Supplemental Information

History: Original Old-growth forest projects undertaken during 1990-97, generating an output file called OG100, defining modelled old-growth forest across RFA areas in Victoria. As a result of updated disturbance data inlcuding updated and modified logging history data, and also the Jan-Feb 2003 Alpine Fire Severity mapping classification (FIRESEV03), the impact on old-growth was identified as an issue. MOG2003 is derived from OG100 overlayed with updated logging information and fire severity classes. The fire severity class 1 (crown burn) impacts on all forest types, whereas class 2 (severe crown scorch) impacts on ash forest types only. So old-growth forest in these classes was seen to be removed from the old-growth class, as was modelled old-growth with clearfell harvesting history. Relationship to other Datasets: The old growth forest modelling process used to derive this layer uses key disturbance datasets, including SFRI25VE, GRAZE100, LOGHIST100, LOGHIST250, FIRE100_XY, AGCLEAR100 and mining layers, and vegetation attributes from the GSTAGE100, EVC100, SVEG100 layers. Current Design Issues: The old-growth modelling process is undertaken on a study areas basis with which each study applying different rules and inputs. It is possible that adjacent study areas within one tile may have edge matching problems. Future Design Issues: The current dataset does not assign an accuracy level to any polygon. This may need to be accomodated as areas of old-growth forest are increasingly verified in the field.
