Allometric Formulas to Predict Haematostaphis barteri Biomass Above and Below Ground in Cameroon

Abstract This study used a destructive approach to develop species-specific allometric equations for H. barteri in Cameroon. A sample of 30 individuals was chopped, measured, and weighed, and six prediction models were created for leaves, branches, trunks, roots, and total above-ground biomass. The best models were chosen using Akaike's information criterion, residual standard error, root mean square error, and adjusted coefficients of determination. The total biomass above ground was ln (B) = 2.832 + 0.981 * ln (dbh2 × H × WD) * (1.0008); the trunks were ln (B) = 1.101 + 0.106 * ln (dbh × WD) * (1.0003); the branches were ln (B) = 0.065 + 0.010 * ln (dbh × WD) * (1.0008); the leaves were ln (B) = 0.065 + 0.010 * ln (dbh2 × H) * (1.0008), and the roots were ln (B) = 0.758 + 0.035 * ln (dbh) * (1.0009). The equations offer important information for scaling up biomass estimations and evaluating carbon sequestration potential in H. barteri stands in Cameroon.
