The site was identified as important in 2011 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
Band-rumped Storm-petrel Hydrobates castro	LC	breeding	2007	min 100 breeding pairs	B1ii, B2, C2, C6
Audubon's Shearwater Puffinus lherminieri	LC	breeding	2007	min 5 breeding pairs	B2, C6
Bulwer's Petrel Bulweria bulwerii	LC	breeding	2007	300-400 breeding pairs	B1ii, B2, C2, C6

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2011) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2011. The most recent assessment (2008) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Hydrobates castro	100	100	individuals	100	favourable
Puffinus assimilis	20	20	individuals	100	favourable
Bulwer's Petrel Bulweria bulwerii	300	300	individuals	100	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	happening now	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
Whole area of site (>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
