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') at the site:

Species	Red List1	Season	Year(s)	Size	IBA criteria
Barnacle Goose Branta leucopsis	LC	non-breeding	2011-2015	24,615-31,650 individuals	A4i, B1i, C2
Greater White-fronted Goose Anser albifrons	LC	non-breeding	2011-2015	25,351-42,555 individuals	B1i, C3
White Stork Ciconia ciconia	LC	breeding	2011-2015	17-39 breeding pairs	C6
Eurasian Bittern Botaurus stellaris	LC	breeding	2011-2015	11-13 breeding pairs	C6
Black-tailed Godwit Limosa limosa	NT	non-breeding	2011-2015	3,632-5,400 individuals	B1i, C3
Savi's Warbler Locustella luscinioides	LC	breeding	2011-2015	77 breeding pairs	B3
A4iii Species group - waterbirds	n/a	non-breeding	2011-2015	22,915-37,173 individuals	A4iii, C4

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2016) may differ.

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	some of area/population (10-49%)	moderate to rapid deterioration	high
Residential and commercial development	likely in short term (within 4 years)	small area/few individuals (<10%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other 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
