Mangrove Forest
Mangroves play an important role in protecting the coast from storms, waves, and wind. Strong winds and seawater intrusion can be mitigated by mangrove stands, which can protect settlements, buildings, and agriculture. Mangroves have also been shown to play an important role in storm protection. Mangrove roots can bind to and stabilize mud substrates, trees can reduce wave energy and slow currents, and vegetation as a whole can trap sediment (Davies and Claridge, 1993 and Othman, 1994).
