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)	444–536 pairs	C2
Gadwall Mareca strepera	LC	non-breeding (2011–2015)	1,782–2,449 birds	B1i, C3
Eurasian Wigeon Mareca penelope	LC	non-breeding (2011–2015)	44,338–56,500 birds	A4i, B1i, C3
Eurasian Wigeon Mareca penelope	LC	winter (2011–2015)	35,907 birds	B3
A4iii Species group - waterbirds	n/a	non-breeding (2011–2015)	53,287–61,823 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	1,782 / 70 (birds)	100	good
Eurasian Wigeon Mareca penelope	44,338 / 7,500 (birds)	100	good
