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).<\/div>
<\/div>
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\u2019s Land Borders (see https://pid.geoscience.gov.au/dataset/ga/140044).<\/div>",
