Internal records
Third-party data sources
Maps showing the locations of Australian forests, by type, are available at Forests Australia – Forest maps (select Interactive maps of Australia’s forests – Forests of Australia).
Site-specific measurements or model outputs
Data on area of Australian cultivated timber resources are available in the latest version of Australian plantation statistics.
