context_page_description: Sri Lanka, officially the Democratic Socialist Republic of Sri Lanka, is an island country in South Asia, located in the Indian Ocean southwest of the Bay of Bengal and southeast of the Arabian Sea. It is geographically separated from the Indian subcontinent by the Gulf of Mannar and the Palk Strait. Sri Jayawardenepura Kotte is its legislative capital, and Colombo is its largest city and centre of commerce.
  Sri Lanka's documented history spans 3,000 years, with evidence of prehistoric human settlements dating back at least 125,000 years. It has a rich cultural heritage, and the first known Buddhist writings of Sri Lanka, the Pāli Canon, date back to the Fourth Buddhist council in 29 BC. Its geographic location and deep harbours made it of great strategic importance from the time of the ancient Silk Road through to the modern Maritime Silk Road. Its location as a major trading hub made it known to both the far East as well as the European continent from as far back as the Anuradhapura period. The country's trade in luxury goods and spices attracted traders of many nations, creating Sri Lanka's diverse population.
context_section_description: Lying within the Indomalayan realm, 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. 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 has declared 24 wildlife reserves, which are home to a wide range of native species such as elephants, leopards, sloth bears, the unique small loris, a variety of deer, and the purple-faced langur.
  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).
  
  Sri Lanka is home to over 250 types of resident birds, with 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. Sri Lanka's forest cover, which was around 49% in 1920, had fallen to approximately 24% by 2009.
