ABSTRACT Planting of forest species of timber interest helps to reduce the deforestation pressure on the Amazon forest, promotes sustainable development of the producing region and generates ecological benefits. The objective of this work was to evaluate the survival rate and growth of four native (Swietenia macrophylla, Parkia decussata, Dipteryx odorata and Jacaranda copaia) and one exotic (Acacia mangium) species in monospecific plantations (spacing of 2 x 2 m) established on areas previously used for grazing, in Itacoatiara, State of Amazonas, Brazil. When the trees were four years old, we collected biometric data [height at 1.30 m (DBH, cm), crown projection area (CPA, m2), total height (Ht, m), commercial cylinder volume (Vcyl, m3 ha-1)], and qualitative data from visual diagnosis [survival rate (S, %), nutritional status (NS, G = good, D = deficient, %), and phytosanitary status (PS, S = satisfactory, N = non-satisfactory, %)]. Three plots of 128 m2, with 32 plants each, were evaluated for each species. Jacaranda copaia, followed by Dipteryx odorata and Parkia decussata, were the recommended species for planting in areas with edaphoclimatic conditions similar to those of the present work, due to their better performance according to most of the variables.
