The site was identified as internationally important for bird conservation in 2010 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
Shy Ground Dove Pampusana stairi	LC	resident (2010)	50-249 birds	A1, A2
Tooth-billed Pigeon Didunculus strigirostris	CR	resident (-)	present	A1, A2
Many-coloured Fruit-dove Ptilinopus perousii	LC	resident (-)	present	A2
Samoan Fruit-dove Ptilinopus fasciatus	LC	resident (-)	present	A2
Flat-billed Kingfisher Todiramphus recurvirostris	LC	resident (-)	present	A2
Blue-crowned Lorikeet Vini australis	LC	resident (-)	present	A2
Polynesian Wattled Honeyeater Foulehaio carunculatus	LC	resident (-)	present	A2
Cardinal Myzomela Myzomela cardinalis	LC	resident (-)	present	A2
Samoan Whistler Pachycephala flavifrons	LC	resident (-)	present	A2
Polynesian Triller Lalage maculosa	LC	resident (-)	present	A2
Samoan Fantail Rhipidura nebulosa	LC	resident (-)	present	A2
Samoan Flycatcher Myiagra albiventris	LC	resident (-)	present	A1, A2

Samoan Starling Aplonis atrifusca	LC	resident (-)	present	A2
Red-headed Parrotfinch Erythrura cyaneovirens	LC	resident (-)	present	A2

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2010. The most recent assessment (2010) 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 long term (>4 years)	whole of popul­ation/area (>90%)	slow decline (1–10% over 3 gener­ations)	medium
Climate change and severe weather	likely in long term (>4 years)	most of popul­ation/area (50–90%)	moderate decline (10–30% over 3 gener­ations)	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Whole area (>90%) covered by appropriate conservation designation	No management plan exists, but the management planning process has begun	Substantive conservation measures are being implemented, but these are not compre­hensive and are limited by resources and capacity	medium

Year	Protected Area	Designation (management category)	% coverage of IBA
-	Nu'utele Islands	Other Area (-)	4
1999	Aleipata Marine Protected Area	Project (VI)	100
