Mammifères aquatiques et semi-aquatiques introduits en France. Risques et conséquences

Abstract

The French mammal fauna comprises about a hundred species, 7 of which are aquatic or semi-aquatic introduced species. The Canadian beaver must be added to this list, but it has recently been eradicated. These 8 species belong to 7 families and 3 mammalian orders. The risks linked to these animals are mainly of three categories : economical, ecological and sanitary. A few examples are given to illustrate those situations.
