This IBA contains the only known site for the Vanua Levu subspecies of Long-legged Warbler (EN), and has all the other endemic birds on Vanua Levu except for the Silktail, which is restricted to another peninsula. It consists of the largest remaining important forests in Vanua Levu, and includes six Sites of National Significance as outlined in the BSAP: Delaikoro, Waisali, Tavea, Valili, Drawa and Delainacau.
This IBA supports eight of the nine subspecies endemic to Vanua Levu. A1 (globally threatened species) * Friendly Ground-dove (VU) – fairly common in some areas * [Long-legged Warbler (VU) – the only record of the Vanua Levu subspecies T. r. clunei was from here in 1974; probably still occurs] * Black-faced Shrikebill (VU) – rare A2 (restricted-range species) 22 species (out of 24 on Vanua Levu), including two of the three endemic to Vanua Levu and Taveuni.
Non-bird biodiversity: Limited surveys have been undertaken in Waisali and Drawa only. Waisali is the only known site for the Fijian Ground Frog (EN) on mainland Fiji (Viti Levu and Vanua Levu) despite the presence of mongoose. Waisali also supports the Fijian Tree Frog (NT) and at least four species of reptile including the Turquoise Tree Skink which is known only from one other specimen. The BSAP technical botanical report identified six Vanua Levu sites of high botanical biodiversity, four of which are part of this IBA (Waisali, Mt Dikeva, Mt Delainacau and Mt Kasi). Botanical surveys at Drawa showed that 51% of flora species are native, 47% are endemic to Fiji and 10 species are threatened within Fiji.
