Potential Groundwater Dependent Ecosystem Map for East Gippsland, Victoria

East Gippsland Catchment Management Authority area is covered by a map identifying potential terrestrial and wetland ecosystems likely dependent on groundwater. The dataset was produced by the Department of Energy, Environment and Climate Action using a GIS overlay model with satellite, geological, and groundwater data from circa 1995 to 2005. It represents a statewide screening analysis to locate ecosystems potentially threatened by drainage or groundwater pumping.

Use Cases

• Identify regions for conservation prioritization based on potential groundwater dependence.
• Screen for ecosystems at risk from groundwater extraction or drainage activities.
• Inform land-use planning by overlaying potential GDE locations with development maps.
• Guide field validation studies by highlighting areas flagged by the remote sensing model.

Strengths

• Model integrates multiple data sources: satellite remote sensing, geological data, and groundwater monitoring.
• Covers the entire East Gippsland CMA area as part of a state-wide application.
• Explicitly documents the four-characteristic methodology used for identification.

Limitations

• Validation through field assessment has not been performed.
• The methodology is expected to overestimate the extent of terrestrial GDEs.
• Core data used is largely from 1995-2005, which may not reflect current conditions.
