A wetland is an extension of land that is temporarily or permanently flooded with water. This allows the formation of unique ecosystems where the natural diversity of the terrestrial environment is intermingled with that of the aquatic environment. A wetland is considered to be a place with a shallow water table, i.e. the distance between the water level and the land surface is very shallow. Wetlands can be composed of various geographical areas, such as lagoons, marshes, estuaries and swamps.

Thus, wetlands can be differentiated into 5 morphological types, such as marine, riparian, lacustrine, palustrine and estuarine. This classification depends on their origin, whether caused by the overflow of a river, by the mouth of the sea or by river flows. All types of flora and fauna can be found in wetlands, depending on their location and climatology. Some serve as a stopover point for many migratory birds, while others are the permanent home of others. Not to mention the presence of other animals, such as fish, mammals and mollusks.
