  • 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.

  • Polygon layer contains DELWP Land and Fire District Boundaries used for Forest and Fire Management operations.

  • This is a derived dataset displaying the distribution of threatened vegetation communities listed under the Flora and Fauna Guarantee Act (1988). Communities have been matched to one of more Ecological Vegetation Classes (EVCs), and the bioregions in which they occur. Community locations and extent are implied from the extent of the most floristically similar EVCs, and the bioregions in which the EVCs occur. The "distribution" field indicates the range of the listed community within a BioEVC, and the extent to which the range of a community might extend beyond BioEVC boundaries. This dataset is currently under review to include additional listed communities

  • This dataset is created by sketching in the current burnt area from field data and linescan data. This data is updated every time the area of the fire is updated during an incident.The area is captured in the incident mapping system eMap. This data includes both FFMVIC and CFA fires. This data is provided in kml format. The data is only available for the current fire season and shows all fires with a status of Going, controlled or contained (UC1 and UC2) and Safe are included in this feed. . The layer will support fire prevention and suppression activities of DSE, and will be used to generate the FIRE100_{year} fire history datasets. This layer is the source of disturbance datasets used in the analysis of old-growth forest.

  • 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.

  • As a part of a Victorian State Government initiative for Private Forest mapping was established to collect, collate and store forest resource information. The PNF100 layer depicts forest stands interpreted visually from aerial photgraphs and image based mapping. A stand is an area of forest deemed to be homogenous in its species composition, crown cover, crown form, height and distribution for "modified code mapping".

  • 1:100,000 Landuse rasterised to 20m based on VICMAP_ELEVATION_DTM_20M. For more details see the Metadata for LANDUSE100.

  • 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 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 contains identified areas of modelled old-growth forest derived from both vector and grid based analysis using disturbance data that post dates the source old-growth analyses. Alpine Fire Severity Mapping (2003) and Logging history records that conflict with Old-Growth Forest (OG100) have been reclassified as not old-growth forest. 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.
