The site was identified as important in 2010 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
Spotted Crake Porzana porzana	LC	breeding	1995-2003	6-35 males	C6
Little Crake Zapornia parva	LC	breeding	1990-1998	50-60 males	C6
Common Crane Grus grus	LC	passage	2009	1,500 individuals	C2
Black Tern Chlidonias niger	LC	breeding	1998	80 breeding pairs	C6
Bluethroat Luscinia svecica	LC	breeding	1995-2003	6-28 breeding pairs	C6

The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (2010).

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%)	very rapid to severe deterioration	high
Biological resource use	hunting & collecting terrestrial animals - intentional use (species being assessed is the target)	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Biological resource use	hunting & collecting terrestrial animals - persecution/control	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Human intrusions and disturbance	recreational activities	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Invasive and other problematic species and genes	invasive non-native/alien species/diseases - unspecified species	happening now	whole area/population (>90%)	moderate to rapid deterioration	very high
Invasive and other problematic species and genes	problematic native species/diseases - unspecified species	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Natural system modifications	other ecosystem modifications	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
No known threats	no known threats	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low
Pollution	air-borne pollutants - type unknown/unrecorded	happening now	whole area/population (>90%)	slow but significant deterioration	high
Pollution	excess energy - noise pollution	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
Not assessed	No management plan exists but the management planning process has begun	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	low
