Abstract: This study aims to perform the phytosociological characterization of the red mangrove Rhizophora mangle in the mangrove swamp of Praia do Mangue Seco, located in the municipality of Raposa, Maranhão, as a contribution to the knowledge of the structure and dynamics of mangroves. The predominant tree vegetation in the study area includes the species Rhizophora mangle, Laguncularia racemosa and Avicennia germinans, with a lower presence of Conocarpus erecta. For the study of the red mangrove R. mangle, the methodology used involved collections and analyses carried out to measure the structure of the trees, evaluate the leaf characteristics of Rhizophora mangle and analyze the sediment and water of the estuary. The herbivory rate and granulometric analyses of the sediment were analyzed, in addition to the analysis of water parameters, such as dissolved oxygen, turbidity, organic matter, pH and salinity. The results show that R. mangle has a heterogeneous structure, with older, more developed individuals and young individuals that demonstrate a new colonization of the species in previously degraded areas. The phytosociological characterization of R. mangle allowed us to verify that the dynamics of the mangrove is related to the impacts of the occupation of the area. Ecological restoration and environmental education actions are recommended, with conservation and sustainable management strategies, for the maintenance of biodiversity and well-being of local communities.
