Modelled old-growth forest boundaries post-2003 fire season (MGA zone 55 only)

This layer contains identified areas of modelled old-growth forest derived from both vector and grid based analysis using disturbance data that post dates the source old-growth analyses. Alpine Fire Severity Mapping (2003) and Logging history records that conflict with Old-Growth Forest (OG100) have been reclassified as not old-growth forest. 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.
