Abstract

Abstract: Allometric equations estimating carbon stock of Gardenia aqualla and Gardenia ternifolia stands in Cameroon have been developed. The sample consists of 35 individuals of Gardenia aqualla and 35 individuals of Gardenia ternifolia. These individuals were cut, measured and weighed entirely and the data acquired was used to build predictive models of biomass as a function of diameter at breast height. Adjusted coefficients of determination, residual standard error, root mean square error and Akaike's information criterion were used to choose the best models. Linear, power, exponential and logarithmic functions were fitted for aboveground biomass using diameter at breast height as the independent variable. The best fit model for estimation of total aboveground biomass (TAGB) was in the form of a power function TAGB = 0.289D1.168 (Gardenia aqualla) and TAGB= 0.279D1.052 (Gardenia termifolia). This study indicated that, Gardenia aqualla showed higher AGC (59.98 Mg C.ha-1) compared to Gardenia ternifolia (50.95 Mg C.ha-1). Gardenia aqualla (220.12 Mg CO2 .ha-1) sequestered CO2 more than Gardenia ternifolia (186.98 Mg CO2 .ha-1). These developed equations will be useful tools to assess the potential for carbon sequestration in Gardenia aqualla and Gardenia ternifolia stands and represent key information for scaling up biomass estimates for the REDD + context. This study showed that the Gardenia genera plays a role as a carbon sink.
