History

The forest steeped in deep legend and mystery. The word Sinharaja means, lion (sinha) king (raja) and the popular belief is that the legendary origin of the Sinhala people in Sri Lanka is from the descendants of the union the lion king who once lived in the forest and a princess. Sinharaja Forest Reserve is one of the least disturbed and biologically unique lowland rain forests now remaining in Sri Lanka.

This forest covers an extent of approximately 11187 ha. From east to west the length of the forest is about 21 km. And its width from north to south is about 3.7 km. The Sinharaja forest was initially declared a Man and Biosphere Reserve (MAB) in 1978, as representative of Tropical Humid Evergreen Forest ecosystem in Sri Lanka and has been recognized by UNESCO as part of its International Network of Biosphere Reserves.

Subsequently it was declared a National Wilderness Area, under the National Heritage Wilderness Area Act, in 1988 and lately a World Heritage Site in 1989.It is the Sri Lanka 's first natural resource to earn this esteemed distinction. This forest is situated in the southwest lowland Wet Zone of the country at latitudes 6 21- 6 26 and longitudes 80 21- 80-34.It spans over the administrative districts of Ratnapura, Galle and Matara.

Sinharaja forest consists of a series of continuous ridges, aligned approximately in an east-west direction and lies between the tributaries of the Kalu Ganga in the north and the Gin Ganga in thesouth.There are four main routes of access to Sinharaja.

The Kalawana- Weddagala road from the northwest, The Rakwana-Morning side estate road from the northeast, the Hiniduma-Neluwa road from the southwest and Deniyaya-Pallegama road from the southeast. Among these roads the Kalawana-Weddagala road is shorter and more convenient for visitors traveling from Colombo.

Flora

The vegitation 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 up to 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 enormousOut 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, epiphytes as well.

Out of 25 genera 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 below 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 150 cm ranges between 45-55 individuals per hectare.

Fauna

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.

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 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.

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. Allow yourself sufficient time to roam about within this nature’s green cathedral and enjoy its beauty and majesty whether you be a photographer, artist, scientist or a nature lover.

Conservation

The Sinharaja forest reserve is composed of a Core zone and a Buffer zone. The core zone is composed of Tropical rain forest means wet tropical evergreen forest. But the buffer zone shows a diversity of forest types since it extends along a large sector of land.

The Sinharaja rain forest is gradients over to the south-western slope of central hills. Thus, the intermediate zone between the two zones composed of Wet, Lowland Montanez forests. Conservation current status of Sinharaja is in satisfied level.

Conservation status of Sinharaja is some what better than other forests of Sri Lanka. Sinharaja allocated to two zones like follows.

  1. Buffer Zone
  2. Core protected Zone

Buffer zone is at the border of Sinharaja forest and about 3.2km wide. Because of buffer zone contiguous human associated with only buffer zone and then core protected zone is secured.

Human Enrollment

Sinharaja is surrounded by 22 villages with a population of approximately 5000 people. Only two villages, Warukandeniya and Kolonthotuwa are located within the reserve. The long history of human habitation in and around today's reserve, in fact compounds the problem of managing and conserving the forest. Most of the ancient harmless are found along the southern boundary of the reserve on the bank of Gin Ganga with a few located on the north- western side. Numerous ancient footpaths exist on the periphery of the reserve while there are three footpaths that run across the interior of the forest.

The family structure is that of an extended family with parents, children and grand parents living together. The houses have small floor area, averaging 25 sq. meters and are constructed if wattle and daub. The roof is tatched with leaves of a forest treelet called Beru or with Bamboo leaves. Lately however, coconut leaves for tatching and clay tiles have begun to gain popularity as roofing materials.

The staple food of the villagers is rice, Yams such as sweet potato and Manioc (Cassawa), Breadfruit and Jak fruit, grown in home gardens are often used as substitutes for rice. Other plants commonly found in home gardens are vines of betel (Piper betel) black pepper and passion fruit. Fruit trees such as papaya and banana are also grown. For most of their other needs the villagers depend on plants often found in the forest. The sap needed for the manufacture of Jaggery is obtained tapping the in Florence of the Kitul palm ( Caryota urens ).

Another source of income is the manufacture of baskets and mats from rattan on 'wewal'. The villagers also exploit other plant products such as wild cardamon, resinuous exudates used as fumigating agents from Nawada ( Shorea stipularis ) and other shorea species.
