Site description
Gau is the fifth largest island in Fiji. Mt Delaco, the island’s highest peak, rises to 738 m above sealevel while Delacoboni is 705m asl.  The land is rugged dominated by the summits in the north and a main ridge running south (Watling 1986).  .  

Key biodiversity
There are only a handful of records of Fiji Petrels on land in the world, all of single birds attracted to village lights on Gau. Tens or hundreds of pairs of Collared Petrel constitute the only known regular breeding site of this species in Fiji. Two subspecies, Island Thrush T. p. hades and Golden Whistler P. p. vitiensis, are endemic to Gau. There are13 restricted range species in the forests (out of 36 in Fiji). A4ii Congregatory Both seabird species * Fiji Petrel – meets the threshold of >1 pair * Collared Petrel – meets the threshold of >10 pairs

Non-bird biodiversity: Gau is free of mongoose and supports good numbers of amphibians and reptiles including the Fijian Ground Frog (EN) and Banded Iguana (EN). Preliminary studies suggest that it has high numbers of endemic plants.
