Abstract
Eucalypts have a number of characteristics affecting processing and utilization that distinguish them from other woods. The major current interest in the eucalypts is as a fuel. Possible demand as a chemical feedstock, for pulp-wood, panel products, lumber or round timbers should be considered in initial planning and management as a hedge against changes resulting from economic, political or environmental pressures. In general, returns to the grower will be maximized by concentration on maximum yield (cubic volume x specific gravity) for energy, chemical feedstock and pulpwood uses. Specific gravity, as an indicator of strength, is also important for sawn products, round products and some panel products although processing considerations such as internal stresses and drying characteristics are important. Permeability of the wood for penetration by pulping chemicals or preservative solutions is important to pulpwood, and to sawn and round products. Characteristics such as specific gravity and fiber length can be manipulated to a considerable degree by species and seed source selection as well as by silvicultural manipulation. The implications of these and other characteristics for utilization will be reviewed.
