An area of 5 hectares in La Pineda, in the municipality of Vila-seca de Solcina, consisting of a one-kilometre-long water channel. The actual wetlands occupy a much larger area as they include adjacent flood plains totalling some 17 hectares. Its interest lies in the fact that it is one of the few remaining examples of the marshes that covered much of the coastline in earlier times; for this reason it shares many of the characteristics of the southern wetlands. The prevailing vegetation is of reeds and rushes. The fauna includes two singular species, a fish known
as the fartet (Aphanius iberus) and the pond turtle, with one of the best preserved populations in Catalonia.
