Biological diversity of Sri Lanka

Sri Lanka is an island, 65,610 km2 in area situated close to the Southeast corner of the peninsula of India. Despite its relatively small size, Sri Lanka possesses a high level of bioddiversity. A nortworthy feature of Sri Lanka's biodiversity is the remarkable high proportion of endemic species among its flora and fauna: 23% of the flowering plants and 16% of the mammals in the island are endemic. Sri Lanka has a wide range of topographic and climatic variation and this contributes to the special features of its biodiversity.

Sri Lanka: One of 25 World's Biodiversity Hot Spots

Sri Lanka has been identified by the environment activist group Conservation International (CI) as one of 25 biodiversity hot spots in the world, reported the Time weekly in its January 11 issue.

These hot spots could have maximum benefit by preservation efforts, the magazine said in a cover story titled "Heroes for the Planet: Earth Angles". The U.S.-based CI said that together with Western India, Sri Lanka, the island in the Indian ocean, accounts for 2,180 plant species that are unique to each hot spot.

Sri Lanka's tropical rain forest ecosystem is considered as an area which is disturbed by human activity, but still exceptionally rich in animal and plant species found nowhere else.
