Forest milieux   Open milieux    Wetlands    Rupiculous milieux   Cliffs and rocks   Underground   Lofts of buildings and    ruined castles   Underground   © Jean-François Schneider Underground milieux (mines, military fortifications...) in the area serve as winter home for numerous bats including the Greater Mouse-eared bat (Myotis myotis), Long-eared Bats, Barbastella (Barbastella barbastellus) Barbastella, © Michel Rauch and Geoffroy's Bat (Myotis emarginatus) amongst others. These fascinating sites provide a very specific environment given their hygrometry, temperature and the darkness that reigns. Geoffroy's Bat, © Jean-François Schneider Besides the bats that come here to overwinter, there are also woodlice, spiders (Meta sp.), Méta © SYCOPARC moths (Scoliopterix libatrix) and salamanders where the area is partly under water.
