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 subregions 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 subregions, 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 subregions are realigned to the updated GA jurisdiction borders in some locations. For example, the Victorian Riverina subregion 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 subregion 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 subregion in IBRA Version 7. IBRA Version 7.1, aligns Ball’s Pyramid (south of Lord Howe Island) to other coastal data sources.

This dataset is managed by Environment Information Australia and is updated when new listings take effect, or a significant number of distributions have been added or updated.The data contains generalised versions of species distributions that have been modelledfor department use. This data should not be used for quantitative analysisdue to the level of generalisationapplied.This vector product contains distribution models for Species of National Environmental Significance (those listed as threatened or migratory)and some EPBC Act listed marineand cetacean species. The distributions are at a national scale and are indicative only. They are not intended for use at a local or regional scale and should not be used for absolute area calculations. The primary purpose of the data is to narrow the list of species or species habitat that might reasonably occur in an area of interest when undertaking a spatial search for protected matters under the EPBC Act. Data is stored by map_id(SpeciesProfiles and Threats database (SPRAT) taxon_id)for the current scientific name at the time of mapping) and includes non-overlapping presence rank categories which can beone of:1 - Species or species habitat may occur within area2 - Species or species habitat is likelyto occur within area Region Codes:ACT Australian Capital TerritoryNSW New South WalesNT Northern TerritoryQLD QueenslandSA South AustraliaTAS TasmaniaVIC VictoriaWA Western AustraliaACI Ashmore and Cartier IslandsCKI Cocos (Keeling) IslandsCI Christmas IslandCSI Coral Sea IslandsJBT Jervis Bay TerritoryNFI Norfolk IslandHMI Heard and McDonald IslandsAAT Australian Antarctic TerritoryCMA Commonwealth Marine AreaField descriptions:LISTED_TAXON_ID Taxonomic identification number in Species Profile and Threats Database (SPRAT)MAP_TAXON_ID Taxonomic identification number of associated GIS data within the departmentSCIENTIFIC_NAME Scientific name at the time of listing under the EPBC Act.
