Site description Three islands up to 36 m high in the south-east Arabian Gulf, 35 km north of Abu Dhabi mainland and 70 km west of Sir Bani Yas island. North Yasat is uninhabited. The islands are fringed by coral reefs.

Key Biodiversity See box for key species. This is a very important seabird breeding site, judging by the only two surveys in May 1990 and March-April 1993. Other breeding species include Egretta gularis (7 pairs), Pandion haliaetus (17-20 pairs), Charadrius alexandrinus, Sterna anaethetus ('large colonies' were found forming on all three islands in May 1990, and a group of 250 birds was on North Yasat in April 1993), Eremopterix nigriceps and Alaemon alaudipes.

Non-bird biodiversity: Mammals: dolphins Tursiops truncatus and Sousa chinensis (K) occur, and sea-turtles Chelonia mydas (E) probably nest.
