Summary This site holds significant numbers of Long-legged warbler, and has contained all the other threatened and endemic species on Viti Levu, although Red-throated Lorikeet has not been seen for a number of years.
Site description The Rairaimatuku Highlands forms part of Viti Levu's large central plateau. Some of the area receives partial protection as a watershed for Fiji’s largest hydro-electric dams.
Key Biodiversity The montane forests from Rairaimatuku to the Greater Tomaniivi IBA are the best hope for survival of Red-throated Lorikeet but ongoing surveys are yet to confirm its current status. The species was reportedly "well known to everyone in Nadrau" in 1979 and there are a few records in the Nadrau area until 1993. The IBA is nationally important for the numbers of Pacific Black Duck on Monasavu reservoir, where a maximum of 120 have been seen, and Peregrine Falcons probably breed. A1 Globally threatened species * [Red-throated Lorikeet (CR) – last known site (last sighting in 1993); may still occur] * Long-legged Warbler (EN) – one of only two known populations; at least two pairs * Friendly Ground-dove (VU) – uncommon * Pink-billed Parrotfinch (VU) – uncommon * Black-faced Shrikebill (VU) – fairly common * Masked Shining Parrot (NT) – uncommon at this altitude A2 Restricted-range species 24 species (out of 25 known from Viti Levu), including all three endemic to Viti Levu.
Non-bird biodiversity: The Rairaimatuku area is the only known site for the endemic Montane Tree Skink although this species is likely to occur elsewhere in montane Viti Levu. Other endemic species include Fijian Tree Frog (NT) and Green Tree Skink, but the plants and other biodiversity are poorly known.

Land ownership The forested watershed is owned by local land-owners but is not leased or managed by FEA, even though the FEA relies on the catchment for an uninterrupted supply of water for its hydropower. The land tenure is mostly Native Lands except for three Crown Lands totalling about 1,490 ha.
