Guadalquivir Marshes

The Guadalquivir Marshes (in Marismas del Guadalquivir or simply Las Marismas) are a natural region of marshy lowlands on the lower Guadalquivir River. The Las Marismas zone forms a large part of the province of Huelva, province of Seville and province of Cádiz in Andalucia, Spain. The area includes parts of the municipalities of Isla Mayor, Los Palacios y Villafranca, La Puebla del Río, Utrera, Las Cabezas de San Juan and Lebrija and Sanlúcar de Barrameda. Rice farming in this area produces 40% of Spain's national crop. Some areas are protected for wildlife and habitat, including dunes.
