Abstract: Background: Araucaria angustifolia is the main forest species in southern Brazil, and although the crown has significant biomass, research concerning the underused branches biomass estimation and valuation is scarce. Herein we quantified and modeled individual biomass of branches (B) and aciculated branches (AB) of Araucária, pellets production, and valuated the biomass. Materials and Methods: Based on length and base circumference of 209 branches, we applied a stepwise regression transforming the independent variables, followed by Box-Cox transformation of dependent variable. The valuation of the branch biomass considered different uses, including pellets........
