The site was identified as internationally important for bird conservation in 2013 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 List	Season (year/s of estimate)	Size	IBA criteria
Goliath Heron Ardea goliath	LC	non-breeding (1993)	1 birds	B2
Pink-backed Pelican Pelecanus rufescens	LC	resident (1993)	12 birds	B2
Crab-plover Dromas ardeola	LC	non-breeding (1993)	22–34 birds	B3
White-eyed Gull Larus leucophthalmus	LC	non-breeding (1993)	10–30 birds	A1, B2
Caspian Tern Hydroprogne caspia	LC	passage (1993)	100 birds	B1i
White-cheeked Tern Sterna repressa	LC	non-breeding (1993)	125 birds	B3

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2013. The most recent assessment (2013) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	likely in short term (<4 years)	whole of popul­ation/area (>90%)	moderate decline (10–30% over 3 gener­ations)	high

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Little/none of area covered (<10%)	No management planning has taken place	Not assessed	very low

Habitat	% of IBA	Habitat detail
Desert	major (>10)
Marine Intertidal	major (>10)
Marine Neritic	major (>10)
Forest	minor (<10)

Land use	% of IBA
fisheries/aquaculture	major (>10)
rangeland/pastureland	major (>10)
urban/industrial/transport	minor (<10)
agriculture	minor (<10)
