Mangroves act as a reliable safety hedge against coastal calamities like tsunamis and cyclones primarily because of their extensive and complex root systems (such as prop roots and pneumatophores). These roots anchor the trees firmly into the muddy soil, ensuring they do not get uprooted even by high-velocity waves or strong storm surges. By standing firm, mangrove forests dissipate the energy of the waves and act as a physical buffer, significantly reducing the impact of the water on inland areas and human settlements.
