There are two general types of wetlands coastal sometimes called tidal and inland We find coastal wetlands near the ocean where saltwater mixes with fresh water to form varying degrees of brackish water In coastal wetlands the water levels vary throughout the day due to the changing tides Few plants grow well under these conditions so many shallow coastal wetlands are barren mud flats or sand flats However in some wetlands we can find grasses or mangroves that have adapted to the salty water 7
