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

Victorian Biodiversity Atlas fauna data is aggregated to a 1-minute latitude/longitude grid (GDA94). The layer counts species records per cell, includes the 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 April 9, 2026.

Use Cases

• Mapping species richness and distribution based on aggregated record counts per grid cell.
• Analyzing temporal trends in species presence using the first and last recorded dates per cell.
• Identifying areas of high biodiversity value for conservation planning based on the summarized grid data.
• Comparing fauna data across different spatial scales using related 5-minute and 10-minute grid summaries.

Strengths

• Data is spatially standardized on a consistent 1-minute grid (GDA94).
• Filters for spatial accuracy by excluding records with precision worse than +/- 1 km.
• Summarizes temporal range with first and last recorded dates per taxon per cell.

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.
