Estimates of biomass are important for understanding savanna structures and assessing the functions of forest ecosystems. Methods of determining biomass can be done directly by measuring biomass, this involves harvesting a number of bushes of all sizes, oven drying the material and weighing them. Another common method is using allometric equations, a method which is being adopted in Namibia and considered the most appropriate today. A  study conducted by Smit et al. 2015 quantified biomass on the ground on selected bush thickened farms using the BECVOL model.
