Estimation of net above ground biomass in forest ecosystems by non-destructive means requires the development of allometric equations, to allow prediction of above ground biomass from readily measurable variables such as Diameter at Breast Height (DBH). Equations of this type have not been well developed for trees of Wof-Washa Forest. In the present study, trees of two species namely Juniperus procera and Podocarpus falcatus, with three diameter classes (30-50 cm, 51-70 cm and 71-100cm) with the aim of developing appropriate allometric equations were characterized. Each species considered separately, there was significant variation among the slopes and elevations of the equations obtained for each. The allometric equation that was obtained for the two species had significant (P> 0.000) fit for linear model. The difference between DBH-biomass relationships among these species can be attributed to differences in the distribution of biomass among trunk-plus-large-branches, secondary branches and leaves, and also woody tissue density. Comparison of these results with those obtained using a previously published allometric model revealed significant differences with biomass estimation. It is believed that previously published allometric model corresponding to above ground biomass in dry forests may bear errors, and propose the new equations to be used in the future for the two species and that other one have to become developed for the remaining species.
