Abstract

This work aimed to evaluate the use of traditional models, profile and relative height method, for estimating the commercial volume of Anadenanthera colubrina (Vell.) Brenan. Data were obtained from scaling of separate lengths of the stem of 22 trees, using Smalian’s method. Tree stems were measured 0.1m, 0.30m, 0.70m, 1.0m, 1.30m above the ground and then every 1m. For purposes of method assessment and comparison, statistics were used that include percent standard error, bias, standard deviation of differences, in addition to graphic interpretation of residuals. Assessments showed that Stoate’s model is the most accurate, followed by Schumacher’s model. They also showed that the linearized Schumacher’s model reduced accuracy by an average 0.32%and that the relative height method was biased in this study.
