A hyper-eutrophic freshwater lake directly east of the village of Srebarna, on the bank of the River Danube between kilometres 393 and 391. The open-water surface is partly covered by Hydrocharis, Nymphaea and Potamogeton, and is fringed by reedbeds of Phragmites and Typha. There are some groups of Salix in the reedbeds. Komluka island (in the Danube), which is part of the reserve, is covered by flooded forest of Salix and Populus. Plantations of Robinia and Eleagnus cover the surrounding hills.
The site is important for breeding waterbirds, especially the globally threatened Pelecanus crispus, and for wintering geese. Species of global conservation concern that do not meet IBA criteria: Anser erythropus (has occurred in the past), Branta ruficollis (12-50 in winter), Haliaeetus albicilla (1-5 in winter; extinct as a breeding species).
Pressure/threats to key biodiversity
Threats include nest-predation by foxes Vulpes vulpes, jackals Canis aureus and boars Sus scrofa, which affect the pelican colony (`Natural events', above). Some restoration measures were taken by the Ministry of Environment in response to the disturbed water-levels in the lake.
