Resumo: A total volume equation, ratio volume equations and a taper equation were fitted using data from trees of Eucalyptus globulus Labill. felled over much of its range in Portugal. The models for each type of equation were selected from several possible candidate functions using fit and predictive ability statistics. Data analysis showed no effect of stand density, site index and tree age on parameter values. However, climatic regions where the data came from had a significant impact on some of the parameter values of those equations. Some of them were also significantly different between data coming from stands in first rotation and from coppiced stands. The same selected functional forms for each type of equation were fitted to data inside and outside bark and for total and ratio volume equations, models for the estimation of volumes including or not stump volume were also fitted.
