Terrestrial Groundwater Dependent Ecosystem Density and Biodiversity Value for Victoria

A geospatial dataset ranking terrestrial biodiversity value and groundwater dependent ecosystem density across Victoria. It combines Potential Terrestrial GDE mapping from Dresel et al. (2010) with Natureprint V2.0 biodiversity rankings from DSE (2011). The dataset is provided by the Department of Energy, Environment and Climate Action and was last updated on 2026-04-27.

Use Cases

• Prioritizing conservation areas based on combined groundwater dependency and biodiversity value scores.
• Analyzing spatial overlap between high biodiversity value regions and groundwater dependent ecosystems.
• Informing land-use planning decisions to protect ecosystems reliant on groundwater.
• Modeling ecosystem integrity and complementarity for reserve design using the Zonation software framework.

Strengths

• Integrates two established, peer-reviewed inputs: Dresel et al. (2010) GDE mapping and DSE (2011) Natureprint V2.0.
• Biodiversity values are ranked on a defined 0-7 scale, providing a consistent metric for comparison.
• Available under a permissive CC-BY-4.0 license for reuse and adaptation.
• Offered in multiple standard geospatial raster formats including TIFF, GEOTIFF, and JPEG 2000.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale statistical modeling.
• The temporal coverage of the source inputs (2010-2011) may not reflect current conditions.
