Sinharaja Forest Reserve, Sri Lanka

Sinharaja Forest Reserve is probably the best kept secret in Asia – Sinharaja is one of the least disturbed and biologically unique lowland rain forests in Sri Lanka.

Location and Area

Sinharaja is a vast forest which covers an area of approximately 11,000ha, is now a UNESCO World Heritage Site. Located quite close to Ratnapura with approaches from other directions as well, this dense rain forest has an amazing variety of flora and fauna, and this has caught the attention of scientists as well as nature lovers who make excursions into the jungle to explore and appreciate its many natural wonders.  Among these are cool waterfalls, rushing streams and crystal clear freshwater streams. A lot of attention and emphasis is now being placed on the conservation of this precious treasure that is Sinharaja.

This rain forest covers an extent of about 11187 hectares from east to west of Sri Lanka. The length of the Rain forest is about 21km and width from North to South is about 3.7km. It was declared a National wilderness area in 1988 and lately a world heritage site in 1989. It is situated in the southwest lowland wet zone of Sri Lanka in the districts of Ratnapura, Galle and Matara. The average annual temperature of Sinharaja is 23.6 C. Rainfall figures show values ranging from 3,700 to 5,000 in and around the Sinharaja forest.


The vegetation of Sinharaja forest is evergreen forest type with a high degree of endemism. In fact some families show an endemism more than 90%. The untapped genetic potential of Sinharaja flora is enormous. Average height of the trees varies between 35m – 40m.some individuals rise even up to 50m.

Out of the 211 woody trees so far identified within the reserve 139 (66%) are endemic. Similarly, high levels of endemism are perhaps true for the lower plants like ferns, epiphytes as well. Out of 25 general endemic to Sri Lanka 13 are represented in Sinharaja forest.


Studies on the fauna of Sinharaja have revealed that there is a high degree of endemism among the butterflies, fish, amphibians, reptiles, birds and mammals are greater than 50%.The most common deer species is the Sambhur, The Monk deer and Barking deer are also found within the reserve. Leopards are very seldom sighted, but their frequent presence has been confirmed by tracks and other signs.

The rare endemic birds to be seen in Sinharaja are the Red-faced Malkoha, the Sri Lanka Blue Magpie, the Ashy-headed Barbbler, and the White – headed Starling and the Green – billed Coucal the rarest of Sri Lankan birds.
