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
Biological resource use	happe­ning now	most of popul­ation/area (50–90%)	moderate decline (10–30% over 3 gener­ations)	high
Agricultural expansion and intensification	happe­ning now	few indivi­duals/small area (<10%)	moderate decline (10–30% over 3 gener­ations)	low
Natural system modifications	happe­ning now	few indivi­duals/small area (<10%)	slow decline (1–10% over 3 gener­ations)	low
Human intrusions and disturbance	happe­ning now	few indivi­duals/small area (<10%)	no or slight decline (<1% over 3 gener­ations)	low
