Spatial layers describe forest canopy loss and recovery across New South Wales from 1998 to 2020. The dataset was generated by the NSW Forest Monitoring and Improvement Program using a Multiple Lines of Evidence approach and base grids from the NSW State-wide Historic Forest Cover Extent product. It supersedes a previous version covering 1998 to 2019.
Use Cases
- Map forest disturbance events based on the described canopy loss and recovery layers.
- Analyze recovery time trends based on the time taken for forest patches to return to a 20% canopy cover threshold.
- Investigate landscape-scale forest loss drivers based on the attributed disturbance context layer.
- Assess forest health indicators based on the described measures of canopy loss and recovery.
Strengths
- Covers a 22-year time series from 1998 to 2020.
- Applies a Multiple Lines of Evidence approach to attribute disturbances.
- Derived from a state-wide historic forest cover extent product.
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.
