Modelled Forest Classes 

Alternate title

Purpose

This dataset identifies categories of forest modelled through an analysis of forest resource datasets and readily available authoritative forest disturbance datasets. Forest resource datasets comprise: forest growth stage, ecological vegetation classes and structural vegetation. The forest disturbance datasets datasets comprise: historical and contemporary timber harvesting, grazing, agricultural clearing, mining, wildfire, and fuel reduction burn records. The current geospatial analysis process used by NRE to model old-growth forest has been developed to manage the complex rules and spatial analysis functions that the modelling requires. The analysis process utilises a raster based model and infrastructure initially developed and used in the North East Old-growth Forest Study. The process is undertaken using a 30m cell size and on a 1:100 000 mapsheet basis. The dataset identifies areas likely to contain old-growth forest, amongst other forest categories. The layer has, to date, principally been used to delineate old-growth forest and National Estate areas in two key regions of the State - Gippsland (as defined by the Gippsland Regional Forest Agreement Area) and Midlands-Otways and Portland-Wimmera (as defined by the Western Regional Forest Agreement Area). This layer is one of the key output datasets created from the analysis process used to delineate old-growth forest. The layer has a wide range of applications in both flora and fauna issues.
