The site was identified as internationally important for bird conservation in 2006 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
White-headed Duck Oxyura leucocephala	EN	passage (2006)	33 birds	A1
Common Goldeneye Bucephala clangula	LC	passage (2006)	1,800 birds	A4i

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2006. The most recent assessment (2017) is shown below.

State (condition of the trigger species' habitats)

Pressure (threats to the trigger species and/or their habitats)

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Whole area (>90%) covered by appropriate conservation designation	A compre­hensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species	The conservation measures needed for the site are being compre­hensively and effectively implemented	high

Habitat	% of IBA	Habitat detail
Wetlands (inland)	80	Standing fresh water; Water-fringe vegetation
Grassland	20	Humid; Mesophile grassland & tall grass steppe; Steppes & dry calcareous
Forest	minor (<10)	Broadleaved deciduous; Mixed; Native coniferous
Shrubland	minor (<10)	Low bushes

Land use	% of IBA
rangeland/pastureland	15
