The aim of this study was to define tree cut options in a sustainable basis for floodplain forests in the Amazonian Estuary. Data were obtained from the survey carried out in the forest lands of Wood Exports of Pará Ltda. - EMAPA Enterprise, located in Afuá County, North of Pará State. Sampling was performed in 29 plots of 5.000 m2. There were surveyed all trees, including palm trees with diameter at 1.30m above ground level (dbh) > 45 cm. Trade species with possibility to be harvested for presenting best phytossociological and qualitative indexes were: Virola surinamensis, Carapa guianensis and Hymenaea oblongifolia; among potential species Terminalia dichotoma was chosen; while in the non-trade species group, Eschweilera coriacea, Swartizia racemosa and Licania macrophylla were selected. Results showed that the forest management can be done by adopting a harvesting plan with a De Liocourt value 50% higher than the original (q = 2,61) one and removal of 30% of basal area, which corresponds to a potential income of US$ 3.945,40/ha.
