Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2001. The most recent assessment (2017) is shown below.

State (condition of the trigger species' populations)
Species	Actual vs Reference (units)	% remaining	Result
Hartlaub's Duck Pteronetta hartlaubii	30 / 30 (pairs)	100	good
Psittacus erithacus	300 / 300 (adults)	100	good

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
Pollution	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%)	slow decline (1–10% over 3 gener­ations)	medium
Climate change and severe weather	likely in short term (<4 years)	most of popul­ation/area (50–90%)	slow decline (1–10% over 3 gener­ations)	medium
Residential and commercial development	likely in short term (<4 years)	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Transportation and service corridors	past (and unlikely to return) and no longer limiting	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	low

Response (conservation actions taken for the trigger species and/or their habitats)
