This study aimed to fit mathematical models for estimating commercial volume with bark for species of an Upland Dense Rain Forest located in southern of the state of Roraima, Brazil. It was cubed by Smalian method an amount of 122 trees of 18 species with diameter at breast height (DBH) higher than 50 cm. Nine models were adjusted by least squares methods, and selected on the basis of the adjusted determination coefficient, standard error in percentage, F value and graphical analysis of residuals distribution. Schumacher-Hall model was selected. Kopezki-Gherardt model can be used when data from commercial height are not used.Downloads
