The Brigalow Belt is a wide band of acacia wooded grassland that runs between tropical rainforest of the coast and the semi-arid interior of Queensland, Australia. The Northern and Southern Brigalow Belts are two of the 85 bioregions across Australia and the 15 bioregions (see Interim Biogeographic Regionalisation for Australia) in Queensland. Together they form most of the ''Brigalow tropical savanna'' ecoregion. ==Location and description== The Northern Brigalow Belt covers just over 13.5 million hectares and reaches down from just north of Townsville, to Emerald and Rockhampton on the tropic, while the Southern Brigalow Belt runs from there down to the Queensland/New South Wales border and a little beyond until the habitat becomes the eucalyptus dominated Eastern Australian temperate forests. This large, complex strip of countryside covers an area of undulating to rugged slopes, consisting of ranges as well as plains of ancient sand and clay deposits, basalt and alluvium. The Northern Brigalow Belt includes the coal producing Bowen Basin with the nearby Drummond Basin and the fertile Peak Downs areas while the southern belt runs into the huge Great Artesian Basin with the sandstone gorges of the Carnarvon Range of the Great Dividing Range separating the two areas. The south-west side includes the farming area of Darling Downs. A number of important rivers drain the Brigalow Belt mostly running eastwards towards the coast, including the large Fitzroy River system and the Belyando and Burdekin rivers near the tropic. The south-western areas drain westwards into the Murray-Darling basin via the Maranoa, Warrego and Condamine Rivers. The northern belt has tropical summer rains and warm weather all year round, while south of the tropic the winter is slightly cooler and there is more year-round rainfall as well as the summer. All along the belt the interior with less than 500 mm of rainfall per year is drier than the coast which may have 750 mm and more. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Brigalow Belt」の詳細全文を読む スポンサード リンク
