Modelled Old-Growth Forest Boundaries in Victoria Post-2003 Fires

A geospatial layer identifies modelled old-growth forest areas in Victoria, Australia, using disturbance data post-dating the original analyses. The dataset was created by the Department of Energy, Environment and Climate Action and was last updated on 2026-04-09. It incorporates Alpine Fire Severity Mapping from 2003 and logging history records to reclassify conflicting areas.

Use Cases

• Mapping forest disturbance and recovery based on post-2003 fire and logging data.
• Analyzing the spatial distribution of old-growth forests based on Victorian definition criteria.
• Modeling ecological impacts of historical wildfires based on the 2003 Alpine Fire Severity layer.

Strengths

• Data is derived from multiple input datasets including fire severity mapping and logging records.
• Polygons are defined to meet the official Victorian definition of old-growth forest.
• Available in multiple common geospatial file formats including SHP, GDB, and DWG.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• The data is not reliable at scales less than 1:100,000, and not all polygons have been field-checked.
• Column-level documentation is absent; field semantics must be inferred after download.
