The site was identified as internationally important for bird conservation in 2016 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
Gadwall Mareca strepera	LC	non-breeding (2011–2015)	2,531–3,701 birds	B1i, C3
Common Ringed Plover Charadrius hiaticula	LC	breeding (2011–2015)	17 pairs	B3
Caspian Tern Hydroprogne caspia	LC	non-breeding (2011–2015)	3–7 birds	C6
A4iii Species group - waterbirds	n/a	non-breeding (2011–2015)	min 19,387 birds	A4iii, C4

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2016. The most recent assessment (2017) is shown below.

State (condition of the trigger species' populations)
Species	Actual vs Reference (units)	% remaining	Result
Gadwall Mareca strepera	2,531 / 160 (birds)	100	good
Caspian Tern Hydroprogne caspia	3 / 10 (birds)	30	very poor

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90%) covered by appropriate conservation designation	A management plan exists, but it is out of date or not compre­hensive	Unknown	low

Year	Protected Area	Designation (management category)	% coverage of IBA
2011	Ketelmeer & Vossemeer	Natuurbeschermingswet (IV)	100

Habitat	% of IBA	Habitat detail
Wetlands (inland)	100	Standing freshwater

Land use	% of IBA
