The site was identified as important in 2007 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
Micronesian Scrubfowl Megapodius laperouse	NT	resident	1982	present	A1, A2
White-throated Ground Dove Pampusana xanthonura	NT	resident	1982	50-249 individuals	A1, A2
Mariana Fruit-dove Ptilinopus roseicapilla	NT	resident	1982	50-249 individuals	A1, A2
Mariana Swiftlet Aerodramus bartschi	VU	resident	1982	2,500-9,999 individuals	A1, A2

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2007) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2007) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	likely in short term (within 4 years)	majority/most of area/population (50-90%)	slow but significant deterioration	medium
Residential and commercial development	likely in short term (within 4 years)	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
Not assessed	Not assessed	Not assessed	not assessed

Year	Protected Area	Designation	% overlap with IBA
-	Kagman	Conservation Area	5
-	Susupe	Wetland	<1
2000	Forbidden Island	Marine Sanctuary	1
2000	Laulau Bay Sea Cucumber	Reserve	1
