  • This version of the areas of the cultural heritage sensitivity dataset (ACHS) does not contain any attribute information. This dataset contains a spatial representation of "Areas of Cultural Heritage Sensitivity" as specified in Division 3, Part 2 of the Aboriginal Heritage Regulations 2018. Areas of cultural heritage sensitivity are areas that are either known to contain, or are likely to contain Aboriginal cultural heritage places and objects. These areas, which include various landforms within Victoria, are defined in the Aboriginal Heritage Regulations 2018. This polygon dataset is a representation of those areas as defined in the Regulations. The polygon features within the dataset have been derived from several sources, including geological and hydrological data. Note: This dataset is based on the best available information and should be used in conjunction the information contained in Division 3, Part 2 of the Aboriginal Heritage Regulations 2018. This data is under active revision to improve the representation as better quality source data becomes available.

  • This dataset delineates Victorian biogeographic regions (Victorian bioregions) that capture the patterns of ecological characteristics in the landscape, providing a natural framework for recognising and responding to biodiversity values. Victorian bioregions form part of the national framework for the terrestrial environment, the Interim Biogeographic Regionalisation for Australia (IBRA). The boundaries are aligned with pre-1750 ecological vegetation class boundaries mapped at 1:100,000. The dataset upgrades the VBIOREGION250 dataset which was primarily based in 1:250,000 landsystem boundaries.

  • This layer summarises VBA fauna records against a standard grid of 10 degrees longitude/latitude (GDA94). Any VBA taxa record with its centre in a cell is counted as a record for that cell. The number of times a taxon has been recorded in a cell is collated in the RECORDS column. The first date and last date that a taxon has been recorded in a cell are also summarised. VBA data summarised against 5 and 1 minute grids are also available in related datasets. VBA records with a spatial accuracy worse than +/- 9 km are excluded from this layer.

  • This replaces NVR2013_LOCRISK_V2. This dataset describes the native vegetation location category for all land in Victoria for the purposes in the native vegetation removal regulations. Location category is calculated from a set of spatial models describing the importance of suitable habitat within the current extent of native vegetation for many rare or threatened species, and the location of an endangered Ecological Vegetation Class or sensitive coast or wetland area.

  • Polygons defining Ramsar wetland areas in Victoria. The Ramsar Convention of Wetlands of International Importance, to which Australia is a signatory, requires contracting parties to designate wetlands of international significance within their territory for listing under the convention. This layer is based on RAMSAR100 but has been realigned and updated to improve its accuracy. It has been updated to match current VICMAP parcel, road, hydro and water area data as well as using high-resolution digital aerial photography to improve its precision to 1:25 000.

  • Obsolete data, replaced by NVR2013_SBS_V3. The NaturePrint Strategic Biodiversity Values dataset is an objective, comprehensive and spatially explicit view of strategic biodiversity values. This dataset does more than just recognise the presence of significant biodiversity characteristics at each site, it identifies the value of a site relative to the value of all other Victorian locations. DEPI's NaturePrint initiative coordinates the development and application of datasets and techniques to enable this view. Ideally, these analyses would be based on complete information on all biodiversity and relevant ecological considerations at all places in Victoria. Given this level of information is not available, the NaturePrint approach relies on robust modelling and extrapolation from available primary data.

  • Structural vegetation mapping of forest in Victoria based on the Land Conservation Council (LCC) vegetation classification scheme. The layer is independent of land tenure and is a combination of existing data from multiple sources (predominantly LCC) and primary mapping based on satellite image interpretation. Using histoirc 1:63,360 forest maps as a source.

  • This dataset has been developed for use by local government and Department of Sustainability and Environment (DSE) staff who are assessing planning permit applications to clear native vegetation that are classified as low impact. Site-based data is generally not available for permit applications assessed using the low impact pathway. This layer allows a local government or DSE officer to determine the default conservation significance of remnant patches without the need to collect site-based data. The data layer has been created using modelled vegetation type and quality, available best and remaining habitat models and spatial information on other attributes. This dataset does not reflect any requirements of the Flora and Fauna Guarantee Act 1988 or Commonwealth Environment Protection and Biodiversity Conservation Act 1999. This dataset has been developed for a particular use scenario.

  • Obsolete. Site condition aims to reflect three components - composition, structure and function. In practice, condition is measured through the prism of lifeforms, their cover and species diversity. Measuring the condition of native vegetation recognises that most remaining native vegetation in Victoria has been subject to some disturbances, such as historical land use, grazing or weed and pest animal invasion, and is subsequently reduced in condition; vegetation types vary spatially and temporally; circumstances fluctuate (e.g. seasons, natural disturbance events); degradation and rehabilitation occur; and naturalness is valued.
