  • This dataset is a simplified version of TREE100 with areas less than 500,000 sqm deleted and the remaining features generalized using the bendsimplify algorithm with a 100 metre tolerance.

  • 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 above 1:2000000

  • 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.

  • 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 identifies categories of modelled forest categories determined through an analysis of readily available authoritative forest disturbance datasets on public land. The dataset identifies areas likely to contain old-growth forest, amongst other forest categories.

  • This dataset is a simplified version of TREE100 with areas less than 20,000,000 sqm deleted and the remaining features generalized using the bendsimplify algorithm with a 5000 metre tolerance.

  • 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

  • Under the Melbourne Strategic Assessment program, liabilities are calculated through the use of the `Environment Mitigation Dataset'. This dataset is made up of two sub-sets, the `Environment Mitigation Polygon Dataset' and the `Environment Mitigation Point Dataset' (this dataset). The `Environment Mitigation Polygon Dataset' provides the habitat areas across the levy area, while the `Environment Mitigation Point Dataset' (this dataset) provides the point data for scattered trees. Liability is based on the hectares of habitat and the price for that habitat type, and the number of scattered tree locations and the price for a scattered tree location. A parcel of land, or other area for which a liability is imposed, may have a liability imposed based on the coverage over that land of one or more of the following: > Native vegetation area > Matted Flax-lily habitat area > Spiny Rice-flower habitat area > Golden Sun Moth habitat area > Growling Grass Frog habitat area > Southern Brown Bandicoot habitat area > Scattered tree location Each of these are represented in the `Environment Mitigation Dataset', with the points for scattered tree locations represented in this sub-dataset.

  • This dataset is a simplified version of TREE100 with areas less than 5,000,000 sqm deleted and the remaining features generalized using the bendsimplify algorithm with a 600 metre tolerance.

  • 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.
