The site was identified as internationally important for bird conservation in 2007 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	passage (1990–2006)	120–143 birds	C2
Red-breasted Goose Branta ruficollis	VU	winter (1990–2006)	1,000–5,200 birds	C1, C2, C6
Greater White-fronted Goose Anser albifrons	LC	winter (1990–2006)	8,000–29,000 birds	C3
Smew Mergellus albellus	LC	passage (1990–2006)	45–54 birds	C2
Ferruginous Duck Aythya nyroca	NT	breeding (1990–2006)	80–120 pairs	C1, C6
Ferruginous Duck Aythya nyroca	NT	passage (1990–2006)	130–240 birds	C1
Eurasian Spoonbill Platalea leucorodia	LC	winter (1990–2006)	190–310 birds	C2
Glossy Ibis Plegadis falcinellus	LC	passage (1990–2006)	250–270 birds	C2
Dalmatian Pelican Pelecanus crispus	NT	winter (1990–2006)	120–144 birds	C1, C2, C6
Great White Pelican Pelecanus onocrotalus	LC	winter (1990–2006)	630–900 birds	C2, C6
Pygmy Cormorant Microcarbo pygmaeus	LC	winter (1990–2006)	300–400 birds	C2, C6
Pygmy Cormorant Microcarbo pygmaeus	LC	passage (1990–2006)	170–400 birds	C2
Black Tern Chlidonias niger	LC	breeding (1990–2006)	12–16 pairs	C6
A4iii Species group - waterbirds	n/a	passage (1990–2006)	32,000–60,000 birds	C4

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2016) is shown below.

State (condition of the trigger species' populations)
Species	Actual vs Reference (units)	% remaining	Result
Red-breasted Goose Branta ruficollis	4,000 / 7,000 (birds)	58	poor
Dalmatian Pelican Pelecanus crispus	70 / 100 (birds)	70	moderate

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Artificial/Terrestrial	good (>90%)	good (>90%)	good
Forest	good (>90%)	good (>90%)	good
Wetlands (inland)	good (>90%)	good (>90%)	good

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Biological resource use	happe­ning now	some of popul­ation/area (10–49%)	rapid decline (>30% over 3 gener­ations)	high
Agricultural expansion and intensification	happe­ning now	most of popul­ation/area (50–90%)	no or slight decline (<1% over 3 gener­ations)	low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Whole area (>90%) covered by appropriate conservation designation	No management plan exists, but the management planning process has begun	Substantive conservation measures are being implemented, but these are not compre­hensive and are limited by resources and capacity	medium

Habitat	% of IBA	Habitat detail
Artificial/Terrestrial	89	Arable land
Wetlands (inland)	10	Standing freshwater
Forest	1	Broadleaved deciduous woodland
