Summary The island supports the world's largest population of the endangered Forty-spotted Pardalote, up to one third of the world population of the endangered Swift Parrot, and 13 of Tasmania's 14 endemic bird species.

Site description The IBA includes the whole of Bruny Island, a large island off the south-east of Tasmania and some close inshore islets. The whole island is taken as an IBA because it supports 76 widely-distributed colonies of Forty-spotted Pardalotes scattered across the whole island, often in farmland, and Swift Parrots are scattered across much of the forest. Bruny is geographically two islands joined by a narrow sandy isthmus. Most of the island is eucalypt forest and cattle-grazed fields, but there are also several small towns, notably Alonnah, Adventure Bay and Lunawanna. Some forests are logged, but there are seven protected areas, notably the South Bruny National Park, and two Forest Reserves. The seaward coast is mostly extremely rugged, with cliffs of dolerite that tower over 200 metres above sea level, but with the long sandy beaches of Adventure Bay and Cloudy Bay. The island has a temperate maritime climate with mean annual rainfall of about 890 mm.
