The objective of this study was to evaluate the accuracy of the Criterion RD 1000® optical dendrometer in a crop-livestock-forest integration system for measuring total volume and sections with bark of eucalyptus trees. Selected trees were felled, having their actual strict volumes obtained. The Smalian method was used for destructive Non-destructive scaling was using carried out using criterion. Bartlett’s test for total volume (p-value 0.5125) and diameter along the stem (p-value 0.1891) was found to be homogeneous. There were no statistical differences between the total volumes obtained by the destructive method compared to the non-destructive and the average form factor. The diameters along the bole obtained by the destructive scaling were the same as those obtained by the non-destructive scaling. For the volume by sections of the bole, it was verified that only in the sections closest to the top and considering the volume up to the top, there was difference with the actual volume. However it corresponded to a small proportion of the total volume (9%). Measurements obtained with the Criterion RD 1000® showed no trend, providing efficient measurements for both diameter and volume along the bole.
