The objective of this work was to evaluate the performance of four species of eucalypt: Seed Production Area; Eucalyptus urophylla from Avaré; Eucalyptus pellita from Kuranda and Eucalyptus camaldulensis from Petford, planted in four arrangement (3x2m; 6x2m; 6x3m and 6x4m). The collection of the data was carried out with plants 9,4 of years old. It was evaluated the survival, DBH, height, volume per plant and volume per hectare. The results had shown that for the DBH and volume per plant increased with the increase of the arrangement; the volume per hectare presented inverse correlation; the height suffered influence only from the species; the survival presented difference between the spaces and the average was greater in the largest arrangement.
