If you make a detour to the Col de Gleize, you may well see some mouflons. An ancestor of the sheep with ammonite horns, it was introduced from 1949 into the Alps from herds in Corsica and central Europe, and seems well settled in the Chaudun area. Even though the European Union recommends strict protection of the mouflon, it is still hunted during the hunting season. Its populations are ill-adapted to extreme Alpine conditions and can fluctuate according to the winter weather.
