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
Common Little Bittern Ixobrychus minutus	LC	breeding	2007-2009	12-18 breeding pairs	C6
Black-crowned Night Heron Nycticorax nycticorax	LC	breeding	2008	113-120 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 (2011) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Natural system modifications	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Energy production and mining	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Biological resource use	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Pollution	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Climate change and severe weather	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Human intrusions and disturbance	happening now	whole area/population (>90%)	moderate to rapid deterioration	very high
Transportation and service corridors	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Invasive and other problematic species and genes	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Residential and commercial development	likely in short term (within 4 years)	some of area/population (10-49%)	slow but significant deterioration	medium
No known threats	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low
