Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(ii,iii,v)+2ab(ii,iii,v) ver 3.1
Year Published: 2014
Date Assessed: 2013-03-18
Assessor(s): Freyhof, J.
Reviewer(s): Ekmekçi, F., Küçük, F. & Smith, K.
Justification:
The species is endemic to Lake Burdur (250 km²) in Central Anatolia, Turkey. The slow desiccation of Lake Burdur is the major threat to this species. Water is massively abstracted and retained by dams in the Lake Burdur catchment and there is has been a climate change induced reduction in rainfall. The lake is strongly polluted, but while pollution seems not to impact the population it is unknown when a critical pollution level will be reached. The species is assessed as Endangered as its extent of occurrence is 250 km², its area of occupancy is estimated to be 100 km² (it is a littoral species), and it is found in only one location.

Range Description:The species is endemic to Lake Burdur (250 km²) a saline lake in Central Anatolia, Turkey.
Countries occurrence:
Native:
Turkey
Additional data:
Estimated area of occupancy (AOO) - km2:100Continuing decline in area of occupancy (AOO):Yes

Population [top]

Population:The level of Lake Burdur has fallen massively during the last three decades and the species is therefore believed to have declined.
Current Population Trend:Decreasing
Additional data:
Continuing decline of mature individuals:Yes

Habitat and Ecology [top]

Habitat and Ecology:It lives in the littoral zone of a saline lake.
Systems:Freshwater
Continuing decline in area, extent and/or quality of habitat:Yes
Movement patterns:Not a Migrant

Threats [top]

Major Threat(s): The slow desiccation of Lake Burdur is the major threat to this species. The reasons for the drying out of Lake Burdur are outside the lake itself. Lake Burdur dries out as water is massively abstracted and retained by dams in its catchment, and as there is reduction in rainfall induced by climate change. The lake is strongly polluted, but pollution seems not to impact the population. However it is unknown when a critical pollution level will be reached. The salinity of the lake is also increasing, and the species has been observed congregating close to freshwater springs where salinity is lower, indicating that the salinity levels in the lake may be reaching levels that the species cannot tolerate.
