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

  • 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.

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

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

  • 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

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

  • 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 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.
