The aim of this work was to assess the influence of different section lengths on the determination of eucalyptus treestem (with bark) volumes and its implications in forest inventory procedures. The 40 Eucalyptus grandis trees used, all from themunicipality of Viçosa, Minas Gerais state, were 77 months old. The volume of the stems (with bark), whose maximum diameter was3,0 cm, was obtained through the Smalian formula, with sections 1.0, 2.0 and 3.0 m long. Longer sections lead to overestimations ofthe volume of the trees’ basal part and, consequently, of their total volume. Different statistical tests led to different conclusionsregarding the similar volume estimates resulting from experiments using different section lengths4. Volumetric equations adjusted withlonger sections may introduce bias errors in forest inventory procedures. |
