Conservación

The Taveuni silktail is a restricted range species. Forest clearance for mahogany plantations and general forest clearance within its range have led to the species being listed as vulnerable in 1994; however, this was downgraded to near threatened in 2006. While its habitat is being lost, it is not yet severely fragmented. The species occurs within the Ravilevu Nature Reserve and the Bouma National Heritage Park.
