The places and biodiversity
The grand site of Cirque de Navacelles is made up of three southern Causses (Campestre, Blandas, and the southern Larzac), and borders on the Cévennes.
Two rivers cross it : the Vis and the Virenque, dry in some parts of their course. These particularities and the geographical position of the southern, continental, oceanic and mountainous influences give the « Grand Site » of the Cirque de Navacelles unique and exceptional bioclimatic conditions.
The altitude, the climate, the character of the rocks and human activities (essentially agropastoralism) have shaped a mosaic of environments favourable to an excepional biodiversity.
The schema below present the different environments :
• The open spaces on the Causse
• The gorges and the cliffs
• The river
• The « Cirque » and the hamlet
