Factors, affecting the distribution of Mangroves

Environmental factors known to influence the distribution of particular mangroves

·        Evaporation rate

·        Frequency of saltwater inundation

·        Hydrology (Tides, currents, sea level and wave action)

·        Geomorphology (Catchment size, Estuary length, Sediment types and Slope)

·        Exposure to freshwater

·        Land runoff

·        Groundwater seepage

·        Land use in the adjacent catchments

 E.g. Cleared catchments tend to have increased sediment runoff

·        Oxygen availability

 E.g. aerobic or anaerobic sediment

·        Nutrient availability and pH

·        Feeding on seeds
             E.g. crabs selectively eat the propagules of certain mangrove species.
