The site was identified as important 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 List1	Season	Year(s)	Size	IBA criteria
Whooper Swan Cygnus cygnus	LC	passage	1996	101-500 individuals	B1i, C2
Bean Goose Anser fabalis	LC	passage	1996	500-2,000 individuals	B1i, C3
Corncrake Crex crex	LC	breeding	1996	6-10 breeding pairs	B2, C6
Spotted Crake Porzana porzana	LC	breeding	1996	51-100 breeding pairs	B3, C2, C6
Common Crane Grus grus	LC	breeding	1996	51-100 breeding pairs	B1i, B2, C2, C6
Common Crane Grus grus	LC	passage	1996	700-1,500 individuals	B1i, C2

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2000) may differ.

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	Reference	Actual	Units	% remaining	Result
Bean Goose Anser fabalis	800	400	individuals	50	unfavourable
Spotted Crake Porzana porzana	50	7	breeding pairs	15	very unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Energy production and mining	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Pollution	happening now	majority/most of area/population (50-90%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Most of site (50-90%) covered (including the most critical parts for important bird species)	A management plan exists but it is out of date or not comprehensive	Some limited conservation initiatives are in place	low
