Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2001. The most recent assessment (2005) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Artificial/Terrestrial	good (>90%)	good (>90%)	good

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Biological resource use	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Agricultural expansion and intensification	likely in short term (<4 years)	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
Whole area (>90%) covered by appropriate conservation designation	Unknown	Some limited conservation initiatives are in place	low

Habitat	% of IBA	Habitat detail
Forest	60	Lowland forest - mixed moist evgn & semi-evgn
Savanna	20	Bushland & thicket - deciduous
Artificial/Terrestrial	15	Farmbush, fallow & ruderal land
Wetlands (inland)	5	Rivers & streams
