Summary The IBA supports the entire known global breeding population of the critically endangered Orange-bellied Parrot. The IBA also supports populations of 11 restricted-range (endemic) species, two biome-restricted species and more than 1% of the global populations of Pied and Sooty Oystercatchers and the near threatened Hooded Plover.

Site description The IBA encompasses the entire known breeding range of the critically endangered Orange-bellied Parrot as mapped in the Orange-bellied Parrot Recovery Plan. The IBA comprises a mosaic of eucalypt forest, rainforest, and moorland and sedgeland plains, extending throughout coastal and near-coastal areas from Birchs Inlet to Louisa Bay in south-west Tasmania. Most of the IBA has a rugged topography with extensive coastal lowland plains rising to rocky mountains. The IBA overlaps with Franklin-Gordon Wild Rivers National Park, Southwest Conservation Area and Southwest National Park. The islands of the Muttonbird, Swainson and Trumpeter groups, which lie offshore from the Melaleuca to Birchs Inlet IBA, and support globally significant numbers of one congregatory waterbird and three congregatory seabird species, comprise the separate Port Davey Islands IBA.

Key Biodiversity The buttongrass plains within the IBA support significant numbers of Ground Parrots. The restricted-range Tasmanian Native-hen and Yellow Wattlebird may occur in the IBA but no confirmed records are cited in Thomas (1979) or were submitted to the Atlas of Australian Birds for the period 1998 to 2008 (Atlas of Australian Birds database).
