Mangroves hold sediment well and restoration of mangrove woods can help reduce erosion of coastlines. Reduced erosion will help avoid sedimentation of the deeper shipping channels and port entries where, as water velocities slow down, sediments will naturally fall down. Mangroves are critical coastal ecosystems that impact our lives. They nourish biodiversity as nursery grounds for many coastal and marine species and support fisheries. They buffer coastal communities against extreme weather events such as hurricanes, stabilise coastlines and slow or reduce soil erosion.
