Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 1994. The most recent assessment (1994) 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%)	moderate decline (10–30% over 3 gener­ations)	high
Pollution	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Transportation and service corridors	likely in short term (<4 years)	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
