  • 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 proposed layer for East Gippsland's modelled old-growth forest derived from both vector and grid based analysis using disturbance data that post dates the source old-growth analyses. 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.

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

  • WUP for years 2013/14 - 2015/16 WUPs incorporate all commercial timber harvesting activities, (not domestic firewood) and minor produce operations where tree felling is required, associated access roading, and significant stand management operations (including thinning, reforestation and treatment of unmerchantable trees) managed or undertaken by DEPI. WUPs may incorporate other operations which involve vegetation disturbance and soil removal as determined by the Level 1 Manager. The TUP essentially superseded the WUP after VicForests became responsible for these operations.

  • 1:250,000 Groundwater Flow System layer converted to a grid based on DEM25

  • This layer contains restricted taxa records from the Victorian Biodiversity Atlas (VBA). Record locations have been denatured to a 1 minute polygon grid to enable genaral data access. These records are held seperately from, and should be used in conjunction with VBA_FAUNA/FLORA25/100. VBA records are restricted when deemed by the Department to be vulnerable to collection, harvesting or disturbance. The main attributes in this layer are taxon name, conservation status, count, and year of record. The VERS_DATE column identifies the currency of the data. The FFG field has been updated to reflect the 2021 FFG Act amendments, and the Victorian Advisory List (VICADV) is now obsolete.

  • 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.

  • 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 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 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
