Sri Lanka
Flora and fauna

Western Ghats of India and Sri Lanka were included among the first 18 global biodiversity hotspots due to high levels of species endemism. The number of biodiversity hotspots has now increased to 34. Sri Lanka has the highest biodiversity per unit area among Asian countries for flowering plants and all vertebrate groups except birds. A remarkably high proportion of the species among its flora and fauna, 27% of the 3,210 flowering plants and 22% of the mammals, are endemic. Sri Lanka supports a rich avifauna of that stands at 453 species and this include 240 species of birds that are known to breed in the country. 33 species are accepted by some ornithologists as endemic while some ornithologists consider only 27 are endemic and the remaining six are considered as proposed endemics. Sri Lanka's protected areas are administrated by two government bodies; The Department of Forest Conservation and the Department of Wildlife Conservation. Department of Wildlife Conservation administrates 61 wildlife sanctuaries, 22 national parks, four nature reserves, three strict nature reserves, and one jungle corridor while Department of Forest Conservation oversees 65 conservation forests and one national heritage wilderness area. 26.5% of the country's land area is legally protected. This is a higher percentage of protected areas when compared to the rest of Asia.

Sri Lanka contains four terrestrial ecoregions: Sri Lanka lowland rain forests, Sri Lanka montane rain forests, Sri Lanka dry-zone dry evergreen forests, and Deccan thorn scrub forests. Flowering acacias flourish on the arid Jaffna Peninsula. Among the trees of the dry-land forests are valuable species such as satinwood, ebony, ironwood, mahogany and teak. The wet zone is a tropical evergreen forest with tall trees, broad foliage, and a dense undergrowth of vines and creepers. Subtropical evergreen forests resembling those of temperate climates flourish in the higher altitudes.

Yala National Park in the southeast protects herds of elephant, deer, and peacocks. The Wilpattu National Park in the northwest, the largest national park, preserves the habitats of many water birds such as storks, pelicans, ibis, and spoonbills. The island has four biosphere reserves: Bundala, Hurulu Forest Reserve, the Kanneliya-Dediyagala-Nakiyadeniya, and Sinharaja. Sinharaja is home to 26 endemic birds and 20 rainforest species, including the elusive red-faced malkoha, the green-billed coucal and the Sri Lanka blue magpie. The untapped genetic potential of Sinharaja flora is enormous. Of the 211 woody trees and lianas within the reserve, 139 (66%) are endemic. The total vegetation density, including trees, shrubs, herbs, and seedlings, has been estimated at 240,000 individuals per hectare. The Minneriya National Park borders the Minneriya Tank, which is an important source of water for elephants inhabiting the surrounding forests. Dubbed "The Gathering", the congregation of elephants can be seen on the tank-bed in the late dry season (August to October) as the surrounding water sources steadily disappear. The park also encompasses a range of micro-habitats which include classic dry zone tropical monsoonal evergreen forest, thick stands of giant bamboo, hilly pastures (patanas), and grasslands (talawas).

During the Mahaweli Program of the 1970s and 1980s in northern Sri Lanka, the government set aside four areas of land totalling 1,900 km (730 sq mi) as national parks. Statistics of Sri Lanka's forest cover show rapid deforestation from 1956 to 2010. In 1956, 44.2 percent of the country's land area had forest cover. Forest cover depleted rapidly in recent decades; 29.6 percent in 1999, 28.7 percent in 2010.
