The sandbank of Fortalezinha is located in the SE portion of the Algodoal/Maiandeua APA, municipality of Maracanã and composes the coastal plain of northeastern Pará. The Paraense coast presents elongated bays, rivers with wide mouths ("drowned" valleys), sinuous drainage and extends from the Marajó Bay to the Gurupi river bay, on the border with the state of Maranhão. It is composed of Tertiary (Pirabas and Barreiras Formations) and Quaternary (Post-Barrier Sediments and Recent Fluviomarine Deposits) sediments. In order to characterize the subenvironments of the coastal plain, two morpho-botanical transects were made perpendicular to the actual coastline, and 9 units were evidenced: Supramaré Zone, Sandy Beach Cord, Reverse of Beach Cord, Dunes Field 1, Hydromorphic Space, Mangrove Swamp, Dunes Field 2, Lake and Low Coastal Plateau (CNPq, FNMA/IBAMA)
