The STATE-WIDE OLD GROWTH SURVEY GRID and STATE-WIDE OLD GROWTH SURVEY GRID CENTROIDS dataset were developed to assist the verification of the presence or absence of old growth forest in Victoria. The STATE-WIDE OLD GROWTH SURVEY GRID dataset is a 1-hectare square grid which has been created in ArcGIS pro 2.3. STATE-WIDE OLD GROWTH SURVEY GRID CENTROID is the centre of each 1-hectare square grid cell. This is polygon layer consisting of 100mX100m squares covering the extent of Victoria. Within each square is a centroid that is used as a survey point for undertaking tree assessments. The centroids are located within a square that has a bounding box with coordinates that are divisible by 100. So a centroid with coordinates 2,616,250m 2,400,050 is within a square with left X = 2,616,200 and right X =2,616,300, bottom Y = 2,400,000 and top y = 2,400,100. For further information on old-growth verification please refer to the Procedure for Identifying Old Growth Forest in Victoria.

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 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.

The STATE-WIDE OLD GROWTH SURVEY GRID dataset is a 1-hectare square grid which has been created in ArcGIS pro 2.3. STATE-WIDE OLD GROWTH SURVEY GRID CENTROID is the centre of each 1-hectare grid cell. The extent of this data is aligned with the Modelled Old Growth (MOG) dataset and 400m buffered. For further information on old-growth verification please refer to the Procedure for Identifying Old Growth Forest in Victoria.

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 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.

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.

This dataset is a modified version of TREE100 which has been intersected with the 25 thou mapsheet index to break up the larger polygons.
