Freshwater ecosystems are classified according to the movement of the water. This division is important both to nature studies and to operating and managing continental waters.


There are in the Serra two large spaces occupied by still water, Can Borrell and Vallvidrera, as well as a good number of small water points (cisterns, drinking troughs, etc.) distributed around the entire area. A marsh is a mantel of shallow, still water which has a completely different ecological dynamic to that of river spaces where the water is in movement. Understood as an ecosystem, a freshwater marsh combines underwater and floating plants, such as algae, rushes, water lilies, etc., which form a habitat where various aquatic birds can nest and spend the winter and small mammals, insect, amphibians and many other water loving species can live.


A key consideration behind the regeneration of the Vallvidrera marsh and environment was to establish an aquatic habitat for the amphibian populations that live in the Serra. For this reason, its banks were shaped in order to make it easier for animals to enter and leave and rushes and reeds were planted to provide safe hiding-places for fauna, as well as trees from different species to give shade and retain humidity.


The advice of the Catalan Herpetological Society ensured that the project for regenerating the marsh contained all the necessary ingredients to maintain the local amphibian populations.
