La bassa de Fra Ramon

Route POI
Index card


This pond forms part of an old branch of the river Ter and was cut off by the works to channel the river in the twentieth century. Nowadays it only gets water from rain and the salt water which filters from the subsoil. The most important population of Spanish toothcarp (photo) in the area lives among the pond’s grasses. The Spanish toothcarp is a species which can cope with a wide range of temperatures and salinity, and it has been classified as being in danger of extinction in Catalonia. 

The pond’s plant life comprises species which tolerate high levels of salinity, such as glassworts and sharp rush. You will see the water has a colouration between yellow and red. This is not because of poor water quality, but rather because of incomplete decomposition of the leaves falling from underwater vegetation and surrounding plants.
