The objective of this study was to evaluate the performance of Eucalyptus grandis, E. dunnii, E. benthamii, E. badjensis and E. urograndis hybrid, in relation to survival and forest productivity in an experimental area located in Alegrete county, Rio Grande do Sul State, Brazil. The forest-livestock integration systems were composed of triple lines of trees, planted in 3 m x 2 m spacing, apart 30 m of each line, resulting in an initial density of 417 trees ha-1. This corresponds to 22.2% of the area occupied by the tree lines, with the rest of the area allocated to livestock (77.8%). Diameter at 1.3 m (DBH) and tree height were measured annually, up to seven years of age. A completely randomized experimental design with six replicates per treatment and the Assistat software were used for the statistical analysis. It was possible to highlight survival, growth and productivity of Eucalyptus grandis and E. urograndis hybrids, although the performance of. E. dunnii and E. benthamii was not good. E. badjensis should not be recommended for planting under environment conditions analogous to this research.
