Sinharaja
Sinharaja Rain Forest (a UNESCO World Heritage Site), the last viable remnant of Sri Lanka’s tropical lowland rainforest spanning an area of 18900 acres is located within Sabaragamuwa and Southern provinces of the south-west lowland wet zone of Sri Lanka. Sinharaja is bounded by rivers on three sides. On the north, Sinharaja is bounded by the Napola Dola and Koskulana Ganga. On the south and south-west are the rivers Maha Dola and Gin Ganga. On the west are the river Kalukandawa Ela and river Kudawa Ganga. To the east of Sinharaja is an ancient footpath near Beverley Tea Estate and by the Denuwa Kanda. 6°21′-6°26’N, 80°21′-80°34’E.
Most of the area of Sinharaha forest was originally declared a forest reserve under the Waste Lands Ordinance in 1875. In 1978, Sinharaja Rain Forest was included in the international network of biosphere reserves, established and maintained as part of UNESCO’s Man and the Biosphere (MAB) program. In October 1988, this reserve, together with a northeastern extension of it, was declared Sri Lanka’s first National Wilderness Heritage Area. In December 1988, the Sinharaja Biosphere Reserve became Sri Lanka’s first natural site to be added to UNESCO World Heritage list.
