context_page_description: The Cristina Island marshes are located at the mouth of the river Carreras in the province of Huelva, Andalusia, in southern Spain. Created in 1989, the natural park has a surface area of 21.45 square kilometres, shared between the municipalities of Ayamonte and Isla Cristina.
context_section_description: It includes the west part of the marsh between the city of Isla Cristina, the reed area (cañas) and the limit of Ayamonte, with an area of 371.24 hectares. It is a degraded marsh, transformed long ago for the exploitation of table salt and currently developing aquaculture. These uses degrade the marsh, bringing homogenisation and impoverishment that weigh on its ecological value. Here stands a well-preserved tidal mill (es: El Pintado tidal mill) restored in 1995, presently used as a small visitors' center.
