ABSTRACT.- The impact of forestry practices was evaluated on Eucalyptus?s growth variables and mortality dynamics. An experiment was conducted in Uruguay over sixteen years, sixteen spacing and thinning treatments were compared depending on the genetic material and productive objective. Tree height and diameter at breast height were assessed annually. All variables were analyzed using linear mixed models. Kaplan-Meier survival analysis and the Log Rank test were used to compare tree survival. © (2024), (Universidade Federal Rural do Rio de Janeiro (UFRRJ)). All Rights Reserved.
