2016 SoE Heritage Interim Biogeographic Regionalisation for Australia

Interim Biogeographic Regionalisation for Australia (IBRA), Version 7 (Regions)\r\n\r\nInterim Biogeographic Regionalisation for Australia (IBRA) version 7.0 represents a landscape based approach to classifying the land surface of Australia. 89 biogeographic regions and 419 sub regions have been delineated, each reflecting a unifying set of major environmental influences which shape the occurrence of flora and fauna and their interaction with the physical environment across Australia and its external territories (excluding Antarctica). IBRA Version 7.0 data consists of two datasets. IBRA bioregions, which is a larger scale regional classification of homogenous ecosystems, and sub regions, which are more localised. IBRA Version 7.0 is the result of both significant changes to certain IBRA 6.1 boundaries, plus refinement of other boundaries due to better data availability amongst some states and territories, and alterations by the states/territories along state borders. The updated boundaries were jointly defined by the Commonwealth, State and Territory nature and conservation agencies. In this respect refinements were carried out to all mainland jurisdictions with significant changes in Queensland and South Australia. In addition the dataset was also updated to more closely conform to the Geoscience Australia 1:100K State borders, and a standard coding/naming convention introduced (for both regions and sub-regions) resulting in differences to both names and codes used in earlier IBRA Versions. Various sources were used to delineate islands - these included the GA100K Admin layer plus the Australian Maritime Boundaries dataset, a Coral Sea dataset (held in ERIN) and the GA Commonwealth Fisheries 2006 dataset.\r\n\r\nCredit:\r\nSA: Department of Environment and Natural Resources (DENR); WA: Department of Environment and Conservation (DEC); NT: Department of Natural Resources, Environment, The Arts and Sport (NRETAS); NSW: Office of Environment and Heritage (OEH); Vic: Department of Sustainability and Environment (DSE); Tas: Department of Primary Industries, Parks, Water and Environment (DPIPWE); QLD: On 30 March 2012 the Queensland Government announced machinery-of-government changes for departments.

澳大利亚临时生物地理区域划分（Interim Biogeographic Regionalisation for Australia，IBRA）第7版（区域数据集）

澳大利亚临时生物地理区域划分（IBRA）7.0版采用基于景观的方法对澳大利亚陆地表面进行分类。该体系共划定89个生物地理区域及419个子区域，每个区域均体现了一组统一的核心环境影响因素，这些因素塑造了澳大利亚及其海外领地（南极洲除外）范围内动植物的分布格局，以及它们与自然物理环境的相互作用。

IBRA 7.0版数据集包含两类数据：一类是IBRA生物地理区域，即针对同质生态系统的大尺度区域分类单元；另一类是子区域，即尺度更为精细的局部分类单元。IBRA 7.0版的编制，既包含对部分IBRA 6.1版边界的重大调整，也涵盖了因部分州和领地获取了更优质的基础数据而对其他边界进行的优化，同时纳入了各州/领地沿州界提出的边界调整方案。更新后的边界由澳大利亚联邦、各州及领地的自然保护与管理机构共同划定。就此而言，所有大陆辖区均完成了边界优化工作，其中昆士兰州与南澳大利亚州的调整幅度最为显著。此外，本数据集还进行了适配性更新，以更贴合澳大利亚地球科学局（Geoscience Australia）发布的1:10万比例尺州界数据，并引入了适用于区域及子区域的标准化编码与命名规范，因此与此前IBRA各版本的名称及编码均存在差异。岛屿边界的划定参考了多类数据源，其中包括GA100K行政图层、澳大利亚海洋边界数据集、珊瑚海数据集（存储于ERIN）以及GA 2006年英联邦渔业数据集。
