1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2004) may differ.

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%)	near favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Residential and commercial development	happening now	some of area/population (10-49%)	slow but significant deterioration	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Whole area of site (>90%) covered by appropriate conservation designation	A management plan exists but it is out of date or not comprehensive	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	medium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	% overlap with IBA
1990	Göksu Deltasi	Specially Protected Area of Marine Importance (Barcelona Convention)	100
1994	Göksu Delta	Ramsar Site, Wetland of International Importance	69
1996	Goksu Delta	SIT (Law on Protection of Cultural and Natural Assets No. 2863)	67

Habitat1	Habitat detail	% of IBA
Artificial/Terrestrial	Arable land	50
Marine Coastal/Supratidal		major (>10)
Marine Intertidal		major (>10)

1. IUCN Habitat classification.

Land use	% of IBA
agriculture	50
