The site was identified as important in 2010 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
Common Crane Grus grus	LC	passage	2004-2009	950-3,000 individuals	C2
Common Little Bittern Ixobrychus minutus	LC	breeding	2004-2008	8-15 breeding pairs	C6

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2010) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2010. The most recent assessment (2010) is shown below.

Pollution	likely in short term (within 4 years)	majority/most of area/population (50-90%)	moderate to rapid deterioration	high

Response (conservation actions taken for the trigger species and/or their habitats)
