Salinity Potential Map of Western Sydney with Four Severity Classes

Four classifications of salinity potential for the Cumberland Plain, covering Western Sydney from Windsor to Campbelltown. The map depicts the distribution and potential severity of dryland salinity based on known biophysical factors. It was published by the NSW Department of Climate Change, Energy, the Environment and Water and last updated on 2026-05-12.

Use Cases

• Assess land development suitability based on salinity potential classifications.
• Model environmental risk for agricultural or conservation planning based on biophysical factors.
• Validate and extend previous salinity hazard mapping work for the Wianamatta Shales geological group.
• Inform policy and guidelines for dryland salinity management in urban fringe areas.

Strengths

• Provides four distinct classifications of salinity potential, from 'Known Salinity' to 'Very Low Salinity Potential'.
• Covers a defined geographic area: the Wianamatta Shales geological group on the Cumberland Plain, north to Windsor and south to Campbelltown.
• Extends and incorporates previous work, specifically the Draft Salinity Hazard Map for Western Sydney.
• Available in multiple formats suitable for GIS analysis: PDF, KML, ZIP, and an ArcGIS REST Service.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale ML projects.
