The purpose of this paper is to evaluate the agro-environmental sustainability potential of productive agroforestry units in tidal river floodplains. The methodology employed forest inventory techniques, soil collection and laboratory analysis, questionnaires, field observations and budget sheets. The indicator variables are relative to climate, soils, sociological plant structure, agroforestry's productive potential and the generation of income. Results revealed that climate and soil are not limiting factors. Approximately 27% of the floristic composition is commercial species, making up over 92% of the total tree population having low timber extraction potential and a diversity of non-timber products. Estimated gross income reached sums of R$2,000.00/ha/year. The agro-environmental sustainability potential of the productive units is median and was measured by evaluating the indicator variables on a point system and placed within a previously established level of sustainability.
