Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2001. The most recent assessment (2001) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	good (>90%)	poor (40–69%)	poor

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	happe­ning now	most of popul­ation/area (50–90%)	moderate decline (10–30% over 3 gener­ations)	high
Agricultural expansion and intensification	happe­ning now	some of popul­ation/area (10–49%)	moderate decline (10–30% over 3 gener­ations)	high
Energy production and mining	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Natural system modifications	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Biological resource use	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
