Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2016) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Marine Coastal/Supratidal	good (>90%)	moderate (70–90%)	moderate

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	happe­ning now	most of popul­ation/area (50–90%)	moderate decline (10–30% over 3 gener­ations)	high
Residential and commercial development	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Whole area (>90%) covered by appropriate conservation designation	A management plan exists, but it is out of date or not compre­hensive	Substantive conservation measures are being implemented, but these are not compre­hensive and are limited by resources and capacity	medium

Year	Protected Area	Designation (management category)	% coverage of IBA
1990	Göksu Deltasi	Specially Protected Area of Marine Importance (Barcelona Convention) (IV)	100
1996	Goksu Delta	SIT (Law on Protection of Cultural and Natural Assets No. 2863) (-)	67

Habitat	% of IBA	Habitat detail
Artificial/Terrestrial	50	Arable land
Marine Coastal/Supratidal	major (>10)
Marine Intertidal	major (>10)

Land use	% of IBA
agriculture	50
not utilised	20
