ACT Hydrogeological Wetland Classification for Land Management

ACT Government spatial data provides hazard ratings for land salinity, stream salt load, and stream EC across Hydrogeological Landscape units. The dataset integrates geology, soils, slope, regolith thickness, and climate to map salinity pathways at a 1:25,000 scale. Rob Muller, Wayne Cook, Allan Nicholson, and Alie Cowood contributed to this tool for paddock-scale assessment in the Australian Capital Territory.

Use Cases

• Assess land salinity hazard ratings for specific Hydrogeological Landscape units.
• Evaluate stream salt load and electrical conductivity (EC) hazards for water quality management.
• Identify appropriate salinity management strategies based on landscape function descriptions.
• Map spatial patterns of salt stores and mobilization pathways using integrated causative factors.
• Support paddock-scale land management decision-making with 1:25,000 scale spatial data.

Strengths

• Captured at a 1:25,000 scale, suitable for paddock-scale assessment.
• Integrates multiple causative factors: geology, soils, slope, regolith thickness, and climate.
• Includes hyperlinks to full management descriptions for each Hydrogeological Landscape unit.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The ACT Government disclaimer states the map may not be free from error.
• Row count is unknown, which may limit suitability assessment.
