The site was identified as important in 2016 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species'):

Species	Current IUCN Red List Category	Season	Year(s)	Population estimate at site	IBA criteria met
Barnacle Goose Branta leucopsis	LC	breeding	2011-2015	475-650 breeding pairs	B3, C2, C6
Eurasian Wigeon Mareca penelope	LC	non-breeding	2011-2015	17,103-22,420 individuals	B1i, C3
A4iii Species group - waterbirds	n/a	non-breeding	2011-2015	26,249-32,362 individuals	A4iii, C4

The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (2016).

Pressure (threats to the trigger species and/or their habitats)
Threat level 1	Threat level 2	Timing	Scope	Severity	Result
Human intrusions and disturbance	recreational activities	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Invasive and other problematic species and genes	problematic native species/diseases - unspecified species	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Transportation and service corridors	flight paths	happening now	some of area/population (10-49%)	no or imperceptible deterioration	low
Transportation and service corridors	utility & service lines	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected-area designation	Management planning	Other conservation action	Result
Whole area of site (>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
