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. People external to DBCA can download the external version from DataWA at this link https://catalogue.data.wa.gov.au/dataset/dbca Note: to access the data, select the data source link located on the right-hand side.

This dataset categorises the 2020 native vegetation extent mapping by vegetation complexes for the Swan Coastal Plain and the South West Forest Region of Western Australia.

Department of Parks and Wildlife (DPaW) - Vegetation Complexes - SCP250k The dataset shows pre-1750 distribution of vegetation complexes characteristic of various combinations of landforms, soils and rainfall along the Swan Coastal Plain south of Lancelin. For the majority of this area, the vegetation complexes are those defined by Heddle et al. (1980) at the scale of 1:250,000 and include some minor attribution corrections undertaken in 2015. The Heddle mapping was restricted to the System 6 area and thus the vegetation complex mapping did not extend to the far southern section of Swan Coastal Plain. This southern section was subsequently captured by Webb et al. (2016) at a scale of 1:250,000. The 2016 mapping also consolidated the vegetation complex boundaries along the Whicher and Darling scarp interface using complexes defined by Mattiske & Havel (1990), soil landscape phases (DAFWA 2007) and information in Hagan et al. (2011). See additional metadata for information on the location of summary descriptions of each complex and references.

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)

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 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 pre-European state-wide vegetation mapping of Western Australia.

Natural areas were identified by combining the National Vegetation Information System Version 4.1 data, and the National Carbon Accounting Forest Cover Version 8 data (after removing areas of plantation forestry).Plantation forestry areas were removed using three ABARES datasets 'Australia's plantations 2011', the 'Forests of Australia 2008' and the November 2012 version of the 'Catchment Scale Land Use Mapping For Australia'.Without information on the relative condition of Australia's natural areas, it has only been possible to identify areas into either one of two classes, those that are presumed to be relatively natural, and those that have been highly modified.Natural Areas were developed from a combination of: National Vegetation Information System (NVIS v4.1); Department of Climate Change, Energy, the Environment and Water 2012.

This data package is a derivative product consisting of a summary of the published data package Woodland Restoration Plot Network: Vegetation Structure and Composition Data, Western Sydney Parklands (Western Sydney Regional Park), NSW, Australia, collected in 2001. (http://www.ltern.org.au/knb/metacat/ltern.120/html). These data are used to produce the graph and conclusions found in figure 8.30 on page 314 of Lindenmayer et. al 2014, Biodiversity and Environmental Change: Monitoring Challenges and Directions. These data show trends in compositional similarity of revegetated sites to remnant native vegetation in the first decade since planting (1992-2001) in a woodland restoration project. The lack of convergence between revegetated areas and native woodlands in species composition suggests that there has been little colonisation of native species in the revegetated sites. These data were collected from twenty-five 0.1 hectare sites which were established in a 10-year chronosequence of plantings that was sampled in 2001. The sites were located on retired farmland that includes a mosaic of restored vegetation (native plantings) of varying ages juxtaposed with patches of remnant vegetation and untreated, abandoned pasture. All sites were originally woodland prior to agricultural development about 200 years ago. The plantings monitored by the Woodland Restoration Plot Network research plots commenced in 1992 and have been revisited every 3-4 years since 2001. A synopsis of related data packages which have been collected as part of the Woodland Restoration Plot Network’s full program is provided at http://www.ltern.org.au/index.php/ltern-plot-networks/woodland-restoration
