The Amapá mangroves (NT1402) is an ecoregion along the Atlantic coast of the state of Amapá in Brazil.The low coastal plain has been formed from recent sedimentation, including sediments deposited by the rivers and sediments carried northward from the mouth of the Amazon River by strong currents and deposited by the tides.The extensive mangroves grow on the newly formed coastal mudflats and along the edges of estuaries.They merge into freshwater várzea flooded forests further inland.The ecoregion is generally well-preserved, although excessive extraction of natural resources including timber and shrimps is a concern.
