The site was identified as internationally important for bird conservation in 2008 because it was regularly supporting significant populations of the species listed below, meeting IBA criteria.

Populations meeting IBA criteria ('key species') at the site:

Species	Red List	Season (year/s of estimate)	Size	IBA criteria
Micronesian Scrubfowl Megapodius laperouse	NT	resident (2005)	present	A1, A2
Palau Ground Dove Pampusana canifrons	EN	resident (2005)	present	A2
Micronesian Imperial-pigeon Ducula oceanica	VU	resident (2005)	present	A2
Palau Fruit-dove Ptilinopus pelewensis	LC	resident (2005)	present	A2
Palau Swiftlet Aerodramus pelewensis	LC	resident (2005)	present	A2

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2008. The most recent assessment (2018) is shown below.

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

Pressure (threats to the key species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	likely in long term (beyond 4 years)	some of popul­ation/area (10–49%)	slow deteri­oration (1–10% over 3 gener­ations)	medium
Invasive and other problematic species and genes	likely in short term (within 4 years)	some of popul­ation/area (10–49%)	no deteri­oration (<1% over 3 gener­ations)	low

Response (conservation actions taken for the key species and/or their habitats)
Designation	Planning	Action	Result
Some of site covered (10–49%)	A manage­ment plan exists, but it is out of date or not compre­hensive	Some limited conservation initiatives are in place	low

Year	Protected Area	Designation (management category)	% coverage of IBA
-	Ngermeskang	Bird Sanctuary (V)	3
1994	Ngaremeduu	Conservation Area (V)	13
2005	Ngaremeduu	UNESCO-MAB Biosphere Reserve (UA)	100

Habitat	% of IBA	Habitat detail
Forest	major (>10)	Lowland forest - mixed swamp; Mangrove forest (tropical)

Land use	% of IBA
other	minor (<10)
nature conservation and research	minor (<10)
