Swan Coastal Plain Remnant Vegetation Extent 2024

Remnant vegetation mapping for the Swan Coastal Plain bioregion and Perth-Peel Region Scheme areas. The dataset represents interpreted areas of original pre-1750 vegetation using aerial photography from 1953 to the present, with simplified condition attributes for some polygons. It is part of a temporal series capturing vegetation extent at 5-year intervals from 2000 to 2020, plus the year 2024.

Use Cases

• Analyze changes in vegetation extent over time using the 2000-2024 temporal series to track habitat loss or recovery.
• Model the relationship between vegetation condition attributes and historical land-use patterns derived from aerial photography.
• Integrate polygon data with the Swan Coastal Plain vegetation complexes (DBCA-046) layer for regional conservation planning.
• Assess remnant vegetation coverage within the Metropolitan and Peel Region Schemes for urban development impact studies.

Strengths

• Provides a multi-decade temporal series with snapshots from 2000, 2005, 2010, 2015, 2020, and 2024.
• Uses interpreted aerial photography sourced from 1953 to the present for historical context.
• Covers the defined Swan Coastal Plain bioregion and the Metropolitan and Peel Region Scheme areas.
• Includes simplified condition attributes for some vegetation polygons.

Limitations

• Vegetation condition data is simplified and not attributed to all polygons, limiting detailed ecological analysis.
• The dataset's accuracy depends on the interpretation of aerial imagery, which may introduce classification errors.
