Summary The IBA supports >1% of the global populations of Brown Booby and Roseate Tern. The breeding colony of Brown Booby is possibly the largest anywhere in the world.
Site description The IBA consists of the four islands - West Island, Middle Island, East Island and Sandy Island- that comprise the Lacepede Islands, these being located about 120 km north of Broome, 55 km west of Beagle Bay and about 25 km off the coast of northern Western Australia. The Lacepede Islands receive, on average, about 750 mm of rainfall per year. The islands are formed of coarse sand and coral rubble deposited atop a large platform reef. The islands are treeless but support scattered, low vegetation.
