Mangroves play a crucial role in coastal protection primarily by safeguarding shorelines from erosion and mitigating the impacts of storms. Their extensive root systems stabilize sediments, reducing the rate at which sediment is washed away by waves and currents. This stabilization is essential in maintaining the integrity of coastal landforms and preventing loss of habitat.

Additionally, mangroves act as a natural barrier against storm surges, which can be particularly destructive during hurricanes and typhoons. By absorbing wave energy and acting as a buffer, they help to protect inland areas from flooding and the force of incoming waves. This function is especially important in areas where development has occurred, as natural protective barriers have been compromised.

While mangroves do provide food for wildlife, contribute to water quality, and support fishing activities, their primary significance in coastal ecosystems lies in their unique ability to protect coastlines from erosion and storm damage. This protective function is vital for maintaining healthy coastal environments and supporting human communities that depend on stable coastlines.
