The site was identified as important in 2005 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	passage	2005	6,000-18,000 individuals	A4i
Demoiselle Crane Anthropoides virgo	LC	passage	2005	500-4,000 individuals	A4i
A4iii Species group - waterbirds	n/a	passage	2005	20,000-49,999 individuals	A4iii

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2005) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2005. The most recent assessment (2017) is shown below.
