Serpentine Leafminer Climate Suitability Maps for Australia

Climate suitability maps for the serpentine leafminer pest are provided in GeoTIFF format, derived from eight global climate models and historical observations. The dataset includes monthly suitability, phenophase-specific maps, and ensemble medians, produced by the Department of Primary Industries and Regional Development (DPIRD) as part of a biosecurity risk assessment. Results were generated using a multicriteria analysis framework to assess vulnerability to future climate change.

Use Cases

• Compare climate suitability maps for each month across eight global climate models to analyze seasonal pest risk.
• Model pest phenophase-specific climate suitability using the provided GeoTIFF layers for targeted biosecurity planning.
• Generate ensemble median maps from the eight GCM outputs to produce a consensus view of future pest habitat suitability.
• Assess biosecurity risk by overlaying historical observation-derived suitability maps with future climate projections.

Strengths

• Includes outputs from eight distinct global climate models, allowing for uncertainty analysis.
• Provides data in GeoTIFF format, a standard for geospatial analysis and mapping.
• Contains specific maps for each phenophase and climate variable combination used in the underlying model.
• Derived from a formal multicriteria analysis framework developed for consistent climate vulnerability assessment.

Limitations

• The dataset is focused solely on the serpentine leafminer, limiting broader pest or commodity analysis.
• Spatial coverage is specific to the region of assessment (implied to be Australia), not global.
• Relies on model outputs and assumptions detailed in a separate methodology report, requiring external review for full context.
