Abstract

The absence of utilization-plan for the plantations of eucalypt in Kurdistan region created the necessity of exploring the wood and its validity for sawn lumber production. Twenty two trees of Eucalyptus camaldulensis Dehnh. were cut, bucked, and sawed for boards with different thicknesses. Boards were dried once in summer; second in winter under three methods of drying in each of the two seasons. Flat sawing (FS) and quarter sawing (QS) were tested. Board volumes were measured and classified into different categories according to board dimensions. Total income for the two methods of sawing and for the different seasons was estimated. Results indicated that merchantable quality sawn boards can be produced from the species by using certain drying techniques. FS and QS were suitable but boards produced were different in quality and quantity. Waste of sawing was higher in case of QS technique. Almost all of wide boards (>16 cm) belonged to (FS). Equal log volume (2.5 m³) resulted in 1.81 m³ and 1.35 m³ of sawn boards by FS and QS respectively. Because of lessen wastes and better quality, FS offered 48% more income.
