The site was identified as important in 2009 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
Red-crested Pochard Netta rufina	LC	breeding	1996-2006	250-300 breeding pairs	A4i, B1i
Common Pochard Aythya ferina	VU	breeding	2004-2006	1,000 breeding pairs	B2
Glossy Ibis Plegadis falcinellus	LC	breeding	1996-2006	80-120 breeding pairs	B2
Black-winged Pratincole Glareola nordmanni	NT	breeding	1996-2006	10-11 breeding pairs	A1
Slender-billed Gull Larus genei	LC	passage	2006	3,000 individuals	A4i, B1i
Whiskered Tern Chlidonias hybrida	LC	breeding	1996-2006	150-250 breeding pairs	B2

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2009) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2009. The most recent assessment (2006) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Himantopus himantopus	30	30	breeding pairs	100	favourable
Black-winged Pratincole Glareola nordmanni	11	10	breeding pairs	91	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Biological resource use	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Natural system modifications	happening now	some of area/population (10-49%)	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	Very little or no conservation action taking place	negligible
