There are up to 26 different marine habitats along the Catalan coast. However, until now, some were unknown, or, despite their existence, the exact location and size of their habitats had not been identified. To fill this historical information gap, a pioneering project was launched four years ago to produce a detailed x-ray of the Catalan seabed, which was presented this Thursday: the map of marine habitats of Catalonia. "For the first time, we have information on the entire Catalan coast, from Portbou to Alcanar," explained Sara Pont, head of the heritage planning service at the Department of Environmental Policies and Natural Environment.
