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	24-40 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 (2010) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Ixobrychus minutus	40	40	breeding pairs	100	favourable

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Wetlands (inland)	moderate (70-90%)	moderate (70-90%)	unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Biological resource use	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Human intrusions and disturbance	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Pollution	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Residential and commercial development	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Energy production and mining	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Invasive and other problematic species and genes	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Climate change and severe weather	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Agricultural expansion and intensification	happening now	small area/few individuals (<10%)	moderate to rapid deterioration	low
Natural system modifications	happening now	small area/few individuals (<10%)	moderate to rapid deterioration	low
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
Some of site covered (10-49%)	No management planning has taken place	Very little or no conservation action taking place	negligible
