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
Ruddy Shelduck Tadorna ferruginea	LC	non-breeding	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 (2012) is shown below.

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

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
No known threats	past (and unlikely to return) and no longer limiting	small area/few individuals (<10%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Little/none of site covered (<10%)	No management planning has taken place	Unknown	negligible

Habitat1	Habitat detail	% of IBA
Marine Coastal/Supratidal		major (>10)
Marine Intertidal		major (>10)
Artificial/Aquatic & Marine	Saltpans	minor (<10)
Artificial/Terrestrial		minor (<10)
