Carbon sequestration potential of spotted gum (Corymbia citriodora subspecies Variegata) in South East Queensland, Australia

Abstract

The objectives of this study were to determine the carbon sequestration potential of spotted gum forest plantation in the South East Queensland region and to determine the suitability of the whole area to carbon sequestration endeavour. This information is indispensable to stakeholders when considering land use options particularly carbon sequestration. A process-based model and geographic information system were employed in the process. The site has a potential biomass production of 1422–2329 ton/ha with the carbon dioxide equivalent range from 2539 to 4157 ton/ ha in 100 year of rotation period. The maximum mean annual growth of 19.98m3 ha1 was estimated in the Great Sandy sub-region while the lowest value of 11.46m3 ha1 was predicted in South Burnett sub-region. The findings indicated that the whole region has a high potential carbon sequestration capability but requires further spatial suitability and economic analysis.
