Victorian Bioregions Mapped at 1:100,000 Scale

Victorian biogeographic regions delineate patterns of ecological characteristics in the landscape. The dataset provides a natural framework for biodiversity assessment and forms part of the national Interim Biogeographic Regionalisation for Australia (IBRA). It is published by the Department of Energy, Environment and Climate Action and was last updated in April 2026.

Use Cases

• Conservation planning based on pre-1750 ecological vegetation class boundaries.
• Biodiversity value assessment based on the framework of Victorian bioregions.
• Regional environmental reporting based on alignment with the national IBRA framework.
• Landscape ecological analysis based on patterns of ecological characteristics.

Strengths

• Boundaries are aligned with pre-1750 ecological vegetation class boundaries.
• Dataset is part of the national Interim Biogeographic Regionalisation for Australia (IBRA) framework.
• Upgrades a previous dataset (VBIOREGION250) based on higher-resolution 1:100,000 mapping.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
