The site was identified as important 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 List1	Season	Year(s)	Size	IBA criteria
Nicobar Scrubfowl Megapodius nicobariensis	VU	resident	2004	present	A1, A2
Andaman Woodpigeon Columba palumboides	NT	resident	2004	present	A2
Andaman Cuckoo-Dove Macropygia rufipennis	LC	resident	2004	present	A2

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2004) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2013) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Nicobar Scrubfowl Megapodius nicobariensis	1,200	64	individuals	6	not assessed

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	good (> 90%)	moderate (70-90%)	near favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
