Abstract

Above ground dry biomass was estimated for a 23 years old Pinus elliottii stand, located at Rio Branco do Sul, State of Paraná, Brazil. Stem, branches and needles dry biomass were estimated separately. The estimated total above ground dry biomass was composed by 85 % of stem, 10 % of branches and 5 % of needles, respectively. The adjusted equation for estimation of total dry biomass as a function of the diameter at breast height (DBH), showed a coefficient of determination (R²) of 0.91 and a standard error in percentage (Sxy%) of 11,98 %. Among the tested models for estimating the different portions of tree dry biomass as a function of DBH, the stem biomass equation was the one that showed the best results.
