The Srebarna Biosphere Reserve
The Srebarna Biosphere Reserve, which also incorporates the Island of Devniya, is an area of just over 900 hectares situated in the northeast of Bulgaria on the River Danube. It includes Srebarna Lake which was connected to the Danube by a natural channel. This link was interrupted in the late 1940s when a dyke was constructed.
Sustained pressure following the area achieving Ramsar protection in 1975, and being declared a UNESCO Biosphere reserve in 1977, saw the dyke partially removed at the end of the 1970s.
In 1983 the Reserve was designated as a World Heritage Site and in 1990 became an Important Bird Area (IBA). A new canal was constructed in 1994 and the link finally restored. LINK Srebarna
