Summary This IBA covers all of Rotuma as this small island group, situated 465 km north of the main Fijian islands, is the only location for the Rotuman Myzomela.

Site description The IBA consists of the main island of Rotuma and associated small satellite islets.  The main island is a shield volcano divided into two parts by a sandy isthmus, with coastal terraces, a central plateau (30-60m asl) and steep volcanic cones.

Key Biodiversity The total world populations of the Rotuman Myzomela and the Rotuman subspecies of Polynesian Starling A. t. rotumae and Lesser Shrikebill C. v.wiglesworthi occur in this IBA. Rotuma also supports isolated outlying populations of Crimson-crowned Fruit-dove and Polynesian Triller. The offshore islets of Ha’atana, Hofliua and Hatawa have nationally significant seabird colonies. A1 (globally threatened species) * [Bristle-thighed Curlew (VU) – non-breeding visitor in unknown but probably very small numbers] * Rotuman Myzomela (VU) – common to abundant across the island A2 (restricted-range species) Five species (compared to 35 on the main Fiji group).

Non-bird biodiversity: Rotuma has one other endemic vertebrate, the Rotuman Forest Gecko, and two other lizards endemic to Fiji, the Green Tree Skink and Barred Tree Skink.

Land ownership The island’s physical isolation has led to a powerful and relatively traditional local government. The land is Native Tenure administered through a specific Act.
