The site was identified as important in 1999 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
Masked Finfoot Heliopais personatus	CR	non-breeding	1984	present	A1
Milky Stork Mycteria cinerea	EN	breeding	1984	2-50 individuals	A1, A4i
Purple Heron Ardea purpurea	LC	breeding	1987-1998	present	A4i
Christmas Island Frigatebird Fregata andrewsi	VU	non-breeding	1987-1998	present	A1
A4iii Species group - waterbirds	n/a	breeding	1988	min 20,000 individuals	A4iii

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (1999) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 1999. The most recent assessment (2012) is shown below.

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

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Pollution	happening now	some of area/population (10-49%)	very rapid to severe deterioration	high
Natural system modifications	happening now	some of area/population (10-49%)	very rapid to severe deterioration	high
Human intrusions and disturbance	happening now	some of area/population (10-49%)	slow but significant deterioration	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Whole area of site (>90%) covered by appropriate conservation designation	A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species	The conservation measures needed for the site are being comprehensively and effectively implemented	high
