The site was identified as internationally important for bird conservation in 2002 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 List	Season (year/s of estimate)	Size	IBA criteria
Common Little Bittern Ixobrychus minutus	LC	breeding (2001)	8 pairs	C6
Purple Heron Ardea purpurea	LC	breeding (2001)	1–2 pairs	C6
Black Kite Milvus migrans	LC	breeding (1996)	common	C6

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2002. The most recent assessment (2005) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Transportation and service corridors	happe­ning now	few indivi­duals/small area (<10%)	rapid decline (>30% over 3 gener­ations)	low
