Within the Asian region Sri Lanka has the highest species density for flowering plants, amphibians, reptiles and mammals. Sri Lanka also has the second highest population density of humans.

There are a large number of endemic species in Sri Lanka. This means that these species are found only in this country and in some instances only in particular areas or ecosystems where percentages are as -

Amphibians – 65%
Reptiles – 52%, Birds – 10%
Mammals – 5%

Sri Lanka, with the Western Ghats of India, is endowed with a rich biodiversity and considered, one of the 25 biodiversity hotspots in the world.

Examples of natural aquatic ecosystems are marshes, streams, rivers, estuaries, lagoons, coastal seas, sea grass beds and mudflats, mangroves and salt marshes, coral reefs, sandstone reefs and villus. Man-made aquatic ecosystems are tanks, reservoirs, canals, ponds and lakes.

Examples of natural terrestrial ecosystems are tropical wet evergreen forests, tropical submontane and montane forests, mixed evergreen forests, grasslands, scrub forest, Savannah, Sand dunes and beaches.
