About

At the moment, management and restoration of lakes are based on short-term (often less than a year) data. A high number of restoration techniques are proposed but each has inconvenient. A lake is a unique ecosystem and no solution can be used in all lakes having similar problems. To propose the best management and restoration solutions, the natural variability and the baseline conditions should be known. This can only be achieved with paleolimnology. Lake sediment is an archive. Using biological and physico-chemical parameters preserved in sediment, the baseline conditions can be defined and the actual causes of changes through time can be appropriately defined. Based on these data, the long-term management and restoration solutions can be proposed.
