The Bay of Cadiz or the Bahia de Cadiz has been considered as one of the incredible examples of the Atlantic tidal marshes particularly in the Iberian Peninsula. It is also a complex form of Natural Parks and a Ramsar site. Due to the position of the site in between Doñana and Gibraltar, the bay has been designated as one of the most significant coastal wetlands in the southern Europe. The bay is blessed of having been surrounded with natural habitats such like rocky islets and sandy beaches. It is also known as the sanctuary of the migrating waterbirds where they used this place for nursery, feeding and spawning.
There are about 200 species of birds that can be found in the bay. During the winter seasons, an estimated of about 65, 000 individuals can be seen in the bay. Macroinvertebrates are also visible during this time, specifically moluscos and crustaceans. But the most important species that can be found in the Bahia de Cadiz are the crustacean Artemia salina. These kinds of species are the foods for the young fishes as well as foods for the bird species.
Bahia de Cadiz was settled in the ancient times by the Phoenician; the Phoenicians are appointed as the first one who built the salt pans. Most of the big salt pans have been renovated into an aquaculture pools or became a natural habitats. While the original saltmarsh or out side the protected area has been drained as the way in developing for the urban development. In fact, it has already been surrounded by various urban centres. Many inhabitants are already seen here spreading through Cadiz, San Fernando, Puerto Real, El Puerto de Santa Maria and Rota. Myriad numbers of port facilities are also visible, that makes the place one of the tourism spots of Cadiz.
