The site was identified as internationally important for bird conservation in 2004 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
Andaman Woodpigeon Columba palumboides	NT	resident (2004)	present	A2
Andaman Cuckoo-Dove Macropygia rufipennis	LC	resident (2004)	present	A2
Andaman Crake Rallina canningi	LC	resident (2004)	present	A2
Andaman Boobook Ninox affinis	LC	resident (2004)	present	A2
Andaman Serpent-eagle Spilornis elgini	VU	resident (2004)	present	A2
Andaman Woodpecker Dryocopus hodgei	VU	resident (2004)	present	A2
Andaman Drongo Dicrurus andamanensis	LC	resident (2004)	present	A2
Andaman Treepie Dendrocitta bayleii	VU	resident (2004)	present	A2
White-headed Starling Sturnia erythropygia	LC	resident (2004)	present	A2

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.

Threat	Timing	Scope	Severity	Result
Biological resource use	happe­ning now	few indivi­duals/small area (<10%)	slow decline (1–10% over 3 gener­ations)	low
