The objective of this work was to develop a methodology to estimate volume in steres (st) without a previous log staking sampling. Data from a forest inventory and timber transportation were used. The "Empty Spaces Method" was adopted to illustrate the application of the information. Data on 91 plots of a pre-cut and transport inventory of a Eucalyptus grandis x Eucalyptus urophylla hybride planting volume, with na area of 243.1 ha, were utilized. The equations generated to estimate the volume in steres resulted in an error of -0.76% or -2.34 st/ha, for the equation generated from the "empty spaces method" deductions and of 4.54% or 11.61 st/ha, for the equation generated from application the Demaerschalk taper model. These results indicate that this methodology generates promising results, allowing to apply representative information on the use of the steres unit.
