To determine of biometrical (fiber length, fiber diameter, lumen and cell wall thickness), physical (density and volumetric swelling), chemical (amount of extractives, cellulose, lignin and ash) and mechanical (modulus of rupture, modulus of elasticity, compression strength parallel to grain, compression strength perpendicular to grain, shear parallel to grain, janka-hardness and nail withdrawal) properties of eucalyptus camaldulensis wood from Sistan region five trees were selected and evaluated. The results showed that fiber dimensions in tree trunk, from pith to bark and decreased from bottom to top. The volumetric swelling variation decreased in radial axis from pith to bark and in longitudinal axis from bottom to the top. There were no significant different at 5 percent statistical error level between the cellulose and ash content values in heartwood and sapwood, respectively. On the other hand, significant difference at 5 percent statistical error level was observed between lignin and extractives values in heartwood and sapwood, respectively. Also, mechanical properties of wet and dry samples were determined. The results indicated that the mechanical properties of wet samples were lower than dry samples, significantly.
