VIC DELWP - Victorian Bioregions 1:100,000 (Polygons)

This dataset presents the footprint of Victorian biogeographic regions (bioregions) that capture the patterns of ecological characteristics in the landscape. Victorian bioregions form part of the national framework for the terrestrial environment, the Interim Biogeographic Regionalisation for Australia (IBRA).

Bioregions provide a natural framework for recognising and responding to biodiversity values. As bioregions reflect underlying environmental features, they can also be related to the patterns of use of land and sea, and thus can be used to identify the relationship between many natural resource-based activities and biodiversity assets. Of the eighty IBRA regions delineated across Australia, eleven regions occur in Victoria with eight of these shared with adjacent States. The broad scale that is appropriate for national purposes does not adequately discriminate between areas that are meaningful at the Statewide scale and further refinement has delineated 28 Victorian bioregions. Victorian bioregions are equivalent to the Victorian part of IBRA subregions. The layer will primarily support flora and fauna biodiversity evaluations and management. The layer has been used to subdivide extant ecological vegetation classes (EVCs) for the purposes of determining a bioregional conservation status rating for EVCs. The dataset incorporates 6 new Victorian Bioregions to those identified in the VBIOREGION250 dataset.

Please note:

  • The boundaries are aligned with pre-1750 ecological vegetation class boundaries mapped at 1:100,000.
  • Positional accuracy is a function of pen thickness, base accuracy and nature of boundaries mapped. Map errors of 0.5 mm to 3 mm, or 50 m to 300 m are possible.
