Victorian Biodiversity Atlas Flora Records Summarized on a 1-Minute Grid

Victorian Biodiversity Atlas flora records are aggregated against a standard 1-degree longitude/latitude grid (GDA94). The dataset counts records per taxon per grid cell, includes first and last observation dates, and excludes records with spatial accuracy worse than +/- 1 km. It is published by the Department of Energy, Environment and Climate Action and was last updated on 2026-04-09.

Use Cases

• Mapping plant species distribution across Victoria based on aggregated grid cell counts.
• Analyzing temporal trends in species observations based on the first and last recorded dates per cell.
• Identifying areas of high botanical diversity or recording effort based on the collated RECORDS column.
• Comparing flora data with other environmental layers using the standardized 1-minute grid geometry.

Strengths

• Excludes records with spatial accuracy worse than +/- 1 km, improving locational reliability.
• Summarizes first and last observation dates per taxon per cell, enabling temporal analysis.
• Related datasets provide the same data summarized against 10 and 5 minute grids for multi-scale analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
