The Boussuivre site : an environmental challenge and integral part of the project. <br />While this dale is where the Boussuivre flows, it equally represents major environmental stakes two emblematic species at home in the Boussuivre dale: the white-clawed crayfish Austropotamobius pallipes and the yellow-bellied toad Bombina variegata (on hind legs; and in belly-up defense position). Avoidance measures, reduction measures and compensating measures.
