Doga Dernegi (Partner Designate)

Site description Two major streams, groundwater, and surface water feed the second largest lake in Turkey (max. 190,000 ha, max. spring depth 1.5 m). Brackish marshes have formed where channels and streams enter the lake. Tuz lake is extremely saline and almost completely dries up during the summer. The lake is surrounded by arable fields, except in the south and south-west where extensive seasonally-flooded salt-steppe occurs. Economic activities include salt extraction.

Key Biodiversity The main Turkish breeding colony of Phoenicopterus ruber is present on a group of islands in the southern part of the lake. Falco naumanni is a common breeder in surrounding villages.
