The site was identified as important in 2007 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
Little Tern Sternula albifrons	LC	breeding	2000	309 breeding pairs	A4i, B1i, B2, C2
Little Tern Sternula albifrons	LC	breeding	2006	369 breeding pairs	A4i, B1i, B2, C2

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2007) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2007) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Little Tern Sternula albifrons	250	369	breeding pairs	100	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Natural system modifications	likely in short term (within 4 years)	small area/few individuals (<10%)	slow but significant deterioration	low

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	No management plan exists but the management planning process has begun	The conservation measures needed for the site are being comprehensively and effectively implemented	medium

Year	Protected Area	Designation	% overlap with IBA
