A small area of the great Malesian tropical rain forests extends into Australia. The flora and fauna have some Malesian affinities, but include many unique species. The forests occur as small patches mainly close to the coast of Queensland. Despite their limited extent much of the original area has survived. Disturbance of the forest, including selective felling for high-quality timber, has been stopped by federal government decree and the forests have been listed as a World Heritage area. Introduction The huge continent of Australia extends between approximately 10°- SO^S latitude and 110°-l55°E longitude. The climate, soils, topogra- phy and vegetation are, necessarily, very varied over this large land mass. The tropical rain forests occur in Queensland, in the north-east of the continent, where they take up only a little over 0.1 per cent of the country. They are found along the coastal plains at sea level, over the undulating tablelands and reach to almost the top of the highest mountain in the area (Mount Bartle Frere, 1612 m). Much of the topography in the region is rugged, with numerous fast-flowing rivers, gorges and waterfalls. The rain forests are fringed and dis- sected by other vegetation types including sclerophyll forest and woodland, mangroves and swamps. This varied array of habitats supports a rich and diverse flora and fauna. Rainfall is higher in the region of tropical rain forest than an
