Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2003) is shown below.

Pressure (threats to the key species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happen­ing now	some of popul­ation/area (10–49%)	moderate deteri­oration (10–30% in 3 gener­ations)	high
Invasive and other problematic species and genes	happen­ing now	few individ­uals/small area (<10%)	slow deteri­oration (1–10% over 3 gener­ations)	low
Natural system modifications	happen­ing now	few individ­uals/small area (<10%)	slow deteri­oration (1–10% over 3 gener­ations)	low
Biological resource use	happen­ing now	few individ­uals/small area (<10%)	slow deteri­oration (1–10% over 3 gener­ations)	low
