The site was identified as internationally important for bird conservation in 2000 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
Gadwall Mareca strepera	LC	winter (1998)	260–470 birds	A4i, B1i
Red Kite Milvus milvus	LC	resident (1996)	10 pairs	B3
Black Kite Milvus migrans	LC	breeding (1996)	80 pairs	B2
Grey-faced Woodpecker Picus canus	LC	resident (1996)	40–80 pairs	B2

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2000. The most recent assessment (2012) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	happe­ning now	whole of popul­ation/area (>90%)	no or slight decline (<1% over 3 gener­ations)	low
Climate change and severe weather	happe­ning now	most of popul­ation/area (50–90%)	no or slight decline (<1% over 3 gener­ations)	low
Agricultural expansion and intensification	happe­ning now	some of popul­ation/area (10–49%)	no or slight decline (<1% over 3 gener­ations)	low
Residential and commercial development	happe­ning now	some of popul­ation/area (10–49%)	no or slight decline (<1% over 3 gener­ations)	low
Biological resource use	happe­ning now	some of popul­ation/area (10–49%)	no or slight decline (<1% over 3 gener­ations)	low
Invasive and other problematic species and genes	happe­ning now	some of popul­ation/area (10–49%)	no or slight decline (<1% over 3 gener­ations)	low
Transportation and service corridors	happe­ning now	few indivi­duals/small area (<10%)	no or slight decline (<1% over 3 gener­ations)	low
Energy production and mining	likely in long term (>4 years)	few indivi­duals/small area (<10%)	no or slight decline (<1% over 3 gener­ations)	low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Some of area covered (10–49%)	No management planning has taken place	Some limited conservation initiatives are in place	low
