Apodytes dimidata E. Mey. Ex Am.,) is tree commonly grown in montane forest between 1200 to 3500 m and widely distributed in East Africa. It is used for firewood, for making charcoal and in traditional medicine. Forests are the major source of carbon pools which is released CO2 to atmosphere due to natural and manmade factors. The reliable and accurate biomass assessments for tropical tree species are vital to implement climate change mitigation. The allometric model established by Chave et al. 2014 could not efficiently indicate the AGB in a particular area including the study area. The application of site specific allometeric model is crucial to attain higher level of precision. Therefore, the objective of the finding was to establish site specific allometric model for A. dimidata using semi-destructive sampling methods. The developed models relate AGB with denderometeric variables (DBH, H and WD). From evaluated models only four models were selected based on higher value of R2, SE and AIC and the selected models are significant (p < 0.000). The fourth model is found to be the best model comprising DBH, Height and wood density, with higher R2-adj 0.87 and SE (0.63) and AIC (37). Thus it is suggested that establishment of site specific biomass model are important for better biomass assessment for fulfillment of national and international reporting requirements. The specific allometeric equation developed in this study can be applied in moist forests of the country having similar forest structure for the benefit of the community from carbon trade.
