Regional biodiversity networking mapping

Regional biodiversity network maps show areas of ecological value to be maintained and where incremental habitat loss, fragmentation and degradation should be avoided.

These maps are a resource that have been incorporated in some regional plans. They are intended to be used by local governments when they undertake town planning scheme reviews and mapping of matters of local environmental significance (MLES). The regional biodiversity network mapping can also assist with developing appropriate management and investment in environmental rehabilitation and restoration activities.

Map layers

Regional biodiversity network maps are comprised of several mapping layers which represent select environmental values across the landscape.

A key feature of these maps is the inclusion of biodiversity values which are identified through the state’s Biodiversity Planning Assessments (BPAs) and Aquatic Conservation Assessments (ACAs).

The regional biodiversity values mapping layer is based on the assessment of:

  • large tracts of vegetation
  • intact terrestrial and aquatic connectivity
  • areas of high species richness and diversity
  • unique ecosystems and representativeness
  • climate adaptation zones and refugia.

Regional biodiversity corridors, which are also identified through BPAs, are displayed on the regional biodiversity network map. These aim to:

  • identify and protect terrestrial and aquatic ecological and evolutionary processes at a landscape scale
  • maximize connectivity between large tracts of remnant vegetation
  • identify key areas for rehabilitation and offsets.

Regional biodiversity corridors can be made up of areas with environmental values but can also include cleared areas where rehabilitation efforts should be focused to restore habitats and connections between remnant areas of vegetation.

Regional biodiversity network maps may also display Matters of state environmental significance (MSES), which are defined in the State Planning Policy (PDF). These are included in the mapping to provide a more complete picture of the extent and hierarchy of areas with important environmental values or areas identified as having potential environmental value or requiring protection or remediation.

The regional biodiversity network map does not include mapping for the following areas:

  • Matters of national environmental significance (MNES) under the Federal Environmental Protection and Biodiversity Conservation Act—this includes areas such as World Heritage Areas or areas protected by international agreements such as the Ramsar Convention on Wetlands
  • state forests and timber reserves
  • regional biodiversity values or corridors within urban areas.
