Creno Lake

Details of the activity

Lake Creno, or Crena, is the lowest of the lakes in Corsica and the only wooded lake surrounded by laricio pines.Located in the Deux Sorru region, in the Monte Rotondo massif, the lake culminates at 1310 meters above from the villages of Guagno, Orto and Soccia. It is only accessible by walking paths.

With a maximum depth of 6 meters, the lake is fed by the Creno stream, which flows into the Fiume Grosso river, a tributary of the Liamone river.

Its particularity is to host on its banks a small carnivorous plant, Drosera, and to be flowered with non-endemic water lilies in season. This 2-hectare lake is a mountain lake, which is surrounded by stands of laricio pine (priority habitat) Creno lake is acidic and typical of peat bogs located in a forest environment, it is surrounded by stands of laricio pine, it is the only one of the Corsican mountains to be located in a forest atmosphere and therefore to correspond to this habitat. The water in this lake has an acidic pH of 6.5 and a high silica content. VS

It is also very original by the presence on islands of sphagnum (mosses) of carnivorous plants, sundews; The palynological interest is also important because the significant thickness of peat has made it possible to carry out pollinological analyzes (study of fossil pollens) making it possible to trace climatic sequences from the past.
