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
Barnacle Goose Branta leucopsis	LC	non-breeding (2011–2015)	25,138–30,661 birds	A4i, B1i, C2
Barnacle Goose Branta leucopsis	LC	winter (2011–2015)	23,126 birds	B3
Lesser White-fronted Goose Anser erythropus	VU	non-breeding (2011–2015)	50–88 birds	A1, C1, C6
Lesser White-fronted Goose Anser erythropus	VU	winter (2011–2015)	8 birds	B2
A4iii Species group - waterbirds	n/a	non-breeding (2011–2015)	35,222–41,359 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 (2018) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	happe­ning now	whole of popul­ation/area (>90%)	no or slight decline (<1% over 3 gener­ations)	low
Transportation and service corridors	happe­ning now	few indivi­duals/small area (<10%)	no or slight decline (<1% over 3 gener­ations)	low
Energy production and mining	likely in short term (<4 years)	few indivi­duals/small area (<10%)	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	A compre­hensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species	Substantive conservation measures are being implemented, but these are not compre­hensive and are limited by resources and capacity	high

2010	Oudeland van Strijen	Natuurbeschermingswet (IV)	100
