They are specially adapted to withstand salinity, wave action, and can grow in poor soils. Mangrove thickets improve water quality by filtering pollutants and trapping sediments from the land, and they reduce coastal erosion. The main characteristics used to define the mangrove ecosystem are air and water temperature (warm), type of substrate (silt/clay), ability to provide protection from wave energy (from To quantify the long-term importance of live coral cover, we create two future reef profiles for both the barrier and the fringing reef.
