  • 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

  • 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 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

  • 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.

  • Polygons delineating vegetation units defined by the Land Conservation Council (LCC). Forest species and structure are defined for each LCC Study Area.

  • Obsolete - replaced by NVR2017_LOCATION. This is the updated version of NVR2013_LOCRISK_V1. This dataset describes the native vegetation location risk for all land in Victoria for the purposes of use in the native vegetation permitted clearing regulations. Location risk is calculated on the basis of a set of spatial models describing the importance of suitable habitat within the current extent of native vegetation for many rare or threatened species.

  • 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.

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 identified areas of modelled old-growth forest derived from both vector and grid based analysis. 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.

  • The Biodiversity Conservation Strategy for Melbourne's Growth Corridors (BCS) prepared as part of the Melbourne Strategic Assessment specifies that salvage and/or translocation of plants and animals may be required before the removal of native vegetation or habitat for urban development in Melbourne's growth corridors. This dataset identifies land parcels under the Biodiversity Conservation Strategy that may be subject to the salvage and translocation process, as defined by the Salvage and Translocation Protocol for Melbourne's Growth Corridors (DEPI, 2013). Salvage may be required for the following target species and communities listed under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) and Victorian Flora and Fauna Guarantee Act 1988 (FFG Act): - Spiny Rice-flower, Matted Flax-lily and other grassland plants - Striped Legless Lizard - Seasonal Herbaceous Wetlands (Freshwater) of the Temperate Lowland Plains. Land parcels which contain a set of conditions for each of the above species/communities will trigger a salvage and translocation procedure to be enacted in accordance with the Protocol.
