Site description Sovi Basin is the largest (proposed) protected area in Fiji. It is unique in the Pacific islands in being a large uninhabited basin with a pristine watershed of lowland rainforest. It supports populations of most of Viti Levu’s birds including Long-legged Warbler (EN) and relatively large numbers of Pink-billed Parrotfinches (VU).

Other biodiversity The endemic Fijian Burrowing Snake (VU) is known historically from Sovi and several other endemic reptiles occur including Green Tree Skink and Fijian Copper-headed Skink. The Fijian Tree Frog (NT) also occurs. Recent PABITRA surveys suggest that the basin supports about 680 species of vascular plants, one third of Fiji’s total. This includes large numbers of Schefflera euthytrica (DD) in a very rare lowland rainforest formation on plains around creeks dominated by Verbenaceae trees.
