Carbon storage in afromontane rain forests of the eastern arc mountains of Tanzania: their net contribution to atmospheric carbon

Shear T. H., . and Munishi P. K. T., . Carbon storage in afromontane rain forests of the eastern arc mountains of Tanzania: their net contribution to atmospheric carbon. pp. 78-93. ISSN 0128-1283

With the increasing concern about rising atmospheric carbon dioxide concentration and its implications for global climate the role of terrestrial vegetation and especially tropical forest management have received attention as a means of mitigating carbon (C) emissions. Thus inventorying carbon pools in these ecosystems has become important for understanding the global C budget. Tree dimensions wood basic density and analyses of soil C concentration were used to quantify the biomass and C pools of the Eastern Arc Mountains of Tanzania. Tree C density was estimated as product ofwood volume basic density and proportion ofC in wood. Soil Cdensity was estimated as product of soil volume bulk density and per cent C. Tree biomass was 1055 35 and 790 20 t ha-1 for the Usambaras and Ulugurus respectively. These aggregated to 517 17 t ha-1 C in the Usambaras and 388 10 t ha-I in the Ulugurus. The soil organic C density was 418 100 t ha-1 in the Usambaras and 295 53 t ha-1 in the Ulugurus. Mid-altitude plant communities had higher C storage potential compared with high altitude plants. This capacity for C storage population pressure and the extensiveness of these forests in the region make their conservation a global significance for C emission mitigation.

Abstract

With the increasing concern about rising atmospheric carbon dioxide concentration and its implications for global climate the role of terrestrial vegetation and especially tropical forest management have received attention as a means of mitigating carbon (C) emissions. Thus inventorying carbon pools in these ecosystems has become important for understanding the global C budget. Tree dimensions wood basic density and analyses of soil C concentration were used to quantify the biomass and C pools of the Eastern Arc Mountains of Tanzania. Tree C density was estimated as product ofwood volume basic density and proportion ofC in wood. Soil Cdensity was estimated as product of soil volume bulk density and per cent C. Tree biomass was 1055 35 and 790 20 t ha-1 for the Usambaras and Ulugurus respectively. These aggregated to 517 17 t ha-1 C in the Usambaras and 388 10 t ha-I in the Ulugurus. The soil organic C density was 418 100 t ha-1 in the Usambaras and 295 53 t ha-1 in the Ulugurus. Mid-altitude plant communities had higher C storage potential compared with high altitude plants. This capacity for C storage population pressure and the extensiveness of these forests in the region make their conservation a global significance for C emission mitigation.
