Swan Coastal Plain Remnant Vegetation Extent Mapping 2020

Polygon data maps remnant native vegetation for the Swan Coastal Plain bioregion and Perth-Peel region in 2020. The dataset is part of a temporal series representing vegetation extent at five-year intervals from 2000 to 2020 and the year 2024. Mapping was performed by the Department of Water and Environmental Regulation using historical and current aerial photography.

Use Cases

• Analyze changes in vegetation extent over time by comparing the 2020 polygons with other years in the series (2000, 2005, 2010, 2015, 2024).
• Assess vegetation condition by examining the simplified condition attribute attached to some polygons.
• Model habitat connectivity or fragmentation using the polygon geometry and the defined Swan Coastal Plain vegetation complexes.
• Integrate with land-use planning schemes by overlaying polygons with the Metropolitan and Peel Region Scheme boundaries.

Strengths

• Provides a multi-temporal series with snapshots from 2000, 2005, 2010, 2015, 2020, and 2024 for change analysis.
• Based on interpreted aerial photography spanning from 1953 to the present.
• Covers a defined biogeographic region (Swan Coastal Plain) and specific planning scheme areas.

Limitations

• Vegetation condition is only a simplified attribute and is not attributed to all polygons.
• The dataset represents interpreted areas, not ground-truthed surveys, which may introduce classification errors.
• No row or feature count is provided to gauge the dataset's granularity or scale.
