Dense, dark, wet and mysterious - Sinharaja is a primeval forest for meditation, relaxation and for scientific exploration. This relatively undisturbed expanse of primary forest is a Sri Lankan heritage - the last patch of sizeable lowland evergreen Rain Forest still remaining more or intact or undisturbed in our island.
The forest is steeped in deep legend and mystery. The word Sinharaja means, lion (Sinha) king (Raja) and the popular belief it that the legendary origin of the Sinhala people in Sri Lanka is form the descendants of the union the lion king who once lived in the forest and a princess.
Today, the spirit of the legend remains captured in solitude in the silent forest and the rising mist of the early dawn. More than time however separates the modern explorer in the Sinharaja forest from its legendary inhabitants, man has rapidly penetrated the seemingly inaccessible wilderness of the Sri Lanka's rainforest which once covered perhaps over 100,000 ha. of the South Western hills and lowlands. The present reserve is but a glimpse of its former glory, occuphying a narrow silver of land 21 km. in length and 3.7 km. in width, covering 11187 ha. of undisturbed and logged forest, scrub and fern land. It was declared an International Man and Biosphere Reserve by UNESCO in 1978, then a National Wilderness Area in 1988 under the National Heritage Site in 1989.
To the casual observer, the forest represents a tropical rain forest with a dense tall stand of trees, steep and rugged hills etched by numerous rocky streams and rivulets. The value of forests such as Sinharaja are well known for their functions as watersheds and store houses of great biological wealth. It is a rich treasure treasure trove of nature with a great diversity of habitats and a vast repository of Sri Lanka's endemic species found no where else in the world. Sinharaja therefore, represents an irreplaceable genepool, a refugia for all those rare and endangered forms of life, both fauna and flora.
Sinharaja forest reserve is one of the least disturbed and biologically unique lowland rain forest in Sri lanka. This forest covers an extent of about 11187 hectares from east to west .The length of the forest is about 21km and width from North to South is about 3.7km.It was declared a Man and Biosphere Reserve (MAB) in 1978,as representative of tropical humid evergreen forest Eco system in Sri Lanka and has been recognized by UNESCO as part of it?s International Network of Biosphere reserves. 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 the country in the districts of Ratnapura, Galle and Matara.

Flora of Sinharaja
The vegetation of Sinharaja may be described either as a tropical lowland rain forest or tropical wet evergreen forest.some striking characteristics of the forest are the loftiness of the dominant trees, the straightness of their bole, the abundance of regeneration and the diversity of species. Average height of the trees varies between 35m ? 40m.some individuals rise even upto 50m.The vegetation of Sinharaja is that of humid wet evergreen forest type with a high degree of endemism. In fact some families such as Dipterocarpaceae show an endemism more than 90%. The untapped genetic potential of Sinharaja flora is enormous.
Out of the 211 woody trees and lianas so far identified within the reserve 139 (66%) are endemic. Similarly, high levels of endemism are perhaps true for the lower plants like ferns, epiphyts as well.out of 25 general endemic to Sri Lanka 13 are represent in Sinharaja. The Total vegetation density, including trees, shrubs, herbs and seedlings has been estimated to be around 240,000 individuals per hectare, of which 95% comprise individuals of the ground layer bellow 1m in height.The density of trees, lianas above 30 cm girth at breast height, ranges between 600 ? 700 individuals per hectare while the number of merchantable individuals of trees of girth grater than 150cm ranges between 45-55 individuals per hectare.
Fauna of Sinharaja
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%. There have been reports of sightings of a few animals in the eastern Secter.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. Badger Mongoose and the Golden Palm Civet have been occasionally sighted. The most commonly seen primate is the Purple - faced Leaf Monkey.Although the elephants said to be common in the past, there have not been reports of sightings during the last 15 years.
Out of the Birds recorded in the western sector of the reserve, 72% were resident non-endemic and 13% migrants. One of the most interesting and colorful spectacles to be found in the in the Sinharaja is the presence of mixed species of foraging bird flocks, a phenomenon commonly found in rain forests total of 100 such flocks were systematically observed, and studies have revealed that some flocks contained 48 species including 12 endemic species. 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. The Agamids are the best represented group of reptiles, the most common being the Green Garden Lizard. Of Special significance are the sightings of Calotes Liolepis an arboreal species, the rearest of all agamids found in the island .The only Tortoise recorded in the reserve is the Hard - shelled Terrapin, while of the species of skinks, the spotted skink can be seen often. Among the snakes The Green Pit Viper and Hump-nosed Viper are commonly found in this forest and are endemic to Sri Lanka.
The amphibians are fairly well represented in the reserve and nine endemic species have been identified. The endemic Torrent toad and the common house toad. In most streams and marshes, the Wrinkled frog and The Sri Lankan Reed frog is also found in Sinharaja. Ramanella palmata a rare endemic species is the only microhylid recorded so far while the yellow-banded Caecilian is the only apodan recorded.
It is desirable that you, who visit the forest, be sensitive to the need to conserve forests such as Sinharaja.Contray to the chaos and congestion prevailing in urban areas, it is in forests that the quality of life is best expressed. In addition man finds peace and tranquillity in forest.
