The site was identified as important in 1994 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species'):

Species	Current IUCN Red List Category	Season	Year(s)	Population estimate at site	IBA criteria met
Western Reef-egret Egretta gularis	LC	passage	1991	200 individuals	B1i
Western Reef-egret Egretta gularis	LC	resident	1991	10-100 breeding pairs	B1i
Socotra Cormorant Phalacrocorax nigrogularis	VU	breeding	1992	200,000-300,000 adults	A1, A4i, B1i, B2
Saunders's Tern Sternula saundersi	LC	breeding	1991	10-100 breeding pairs	B3
White-cheeked Tern Sterna repressa	LC	breeding	1991	10-100 breeding pairs	B3
White-cheeked Tern Sterna repressa	LC	passage	1991	2,000 individuals	B3
Sooty Falcon Falco concolor	VU	breeding	1991	13 breeding pairs	B2
A4iii Species group - waterbirds	n/a	breeding	1992	200,000-300,000 adults	A4iii

The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (1994).
