The proposed layer for East Gippsland's modelled old-growth forest derived from both vector and grid based analysis using disturbance data that post dates the source old-growth analyses. Areas delineated as old growth forest are identified to meet the Victorian definition of old-growth forest based on a set of modelling criteria, rules and input datasets. The data is not reliable at scales less than 1:100,000 (ie 1:25,000), not all old-growth polygons have been confirmed by field checking and the reliability of the modelled linework has not been verified.
This layer summarises VBA flora 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.
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.
This replaces NVR2013_COND_V2 and _V2A. 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.
Native Vegetation - Modelled 1750 Ecological Vegetation Classes (with Bioregional Conservation Status)
This is a derived dataset that delineates the current Bioregional Conservation Status of EVCs within the modeled 1750 EVC dataset. The dataset is derived from a combination of both Victorian bioregions (VBIOREG100) and the modeled 1750 EVC dataset (NV1750_EVC), with an assigned conservation status on the basis of unique Bioregion EVC units. The dataset underpins the implementation of Victoria's Native Vegetation Management Framework, and the preparation of Regional Vegetation Plans in addition to other biodiversity planning. The dataset requires upgrading when either of the two input datasets change. Note erratum under Data Quality-Completeness-Classification
Native Vegetation - Modelled 2005 Ecological Vegetation Classes (with Bioregional Conservation Status)
This is a derived dataset that delineates the Bioregional Conservation Status of EVCs. (NV2005_EVCBCS) . The dataset is derived from a combination of Victorian bioregions (VBIOREG100), Pre 1750 EVCs (NV1750_EVC) and the current version of Native Vegetation Extent (NV2005_EXTENT). Bioregional conservation status and geographic occurrence are applied to unique Bioregion-EVC units. The dataset underpins the implementation of Victoria's Native Vegetation Management Framework, and the preparation of Regional Vegetation Plans in addition to other biodiversity planning. The dataset requires upgrading when any of the three input datasets change. (Note that this dataset is stored in two Spatial Data Storage Environments within DSE - Arc/Info tiled libraries and Oracle/SDE single data layer. This metadata describes the Arc/Info dataset. The Oracle/SDE dataset is slightly different in that all non-vegetation classes are excluded from the data (ie. Bare rock, sand, non-native vegetation etc.) also the attributes include attributes expanded from Look Up Tables. These have an X_ prefix in the name.)

Victorian Biodiversity Atlas fauna records (unrestricted) for sites with moderate to low spatial accuracy
This layer contains a snapshot of fauna taxa records from the Victorian Biodiversity Atlas (VBA) (including most threatened taxa). The main attributes in this layer are survey id, survey location, date, time, locational accuracy, taxa recorded, counts, observation type, survey type, collector, and reliability of the record. The VERS_DATE column identifies the currency of the data. Although this is a point layer, the actual accuracy of the site can range from +/- 500m to +/- 10 km. The FFG field has been updated to reflect the 2021 FFG Act amendments, and the Victorian Advisory List (VICADV) is now obsolete. This layer excludes restricted taxa records. These records are contained in the related (but restricted) dataset VBA_FAUNA_RESTRICTED. Public users wishing to view the general location of these records should refer to the related dataset VBA_RESTRICTED_1M.
Strategic Biodiversity Values (SBV) is one of NaturePrint's decision-support products. It combines information on important areas for threatened flora and fauna, levels of depletion, connectivity, vegetation types and condition to provide a view of relative biodiversity importance of all parts of the Victorian landscape. This integrated information is important because decision-makers need access to an objective, comprehensive and spatially explicit view of the importance of biodiversity assets to enable comparison of locations across Victoria.
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.
Contains polygon features delineating and describing Regional Forestry Agreement boundaries. All arc features are identified and coded according to the AS2482 standard.
