This dataset categorises the 2020 native vegetation extent mapping by pre-European state-wide vegetation mapping of Western Australia.

This dataset categorises the 2020 native vegetation extent mapping by administrative categories relevant to local biodiversity conservation planning. It identifies ‘Local Natural Areas’, various categories of Parks and Wildlife Service managed lands, Regional Parks and Bush Forever. ‘Local Natural Areas’ are the focus of Local Biodiversity Strategies prepared in accordance of the Local Government Biodiversity Planning Guidelines (del Marco et al 2004).

This dataset categorises the 2020 native vegetation extent mapping by the conservation priority of vegetation complexes in the Perth and Peel Region Schemes areas, considering the potential retention and protection status of vegetation complexes. The potential retention is based on vegetation complex extent by land use categories in the Metropolitan Region Scheme and the Peel Region Scheme as in 2016.

This annual report provides up-to-date statistics on the pre-European and current extent of the vegetation complexes of the south-west of Western Australia. The mapping does not extend to IBRA sub-region boundaries so it does not report by IBRA sub-region rather by the extent of the available mapping of the complex. The report also includes (1) statistics to assess the status of the CAR reserve system for a portion of the South West Region; (2) Region Scheme reports; (3) LGA Reports. This analysis is based on the Vegetation Complex mapping of the Swan Coastal Plain and South West Forests. This annual reporting was initiated in 2016 after the two vegetation complex mapping datasets were updated. The reports contains both external reports and the internal (DBCA and DWER) sub-reports. See the README worksheet in each excel file for more details.

This dataset categorises the 2020 native vegetation extent mapping by the number of agreed ecological criteria. The set of criteria were developed through the Regional Framework for Local Biodiversity Conservation Priorities for Perth and Peel project, delivered via WALGA’s Perth Biodiversity Project in 2012. The prioritisation criteria builds on State Government endorsed local biodiversity conservation planning methodology adopted by Local Governments preparing Local Biodiversity Strategies in Perth and its surrounds.

Department of Parks and Wildlife (DPaW) - Vegetation Complexes - SWF50k The dataset is a comprehensive coverage of pre-1750 distribution of vegetation complexes of the south west forest region of Western Australia. This 1:50,000 mapping was undertaken by Mattiske and Havel (1998) as part of the biodiversity assessment for the comprehensive regional assessment for the south west forest region. The outputs from this project were used as inputs to the assessments of national estate, ecologically sustainable forest management, endangered species and the integration of all these values in the 1999 Regional Forest Agreement (RFA). This dataset covers the full extent mapped by Mattiske and Havel (1998) not just the area within the RFA boundary. In March 2015 the dataset was reviewed to correct known and documented minor attributing errors and additional fields were incorporated including a unique numerical identifier (SWFor_ID). Webb et al. (2016) reviewed the 1:50,000 mapping of the Whicher Scarp and changes were made to ensure the complexes were a continuation of those defined by Mattiske and Havel (1998) and the extent of the landform correlated to that as defined by soil-landscape mapping (DAFWA 2007). In addition the review consolidated the boundaries along the Whicher and Darling Scarp interface with the Swan Coastal Plain. All Swan Coastal Plain complexes were removed and incorporated into the 2016 mapping of the “Swan Coastal Plain Vegetation Complexes” (Webb et al. 2016).

Remnant vegetation mapping for the Swan Coastal Plain bioregion, Metropolitan and Peel Region Scheme areas in 2020. Part of a suite of polygon datasets that best represent remnants of original pre-1750 vegetation across the mapped areas as at 2000, 2005, 2010, 2015, 2020 and 2024. The polygons represent interpreted areas of vegetation using current and historical digital aerial photography (1953-present) sourced from State Government repositories and other commercial products e.g. Digital globe, ESRI wayback imagery and Google. Simplified condition of the vegetation has been attributed to some polygons. The mapped area covers the Metropolitan and Peel Region Schemes, the Swan Coastal Plain bioregion as defined in the Interim Biogeographic Regionalisation of Australia V 7.1 (Commonwealth of Australia, 2025) and the Swan Coastal Plain vegetation complexes (DBCA-046) (Department of Parks and Wildlife, 2016).

Biddiscombe, E.F. (1963) Vegetation Survey in the Macquarie Region, NSW. Division of Plant Industry Technical Paper No. 18. CSIRO, Melbourne. Description of the native vegetation of the Macquarie and Castlereagh river systems where these traverse the lower Western Slopes and adjoining sections of the Plains. The vegetation is classified into 22 floristic associations which are grouped into 11 alliances (4 forest, 5 woodland, 1 mallee and 1 grassland). Mapping is based on ground traverses and aerial photography. (VIS_ID 818)
