This work evaluated exotic and native forest species in two plantation conditions: full sun and secondary forest enrichment strips, for generating technologies into incorporate to the productive process of degraded lands in the Amazonian region, to minimize the deforestation pressure on the natural forest. The analyzed data (DBH, height, volume per hectare and survival) refers to six years old species. In the full sun plantation, the species that presented the best performance was Ceiba pentandra, with means: DBH of 19.6 cm, height of 10.2 m and volume of 390.9 m³ ha-1. Hymenaea courbaril also presented satisfactory growth, with means: DBH of 11.5 cm, height of 10.8 m and volume of 144.8 m³ ha-1. In the secondary forest enrichment plantation, Carapa guianensis was the species that presented the best performance, with means: DBH of 8.3 cm, height of 6.4 m and volume of 54.8 m³ ha-1. Acacia mangium and Sclerolobium paniculatum presented better growth. However, the survival rates were very low in both plantations.
