Srebarna Nature Reserve protects a lake and wetland ecosystem of 638ha located near to the village of Srebarna on the west bank of the Danube River. The reserve includes the lake and the former agricultural lands north of the lake, a belt of forest plantations along the Danube, the island of Komluka and the aquatic area locked between the island and the riverbank.
Srebarna Nature Reserve is an important wetland on the Western Palaearctic bird migratory flyway. It provides nesting grounds for 99 species of birds and seasonal habitat to around 80 species of migratory birds. The property is surrounded by hills which provide a natural boundary and offer an ideal means for observing the waterfowl. - in: http://whc.unesco.org/en/list/219
