In summer, this part of the valley is occupied by a herd of more than 1,000 merino sheep. Unlike the herds that inhabit the valley of Orgère and Estiva, this herd spends the winter on the pastures of Crau in the Bouches-du-Rhône and it is only from June that it returns to the Alps and gradually climbs from the hamlet of Polset to graze on the alpine pastures.
