The site was identified as important in 2004 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species') at the site:

Species	Red List1	Season	Year(s)	Size	IBA criteria
Masked Finfoot Heliopais personatus	CR	non-breeding	2004	present	A1, A3
Chinese Egret Egretta eulophotes	VU	non-breeding	2004	present	A1
Spotted Greenshank Tringa guttifer	EN	winter	2004	present	A1, A4i
Common Tern Sterna hirundo	LC	winter	2004	present	A4i
Lesser Crested Tern Thalasseus bengalensis	LC	winter	2004	present	A4i

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 (2013) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Residential and commercial development	likely in short term (within 4 years)	some of area/population (10-49%)	very rapid to severe deterioration	high
Transportation and service corridors	likely in short term (within 4 years)	some of area/population (10-49%)	very rapid to severe deterioration	high
Pollution	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Human intrusions and disturbance	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Natural system modifications	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90%) covered by appropriate conservation designation	A management plan exists but it is out of date or not comprehensive	The conservation measures needed for the site are being comprehensively and effectively implemented	high

Year	Protected Area	Designation	% overlap with IBA
2001	Krabi Estuary	Ramsar Site, Wetland of International Importance	100

Habitat1	Habitat detail	% of IBA
Forest	Mangrove forest (tropical)	89
Marine Intertidal		11
Artificial/Terrestrial		minor (<10)
Marine Coastal/Supratidal		minor (<10)
Marine Neritic		minor (<10)
