Site details
Site description: A highly saline lake located west of Tuz lake (site 072) and surrounded by arid hills and dry steppe-grasslands. The lake is fed by surface flow with additional inputs from sulphurous springs in the north and a channel that brings drainage water from Konya city. Economic activities include salt extraction.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that was identified using previously established criteria and thresholds for the identification of Important Bird and Biodiversity Areas (IBAs) and for which available data indicate that it does not meet global KBA criteria and thresholds set out in the Global Standard.
Additional biodiversity: The site is important for a range of breeding waterbirds.

Threats
Summary of threats to biodiversity at KBA: The nutrient-rich inflow from the Konya drain is causing the salt-tolerant vegetation at the southern end of the lake to be replaced by freshwater marsh vegetation. The lake's hydrology is managed to suit industrial needs, and this, along with possible pollution from industrial processes, may have a negative effect on the lake's ecology.
| Threat level 1 | Threat level 2 | Threat level 3 | Timing |
