This dataset identifies regional ecological linkage axis lines that aim to link patches of remnant vegetation judged to be of regional significance by retaining the best (condition) and/or most contiguous patches available to act as stepping stones for flora and fauna between regionally significant areas. Read the South West Regional Ecological Linkages (SWREL) report for more information on how to interpret the current dataset and on how to use a proximity analysis tool available to the study area.

This dataset identifies regional and local ecological linkages mapped to broadly represent a link between patches of remnant vegetation judged to be of conservation significance in the Shire of Chittering. These ecological linkage were identified in support of the Shire of Chittering’s biodiversity conservation planning. See full metadata Metadata-Appendix 1 for the description of the methodology and how to use the dataset.

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.

This dataset identifies the location of 51 Reference Sites for which information is available on characteristics of typical plant communities, including 40 sites across the Swan Coastal Plain and 11 sites in the Jarrah Forest of the Perth Metropolitan Region. Information on how to select a relevant Reference Site and detailed information for each reference site are available via separate documents: • Part A: Project overview • Part B: Bush Forever Reference Sites • Part C: Jarrah Forest Reference Sites • Index of Bush Forever Reference Sites (Excel Table)

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).

## **Abstract** This dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied. Resource contains an ArcGIS file geodatabase raster for the National Vegetation Information System (NVIS) Major Vegetation Groups - Australia-wide, present extent (FGDB_NVIS4_1_AUST_MVG_EXT). Related datasets are also included: FGDB_NVIS4_1_KEY_LAYERS_EXT - ArcGIS File Geodatabase Feature Class of the Key Datasets that make up NVIS Version 4.1 - Australia wide; and FGDB_NVIS4_1_LUT_KEY_LAYERS - Lookup table for Dataset Key Layers. This raster dataset provides the latest summary information (November 2012) on Australia's present (extant) native vegetation. It is in Albers Equal Area projection with a 100 m x 100 m (1 Ha) cell size. A comparable Estimated Pre-1750 (pre-european, pre-clearing) raster dataset is available: - NVIS4_1_AUST_MVG_PRE_ALB. State and Territory vegetation mapping agencies supplied a new version of the National Vegetation Information System (NVIS) in 2009-2011. Some agencies did not supply new data for this version but approved re-use of Version 3.1 data. Summaries were derived from the best available data in the NVIS extant theme as at June 2012. This product is derived from a compilation of data collected at different scales on different dates by different organisations. Please refer to the separate key map showing scales of the input datasets. Gaps in the NVIS database were filled by non-NVIS data, notably parts of South Australia and small areas of New South Wales such as the Curlewis area. The data represent on-ground dates of up to 2006 in Queensland, 2001 to 2005 in South Australia (depending on the region) and 2004/5 in other jurisdictions, except NSW. NVIS data was partially updated in NSW with 2001-09 data, with extensive areas of 1997 data remaining from the earlier version of NVIS. Major Vegetation Groups were identified to summarise the type and distribution of Australia's native vegetation. The classification contains different mixes of plant species within the canopy, shrub or ground layers, but are structurally similar and are often dominated by a single genus. In a mapping sense, the groups reflect the dominant vegetation occurring in a map unit where there are a mix of several vegetation types. Subdominant vegetation groups which may also be present in the map unit are not shown. For example, the dominant vegetation in an area may be mapped as dominated by eucalypt open forest, although it contains pockets of rainforest, shrubland and grassland vegetation as subdominants. The (related) Major Vegetation Subgroups represent more detail about the understorey and floristics of the Major Vegetation Groups and are available as separate raster datasets: - NVIS4_1_AUST_MVS_EXT_ALB - NVIS4_1_AUST_MVS_PRE_ALB A number of other non-vegetation and non-native vegetation land cover types are also represented as Major Vegetation Groups. These are provided for cartographic purposes, but should not be used for analyses.

The current NVIS data products are available from http://www.environment.gov.au/land/native-vegetation/national-vegetation-information-system. ## **Purpose** For use in Bioregional Assessment land classification analyses ## **Dataset History** NVIS Version 4.1 ------------------------- The input vegetation data were provided from over 100 individual projects representing the majority of Australia's regional vegetation mapping over the last 50 years. State and Territory custodians translated the vegetation descriptions from these datasets into a common attribute framework, the National Vegetation Information System (ESCAVI, 2003). Scales of input mapping ranged from 1:25,000 to 1:5,000,000. These were combined into an Australia-wide set of vector data. Non-terrestrial areas were mostly removed by

This is a polygon coverage representing the Western Australian wetlands cited in the "A Directory of Important Wetlands in Australia" Third Edition (EA, 2001), plus various additions for wetlands listed after 2001. The full dataset is collated by the Australian Government Department of the Environment from various datasets supplied by the relevant State agencies. A subset of the WA Important Wetlands are listed as RAMSAR wetlands.

Interim Biogeographic Regionalisation for Australia (IBRA) version 7.1 represents a landscape based approach to classifying the land surface of Australia. 89 biogeographic regions and 419 subregions have been delineated, each reflecting a unifying set of major environmental influences which shape the occurrence of flora and fauna and their interaction with the physical environment across Australia and its external territories (excluding Antarctica). IBRA Version 7.1 data consists of two datasets. IBRA regions, which is a larger scale regional classification of homogeneous ecosystems, and subregions, which are more localised. IBRA Version 7.1 is a minor update to IBRA Version 7.0 to coincide with the release of the CAPAD 2024 dataset to more closely conform to the Geoscience Australia (GA) Australia’s Land Borders (see https://pid.geoscience.gov.au/dataset/ga/140044). IBRA Version 7.0 regions and subregions are realigned to the updated GA jurisdiction borders in some locations. For example, the Victorian Riverina subregion runs along the NSW-Vic border, the border in this area is updated to better align with the river. IBRA Version 7.1 restores the South Bruny land mass portion of Bruny Island (Tas) back to the Southern Ranges region Southern Ranges subregion to which it was assigned in IBRA Version 6.1. The whole of Bruny Island was incorrectly assigned to the South East region and Tasmanian South East subregion in IBRA Version 7. IBRA Version 7.1, aligns Ball’s Pyramid (south of Lord Howe Island) to other coastal data sources.
