Tides influence the vegetative development of mangrove coasts because mangroves favor tidal submergence. They are one of the few types of plants that can grow with their roots in soils that are continuously saturated with salt water.
Some mangroves have seedlings that germinate and begin growing before they drop from the parent tree. This characteristic is due to the fact that young plants need to have their leaves and branches above water. Thus, tidal range affects the growth of these types of coasts.
