Flora and fauna

Lying within the Indomalaya ecozone, Sri Lanka is one of 25 biodiversity hotspots in the world. Although the country is relatively small in size, it has the highest biodiversity density in Asia. 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 has declared 24 wildlife reserves, which are home to a wide range of native species such as Asian elephants, leopards, sloth bears, the unique small loris, a variety of deer, the purple-faced langur, the endangered wild boar, porcupines and anteaters.
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.

The Sri Lankan Leopard (Panthera pardus kotiya) is an endangered subspecies of leopard native to Sri Lanka.

The Yala National Park in the southeast protects herds of elephant, deer, and peacocks. The Wilpattu National Park, the largest, in the northwest 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. Out of these, Sinharaja forest reserve is home to 26 endemic birds and 20 rainforest species, including the elusive Red-faced Malkoha, Green-billed Coucal and 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 numerous elephants (Elephus maximus) 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).
Sri Lanka is home to over 250 types of resident birds . It has declared several bird sanctuaries including Kumana During the Mahaweli Program of the 1970s and 1980s in northern Sri Lanka, the government set aside four areas of land totalling 1,900 km² (730 sq mi) as national parks. However the country's forest cover, which was around 49% in 1920, had been fallen to approximately 24% by 2009.
