Victorian Fauna Biodiversity Records Summarized on a 5-Minute Grid

Victorian Biodiversity Atlas fauna records aggregated to a standard 5-minute longitude/latitude grid (GDA94). The dataset includes counts of taxon records per cell, along with the first and last recorded dates for each taxon within a cell. It is published by the Department of Energy, Environment and Climate Action and was last updated on 2026-04-09.

Use Cases

• Modeling species distribution and richness based on aggregated record counts per grid cell.
• Analyzing temporal trends in species observations based on the first and last recorded dates per cell.
• Creating regional biodiversity maps and conservation priority assessments based on the geospatial grid summary.
• Comparing fauna data across different spatial scales using the related 10-minute and 1-minute grid datasets.

Strengths

• Data is spatially standardized on a consistent 5-minute grid (GDA94).
• Includes temporal metadata (first and last recorded dates) for each taxon per cell.
• Records with low spatial accuracy (worse than +/- 4.5 km) are excluded to improve reliability.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to citizen science and agency collection methods.
