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	-	present	A1, A2
White-throated Ground Dove Pampusana xanthonura	NT	resident	-	present	A1, A2
Micronesian Myzomela Myzomela rubratra	LC	resident	-	present	A2
Saipan Reed-warbler Acrocephalus hiwae	EN	resident	-	100 breeding pairs	A1, A2
Micronesian Starling Aplonis opaca	LC	resident	-	present	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	happening now	some of area/population (10-49%)	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
