Determining Drying Characteristics of Plantation-Grown Eucalypt Timber for Resource Assessment and Improvement
Timber from mature and native forest regrowth eucalypts in Australia has traditionally been air dried, steam reconditioned when below fibre- saturation moisture content and then kiln dried. Most eucalypt species grown in plantations produce wood of lower density than from native forest regrowth but drying for high product quality is not always faster; often drying degrade is increased. The product potential of plantation-grown eucalypt timber is often limited and drying costs become a major factor in determining the viability of establishing processing operations. Thus determining drying properties and appropriate drying processes is critical. Results from studies designed primarily to assess wood quality provide indications of the drying properties for several species and are used to discuss strategies which may be most effective in drying plantation-grown eucalypts with minimal drying degrade and drying cost. Drying tests using aggressive drying conditions have been undertaken to exacerbate drying degrade and distinguish drying characteristics of wood from trees with different genetic and/or silvicultural treatment. Linking drying performance to resource characteristics can be valuable for planning establishment and improvement in plantation resources.
