 1954 to 1965 the park was administrated by the Gal Oya Development Board until the Department of Wildlife Conservation took over administration. The National Park is situated 314 km from Colombo.

Associated protected areas

The Gal Oya Development Board established several protected areas to protect the catchment areas of Senanayake Samundraya and several other reservoirs. This also helped to prevent the soil erosion caused by burning of the Thalawa grassland by the villagers. The protected areas established in 1954 are Gal Oya National Park, Senanayake Samudraya Sanctuary, Gal Oya valley north-east Sanctuary, and Gal Oya valley south-east Sanctuary. Together these four reserves accounts for 63,000 ha of land. Administration and protection of the four protected areas, reducing human-elephant clashes and enforcing the flora and fauna ordinance are amongst the duties of the department. Rangers are stationed in four sites: Inginiyagala, Mullegama, Nilgala and Baduluwela. Additionally in 1974 the Buddhangala Sanctuary was also designated. Buddhangala is a monastery with ruins of a stupa and other buildings in the nearby Malwattai area.
