The site was identified as important 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 List1	Season	Year(s)	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

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2012) may differ.

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	Reference	Actual	Units	% remaining	Result
Heinroth's Shearwater Puffinus heinrothi	5	5	individuals	100	not assessed

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Climate change and severe weather	likely in long term (beyond 4 years)	whole area/population (>90%)	no or imperceptible deterioration	low
Invasive and other problematic species and genes	happening now	whole area/population (>90%)	no or imperceptible deterioration	low
Pollution	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low
Biological resource use	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Little/none of site covered (<10%)	No management planning has taken place	Very little or no conservation action taking place	negligible
