Nature Trails in Sinharaja Rain Forest , Sri Lanka

Rain Forest Exploration - Sri LankaSINHARAJA RAINFOREST is a world heritage site and major eco tourism destination, which can also be described as a Tropical Lowland Rainforest or Tropical Wet Evergreen Forest . Whatever its 'technical' name, it is undoubtedly a rich 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. BIRD WATCHING in this ecosystem is particularly interesting because it is home to 95% of the endemic birds of Sri Lanka ! Named as a world heritage site in 1989, this lowland evergreen rain forest is steeped in deep legend and mystery. The word 'Sinharaja' means, Lion (Sinha) King (Raja), and it is popular belief that the legendary origin of the Sinhala people is from the union between a princess and the lion king who once lived in the forest!

Sinharaja valued at Rs. 18 billion per annum

The first ever value survey on the Sinharaja forest, based on international valuation, has placed it at an annual price tag of USD 188.47 million or Rs.18.84 billion.

Sinharaja which was designated a World Biosphere Reserve in 1978 and a World Heritage Site in 1998 has been given this price considering its value at key ecosystem services by the Ministry of Environment and Natural Resources.

The Services include re-creation capacity, non-timber forest product and genetic resources, among other benchmarks.

The bulk of the land area in Sinharaja was declared a forest reserve in 1875 under the Waste Lands Ordinance and today it remains the last primary lowland tropical rain forest in the country.

Meanwhile a similar study on ecosystem services of Mangrove Ecosystems of the country has attached a total value of USD 57.8 to them.

The Ministry which has so far worked out the calculations only for these two ecosystems maintains that non-availability of data has restricted it from carrying out similar studies on other ecosystems here.

 

"Week Without Walls (WWW)  - OSC & Eco Team

This year [2008] signaled a grand return to past OSC tradition; from the January 15 to 18 , the Overseas School of Colombo re-established its "Week Without Walls (WWW)" programme.

Designed for the secondary school, WWW is an "out of classroom" experience for students that is designed to enrich them with a better knowledge of their host country and its environment.

WWW an effort to develop and enhance greater social and cultural awareness. WWW emphasizes holistic learning, intercultural awareness and communication. It helps students to bond with their peer groups in environments outside of school.

At the Overseas School of Colombo, WWW this year was an exciting time for all students participating.

Eco Team was the obvious choice by the OSC and their appointed travel coordinator - United Holidays, to be the service provider for 2 wilderness camps in Singharaja Rain Forest and Hatton. Singharaja camp was coupled with a rainforest exploration  programme conducted by Eco Team's expert naturalists whilst the Hatton Camp coupled with an Adam's Peak expedition backed by Eco team Trekkers & Guides.

  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 the south.

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 .
  Topography:

The elevation of the Sinharaja reserve ranges from 200m to 1300m. It has a rolling terrain consisting of a series of ridges and valleys, which assumes an east-west trend in the northwestern part of the reserve. In other parts of the reserve, the ridges and valleys assume a north-west/south-east alignment. The peak of Hinipitigala is the tallest, rising up to about 1150m.Other important ridges in the reserve ranges between 550-800m in height NamelyMoulawella (760m), Kosgulana (797m), Sinharaja (742m), Kohilearambe (575m), Dotalugala (769m), and Tibbottagala (904m).

 Geology and Soils:

The Sinharaja Reserve lies within the transition zone of two important groups of rock types, the south/western group which consist of metasediments-charnokites and scapolites bering calc granulites and the highland group comprising khondalites of metamorphosed sediments and Charnockites. The most significant geological feature of Sinharaja is the presence of a "Sinharaja Basic Zone" which comprises hornblend pyriclasts, basic charnokites pyroxene amphibolites and scapolite.

The soils of Sinharaja largely belong to the group of Red Yellow Podzolic soils, with clearly distinguishable horizons of varying soil depths. The soil is well drained with very little accumulation of organic matter.

  Plant Life:

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.

The average height of the trees varies between 35m -40m. Some individuals rise even upto 50m.

Contrary to popular belief scrub growth does occur on rock shelves or gaps on the canopy created by falling of over-mature trees. The great diversity of species of Sinharaja forest makes it difficult to distinguish ecological patterns. However, some tree associations have been recognized and these are the Dipterocarpus (Hora-Bu Hora) an association confined to the lower elevations along the Gin Ganga valley and the Mesua-Doona (Shorea) association forms the matrix of the Sinharaja forest.

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 represented 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 30cm girth at breast height, ranges between 600-700 individuals/ha. While the number of merchantable individuals of trees of girth greater than 150cm. Ranges between 45-55 individuals/ha.

 
  Animal Life:

Preliminary 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. In fact 95%of the endemic birds of Sri Lanka are recorded in Sinharaja. Endemism among mammals and butterflies are also greater than 50%.

Out of the larger mammals, although elephants were said to be common in the past, there have not been reports of sightings during the last 15 years. However, there have been reports of sightings of a few animals in the Eastern Sector. The most common deer species is the Sambhur.The Mouse 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. Brown Mongoose and the Golden Palm Civet have been occasionally sighted. The most commonly seen primate is the Purple faced Leaf Monkey.

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. A 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 Babbler, 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 rarest 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 Lanka Reed frog also found in Sinharaja. Ramanella palmate a rare endemic species is the only microhylid recorded so far while the yellow- banded Caecilian is the only apodan recorded.

 
  It's People:

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.

The exudates from Kekuna ( Canarium zelani-cum ) is used as a caulk for damaged boats and as glue for domestic purposes. Numerous plants used in the native 'ayurvedic'system of medicine are also collected and sold by the villagers, of particular significance being the stem of Weniwel ( Coscinium fenestratum ) used by most Sri Lankan as an antidote for tetanus. Beraliya ( Shorea megistophylla ) provides a fruit which is often used as a substitute for flour.
