The site was identified as important in 2007 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
Smew Mergellus albellus	LC	winter	2002	35-155 individuals	C2, C6
Tufted Duck Aythya fuligula	LC	winter	1999	2,000-15,135 individuals	B1i, C3
Caspian Tern Hydroprogne caspia	LC	breeding	2006	75 breeding pairs	A4i, B1i, C2, C6
White-tailed Sea-eagle Haliaeetus albicilla	LC	winter	2006	10-35 individuals	A1, C1, C6

The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (2007).

State (condition of the trigger species' populations)
Scientific name	Common name	Reference population	Actual population	Units	% of population remaining	Result
Hydroprogne caspia	Caspian Tern	125	75	breeding pairs	60	unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat level 1	Threat level 2	Timing	Scope	Severity	Result
Agricultural expansion and intensification	wood and pulp plantations (includes afforestation) - small-holder plantations	likely in short term (within 4 years)	some of area/population (10-49%)	moderate to rapid deterioration	medium
Human intrusions and disturbance	recreational activities	likely in short term (within 4 years)	majority/most of area/population (50-90%)	slow but significant deterioration	medium
Residential and commercial development	commercial and industrial development	likely in long term (beyond 4 years)	some of area/population (10-49%)	slow but significant deterioration	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Protected-area designation	Management planning	Other conservation action	Result
Some of site covered (10-49%)	A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	medium
