Swan Coastal Plain Remnant Vegetation 2005: Pre-1750 Vegetation Extent

Swan Coastal Plain remnant vegetation as of 2005, part of a polygon dataset series representing original pre-1750 vegetation. The dataset was created by the Department of Primary Industries and Regional Development using interpreted aerial photography from 1953 onward and is scheduled for retirement on October 2, 2025. It covers the Swan Coastal Plain bioregion, Metropolitan, and Peel Region Schemes.

Use Cases

• Analyze changes in native vegetation extent over time based on the 2005 snapshot within a multi-year series.
• Model land cover and habitat connectivity based on polygon representations of remnant vegetation.
• Assess vegetation condition trends based on the simplified condition attributes mentioned in the description.
• Validate or compare newer vegetation datasets based on the historical aerial photography interpretation methodology.

Strengths

• Provides a specific snapshot for the year 2005 within a consistent time series (2000, 2005, 2010, 2015, 2020).
• Based on interpreted current and historical digital aerial photography sourced from multiple providers (Landgate, Digital Globe, Google).
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• Dataset is pending retirement and will be replaced by updated DWER services on October 2, 2025.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
