Site description The Tofua IBA comprises the whole island of Tofua, a 46.6 sq. km active volcanic island which retains the largest area of biodiversity rich moist tropical forest in Tonga. The island has seven of the ten central Polynesian restricted range species, and is particularly important for the Tongan populations of the Fiji shrikebill Clytorhynchus vitiensis and the blue-crowned lorikeet Vini australis. The island is inhabited and the on-going clearing of forest for kava plantations is a significant conservation concern as is the presence of feral pigs. Very little is documented on the avifauna and biodiversity of Tofua, for instance there are no seabird records from the island.
