Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2008) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	moderate (70–90%)	moderate (70–90%)	poor

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Transportation and service corridors	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Biological resource use	happe­ning now	most of popul­ation/area (50–90%)	no or slight decline (<1% over 3 gener­ations)	low
Agricultural expansion and intensification	happe­ning now	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
Whole area (>90%) covered by appropriate conservation designation	A management plan exists, but it is out of date or not compre­hensive	Substantive conservation measures are being implemented, but these are not compre­hensive and are limited by resources and capacity	medium
