The Sinharaja Forest Reserve, the best-known rainforest in Sri Lanka, is well worth a visit from anyone who is interested in the natural resources of this country. It has been declared a World Heritage Site, because of its unique and high biodiversity.
Sinharaja is also a Man and Biosphere Forest Reserve, and a large proportion of the flora in this forest is endemic to the country. Some species are endemic to the Sinharaja Forest itself. Sinharaja also has many species of endemic fauna. Situated in the south-west lowland wet zone of Sri Lanka and falling into the Sabaragamuwa and Southern provinces, Sinharaja is surrounded by Napola Dola, Koskulana Ganga (north), Maha Dola, Gin Ganga (south-west), the Kalukandawa Ela, Kudawa Ganga (west), Beverley Tea Estate and Denuwa Kanda (east). As a rainforest with its rich and complex diversity of vegetation, Sinharaja provides habitats for a variety of animals. Although dependent on plants for food, animals also carry out certain functions vital to the growth of some plants. Pollination and seed dispersal are two of these.
