Australia has many forests of importance due to significant features, despite being one of the driest continents. Australia has approximately 123 million hectares of native forest, which represents about 16% of Australia's land area.〔(Australian Forest Profiles ) – Australian Government Department of Agriculture and Water Resources〕 The majority of Australia's trees are hardwoods, typically eucalypts, rather than softwoods like pine. While softwoods dominate some native forests, their total area is judged insufficient to constitute a major forest type in (Australia's National Forest Inventory ). The (Forests Australia ) website provides up-to-date information on Australia's forests. Detailed information on Australia's forests is available from (Australia's State of the Forests Reports ) that are published every five years. == Forest types == There are 457 forest communities distributed across Australia. These have been grouped into the following seven native forest types, which are characterised by dominant species and the structure of the forest: * Rainforests * Melaleuca forests * Eucalypt forests * Casuarina forests * Callitris forests * Acacia forests * Mangrove forests ''Plantation forests'' (softwood and some hardwood) have been defined as an eighth group that covers trees planted for commercial use. 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「Forests of Australia」の詳細全文を読む スポンサード リンク
