Description: Interim Biogeographic Regionalisation for Australia (IBRA) version 7.1 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 7.1 data consists of two datasets. IBRA regions, which is a larger scale regional classification of homogeneous ecosystems, and sub regions, which are more localised. IBRA Version 7.1 is a minor update to IBRA Version 7.0 to coincide with the release of the CAPAD 2024 dataset to more closely conform to the Geoscience Australia (GA) Australia’s Land Borders (see https://pid.geoscience.gov.au/dataset/ga/140044). IBRA Version 7.0 regions and sub regions are realigned to the updated GA jurisdiction borders in some locations. For example, the Victorian Riverina sub region runs along the NSW-Vic border, the border in this area is updated to better align with the river. IBRA Version 7.1 restores the South Bruny land mass portion of Bruny Island (Tas) back to the Southern Ranges region Southern Ranges sub region to which it was assigned in IBRA Version 6.1. The whole of Bruny Island was incorrectly assigned to the South East region and Tasmanian South East sub region in IBRA Version 7. IBRA Version 7.1, aligns Ball’s Pyramid (south of Lord Howe Island) to other coastal data sources.
