European otter Lutra lutra
Conservation
Although European otter Lutra lutra occupies an wide range in Europe, the species distribution was now restricted to some peculiar areas. The species declined everywhere in Europe.
Suffering severe habitat loss and destructions, otter populations were always threatened .

We surveyed otter presence since 1991 and studied the evolution of the specific range in France.
The efficiency of the umbrella species concept in conservation management was also tested using a top freshwater predator, the European otter.
