Koskulana Mini Hydro Power Project, Sri Lanka

Upon inquiry PILF became aware that the mini hydro power project was right on the boundary of the Sinharaja World Heritage Site, last remaining relatively undisturbed remnant of tropical humid evergreen forest in Sri Lanka


Description

After having exploited all feasible sites for big hydro, Sri Lanka has turned to the development of smaller projects. Many streams have been marked as potential for building mini-hydro projects and already about 37 are in construction or evaluation phase, revealed CEJ member Hemantha Withanage. A mini hydro power plant of 0.6MW is being constructed on the Koskulana River, within the 100m buffer zone of Sinharaja Forest Reserve. Sinharaja rain forest located in the South- West of Sri Lanka was declared back in 1875 as a reserved forest in terms of Ordinance No.24 of 1848 (an Ordinance to regulate the felling and removal of Timber grown on Crown Lands of Sri Lanka). In 1978, Sinharaja was recognized as an International Man and Biosphere Reserve by UNESCO. In 1988, it was declared as a National Heritage and Wilderness Area under the National Heritage and Wilderness Areas Act No.3 of 1988 of Sri Lanka. In the same year it was inscribed on the world heritage list of UNESCO. The inscription as a world heritage was justified as ‘Sinharaja is the last remaining relatively undisturbed remnant of tropical humid evergreen forest in Sri Lanka’ and its endemism is extremely high with at least 139 species of endemic plants and its faunal endemism particularly for birds, mammals and butterflies exceeding 50%.  Sinharaja is also an important watershed, as a network of waterways generating from it feed two major rivers, Gin Ganga and Kalu Ganga.
