  • This is one of a series of restricted layers that identifies the nesting areas for threatened Egret species and records areas where breeding was confirmed and also identifies areas where breeding may have occurred in the past. Where breeding has occurred the year and month where available are listed. The site name is also given where known.

  • This dataset is a simplified and generalised version of the NV2005_EXTENT dataset. The parameters of the simplification and generalisation have been set to produce a a product suitable for mapping at scales between 1:400000 and 1:2000000

  • Obsolete - replaced by NVR2017_CONDITION. 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.

  • This layer is now Obsolete. This layer is now replaced by TRP which is the Gross extent and location of coupes on an approved Timber Release Plan for the period 13 January 2011 onward. There is also the TRP_20100107 & TRP_20100813 versions which is in the Obsolete schema. Compiled from Timber Release Plan (TRP) shapefiles: - all approved harvesting, and roading areas across VicForests Planning Area - Central, Benalla-Mansfield, Central Gippsland and Dandenong FMA's 2006/07 - 2011/12 TRPs - East Gippsland and North East FMAs 2009/10 - 2014/15 TRPs

  • 1:250,000 Groundwater Flow System layer converted to a grid based on DEM25

  • This is one of a series of restricted layers that identifies the nesting areas for threatened Egret species and records areas where breeding was confirmed and also identifies areas where breeding may have occurred in the past. Where breeding has occurred the year and month where available are listed. The site name is also given where known.

  • This layer summarises VBA flora records against a standard grid of 1 degree 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 10 and 5 minute grids are also available in related datasets. VBA records with a spatial accuracy worse than +/- 1 km are excluded from this layer.

  • This replaces SPECIES_HABITAT_V4_HPNV, which had replaced V4_HDNV and V4_HINV. This data series is a set of spatial maps describing importance of suitable habitat within the current extent of native vegetation for some species. These species are rare or threatened and their habitat is described as either dispersed or highly localised (ie remaining habitat within Native Vegetation is either greater than or less than 2000 ha respectively based on IUCN categorisation). These models have been developed for use in the native vegetation removal regulations. Thresholds have been applied to the maps because lower likelihood areas do not receive species-specific consideration in the assessment process. Habitat importance is ranked for dispersed species; for highly localised habitats it is equal across the map. The values stored in these data are used to calculate habitat value and offsets under the native vegetation removal regulations (2017). Note that for dispersed species the values stored in these data must be divided by 100 to calculate the habitat importance score. Dataset Series Naming: NVR2017_HIM[taxa_id]_vg94.tif where taxa_id is based on VBA taxon_id vg94 is the projection vicgrid94.

  • Box-Ironbark Forests and Woodlands Investigation Final Recommendations - for the Environment Conservation Council. The Minister, under Section 17 of the Environment Conservation Council Act 1997 required the Environment Conservation Council to carry out an investigation of Victoria’s Box-Ironbark Forests and Woodlands occurring on public land in northern Victoria. The area investigated was the box-ironbark ecosystem stretching from the Grampians in the west to Wodonga in the north-east.

  • Obsolete. This is the updated version of NVR2013_SBS_V2. 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. For use on the native vegetation permitted clearing regulations, the Strategic Biodiversity Value ranking is converted to a score that enables the strategic importance of different locations to be directly compared in numerical terms (e.g. such that a location with a score of 0.4 can be considered to be twice the strategic value of a location with a score of 0.2). Version 3 of this data set is used to determine the Strategic Biodiversity Value of potential loss for the purposes of the permitted clearing regulations.
