The site was identified as internationally important for bird conservation in 2004 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2003) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happe­ning now	most of popul­ation/area (50–90%)	slow decline (1–10% over 3 gener­ations)	high
Natural system modifications	happe­ning now	few indivi­duals/small area (<10%)	slow decline (1–10% over 3 gener­ations)	low
Biological resource use	happe­ning now	few indivi­duals/small area (<10%)	slow decline (1–10% over 3 gener­ations)	low
Transportation and service corridors	likely in long term (>4 years)	few indivi­duals/small area (<10%)	moderate decline (10–30% over 3 gener­ations)	low
