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
Greylag Goose Anser anser	LC	breeding (1992)	130 pairs	B1i
Common Teal Anas crecca	LC	passage (1992)	25,000 birds	A4i, B1i
Glossy Ibis Plegadis falcinellus	LC	breeding (1993)	120–1,500 pairs	A4i, B1i, B2
Black-crowned Night Heron Nycticorax nycticorax	LC	breeding (1993)	1,000–2,500 pairs	A4i, B1i, B2
Purple Heron Ardea purpurea	LC	breeding (1993)	100–150 pairs	B2
Great White Egret Ardea alba	LC	breeding (1992)	110–330 pairs	A4i, B1i
Great Cormorant Phalacrocorax carbo	LC	breeding (1993)	2,000–2,500 pairs	A4i, B1i
A4iii Species group - waterbirds	n/a	passage (1992)	20,000-49,999 birds	A4iii

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2000. The most recent assessment (2017) is shown below.

State (condition of the trigger species' populations)
Species	Actual vs Reference (units)	% remaining	Result
Greylag Goose Anser anser	130 / 130 (pairs)	100	good
Anas crecca	3,000 / 25,000 (pairs)	12	very poor
Eurasian Coot Fulica atra	2,000 / 2,000 (pairs)	100	good
Glossy Ibis Plegadis falcinellus	310 / 810 (pairs)	39	very poor
Black-crowned Night Heron Nycticorax nycticorax	200 / 1,750 (pairs)	12	very poor
Purple Heron Ardea purpurea	100 / 125 (pairs)	80	moderate
Great White Egret Ardea alba	110 / 220 (pairs)	50	poor
Great Cormorant Phalacrocorax carbo	2,000 / 2,500 (pairs)	80	moderate

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Energy production and mining	happe­ning now	whole of popul­ation/area (>90%)	rapid decline (>30% over 3 gener­ations)	very high
Climate change and severe weather	happe­ning now	whole of popul­ation/area (>90%)	moderate decline (10–30% over 3 gener­ations)	very high
Natural system modifications	happe­ning now	most of popul­ation/area (50–90%)	rapid decline (>30% over 3 gener­ations)	very high
Human intrusions and disturbance	likely in long term (>4 years)	most of popul­ation/area (50–90%)	moderate decline (10–30% over 3 gener­ations)	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Some of area covered (10–49%)	A management plan exists, but it is out of date or not compre­hensive	Very little or no conservation action taking place	low
