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	breeding (2011–2015)	475–650 pairs	B3, C2, C6
Eurasian Wigeon Mareca penelope	LC	non-breeding (2011–2015)	17,103–22,420 birds	B1i, C3
A4iii Species group - waterbirds	n/a	non-breeding (2011–2015)	26,249–32,362 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
Invasive and other problematic species and genes	happe­ning now	most of popul­ation/area (50–90%)	moderate decline (10–30% over 3 gener­ations)	high
Human intrusions and disturbance	happe­ning now	most of popul­ation/area (50–90%)	slow decline (1–10% over 3 gener­ations)	high
Transportation and service corridors	happe­ning now	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	Very little or no conservation action taking place	medium
