Sinharaja Rain Forest - UNESCO World Heritage Site
Declared a Bio sphere reserve and a UNESCO world heritage site, Sinharaja Rain forest is considered one of the finest virgin rain forest areas left on the planet, with a remarkably high diversity of plant species making it part of the bio diversity hotspots in the world. The reserve is only 21 km (13 miles) from east to west, and a maximum of 7 km (4.3 miles) from north to south, but it is truly 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 a dry-zone national parks such as Yala. Records indicate of about 3 elephants and 15 or so leopards but are rarely seen. The commonest larger mammal is the endemic Purple-faced Langur.
However it's a heaven for bird lovers, the birds tend to move in mixed feeding flocks, invariably led by the fearless Greater Racket-tailed Drongo and the noisy Orange-billed Babbler and is an interesting phenomenon. Out of Sri Lanka's 26 endemic birds, all 20 rainforest species are seen 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.
