Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2009. The most recent assessment (2008) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	happe­ning now	most of popul­ation/area (50–90%)	slow decline (1–10% over 3 gener­ations)	high
Invasive and other problematic species and genes	happe­ning now	most of popul­ation/area (50–90%)	slow decline (1–10% over 3 gener­ations)	high
