Sinharaja Forest Reserve is a national park and a biodiversity
hotspot in Sri Lanka. It is of international significance and has been
designated a Biosphere Reserve and World Heritage Site by UNESCO.
The hilly virgin rainforest, part of the Sri Lanka lowland rain forests
ecoregion, was saved from the worst of commercial logging by its
inaccessibility, and was designated a World Biosphere Reserve in 1978 and a
World Heritage Site in 1988. The reserve's name translates as Kingdom of the Lion.
The reserve is only 21 km (13 mi)
from east to west, and a maximum of 7 km (4.3 mi) from north to
south, but it is a treasure trove of endemic species, including trees, insects,
amphibians, reptiles, birds and mammals.
Because of the dense vegetation, wildlife is
not as easily seen as at dry-zone national parks such as Yala. There are about
3 elephants and the 15 or so leopards are rarely seen. The most common larger
mammal is the endemic Purple-faced Langur.
An interesting phenomenon is that birds tend
to move in mixed feeding flocks, invariably led by the fearless Greater
Racket-tailed Drongo and the noisy Orange-billed Babbler. Of Sri Lanka's 26
endemic birds, the 20 rainforest species all occur here, including the elusive Red-faced
Malkoha, Green-billed Coucal and Sri Lanka Blue Magpie.
Reptiles include the endemic Green pit viper
and Hump-nosed vipers, and there are a large variety of amphibians, especially tree
frogs. Invertebrates include the endemic Common Birdwing butterfly
and the inevitable leeches.

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. 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 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. 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.
