Sinharaja Rain Forest Sri Lanka

This virgin rainforest has become one of Sri Lanka's major eco tourism destinations. Described as both a Tropical Lowland Rainforest and a Tropical Wet Evergreen Forest, the Sinharaja is a vast repository of wildlife that is endemic to Sri Lanka. 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. Of the endemic birds, the rarest to be seen here are the Red Faced Malkoha, Green Billed Coucal and the Sri Lankan Blue Magpie. Endemism among mammals and butterflies is also greater than 50 percent.

Endemic Birds at the Sinharaja Rain forest Sri Lanka

Ninety five percent of Sri Lanka’s endemic birds are present in Sinharaja making it a birding expedition unlike any other. Another interesting sight to be found in Sinharaja is the presence of mixed species of foraging bird flocks, a phenomenon commonly found in rain forests.  A hundred such flocks have been systematically observed, and studies have revealed that some flocks contained 48 species including 12 endemic to the island. The rare endemic birds to be seen in the Sinharaja Rainforest are the Red-faced Malkoha, the Sri Lanka Blue Magpie, the Ashy-headed Babbler and the White-headed Starling. The Green–billed Coucal has been given the title of being the Rarest of Sri Lankan birds.
Big game and other mammals encountered in the Sinharaja Rainforest

wildlife in Sinharaja rain forest Sri Lanka although elephants were said to be common in the past, there have been fewer reported sightings in the Sinharaja Rainforest during the past 15 years. There is a small herd of Sri Lankan elephants that reside here but is rarely seen. Other animals that have been spotted are the Sambar Deer, the Mouse Deer and Barking Deer.

Though seldom sighted, it is estimated that 15 Sri Lankan leopards live within the confines of this nature reserve while the Brown Mongoose and the Golden Palm Civet have been occasionally spotted. The most commonly seen primate however is the Purple Faced Leaf Monkey.

Reptiles and Amphibians at the Sinharaja Nature Reserve

The most common reptile is the Green Garden Lizard.  The Calotes liolepis an arboreal species and the rarest of all agamids found on the island.  The only Tortoise recorded on the reserve is the Hard-shelled Terrapin.

The Wrinkled Frog and the Sri Lankan Reed Frog are also found in most streams and marshes.

Flora at the Sinharaja Rainforest, Sri Lanka

The vegetation in 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 trunks, the abundance of regeneration and the diversity of species. The average height of the trees varies between 35 to 40 metres. Some trees rise even up to a staggering 50 metres. The vegetation in Sinharaja is that of a humid wet evergreen forest with a high degree of endemism. 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 percent) are endemic to Sri Lanka. Similarly, high levels of endemism are perhaps true for the lower plants like ferns, and out of the 25 which are endemic to Sri Lanka, 13 are represented in the Sinharaja Rainforest. The total vegetation density, including trees, shrubs, herbs and seedlings has been estimated to be around 240,000 plants per hectare of which 95 percent comprise those of the ground layer, below one metre in height.

The Sinharaja Rainforest - History and Geography

A virgin age-old rainforest like Sinharaja does not come without its fair share of vibrant history. The name itself translates into the ‘Kingdom of the Lion’ and according to legend, Sri Lankans are said to be descendants of the coupling of a princess and the lion king who lived in this forest.  Being one of the last remaining and least disturbed biodiversity hotspots in Sri Lanka, the Sinharaja Rainforest was designated a UNESCO Biosphere Reserve in 1978 and then a UNESCO World Heritage Site in 1988. It is Sri Lanka's first nature reserve to earn this esteemed distinction.

This unique forest covers an area of approximately 11,200 hectares, measuring 21 kilometres from east to west, and just less than 4 kilometres from north to south. The Sinharaja Rainforest is situated in the southwest lowland Wet Zone of Sri Lanka and extends into the administrative districts of Ratnapura, Galle and Matara. The forest consists of a series of continuous ridges, aligned approximately in an east-west direction and lies between the tributaries of the Kalu Ganga (river) to the north and the Gin Ganga to the south.

The elevation of the Sinharaja Reserve ranges from 200 to 1,300 metres. It has a rolling terrain and the Hinipitigala Peak is the tallest, rising up to approximately 1,150 metres. Other important mountains in the reserve range between 550 to 900 metres in height,  namely Moulawella (760 m), Kosgulana (797 m), Sinharaja (742 m), Kohilearambe (575 m), Dotalugala (769 m) and Tibbottagala (904 m).

Getting the most out of your Sinharaja Rainforest bird and nature tour

Since there are no vehicles allowed inside this nature reserve, tours take place in the form of walking trails, where you start off early in the morning and return either by lunch, set off again in the evening or spend the whole day in the forest. So naturally, having a top notch naturalist guide is a must. Bird enthusiasts may want to keep a record of daily sightings and the guides at Mahoora are expert birders and will provide you with binoculars so that you can do this with ease.

Climate at the Sinharaja Rainforest

The Sinharaja Rainforest lies within a rainfall range of 3,000 to 6,000 millimeters annually. The average temperature ranges between 20°C to 25°C.
