The site was identified as important in 2000 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
Purple Heron Ardea purpurea	LC	breeding	1994	20-80 breeding pairs	B2
Common Tern Sterna hirundo	LC	breeding	1994	600-2,000 breeding pairs	B1i
Sandwich Tern Thalasseus sandvicensis	LC	breeding	1994	500-1,000 breeding pairs	A4i, B1i, B2

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2000) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2000. The most recent assessment (2017) is shown below.
