Widespread salvage logging for 30 years after the 1939 fires had huge ecological impacts. It favoured cutting fire damaged (but living) larger diameter trees. After a fire, generally there will be a return of a healthy multi-staged forest required to provide maximum habitat. Bushfires usually leave a high level of this structural complexity in the forest. Wildfires typically consume less than 10% of the wood. However, salvage logging (clearfelling) will convert the forest to an even aged, plantation-like structure.
