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
Sandwich Tern Thalasseus sandvicensis	LC	winter	1994	39 individuals	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
Charadrius alexandrinus	2	2	breeding pairs	100	favourable

Pressure (threats to the trigger species and/or their habitats)

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Some of site covered (10-49%)	A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	medium
