Potential Difference of Tree Species on Carbon Sequestration Performance and Role of Forest Based Industry to the Environment (Case of Arsi Forest Enterprise Gambo District)

Keredin Temam Siraj, Beka Benti Teshome

This study attempt that to evaluate the potential difference of trees species in carbon sequestration performance. This study has been carried out through biomass estimation and quantification in Gambo district. Identification to species level, and their diameter at breast height (DBH) and height are recorded using ground measurements. The study finding shows that G. robusta, P. radiata, C. lusitanica, P. patulla and E. grandis were ranked 1st, 2nd, 3rd, 4th and 5th in carbon sequestration performance in the same condition respectively. Tree plantation, harvesting it and reforesting that same land has importance in socioeconomic appraisal and environmental values if and only if the forest product is used for last long products, but more than 50% of forest enterprise product after sawmill process is used for fuel wood or leftover in and around the industries. Therefore, local sawmill has to be upgraded and has to reduce the by-products or has to use it for further processing. Government and NGO have to work in the area in providing green energies. In Adama city the concern given to tree species is less than 45% rather more attention is given for shrubs, grass and selection of species is only based on the survival capacity of the species. So this study highlighted the role of each tree species in carbon sequestration and emphasize the need for greater attention to be paid to the selection of trees species in cities to have an appropriate mix of trees species that supports maximum biodiversity and maximizes environmental services.
