The site was identified as internationally important for bird conservation in 2014 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
Erect-crested Penguin Eudyptes sclateri	EN	breeding (-)	21,373–49,999 pairs	A1, A4ii
Salvin's Albatross Thalassarche salvini	VU	breeding (1907–2009)	53,552–76,352 pairs	A1, A4ii
Southern Fulmar Fulmarus glacialoides	LC	breeding (1907–1990)	30,000–99,999 pairs	A4ii
Bounty Islands Shag Leucocarbo ranfurlyi	VU	resident (1978–1997)	344–569 pairs	A1, A4i
A4iii Species group - seabirds	n/a	- (-)	100,000-499,999 pairs	A4iii

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2014. The most recent assessment (2010) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
No known threats	happe­ning now	few indivi­duals/small area (<10%)	no or slight decline (<1% over 3 gener­ations)	low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Whole area (>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

Year	Protected Area	Designation (management category)	% coverage of IBA
1961	Bounty Islands	Nature Reserve (Ia)	56
1998	New Zealand Sub-Antarctic Islands	World Heritage Site (natural or mixed) (UA)	100
2007	Bounty Heritage	Benthic Protection Area (VI)	44

Habitat	% of IBA	Habitat detail
Marine Coastal/Supratidal	major (>10)
Marine Intertidal	major (>10)
