ACT Hydrogeological Wetland Vulnerability for Land Management

ACT Hydrogeological Wetland Vulnerability contains digital spatial data developed by the ACT Government to assist in land management decision making. The dataset provides hazard ratings for land salinity, stream salt load, and stream EC, along with overall salinity hazard for each Hydrogeological Landscape (HGL) unit. It incorporates information sources such as soil landscape maps, site characterisation, and hydrogeological data, captured at a 1:25,000 scale.

Use Cases

• Assessing land salinity hazard for paddock-scale management based on HGL unit ratings.
• Evaluating stream salt load and EC (electrical conductivity) for water quality monitoring.
• Identifying appropriate salinity management strategies based on listed landscape functions.
• Mapping hydrogeological landscapes to understand salt stores and mobilization pathways.
• Integrating causative factors like geology, soils, and slope for regional salinity modeling.

Strengths

• Data is captured at a 1:25,000 scale, suitable for paddock-scale assessment.
• Includes hyperlinks to full management descriptions for each HGL unit.
• Integrates multiple information sources such as soil maps, salinity occurrence maps, and hydrogeological data.

Limitations

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