The site was identified as internationally important for bird conservation in 2000 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 List	Season (year/s of estimate)	Size	IBA criteria
Whooper Swan Cygnus cygnus	LC	winter (1994)	150 birds	C2

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2000. The most recent assessment (2010) is shown below.

State (condition of the trigger species' populations)
Species	Actual vs Reference (units)	% remaining	Result
Corncrake Crex crex	21 / 21 (pairs)	100	good
Eurasian Bittern Botaurus stellaris	2 / 2 (pairs)	100	good
Red-backed Shrike Lanius collurio	2 / 2 (pairs)	100	good

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