IBRA regions represent a landscape based approach to classifying the land surface of Australia from a range of continental data on environmental attributes. 85 biogeographic 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. IBRA Version 5.1 is the result of refinement of the IBRA Version 4 boundaries. These refined boundaries were jointly defined by the Commonwealth, State and Territory nature and conservation agencies. Following a Departmentally facilitated workshop on the revision of boundaries on 24 July 2000, spatial data refinements were undertaken by DEWHA in conjunction with relevant State / Territory agencies. Agreement from all contributing parties, to make the final IBRA5_1 dataset publicly available, was gained in November 2000. Nominal attributes for the IBRA are; climate, lithology/geology, landform, vegetation, flora and fauna, and landuse. The use of these attributes varies across the States and details can be found in "Revision of the Interim Biogeographic Regionalisation of Australia (IBRA) and Development of Version 5.1 - Summary Report", DEH, Sept 2000. This dataset is available in ArcInfo export file format, Projection Geographicals, Datum and Spheroid WGS84.
