Cows, goats and sheep used this common lands until the 1960s. Then cereal crops were planted in the most fertile areas. Scrubland and woods took over the other areas, which were stony and steep.

Nowadays, the Pulsatilles trail reveals a typical landscape where the limestone slabs cover the surface around the Stone of God and the Devil, standing like strange sentinels, vestiges of the ice age.

Berry shrubs and flora adapted to a thin layer of arid soil flourish there. In the spring, walkers might come across lizards, grasshoppers and butterflies, and see the first lily of the valley, grasses, orchids, ferns, spurge and, of course, the site's emblem, the red pasqueflower, a rare and protected wild anemone with a beautiful dark garnet colour.

Working together for biodiversity:
IThe involvement of local people allowed the biodiversity to return! This 100ha Sensitive Natural Area, at the west of the village, is managed by politics with hunters (warrens building, trails maintenance), naturalists from the ADPE professional training organisation and Lo Parvi (scientific monitoring, educational events), farmers (grazing, controlling shrubs), quarrymen, neighbours, and, of course, hikers.
