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.

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.)

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 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 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.

This layer summarises VBA flora 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.

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. To contribute to assessments of the significance of native vegetation at different locations, and of the amount of potential loss. Version 2A of this data set is used to determine the amount of potential loss for the purposes of the permitted clearing regulations.

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.

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 revision to include additional listed communities and a new version is expected during 2022.
