The objective of this study determination total storage of carbon content weight  for three tree species namely Eucalyptus gomphocephala, Casuarina equisetifolia and Casuarina glauca during 2019. On this concerning carbon content decreased in available merchantable portions which decreased carbon content as environment balance region and economic value. E. gomphocephala and C. equisetifolia have recorded total tree biomass values (378.49 and 327.95 kg/tree) respectively which were significantly higher when compared to C. glauca (148.95 kg/tree). On the other hand evaluating total weight of carbon content on merchantable fewer portions had stayed on the same area. E. gomphocephala and C. equisetifolia had significantly enhanced carbon content weight values on merchantable fewer portions (146.45 and 138.34 kg/tree) respectively compared to C. glauca (32.99 kg/tree) more fourfold increment approximately. The investigated study was carried out at the Experimental Farm of El-Kassasin Horticulture Research station, Horticulture Research Institute, Agriculture Research Center, Giza, Egypt.
