Description: The sawtimber potential of 12-year-old Eucalyptus saligna Sm. trees grown in Maui, Hawaii, was studied by using simple field techniques. Lumber manufactured from the trees was predominantly of low grade, but had lower average density than wood from older trees, and therefore was more desirable. Logs end-split badly, and sawed with the usually encountered amount of difficulty due to growth stress that averaged 1,350 psi per log. The wood shrank moderately in drying, but lumber degrade was not serious. Bending strength, except for modulus of elasticity, was high for the specific gravity. The wood nailed, machined, and glued reasonably well, but did not accept preservative when pressure treated.

Keywords: Eucalyptus saligna; Hawaii; young growth; wood properties; lumber grading
