Conservation Value Sinharaja
Conservation Value Sinharaja is the last extensive primary lowland tropical rain forest in Sri Lanka. It holds a large number of endemic species of plants and animals, and a variety of plants of known benefit to man. Sinharaja Forest Reserve is the last viable remnant of Sri Lanka’s tropical lowland rain forest; over 60% of the trees are endemic and many of these are rare; and there are 21 endemic bird species, and a number of rare insects, reptiles and amphibians (IUCN Technical Evaluation).
The long-term success of conserving Sinharaja depends upon the sustainable development of its buffer and peripheral zones through a participatory approach emphasizing the involvement of local people. Construction of hotels on peripheral zones and constructions of roads over the protected areas are bound to result in irrecoverable damages to this world heritage site.
