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 ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species') at the site:

Species	Red List	Season (year/s of estimate)	Size	IBA criteria
Yellow-legged Pigeon Columba pallidiceps	VU	resident (-)	present	A1, A2
Crested Cuckoo-Dove Reinwardtoena crassirostris	LC	resident (-)	present	A1, A2
Mayr's Swiftlet Aerodramus orientalis	DD	- (-)	unknown	A1, A2
Roviana Rail Hypotaenidia rovianae	LC	resident (-)	present	A1, A2
Heinroth's Shearwater Puffinus heinrothi	VU	breeding (1990)	5 birds	A1, A4ii
Sanford's Sea-eagle Haliaeetus sanfordi	VU	resident (1990)	rare	A1, A2
Meek's Lorikeet Charmosyna meeki	LC	resident (1990)	abundant pairs	A1, A2
Black-faced Pitta Pitta anerythra	NT	resident (1990)	min 1 birds	A1, A2
North Melanesian Cuckooshrike Coracina welchmani	LC	resident (1990)	frequent	A2
White-winged Fantail Rhipidura cockerelli	LC	resident (1990)	uncommon	A1, A2
Kolombangara Monarch Symposiachrus browni	NT	resident (1990)	uncommon birds	A1, A2

Kolombangara White-eye Zosterops murphyi	LC	breeding (1990)	abundant birds	A2

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

State (condition of the trigger species' populations)
Species	Actual vs Reference (units)	% remaining	Result
Heinroth's Shearwater Puffinus heinrothi	5 / 5 (birds)	100	not assessed

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happe­ning now	whole of popul­ation/area (>90%)	no or slight decline (<1% over 3 gener­ations)	low
Pollution	happe­ning now	few indivi­duals/small area (<10%)	no or slight decline (<1% over 3 gener­ations)	low
