Loss and Gain in Mangrove Surrounding the Lençóis Maranhense National Park: An Integrated Approach Using Remote Sensing and SIG Data

Mangrove ecosystems surrounding the Lençóis Maranhenses National Park, Brazil, have experienced significant loss and spatial changes from 1985 to 2019, driven by aeolian dune dynamics, tourism pressure, and climate change. This study reveals a reduction in central mangrove areas, particularly near Caburé and Paulino Neves, due to sand dune encroachment and wind patterns, with northeast trade winds (6–8 m/s) playing a pivotal role in landscape transformation. Using remote sensing and GIS data, the research maps mangrove migration, attenuation, and stability, highlighting critical conservation challenges for this globally significant biodiversity hotspot.
