                         this study was to investigate the behavior of dendrometric 
                         variables of a commercial plantation of Eucalyptus benthamii 
                         Maiden et Cambage planted on an Inceptisol soil in Brazil for 
                         management purposes, based on geostatistic metrics and ordinary 
                         punctual kriging. A sampling grid of 70 x 70 m spaced over a 20 ha 
                         block was established in the municipality of Bocaina do Sul, in 
                         the state of Santa Catarina. Each sampling point was a circular 
                         plot of 10 m radius, where diameter at breast height (dbh), total 
                         height (h) of the first 15 trees and the 5 thickest trees were 
                         measured and the volume (v) of each tree was calculated by the 
                         Smalian method. The variables v, dbh, h and the dominant height 
                         (hdom) of each plot were subjected to geostatistical analysis 
                         based on semivariograms to detect the spatial dependence to these 
                         dendrometric variables. Only h and hdom presented satisfactory 
                         adjustment to the experimental semivariogram, with the spherical 
                         model better representing the spatial variation of these 
                         characteristics. Through kriging it was possible to estimate with 
                         high precision the variables hdom and h (r2 = 0.97, Syx = ± 0.04; 
                         r2 = 0.55, Syx = ± 0.21, respectively), in forest sites not 
                         sampled (validation data), thus providing subsidies for forest 
                         management purposes. Nevertheless, for dbh and v, it is 
                         recommended to conduct a higher sample intensity in order to 
                         identify spatial continuity.",
