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') at the site:

Species	Red List1	Season	Year(s)	Size	IBA criteria
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

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2010) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2010. The most recent assessment (2008) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happening now	whole area/population (>90%)	moderate to rapid deterioration	very high
Residential and commercial development	happening now	some of area/population (10-49%)	very rapid to severe deterioration	high
Agricultural expansion and intensification	likely in short term (within 4 years)	some of area/population (10-49%)	very rapid to severe deterioration	high
Natural system modifications	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Biological resource use	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Human intrusions and disturbance	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Pollution	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
No known threats	happening now	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
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
