Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2008) is shown below.

Pressure (threats to the key species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Biological resource use	happen­ing now	some of popul­ation/area (10–49%)	slow deteri­oration (1–10% over 3 gener­ations)	medium
Agricultural expansion and intensification	happen­ing now	some of popul­ation/area (10–49%)	slow deteri­oration (1–10% over 3 gener­ations)	medium

Response (conservation actions taken for the key species and/or their habitats)
Designation	Planning	Action	Result
Whole area of site (>90%) covered by appropriate conservation designation	No manage­ment plan exists, but the manage­ment planning process has begun	Substantive conservation measures are being implemented, but these are not comprehensive and are limited by resources and capacity	medium
