ASDST Scarred Trees Pre1750 Model: Predictive Likelihood for NSW

New South Wales is covered by a raster GIS model predicting the likelihood of scarred trees prior to European colonization. The model is part of the Aboriginal Sites Decision Support Tool suite, produced by the NSW Department of Planning, Industry and Environment in 2020 at 50-meter resolution. Cell values range from 0 to 1000, indicating relative likelihood rather than probability.

Use Cases

• Assess landscape planning risks based on predicted likelihood of scarred trees.
• Compare pre-colonial and current landscape feature likelihoods for impact analysis.
• Prioritize field survey areas based on model reliability and data gaps.
• Support Aboriginal heritage information management by extending site distribution maps.

Strengths

• Model covers the entire state of New South Wales.
• Provides a specific pre-1750 predictive layer for scarred trees (TRE).
• Uses a standardized likelihood scale from 0 to 1000.

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 bias inherent to data_gov_au.
