rainfall. An increase in average rainfall coupled with heavier rainfall events has resulted in recurrent flooding and related damages to infrastructure, utility supply and the urban economy. 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
