This study aimed to investigate the amount of above ground biomass of Eucalyptus camadulensis in Garbayegan Fasa ,the province of Fars in Iran. For this purpose three normal and healthy eucalypt trees with the diameter between 20 to 40 cm randomly were cut from Kowsar research station of even age plantation of 16 years old and spacing 3 by 3 m. that is located in Garbayegan Fasa. All branches and leaves were removed from all boles and,then three discs were separated from 1%, 50% and 75% of total tree height of each trunk.The remained trunks were logged in 1m.then marked and weighted for biomass determination. Trunk average moisture content was calculated using wood specimens that were taken from each disc of all trees. Leaves, barks and branches weighted both in wet and dry situation. By regard to the results the average critical and oven dry wood density in Garbayegan Fasa was 0.565 g/cm3, and trunk biomass 136.7 ton/ha, meanwhile the weight of leaves and bark were obtained 72.5 and 39.9 ton/ha respectively. All in all, biomass in total was reached 249.1 ton/ha.
