The site was identified as internationally important for bird conservation in 2012 because it was regularly supporting significant populations of the species listed below, meeting IBA criteria.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2012. The most recent assessment (2013) is shown below.

State (condition of the key species' populations)
Species	Actual vs Reference (units)	% remaining	Result
Kagu Rhynochetos jubatus	50 / 100 (unknown)	50	unfavourable

Pressure (threats to the key species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happen­ing now	whole popul­ation/area (>90%)	slow deteri­oration (1–10% over 3 gener­ations)	high
Natural system modifications	happen­ing now	some of popul­ation/area (10–49%)	rapid deteri­oration (>30% over 3 gener­ations)	high
Biological resource use	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
Little/none of site covered (<10%)	A manage­ment plan exists, but it is out of date or not compre­hensive	Some limited conservation initiatives are in place	low
