The River red gum (Eucalyptus camaldulensis Dehn. ) is found in a lot of places in Syria, and the trees in Damascus- Daraa Road are in  good height, diameter and growth, so that we aimed to study some of the mechanical properties of its wood related to the most important modern uses of this wood in industry.

The study was done over Three trees, and three trunk masses of wood about 70 cm were taken from each tree from the beginning, the breast and the middle of the tree .

The results show that the wood of Rever red gum has the following mechanical properties:

-     The compression strength parallel to grain is medium (39.6 N/mm²), therefore, it is good in industries uses.

-     The bending factor is weak (1.44) , and its coherence is medium  (2.27).

-          The risistance of tensile strength was 40 N/mm² .

-          Hardness (Janka) was 38.3 N/mm².

So that we find out that the wood of River red gum is good and could be considered as a good wood with various uses and this spice is considered one of the promosing trees in our country for afforestration in zones like the stydy zones.

As for the variance, ther are significant effects of tacking masses from tree on the physical and mechanical properties of the wood.
