Victorian Flora Biodiversity Records with High Spatial Accuracy

Flora taxa records from the Victorian Biodiversity Atlas, including most threatened taxa, with unrestricted public access. The dataset includes attributes such as survey location, date, taxa recorded, counts, and locational accuracy. It is maintained by the Department of Energy, Environment and Climate Action and was updated in April 2026.

Use Cases

• Model species presence using the 'taxa recorded' and 'counts' fields against environmental covariates.
• Assess temporal trends in flora observations by analyzing the 'date' and 'time' columns across survey years.
• Filter for high-precision ecological studies using the 'locational accuracy' field to select records with +/- 1m to 500m precision.
• Evaluate survey methodology impact by comparing 'observation type' and 'survey type' across different collector records.
• Verify record quality for research by checking the 'reliability of the record' and 'survey id' attributes.

Strengths

• Includes records for most threatened flora taxa, supporting conservation research.
• Spatial accuracy is documented per record, ranging from +/- 1m to +/- 500m.
• Taxonomic status reflects current legislation, with the FFG field updated for the 2021 FFG Act amendments.

Limitations

• Excludes all restricted taxa records, which are held in a separate, access-controlled dataset.
• Sample size and total row count are unknown, limiting statistical power assessment.
• The actual point accuracy varies widely, which may affect fine-scale spatial analysis.
