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'):

Smew Mergellus albellus	LC	passage	2006	10-30 individuals	C6
Common Crane Grus grus	LC	breeding	2006	7 breeding pairs	C6
Arctic Loon Gavia arctica	LC	breeding	2005	3-5 breeding pairs	C6
Eurasian Bittern Botaurus stellaris	LC	breeding	2006-2007	2-4 males	C6
Common Tern Sterna hirundo	LC	breeding	2005	29-47 breeding pairs	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
Gavia arctica	Arctic Loon	15	5	breeding pairs	34	very unfavourable
Pandion haliaetus	Osprey	10	5	breeding pairs	50	unfavourable
Haliaeetus albicilla	White-tailed Sea-eagle	1	1	breeding pairs	100	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat level 1	Threat level 2	Timing	Scope	Severity	Result
Agricultural expansion and intensification	livestock farming and ranching (includes forest grazing) - small-holder grazing, ranching or farming	likely in long term (beyond 4 years)	some of area/population (10-49%)	moderate to rapid deterioration	medium
Energy production and mining	renewable energy	happening now	whole area/population (>90%)	slow but significant deterioration	high
Human intrusions and disturbance	recreational activities	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-area designation	Management planning	Other conservation action	Result
Some of site covered (10-49%)	A management plan exists but it is out of date or not comprehensive	Some limited conservation initiatives are in place	low
