  • 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.

  • MOG2009 is now OBSOLETE Please refer to FORESTS.MOG for updated extent. Old growth forest was defined under the Code of Practice 2007 as forest which contains significant amounts of its oldest growth stage in the upper stratum usually senescing trees and has not been subjected to any disturbance, and if so the effect of which is now negligible. This data layer contains modelled old-growth forest which was updated by the department in 2009 in consideration of historical timber harvesting and fire disturbances. Previous old growth base layers used different sources to establish MOG 2009. The base layer in the western part of the state was og100 and the base layer for the eastern Victoria, other than East Gippsland FMA was mog2003. The base layer for East Gippsland FMA was mog100-2007eg. In the process to develop MOG2009, the previous old growth base layers were updated where necessary with the following input datasets : Lastlog25 (current to Jun 2013-14), lastburnt100 (current to the end of the 2009-10 fire season), fire_sev2006, fire_sev2007ap, fire_sev2007sp and fire_sev2009_poly (in East Gippsland FMA only). The old growth forests in the base layers were 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 considered to be reliable (definitive) at scales less than 1:100,000. The old growth polygons should be treated as modelled information and whilst care has been taken in developing this layer, there is no guarantee that the information has been confirmed through extensive field checking. While some limited validation of Old growth polygons has been carried out in most studies, significant levels of field checking were undertaken in the mapping of analysis input datasets.

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

  • This layer summarises VBA fauna records against a standard grid of 5 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 10 and 1 minute grids are also available in related datasets. VBA records with a spatial accuracy worse than +/- 4.5 km are excluded from this layer.

  • This layer contains modelled old-growth forest which has been updated with forest harvesting and fire. The base layer used in western part of the state is og100 which was updated by lastburnt100, lastlog25 and boundaries of the 2006 Grampians fire from ECC. The base layer for the eastern part of the state is mog2003 updated by lastlog25 & lastburnt100. The old-growth forests in the base layers were identified to meet the Victorian definition of old-gwoth forest based on a set of modelling criteria, rules and input datasets. The data is not reliable at scales less than 1:100,000. Old-growth polygons have not been confirmed through field checking and the reliability of modelled old-groth stands have not been assessed.

  • 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.

  • 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.

  • 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.

  • Contains polygon features delineating and describing Regional Forestry Agreement boundaries. All arc features are identified and coded according to the AS2482 standard.

  • Obsolete. NVIM data. 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 2A of this data set is used to determine the Strategic Biodiversity Value of potential loss for the purposes of the permitted clearing regulations.
