The trees of River Red Gum in Damascus- Daraa Road are in a good height, diameter and growth, so that we aimed to study some of the physical 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 height of the tree.

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

• It is hard, in which the density was 0.63 g/cm3, and this means that it is resistant to mechanical stress and sutable for using in building and engineering constructions.
• The shrinkage is high.
• As for the variance, there are significant effects of tacking masses from tree on the physical properties of the wood.
