Barbatimão Volumetrics and Hypsometrics Estimates in Northern Minas Gerais

This study sought to assess the barbatimão volume and height estimates generating equations that can be used in the preparation of sustainable management plans from models to estimate the total volume with bark, without bark, of the bark as well as hypsometric relations. The production of bark in the various diameter classes was also compared. A forest inventory was conducted and generated the rigorous cubage of 100 separate trees in eight diameter classes by the method of Huber and tested 16 models of volumetric single and double entry and six of hypsometric relations. The best fit models were the Husch and Spurr in logarithmic form and the best height model was Stofel. Regarding the bark proportion it was found a higher percentage in individuals with the lowest diameter classes.
