The site was identified as important in 2000 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
Whooper Swan Cygnus cygnus	LC	passage	1996	101-500 individuals	B1i, C2
Tundra Swan Cygnus columbianus	LC	passage	1996	51-100 individuals	A4i, B1i, C2
Caspian Tern Hydroprogne caspia	LC	passage	1996	11-50 individuals	B1i, C2

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2000) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2000. The most recent assessment (2010) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Whooper Swan Cygnus cygnus	200	100	individuals	50	unfavourable
Tundra Swan Cygnus columbianus	50	11	individuals	22	very unfavourable
Caspian Tern Hydroprogne caspia	11	2	individuals	19	very unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Pollution	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Human intrusions and disturbance	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high

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90%) covered by appropriate conservation designation	A management plan exists but it is out of date or not comprehensive	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	medium
