Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2007) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	happe­ning now	some of popul­ation/area (10–49%)	moderate decline (10–30% over 3 gener­ations)	high
Invasive and other problematic species and genes	happe­ning now	few indivi­duals/small area (<10%)	rapid decline (>30% over 3 gener­ations)	low

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