Swan Coastal Plain Remnant Vegetation 2020: Pre-1750 Vegetation Extent

2020 data on remnants of original pre-1750 vegetation on the Swan Coastal Plain in Western Australia. The dataset consists of polygon features created by the Department of Primary Industries and Regional Development (DPIRD) using interpreted current and historical digital aerial photography from 1953 onward. It is part of a time series for the years 2000, 2005, 2010, 2015, and 2020, but is scheduled for retirement and replacement by October 2, 2025.

Use Cases

• Mapping historical vegetation loss based on interpreted aerial photography from 1953 to the present.
• Assessing conservation priorities based on the extent of pre-1750 remnant vegetation.
• Monitoring land cover change over time by comparing this 2020 dataset with other years in the series.
• Analyzing vegetation condition patterns using the simplified condition attributes mentioned in the description.

Strengths

• Provides a temporal snapshot for 2020 as part of a multi-year series covering 2000, 2005, 2010, 2015, and 2020.
• Based on interpreted aerial photography sourced from Landgate, Digital Globe, and Google spanning from 1953 to the present.
• Covers a defined geographic area including the Metropolitan and Peel Region Schemes and the Swan Coastal Plain bioregion.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is explicitly marked as pending retirement and will be replaced by October 2, 2025.
