Mangroves are the characteristic littoral plant formations of tropical and subtropical sheltered coastlines. They are variously described as coastal woodland, tidal forest and mangrove forest. Generally speaking, mangroves are trees and shrubs growing below the high-water level of spring tides. Their root systems are thus regularly inundated with saline water, even though it may be diluted due to ...
