Doga Dernegi (Partner Designate)

Site description A freshwater lake (max. 12,350 ha, max. depth 22 m) situated in a volcanic depression between Kýsýr and Akbaba mountains. Extensive marshes and damp pastures border the lake to the north-west, otherwise it is surrounded by hill pasture and has very little fringe vegetation. Four islands are vegetated with low shrub. Human activities include stock-grazing; water is used for hydroelectric power generation and irrigation.

Key Biodiversity Pelecanus sp. formerly bred on the islands. There are recent records of P. onocrotalus and occasional records of P. crispus, but breeding has not been proven for either species. Melanitta fusca is also thought to breed.
