  • 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

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

  • 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 replaces NV2010_EXTENT_V3. The extent of native vegetation is the area of land covered by native vegetation. A comprehensive and accurate modelled picture of the distribution of native vegetation remaining across Victoria helps to efficiently invest in biodiversity programs, regulate land and resource use, and understand where further assessment of potential actions may be required or desirable.

  • 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 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 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.

  • 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 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.

  • Spatial dataset showing research sites within and surrounding Wilsons Promontory. Each mapped area provides details of the research project or report that studied that location.
