Prescribed Burn Land Management Zones for Southwestern Australia

Three Land Management Zones (LMZs) define fire management areas on Parks and Wildlife land in relation to populated areas. The dataset supports a 200,000 hectare prescribed burning target allocated proportionally across zones. It is produced by the Department of Biodiversity, Conservation and Attractions and was last updated in March 2026.

Use Cases

• Analyze the spatial distribution of the three Land Management Zones (LMZ-A, LMZ-B, LMZ-C) relative to populated areas for fire management planning.
• Calculate the proportional allocation of the 200,000 hectare prescribed burning target across each Land Management Zone based on managed land area.
• Model fire behavior and spotting distances using zone-specific depth definitions, such as LMZ-A depth based on fuels in LMZ-B.
• Assess land management objectives, like reducing ember attack likelihood in LMZ-A or arresting high-intensity fires in LMZ-B, against spatial zone boundaries.

Strengths

• Defines a structured three-zone (LMZ-A, LMZ-B, LMZ-C) land management framework for prescribed burning.
• Supports a specific, quantified fire management target of 200,000 hectares for prescribed burning.
• Published by the authoritative Department of Biodiversity, Conservation and Attractions.
• Available in multiple geospatial formats including GeoJSON, SHP, and Geopackage for interoperability.

Limitations

• Spatial coverage is limited to Parks and Wildlife managed land within the Southwestern Bushfire Risk Zone (SWBRZ), not statewide.
• Dataset is conceptual and policy-based; actual fuel conditions or burn history within zones may require integration with other data.
